Application of V Seal

Application of V Seal

DSH-Application of V Seal

The V seal is a simple, universal, elastic surface type seal, made of Ding nitrile, which can be the main sealing element, pollutant remover or spare seal in the application.

These seals are mounted on the shaft, and their thin cone-shaped lip seals are at right angles to the shaft, opposite the surface or the bump surface.There are no special requirements for the surface finish of the shaft seat, and these seals act as flingers because they have an interference fit on the shaft and rotate with the shaft.Incorrect alignment of the shaft with respect to the secondary surface is tolerable, and if the shaft is not circular or eccentric, the V Seal also provides a reliable seal.

When using these seals, it should be remembered that the amount of axial displacement that the shaft can shift depends on the allowable displacement of the V seal relative to its reverse surface.These seals are made entirely of elastic materials without fabric or sheet metal reinforcement.They are therefore particularly easy to install.Depending on the size, they can be stretched and can be pushed to other parts of the arrangement, such as flanges, pulleys and even shells.This is a very valuable feature of these seals, especially in the case of repair.

The V seal is an ideal seal to prevent contamination of dirt, water or oil splash, and is also an excellent grease holder.Easy to install by hand and kept in place by their own tension, they can be used as main or sub-seals for oil seals, mechanical seals or mazes.Due to its unique features, V-shaped seals are widely used in machine tools, ships, automobiles, metallurgical machinery, chemical machinery, construction machinery, construction machinery, plastics, agriculture and different instruments.

There is no industrial area where V seals are not used.From individual seals for repair or maintenance to quality assurance applications in aerospace, automotive or general engineering.These seals are widely used in many industrial and commercial fields.Darcoid Nor Cal Seal offers high cost-effective adhesives and seals with high productivity for Parofluor, Parofluor ULTRA, Kalrez, Chemraz,A single v-shaped seal can play an important role in sealing in two directions and is suitable for different sealing media such as oil, water, gas, chemical media and other mixed media.Darcoid maintains innovative, high-quality accessories for your industry leadersend machinery.

The Basics Of Hydraulic Couplings–Threads And Seals

DSH-The Basics Of Hydraulic Couplings–Threads And Seals

Hydraulic coupling, also known as accessories, plays an important role in hydraulic equipment,like threads and hydraulic seals.The coupling is a device used to connect the hose to the hydraulic system.If there is no safe connection used to push the fluid through, the hydraulic machinery will not be able to perform.Normally, the coupling is made of metal and connected to the hydraulic hose assembly.

 

There are two components in the coupling, one is the dry end and the other is the thread end.The rod end connected to the hose and thread end is connected to the hose assembly and hydraulic equipment.Depending on the type of hose and the fluid pressure through the hose, different coupling is used.When manufacturing hydraulic hose assemblies, there are many ways to connect the joints.There are two types of thread configurations on the coupling: male and female threads.In order to establish consistency in the industry, the thread ends are standardized.

 

Today, the threaded end design can comply with three main types of hydraulic seals: the threaded seal, the mating angle seal and the “O-ring” seals.The first two are metal.to-Metal contact seal, the latter “O” ring uses rubber-to-metal seal.The easiest coupling to install is with low-pressure hoses.These joints simply lubricate and push into the end of the hose.When the hose is tightened under pressure, the inclined ridge on the coupling grabs the hose.Hoses designed for high pressure are reusable and permanent joints.Reusable joints are connected to the hose using a sleeve.Ferrule is a ring that is screwed on the hose cover with a wrench.The rod is inserted into the tube of the hose with the thread on the sleeve.The compression of the hose between the rod and the sleeve holds the coupling on the hose.Once, reusable coupling was the most popular coupling in the market, but the popularity of permanent coupling exceeded them.Hydraulic assembly-Manufacturing equipment makes it easier and faster to install permanent coupling.

 

Typically, the cost of a permanent coupling is lower than that of a field coupling.The permanent coupling requires special equipment called “Curlers” in order to attach them to the hose and apply force perpendicular to the side of the sleeve.When the coupling is curled inward, the serration on the sleeve pierces the hose cover and goes deep into the wire reinforcement.Both have permanent coupling piece and two-Configuration of pieces.One piece, the coupling is pre-Assembled and manufactured with a sleeve permanently attached to the rod.Two-The segmented coupling consists of a rod and a separate sleeve.When using two-Part coupling, it is important to match the sleeve with its proper Rod and hose.Permanent coupling is required for proper installation.

