Poland hydraulic cylinder,steering cylinder manufacturer,steering cylinder(Poland steering cylinder,produced by Hebei Hengyu company)
steering cylinder are widely used in Poland,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed steering cylinder for customers from Poland.
In order to ensure the service life of the steering cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the steering cylinder, causing damage to the seal and causing leakage in the steering cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.
When the steering cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the steering cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil steering cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical steering cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the steering cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
Do not regularly check the damage of the chrome layer of the steering cylinder: completely extend the steering cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the steering cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the steering cylinder seal. Welding slag is strictly prohibited on the surface of the steering cylinder.
The method of sleeve steering cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the steering cylinder can be significantly improved by rolling in the finishing of the inner holes of the steering cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.
