Bulgaria hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder
(Bulgaria self-locking hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
self-locking hydraulic cylinder are widely used in Bulgaria，because of smooth movement，clever hydraulic energy conversion，powerful torque.So our company has designed self-locking hydraulic cylinder for customers from Bulgaria.
self-locking hydraulic cylinder body inspection: The inner surface of the self-locking hydraulic cylinder and the piston seal are the main factors causing the leakage in the self-locking hydraulic cylinder, if the self-locking hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the self-locking hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.
When using the self-locking hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the self-locking hydraulic cylinder block. If the self-locking hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the self-locking hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the self-locking hydraulic cylinder, so that the working efficiency of the self-locking hydraulic cylinder is reduced.
Most of the failure of the self-locking hydraulic cylinder is because there is a foreign body in the self-locking hydraulic cylinder into the failure of the self-locking hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the self-locking hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
The meaning of the self-locking hydraulic cylinder model marked by the self-locking hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the self-locking hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the self-locking hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
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.
