Are You Familiar With the Oil Seals?

Are you familiar with the oil seal? Simply speaking, it is an element that is used to seal the oil. It is the very important component for all kinds of mechanical equipments. Although it is small, its application is quite wide. To some degree, its quality and properties have a direct influence on the reliability of the mechanical equipment. Some of these seals have a year’s operation life. Some can only be used for several months. These seals are easily out of service because of the oil leakage. As a result, the working efficiency of the mechanical equipment is seriously affected. Meanwhile, the production cost is increased and the environment is polluted.

Generally speaking, the working principle of the oil seal is simple. In the free condition, the inside diameter of the oil seal’s lip is smaller than that of the shaft collar. And it has the shrink range. After this seal is installed, the interference pressure and the shrinkage force will generate the radial thrust on the slewing axis. When this seal is in operation, the lip of the oil seal will form a seal belt under the influence of the radial thrust. Under the pressure of the lubricating oil the fluid permeates the cutting edge of the oil seal and a layer of oil film is formed. The oil layer can prevent the oil leakage and play an important role in sealability.

During operation, there are a lot of factors that result in the oil leakage. The bad sealability of this seal is the main factor. When the shaft is abraded seriously and there is a groove on the shaft, the oil seal will lose its sealability. Even through people change a new oil seal, the sealability still can not be improved. When the contact pressure between the lip and the shaft is reduced, the shrink range becomes very small and thus the sealability becomes very weak.

How to solve the above-mentioned problem will be introduced as follow. First, the basic method is to grasp the knowledge of the oil seals. Then people can identify the quality and function. Second, check and maintain this seal regularly. As far as we know, the oil seals are often used in the harsh working conditions. The difference in temperature is very big and there is a lot of dust in the environment. If people do not examine them, they are easily out of service. Third, if the shaft collar is seriously abraded or the rubber of this seal becomes old, the related components should be repaired or changed immediately. Fourth, the unused oil seals should be kept properly. Or else, the seals will be easily stained with the dust or greasy dirt. Then they will be out of service.

The Introduction of Stainless Steel Valve

A so-called stainless steel valve is a valve, mainly made of stainless steel, which regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. The types of stainless steel used in the body of a valve are 301, 304, 316, 304L and 316L. According to international standards, they also can be classified into CF8, CF3, CF8M and CF3M. There are all kinds of the stainless steel valves, such as gate valve, ball valve, butterfly valve, check valve, plug valve, needle valve, baiting valve, steam trap, air-operated valve and so on.

As far as we know, stainless steel is a common name for metal alloys that consist of 10.5% or more Chromium (Cr) and more than 50% Iron (Fe). The chromium content in stainless steel alloys is what generally prevents corrosion. It helps to procrastinate the iron to rust by oxygen and water. It works by reacting with oxygen to form a tough, adherent, invisible, passive layer of chromium oxide film on the steel surface. Besides, the additions, such as nickel are used to raise the general corrosion resistance required in more aggressive usage or conditions.

Because of these components, it is famous for its resistance to corrosion and staining, low maintenance, relatively low cost, and familiar luster and it is an ideal base material for a host of commercial applications, especially for valve application. On basis of properties of the stainless steel, stainless steel valve has the features of corrosion-proof, rust-proof, water-proof and durability.

Therefore, it is widely used in a lot of industries where the resistance to corrosion is required, such as chemical, petrochemical, oil, paper-making, mine, electricity, gas, food, pharmaceutical, water supply, mechanical equipment, electronic, urban construction and so on.

Nowadays, stainless steel valves have been the necessary products in all kinds of fields. However, there are only a few valve manufacturers who reach the international standard. So when people purchase this valve, they must require the seller to show the certifications for production. Through this way people can avoid buying the unqualified products. What’s more, this valve from Japan, Germany, U.S., U.K. and Shanghai in China are the better choices for purchasers, because most of them from the above places are in line with international standards. As for the famous brands, there are Kitazawa of Japan, Venn of Japan, Top of Germany, VTON of U.S. and Shanghai Xiandie valve in China.

4 Ways to Minimize Hydraulic Cylinder Failure and Repair Costs

As a product group, hydraulic cylinders are almost as common as pumps and motors combined. So if you operate a lot of hydraulic equipment, it’s likely that cylinder repair expense is a significant portion of your total operating costs.

According to some studies, up to 25% of mechanical equipment failures are failures of design. If we apply this to hydraulic cylinders, then as many as one in four hydraulic cylinders are not adequately designed for the application they’re operating in.

This doesn’t mean that the cylinder won’t do the job asked of it, it will – but not with an acceptable service life. So if you have any cylinders that don’t last like they should you may need to address one or more of the following four issues:

#1. Bent Rods

Bending of cylinder rods can be caused by insufficient rod diameter or material strength, improper cylinder mounting arrangement or a combination of all three. Once the rod bends, deforming load is placed on the rod-seal. This increases leakage and ultimately results in premature failure of the seal.

The allowable rod loading for a cylinder in an existing application can be checked using the Euler formula.

#2. Rod Finish

The surface finish of the cylinder rod has a significant effect on the life of the rod seal. If the surface roughness is too low (smooth), seal life can be reduced as a result of inadequate lubrication. If the surface roughness is too high, contaminant ingression is increased and an unacceptable level of leakage past the rod seal can result.

In the context of extending cylinder service life, think of the cylinder rod’s surface as a lubricated, wear-surface and treat it accordingly.

In some applications, the use of an alternative rod surface treatment with superior mechanical properties to conventional hard-chrome plating, such as nickel-chrome plating or High Velocity Oxygen Fuel (HVOF) metal spraying, can increase the service life of the rod and its seals.

