QYd shaft sealing ring

QY series sealing ring is the most commonly used sealing ring in oil cylinder, it is a typical lip sealing ring. In the case of low pressure, the seal is only produced by the interference deformation of the lip, and the friction force is relatively low due to the small contact surface. As the pressure increases, the elastic deformation of the lip increases, the tensile, compressive and bending stresses increase, the radial compression force of the sealing ring automatically increases, and the length of contact with the sealing surface continues to increase until the entire axial length of the sealing ring Contact with the sealing surface to ensure good sealing under high pressure

EU sealing ring

The EU-type piston rod dust-proof sealing ring for the cylinder is formed by a single part, and its main functions are sealing, dust-proof and fixing.

Iron shell oil seal

The TB iron shell oil seal is the exposed skeleton oil seal. Compared with the inner skeleton oil seal, the iron shell oil seal has the characteristics of good rigidity, easy installation, safe use, accurate positioning, high coaxiality, good heat conduction and heat dissipation, and saving glue. The outer skeleton oil seal is the centerless grinding of the skeleton of the oil seal to improve the coaxiality of the outer wheel and the inner wheel after the oil seal is assembled, thereby improving the dynamic sealing accuracy of the skeleton oil seal and better preventing oil leakage. The outer frame oil seal requires higher installation machining accuracy. Rubber and plastic material: nitrile rubber (letters represent NBR) heat-resistant 120 degrees, good oil resistance, EPDM rubber (letters represent EPDM) heat-resistant 150 degrees, not oil-resistant silicone material (letters represent VMQ) heat-resistant 220 degrees oil-resistant general poly4 Fluoroethylene (letters represent PTFE), heat-resistant 280 degrees, good oil resistance, fluorine rubber (letters represent FKM), heat-resistant 200 degrees, good oil resistance, polyurethane (letters represent PU), heat-resistant and 90 degrees wear-resistant.

Stainless Steel Shell Oil Seal

The function of the skeleton oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. According to the skeleton type, it can be divided into inner skeleton oil seal, outer skeleton oil seal, and inner and outer skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life. Widely used in automobiles, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels and other parts.

Fan Sefeng

Spring Seal/ spring energized seal/ Variseal is a U-shaped Teflon high-performance seal with a special spring inside. By the appropriate spring force plus the system fluid pressure, the sealing lip (surface) is pushed out. Gently press down on the metal surface being sealed to create a very good seal. The actuation effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, while maintaining the expected sealing performance.

PTFE gasket

PTFE gaskets are also called PTFE gaskets or Teflon (Teflon) gaskets abroad. Flat gaskets, V-shaped gaskets, piston rings are machined or cut from PTFE rods, tubes, and plates. , ball valve gaskets, etc. have good characteristics such as corrosion resistance, aging resistance and non-conductivity. PTFE pH 0-14 (except molten alkali metals and fluorine at high temperature and high pressure). It can have good mechanical strength between -100°C and 100°C. Use pressure 10Mpa. At temperatures below -185°C, PTFE gaskets become brittle. Pure PTFE gaskets are a clean sealing product that will not contaminate anything they come in contact with.

The metal strips are fixed by spot welding at the beginning and end. Metal spiral wound gasket is the gasket with the best resilience among semi-metal gaskets

anise pad

The octagonal metal ring gasket is installed in the trapezoidal ring groove on the flange surface. When the connecting bolt is tightened, it is axially compressed and tightly attached to the upper and lower trapezoidal grooves, resulting in plastic deformation, forming an annular sealing band and establishing the initial seal. After boosting, under the action of medium pressure, the ring gasket is radially expanded. The gasket and the inclined surface of the trapezoidal groove are more tightly fitted, resulting in a self-tightening effect. However, the increase of the medium pressure will also deform the flange and the connecting bolt, resulting in the relative separation between the sealing surfaces and the relative decrease in the gasket sealing ratio. Therefore, the ring gasket can be considered as a semi-self-tightening seal. The octagonal metal ring gasket is mainly in surface contact with the flange groove. Compared with the oval ring gasket, although it is not easy to achieve close contact with the flange groove, it can be used again and is easy to process because the cross section is composed of straight lines. At the same time, the hardness of the octagonal metal ring gasket should be 15~20HB lower than the flange surface.

NBR nitrile rubber gasket

Nitrile-butadiene rubber is a synthetic rubber suitable for good corrosion resistance to oils, solvents, aromatic hydrocarbons, basic hydrocarbons, oil and natural gas over a wide temperature range. Good corrosion resistance to hydroxides, salts and near neutral acids. However, in strong oxidizing media, chlorinated hydrocarbons, ketones and lipids, its corrosion resistance is poor, and the recommended working temperature is 51℃~121℃.

FKM fluoro rubber gasket

Fluoroelastomer has a high degree of chemical stability and is one of the medium-resistant properties of all elastomers at present. Type 26 fluororubber is resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic and inorganic solvents, pharmaceuticals, etc., only low molecular weight ketones, ethers, Ester, not resistant to amine, ammonia, hydrofluoric acid phosphoric acid hydraulic oil. The dielectric properties of type 23 fluorine rubber are similar to those of type 26, and it is more unique. Its resistance to strong oxidizing inorganic acids such as fuming nitric acid and concentrated sulfuric acid is better than that of type 26. It is immersed in 98% HNO3 at room temperature. Its volume expansion is only 13% to 15%.
