LNG Lip Seal is a type of spring energized seal, commonly used in LNG (liquefied natural gas) filling guns. Currently, it can be installed with most of the brands in China and overseas. The jacket of the LNG Fueling Nozzle Seals is made of polymer materials, which can withstand a low temperature of - 200 degrees. It is designed with a stainless steel anti-corrosion spring with special low temperat...
Spring lip seals have been used for many years. Spring lip seals are used in a manner similar to conventional elastomer seals, such as o-rings. Elastomer seals often fail due to conditions that often occur in their operating environment, such as chemical corrosion, extreme high or low temperatures, extrusion, friction, or compression set. However, spring lip seals have different structures and do ...
BOP seal, also known as Blowout Preventers Seals, is generally used for large special valves or mechanical devices to seal, control and monitor oil and gas wells to prevent blowout and rig safety. Because there are many uncertain factors in the formation and they are very complex, each drilling operation has the possibility of blowout, which puts forward higher requirements for well control techno...
Working Principle and Characteristics of Piston Pump in High Pressure Washer The piston pump moves forward and backward through a fixed seal. The piston pump relies on the reciprocating motion of the piston to make the working volume of the pump chamber change periodically, so as to realize the suction and discharge of liquid. The plunger pump seal is installed on the plunger through a smooth cyli...
Main performance The section of Y-ring seal is Y-shaped, which is a typical lip seal. It can be divided into wide type, narrow type and Y type according to the different proportion of height and width of the section. According to whether the two lips are equal in height, they can be divided into Yx seal rings with equal height lips for shafts and holes, Y seal rings for rods and holes with unequal...
JST Seals manufactures spring energized seals of different materials. Spring energized seals are composed of two parts: a PTFE or polymer jacket and a corrosion-resistant, metal energizer spring. comparing to other seals, the seals provide better performance over elastomeric seals and metal gaskets that typically fail. Its sealing jacket is a U-shaped shell made of high-performance non-metallic po...
PolyPak seal is a precision molded multi-purpose seal that combines an o-ring type synthetic rubber o-spring with a traditional lip seal to produce a unique sealing device capable of sealing both vacuum, high and low pressure. Traditional lip seals are prone to leakage at low pressure because the inherent lip load in basic seal design is small or non-existent. However, PolyPak is an extruded seal ...
A water pump seal is a mechanical component that helps to contain the liquid inside a pump and prevent it from leaking. The seal is usually located between the pump's rotating shaft and the pump housing. The purpose of a water pump seal is to provide a barrier between the liquid being pumped and the environment outside the pump, thus preventing leaks and contamination of the liquid. There are seve...
