China Xingtai Chengzhi Seals Co., Ltd. Company News

During the exhibition, Indonesian customers came to the booth to help. The booth attracted countless visitors, and we have been communicating with exhibitors with full enthusiasm and serious attitude. After a certain understanding, the exhibitors at the exhibition gave high recognition and evaluation to the products and showed certain cooperation intentions. Making high-quality products has always been our goal.                                    

  Thank you for your participation in INDONESIA ENERGY & ENGINEERING SERIES 2024.   Our booth number: D2-9416   We will bring oil seals, O-rings, bonded seals of various models and sizes   we look forward to seeing you at INDONESIA ENERGY & ENGINEERING SERIES 2024.  

During use, it is permissible if a small amount of leakage occurs within 50 to 100 hours of the initial operation. As the operating time increases, the leakage will gradually stop, and the life of such oil seals is often relatively long. Within the effective period of use, a small amount of leakage is allowed, otherwise, it must be dealt with in accordance with the following common failure causes and troubleshooting methods of oil seals. 1. The skeleton oil seal is not good, causing early leakage 2. Poor assembly, leakage occurs 3. Lip wear 4. The oil seal has poor compatibility with the working medium, and the lips are soft, swollen or hardened, and cracked 5. Rubber aging 6. Axis

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. 1. Prevent sediment, dust, moisture, etc. from intruding into the bearing from the outside; 2. Limit the leakage of lubricating oil in the bearing. The requirements for the oil seal are that the dimensions (inner diameter, outer diameter and thickness) should meet the regulations; appropriate elasticity is required, which can properly clamp the shaft and play a sealing role; it must be heat-resistant, wear-resistant, strong, and resistant to media ( oil or water, etc.), long service life. In order to use the oil seal reasonably, the following points should be paid attention to: (1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts should use low-speed oil seals, and low-speed oil seals cannot be used on high-speed shafts, and vice versa. (2) When the ambient temperature is high, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be selected. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used. (3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. Under the condition of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used. (4) The degree of eccentricity on the installation When the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a "W"-shaped oil seal can be used. (5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal. (6) Note that there should be a certain amount of lubricating oil on the lip of the oil seal. (7) Pay special attention to prevent dust from immersing in the oil seal.

Introduction to skeleton oil seal Skeleton oil seal is a typical representative of oil seal. Generally speaking, oil seal refers to skeleton oil seal. The function of the oil seal is generally to isolate the parts of the transmission components that need lubrication from the external environment to prevent lubricating oil from leaking. The skeleton is like a steel bar in a concrete member, acting as a reinforcing bar that allows the oil seal to maintain its shape and tension. According to the structure, it can be divided into single lip skeleton oil seal and double lip skeleton oil seal. The auxiliary lip of the double-lip skeleton oil seal acts as a dust-proof function to prevent external dust and impurities from entering the machine. According to the skeleton type, it can be divided into internal skeleton oil seal, exposed skeleton oil seal and assembled oil seal. According to the working conditions, it can be divided into rotating skeleton oil seal and reciprocating skeleton oil seal. Suitable for gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other components.   Skeleton oil seal is a typical representative of oil seal.