Tips To Help You Decide About Seal Materials

DSH-Tips To Help You Decide About Seal Materials

You might want to know how many sealing materials are available.Don’t worry, there are others who want to know how plastic O-rings, gasket seals, lip seals and other useful seals are made.Like everything else, seals are made to complete special features.They can be used to provide two things to close, connect, or save something.This is why the availability of different sealing materials is important.

 

Seals are used for different materials and applications.Therefore, there are seals for plastic O-rings, gasket seals, lip seals, Teflon seals and graphite seals.Each of these adhesives is made for different applications.In addition, it is considered that the efficiency of the seals depends on their materials.Perhaps, that’s a good reason why the oil seal material is different from the roof seal material.

 

Plastic O-ring-This is one of two mechanical seals on the market.They are the most common type of seal, also known as filler or ring joint due to their shape.They are also often used to hold liquids.Some of the sealing materials used to form toric joints are dinnitrile and silicone.Ding nitrile seals are often found in cars and other cars.This is because it can resist liquid hydraulics, water and different petroleum products.On the other hand, the rubber silicone does resources used to make O-rings.

 

Gasket seal-This type of seal is the best choice to prevent leakage.It provides an effective seal between the joint and connection of the pipe and the not have the resistance of the front material.But if there is something remarkable about it, it is that it is able to withstand different harsh temperatures, which makes it an ideal seal for use in pots and other cookware.

 

In addition, trifluoride ether of Teflon, natural rubber and fluorine rubber is some of the other popular pipe.Therefore, it also needs a special tool to apply it.This type of seal is made up of different materials.It can be made of rubber, Silicon asbestos, metal, fiberglass or plastic polymer.These materials are applied according to the function of the seal.There are also washers made of neoprene.This chemical is easily similar to rubber with stronger and more stable properties.Neoprene seals are widely used in medical fields such as wrist seals and braces.Rotating tools and components are best sealed using a lip seal or a radial shaft.Some of their examples include hydraulic pumps, steering wheels and axles.

 

Through the application of lip seals, these parts and tools can be used for a longer time and perform better.Although rawhide is used in traditional radial shafts, modern lip seals are made of elastic materials.This chemical is a polymer with a lot of yield pressure that creates elasticity.Of course, there are other seals in use and production all over the world.Some of them may use some of these sealing materials, while others may use other materials.

Axial Mechanical Seal

Axial Mechanical Seal

DSH-Axial Mechanical Seal

 

The axial mechanical seal of the present invention includes a shell with a closed circular space, which contains a fluid under pressure.

 

When subjected to heavy vibration, the carrier of the sealing ring and the supporting sealing ring cannot be placed in the axial direction and radial direction in the ring space;A series of pockets are placed in the housing on a regular basis and each pocket includes a compensation element that is in contact with the fluid under pressure, thus, the sealing ring and its carrier in the fluid displacement ring space generated by the axial movement of the fluid are accepted.

 

In an axial mechanical seal, including a shell with a circular internal space fluid subjected to pressure, the sealing ring and the carrier mean that the sealing ring is supported in said ring space, when subjected to heavy vibration, said sealing ring and said carrier means that axial direction and radial direction cannot be placed in said ring space: a series of pockets that are regularly disposed of in said housing;The compensation device means in each said pocket, the compensation device refers to the part consisting of an elastic yield device in contact with the fluid under pressure;Said elasticity means yielding in said pocket to accept fluid displacement due to the axial movement of said sealing ring, said carrier means in said ring space.

 

Basically, the axial mechanical seal includes a pair of flat sealing surfaces forming part of the rotating seat ring and fixing the sealing ring;By applying force (usually a spring) to one or two of the planes, these planes are urged to join in a fluid seal.In addition, these surfaces are subject to the action of the pressurized fluid contained in the sealed enclosure, and the rotary axis extends into that sealed enclosure.Vibration transmitted from the machine to the seal can cause difficulties, especially in large equipment such as turbines, stern tubes.

 

According to the frequency and amplitude of these vibrations, periodic increases will occur.The falling off of the sealing surface causes a leak between the sealing surfaces.In extreme cases, this effect can result in very short suction and discharge times in the sealing gap, and high-speed leakage flow and extremely high pressure difference can lead to erosion of the sealing surface and rapid damage to the sealing.These vibrations can be divided into radial and axial motion.Radial movement leads to radial sliding of the sealing ring and seat ring on each other’s surface;In most cases, however, these movements are accepted by standard axial mechanical seals.

