A monitoring switch (Monitoring Switch) is an instrument that turns on or off an electrical contact point by means of a detection instrument, and is used for, for example, detection of liquid level, pressure, temperature, and flow rate.

Pressure indicator (Pressure Indicator) indicates pressure indicating device.

Flow indicator indicating device for indicating flow

Function indicator (Function Indicator) is an indicator device that mechanically indicates the function of the element, such as the indicator rod of the dispenser

Liquid level indicator or liquid level indicator indicates the level of lubricating oil, such as oil window, detection rod (electrical level indicator), moving piston with guide bar, etc.

Lubricating Cycle Counter (Lubricating Cycle Counter) counts the number of lubrications and makes a digital display indicator

Oil Cooler or Oil Heat Exchanger is a device that heats and cools lubricating oil to maintain its normal temperature

Leakage Leakage refers to the phenomenon of a small amount of fluid that does not do useful work and leaks from the seal of the moving pair.

Seals (Seals) are used to prevent the leakage of fluid or solid particles from the adjacent bonding surfaces and the intrusion of external impurities such as dust, sediment, moisture, etc.

Static Seal (Static Seal) Seal with static surface

Dynamic seal (Dynamic Seal) The seal where relative motion occurs on the joint surface

Exclusion Seal (Exclusion Seal) A seal that produces a sealing effect by the contact pressure generated by the compression of the seal ring, such as an "O" type seal ring.

The Lip Seal has a flexible lip, a seal that prevents leakage by the radial force applied by the sealing blade, also known as a "cup"

Rotary Shaft Lip Seal (Rotary Shaft Lip Seal) is a lip seal used for rotary seals, also known as "oil seal"

Reciprocating Seal (Reciprocating Seal) A lip seal for reciprocating parts such as cylinders or cylinders

Hydrodynamic Aided Rotary Shaft Lip Seal (Hydrodynamic Aided Rotary Shaft Lip Seal) The rear surface of the sealing lip has a certain pattern, which can change the contact state of the sealing lip and the shaft, and return the fluid leaking through the lip to the sealed Seal in the cavity

Gasket for sheet seal between two stationary surfaces

Printed Gasket (Printed Gasket) is a kind of sealing gasket produced by printing process on a substrate.

Coaxial seal (Co-axial Seal) A composite seal in which a plastic ring and a rubber ring are sleeved together and all or most of them are made of a plastic ring as a friction sealing surface.

Mechanical seal or face seal is composed of at least a pair of end faces perpendicular to the axis of rotation to prevent fluid leakage by maintaining fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the auxiliary seal to maintain adhesion and relative sliding. Device.

Clearance Seal A seal that limits leakage by the effect of fluid resistance in the sealed gap.

Labyrinth Seal (Labyrinth Seal) A seal that allows fluid to pass through a tortuous gap channel and flow resistance caused by multiple throttling to limit leakage.

Ferromagnetic Seal (Ferromagnetic Seal) uses magnets and polar plates to generate a series of high-level (strength) magnetic fields, collecting ferrofluid in the annular gap (or end gap) around the shaft in the sealed box, forming a liquid ring blockage Sealing device for working fluid.

Adhesive sealant (Adhesive Sealant) is used to seal between static joints. Before coating, it is a liquid viscous substance with fluidity, easy to fill the gap between the two joint surfaces, and plays a good sealing role. Including liquid sealant, anaerobic sealant, silicone sealant, etc.

Lubricant is a substance added between two relatively moving surfaces to reduce friction and wear.

Lubricating Oil (Lubricating Oil) is mainly used to reduce the friction between relatively moving surfaces of refined oil products.

Base Oil is used to produce refined oils for lubricants and other products. This base oil can be used alone or blended with other oils or additives.

Synthetic Lubricant (Synthetic Lubricant) Lubricant made by chemical methods.

Grease A stable solid or semi-solid product composed of thickener dispersed in a liquid lubricant. This product can incorporate additives and fillers designed to improve certain properties.

Additive (Additive) can add some special properties to the oil or enhance its inherent properties.

Inhibiter (Inhibiter) can prevent or delay the occurrence of adverse phenomena in petroleum products (such as the formation of stored gasoline gums, lubricating oil discoloration, etc.).

Mineral oil (Mineral Oil) naturally occurring, or obtained from the treatment of other mineral raw materials, mainly composed of a mixture of various hydrocarbons.
