(Belarus electric forklift hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
electric forklift hydraulic cylinder are widely used in Belarus，because of long service life，smooth movement，high work efficiency.So our company has designed electric forklift hydraulic cylinder for customers from Belarus.
The electric forklift hydraulic cylinder is not the same as the electric forklift hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the electric forklift hydraulic cylinder can not be used as a high-power power component, but the electric forklift hydraulic cylinder can be used as a relatively large power component, or the electric forklift hydraulic cylinder system can be used.
If the electric forklift 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 electric forklift hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow electric forklift hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the electric forklift hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the electric forklift hydraulic cylinder includes the leakage caused by excessive wear of the electric forklift 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 electric forklift hydraulic cylinder, and the phenomenon of "pulling the electric forklift 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.
electric forklift hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the electric forklift hydraulic cylinder head itself is the guide sleeve of the piston rod, the electric forklift hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the electric forklift hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
How to determine the working pressure of the electric forklift hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, electric forklift hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.
Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).
How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