 

On the other hand, the axial movement produces force in the seal area, which can be divided into mass force and hydraulic force.In order to reduce the mass force, parts that are affected by this force are usually made as lightly as possible.In addition, by adjusting the load of the spring to urge the surface in contact with each other, the resonance area can be avoided.The hydraulic power is far greater than the mass force, because a large amount of fluid must be displaced and pumped in a very short time interval.Because the above-Mention of regular elevatorsOff, these hydraulic forces can cause the sealing surface to open continuously, because the force in the spring cannot restore the contact of the sealing surface in a short time interval.This situation leads to constant and very high leakage, eliminating the advantages of flow leakage and high life of axial mechanical seals compared to other types of seals.Therefore, the purpose of the present invention is to provide a seal capable of tolerating vibration without the negative effects described above.

 

Thus, the present invention provides a series of pockets, each of which has an axial mechanical seal and compensation device.The compensation device consists of an elastic device that contacts the fluid under pressure and yields in the pocket, to accept the fluid displacement caused by the axial movement of the sealing ring and the sealing ring carrier when they are subject to high vibration.From the detailed description given below, the scope of application of the invention will become apparent;However, it should be understood that a detailed description, while indicating the preferred embodiment of the present invention, only the various changes and modifications within the spirit and scope of the invention will become obvious to those who are good at art.Basically, the present invention provides a compensator in an mechanical seal housing, which is able to accept displaced fluid without high flow rate and force, and process the fluid according to frequency.

The role and significance of hydraulic oil seal?

The role and significance of hydraulic oil seal?

In the hydraulic system and its system, the sealing device is used to prevent leakage of working medium and intrusion of external dust and foreign matter. The element that plays the role of sealing, that is, oil seal. Dongsheng Seal Company sorted out and shared

 

Leakage will cause waste of working media, pollute the machine and environment, and even cause mechanical operation failure and personal accidents of equipment.

 

The internal leakage will cause the volume efficiency of the hydraulic system to drop sharply, and the required working pressure cannot be reached, or even the work cannot be carried out.

 

Invading tiny dust particles in the system can cause or aggravate the wear and tear of the friction pair of the hydraulic element, further leading to leakage.

 

Therefore, Oil Seals and Sealing devices are an important part of hydraulic equipment.The reliability and service life of its work is an important indicator to measure the quality of the hydraulic system.

 

In addition to the gap seal, the oil seal is used to control the gap between the adjacent two coupling surfaces below the minimum gap that the liquid that needs to be sealed can pass.

 

In the contact seal, it is divided into self-sealing type and self-sealing type (Lip seal)Two.

So, what kind of sealing problems do several common hydraulic cylinder sealing rings have?

 

Q: What is a qualified hydraulic sealing ring?

 

A: 1.The material is dense and it is not easy to leak working media or materials.Because the sealing ring itself is to prevent leakage.2.Good adaptability and stability for working media.3.With proper mechanical strength and hardness, it is almost unaffected by the working medium.For example, the commonly used sealing ring is made of carbon-N, silica gel, ethylene-propylene oxide, fluorine glue, etc.The reaction of different materials to different working conditions is not the same, such as the oil-resistant and wear-resistant nature of the material, high temperature resistance of silica gel, ozone resistance, etc.4.Good compression, small permanent deformation.5.Good temperature adaptability, no softening, no decomposition at high temperature, no hardening at low temperature.6.The friction coefficient is small and the wear resistance is good.7.Good corrosion resistance, no softening at high temperature, no decomposition, no hardening at low temperature, no brittle cracking.8.The softness and elasticity that fit with the sealing surface are good.9.Internal ozone and aging resistance are good, and the service life is long.10.Good processing performance, low price.

 

Q: How to choose the hydraulic sealing ring correctly?

 

A: 1.The V-shaped sealing ring is an elastic rubber sealing ring acting in an axial direction and is used as a pressure-free seal for the rotating shaft.The sealing lip has good activity and adaptability, which can compensate for large tolerances and angle deviations, prevent internal grease or oil leakage from the outside, and prevent the invasion of external splashing water or dust.

 

2. O-type sealing ring is mainly used for static sealing and reciprocating sealing. For rotary motion sealing, limited to low speed rotary sealing device. The rectangular sealing ring is generally installed in a groove with a rectangular section on the outer circle or inner circle. The Y-type sealing ring is widely used in reciprocating sealing devices. In addition, there is a spring tension (spring storage) sealing ring, which is to add a spring to the PTFE sealing material, with O-Spring, V-Spring, U-Spring
