The pressure of the high-pressure hose is different according to the working conditions of the customer's application, and different types of hydraulic oil pipes can be selected. The working pressure of the pipeline we usually say refers to the stable and stable pressure when it is working normally. Sometimes there will be pressure fluctuations, so the hydraulic oil pipe also has its test pressure, which is generally more than twice the working pressure. The burst pressure is measured by the pressure test equipment. The pipe body is pressurized in the pressure test equipment until the pipe body bursts, and the instantaneous pressure value reached is generally about 3 times the working pressure of the pipe body. Filler is a key raw material of rubber and can be composed of many materials. There are many kinds on the market today, but they are all varied. In recent years, we have continued to improve the surface technology of inorganic fillers. Through research and practical application, we have produced inorganic fillers with high quality, low price and excellent quality, which has brought technical support for the application of inorganic fillers in the field of rubber hoses, so that the hoses have With magnetic and electrical conductivity, the hose has better processing performance. On May 23, congratulations to the company's technician Wu Bibo for winning the May 1st Labor Award in Luohe City. At the same time, we call on all Litong personnel to take Comrade Wu Bibo as a model, work hard and love each other, drill a good line, and actively practice the team of "letting price to promote global intelligent manufacturing", and make every effort to complete Litong "becoming a global liquid high-tech industry development" To achieve the vision of "the leader", it will be more decisive to build a moderately prosperous society in an all-round way, to create a splendid chapter in the new era, and to make due contributions. In terms of anti-wear properties, the anti-wear properties of rubber hoses are several times higher than those of general ash removal steel wire telescopic hoses, especially suitable for the transportation of some engineering debris, fiber residues, mechanical debris and some particulate matter. , Even if it is subjected to the friction of gravel, gravel and other objects with extremely high flow speed and very frictional force, the hose will not be damaged. The steel wire braided hose is an upgraded product of the wear-resistant rubber hose, which is light in weight, small in diameter and easy to install. It is suitable for various mortar or material transportation environments, and the high-pressure system transports various substances and chemical raw materials. When producing high-pressure wear-resistant hoses, the operating temperature is between -40° and 120°, and the connecting pipe materials with low fluid resistance and imported UPE are selected. , resistant to all-day material. The service life of rubber tubes is a problem that customers are concerned about. In order to increase the service life of oil seals, it is necessary to improve the temperature resistance of plastic materials commonly used for oil seals. After determining the type of rubber, the vulcanization system is the key. For example, it is composed of nitrile rubber, and the application of DCP chloroprene vulcanization system and its addition of vulcanization aids (such as magnesium methacrylate) to improve temperature resistance can effectively improve temperature resistance. Only when the oil seal is in place, the steel wire inside the hose can be well maintained, thereby increasing the life.
