Turkmenistan hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder(Turkmenistan self-locking hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
self-locking hydraulic cylinder are widely used in Turkmenistan,because of no need for deceleration device,long service life,smooth movement.So our company has designed self-locking hydraulic cylinder for customers from Turkmenistan.
The definition of the minimum starting pressure of the self-locking hydraulic cylinder refers to the minimum working pressure of the self-locking hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the self-locking hydraulic cylinder parts and the size of the sealing friction.
When the initial action of the self-locking hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the self-locking hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
When the hydraulic oil is not pumped into the self-locking hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the self-locking hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
The assembly work of the self-locking hydraulic cylinder has a great impact on the quality of the self-locking hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.
What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