And in some cases, the installation of a shroud or bellows to protect the rod surface and its seals from impact damage and contaminants, can afford similar life extension benefits.

#3. Ballooned Tubes

Ballooning of the cylinder tube is usually caused by insufficient wall thickness and/or material strength for the cylinder’s operating pressure. Once the tube balloons, the correct tolerance between the piston seal and tube wall is lost, allowing high-pressure fluid to bypass the seal. This high velocity fluid can erode the seal and localised heating caused by the pressure drop across the piston reduces seal life-the end result of which is: premature failure of the piston seal.

#4. Insufficient Bearing Area

If the surface area of the bearing (wear) bands in the gland and on the piston are insufficient to adequately support the side thrust transferred to the cylinder, excessive load is placed on the rod and piston seals. This results in deformation of the seals, and ultimately, their premature failure.

Repair or Redesign?

To summarize the above: not all hydraulic cylinders are made equal. So if you have any hydraulic cylinders that suffer recurring failure, it’s likely that design modifications are required to break the vicious circle of failure and repair.

The Process of Precision Metal Stamping

Precision metal stamping is the process of making 3-dimensional metal parts, lettering and other embossing. This is a kind of metal stamping used mostly for decorative purposes. It is similar to normal metal stamping, which is the process of molding metal into different shapes and sizes. The products obtained through metal stamping are used as components for some larger products in other industries. The most common metals and alloys used for precision metal stamping are copper, aluminum, brass, beryllium, nickel, nickel silver, steel, stainless steel, phos bronze and titanium.

Precision metal stamping is applicable to many industries like computers, electronics, electrical, dental, aerospace, instrumentation, military specs, defense, telecom and automotives. There are many methods in precision metal stampings for producing stamped prototypes. Blank creation is one such method. Blank creation involves the creation of a flat state of the component. The flat blank sheet is then used to make the part’s features. In blank creation, there are many processes
like nibbling, chemical etching, water jet cutting, wire EDM, punch and die.

There are also many methods for producing prototypes by precision stamping. The type of method used depends on the size and intricacy of the parts to be produced as well as the number of prototypes. Single part transfer is one such method in which single parts are transferred from one station to the next for blanking and metal forming. The main advantage with this method is the cost effectiveness. One single, standard system can be maintained for designing, manufacturing and holding tooling inserts. However, this system is slow because it needs individual prototype parts. The other method is the progressive strip prototyping which involves the automatic transfer of the metal from one stage to the next.

Precision metal stamping can be done at very high speeds and even up to 1,200 strokes per minute. Precision metal stamping gives several advantages like the ability to use any metal or alloy and creation of components with very precise dimensions and shapes. Plating can also be very precise which is helpful when working with precious metals like gold and palladium.

Plate Lifting Clamps

So, what exactly is a plate lifting clamp? The solution to this question is simple, a plate clamp is a piece of apparatus which is intended specifically for lifting and handling sheet materials such as large sheets of steel for instance. You will discover differing kinds available, the most typical types are the vertical and horizontal plate clamps that lift the sheet materials in their respectively named position, universal hinged plate clamps can also be found which includes both of the above’s properties.

Every kind of plate lifting clamp is available in a range of designs, some are designed for thin sheets, some are extra heavy duty, some have adjustable jaws, are hinged, have high grip properties or have an added safety lock, some versions are referred to as non-marking as they should lift sheet steel without leaving any marks at all. Some have smooth jaws, some will have hardened steel jaws, some might have protecting rubber linings to reduce marks and some models will possess a roller bar to help with mark reduction. So there is a version for just about every situation.

We will now explore each main type more closely

A vertical plate lifting clamp is commonly used to move sheet materials in an upright, vertical position nevertheless some versions enable the sheet to be turned through 180 degrees. If you want to move large sheets that could yield easily then it is common practice to make use of 2 or more plate clamps at the same time in conjunction with a spreader beam ensuring regular spacing for stability. The vertical plate clamp consists of two jaws held in a rigid housing, one jaw is unchanging but the second jaw is moveable in order that the jaws can be adjusted and tightened until they fasten securely on the sheet material, the spring loaded cam action ensures the clamping strength which needs to be double the weight of the material being lifted. The clamp also needs to be capable of withstanding a static load of two times the safe working load limit with no lasting deformation and 3 times the safe working load limit before the load is released. It is also crucial that it’s not possible to accidentally release the load.

The Horizontal plate clamp

Plate clamps of the horizontal variety are almost always utilised in a minimum of two’s, occasionally more based on the size and also thickness of the sheet as drooping may easily occur if not supported in the approved manner. Because they are used in multiples, a spreader beam is usually used, but chain slings can also be used. shorter sheets could be lifted by means of 2 clamps, one on each chain sling leg, as it is lifted the slings legs exert a horizontal force; larger sheeting could use 4 clamps together with a 4 leg chain sling, however the forces could cause the material to bend and buckle since it is only supported around the edges.

Hinged or universal plate lifting clamps can permit long sheet materials to be handled, with hinged hook rings they can be used for handling plate at a variety of angles. It could actually lift plate from the horizontal position and put down in the vertical position or visa versa. The hinged hook ring ensures the necessary gripping pressure in every position, but the load capacity is reduced.

Most kinds of plate lifting clamps are incredibly service friendly due to the fact that they have got exchangeable parts, and repairs and servicing can usually be carried out promptly by a competent lifting gear business.
Our articles will provide useful information and answer the commonly asked questions; why, how and where particular lifting gear products are used.
