Automotive air-conditioning compressor O-ring?
Automotive air conditioning O-rings be useful, where is it available? xinhuaxu Rubber Products Company O-ring professional manufacturers tell you to use the case automotive air conditioning compressor at the O-ring. [View Details]
Application of the rubber valve seals?
Ball knows what is it? A ball is under different environmental conditions, can be manually driven, pneumatic or electric drive means driving means to achieve the opening and closing of the valve. As a rubber ring sealing element, which static sealing and dynamic sealing play an important role in various types of ball valves in sealing performance. . Rubber seal on the end face of the valve stem and can effectively prevent the leakage of all types of media, to ensure the normal operation of the valve system. Rubber seal is mounted on both ends of the surface of it belongs to the static sealing effect, is mounted on the valve body and valve stem hole genus dynamic sealing effect. Two types of sealing effect fully meet the design requirements of the ball. [View Details]
To pay attention to the detection of hydraulic seals !!
China's rubber parts manufacturing plant, although many, but not a professional factory specializing in the production of hydraulic hydraulic seals, at present, is supporting the production of hydraulic seal hydraulic seal most factories obsolete equipment, industrial backwardness, incomplete testing methods, product quality is difficult to be guaranteed .Existing hydraulic seal failure in use, about 30% were caused by failure of hydraulic seals.The main reason is the hydraulic seal of quality testing, it has not attracted attention.

How to pick the right rubber O-ring
Rubber O-ring seal is a typical extrusion, so resilience and resistance to permanent deformation of the product's performance is to determine whether the rubber O-ring is the main quality standard, rubber O-ring seals in many combinations which acts as a pressure seal and the role of preload. If there is no good resilience will greatly reduce the sealing performance. Since the rubber O-ring seals for both to do and to do static seals, and can also be used with other sealing devices in combination, so the application is very extensive. [View Details]
Frictional heat can cause damage to the O-ring it?
Increase friction, making the rotating or reciprocating shaft and hydraulic O-ring between a large amount of frictional heat. Since the majority of the hydraulic O-rings are made of rubber, poor thermal conductivity. Therefore, the friction heat can cause aging of the rubber, resulting in a hydraulic O-ring effectiveness and undermine its sealing performance. Hydraulic friction can also cause surface damage O-ring, so that the amount of compression is reduced. Will soon lead to serious friction surface damage hydraulic O-ring, lost tightness. Pneumatic seal for reciprocating motion, the friction heat can also cause adhesion, resulting in a further increase friction, resulting in deformation of the O-ring. [View Details]
How true selection hydraulic seals?
Hydraulic pressure sealing requirements, it requires a certain combination of surface finish, use of rubber sealing element, to achieve the blocking effect by local deformation of the sealing member. [View Details]
Seals automotive air conditioning refrigerant pipe duct
Sealed refrigeration pipes is the basis of car air conditioning systems work properly, threaded pipe joints refrigeration automobile air conditioning O-ring locking pipe joints sealed manner in the automotive car air conditioning systems most widely used pipe joint, follow the installation directions are divided into different axial automotive air conditioning O-ring seals and meridional automotive air conditioning O-ring seal, threaded locking connectors seal nut tightening torque is very sensitive. Once a screw loose connections will cause leaking pipeline system, affect the reliability of automotive air conditioning and refrigeration systems. [View Details]

Automotive air conditioning O-rings Installation
Automotive air conditioning O-ring is an extruded-ring, rear air conditioning O-ring into the groove, generally have a certain amount of stretch, sealing parts and installation of automotive air conditioning O-rings must pass the site, must be smooth loss less, regular shape, in order to prevent damage tothe installation, import, etc. in the sealing groove design should be ass tandard chamfer, rounded. When maintenance to keep clean automotive air conditioning O-ring mounting groove, do not damage mounting groove cleaning. [View Details]
