Republic of Lithuania hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Republic of Lithuania tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
tailplate hydraulic cylinder are widely used in Republic of Lithuania,because of clever hydraulic energy conversion,clever hydraulic energy conversion,high work efficiency.So our company has designed tailplate hydraulic cylinder for customers from Republic of Lithuania.
Protection of the tailplate hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the tailplate hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the tailplate hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the tailplate hydraulic cylinder should be cleaned up in time.
When the control pressure of the hydraulic system is too low, the tailplate hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
The piston rod of the tailplate hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
If the tailplate hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the tailplate hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow tailplate hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the tailplate hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the tailplate hydraulic cylinder includes the leakage caused by excessive wear of the tailplate hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and tailplate hydraulic cylinder, and the phenomenon of "pulling the tailplate hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
