Kazakhstan hydraulic cylinder,lift hydraulic cylinder manufacturer,lift hydraulic cylinder(Kazakhstan lift hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
lift hydraulic cylinder are widely used in Kazakhstan,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed lift hydraulic cylinder for customers from Kazakhstan.
When the lift hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the lift hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the lift hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
After chrome plating of the piston rod of the lift hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
Do not enter foreign bodies when installing the lift hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
The meaning of the lift hydraulic cylinder model marked by the lift hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the lift hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the lift hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.
What are the requirements for hydraulic cylinder assembly? ① The installation of the cylinder should be solid and reliable. In order to prevent the influence of thermal expansion, in the case of large stroke and hot working conditions, one end of the cylinder must be kept floating.② pipe connection shall not be relaxed.③ The mounting surface of the hydraulic cylinder and the sliding surface of the piston rod should maintain sufficient parallelism and perpendicality.④ The central axis of the moving cylinder should be concentric with the center line of the load force, otherwise it will cause lateral force, which is easy to wear the seal And piston damage. The greater the distance between the supporting points of the piston rod, the smaller its wear. For the hydraulic cylinder of the moving object, the installation should keep the cylinder parallel with the moving object, and the degree of non-parallelism is generally not greater than 0.05mm/m. ⑤The sealing ring should not be installed too tightly, especially the U-shaped sealing ring.
