(forklift lift cylinder,produced by Hengyu Hydraulic Co., Ltd)

forklift lift cylinder are widely used ,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed forklift lift cylinder for our customers.

Introduction to forklift lift cylinder:

If the forklift lift 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 forklift lift cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow forklift lift cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the forklift lift cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the forklift lift cylinder includes the leakage caused by excessive wear of the forklift lift 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 forklift lift cylinder, and the phenomenon of "pulling the forklift lift cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The forklift lift cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

forklift lift cylinder buffer valve inspection and maintenance: For the valve buffer forklift lift cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

forklift lift cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the forklift lift cylinder head itself is the guide sleeve of the piston rod, the forklift lift 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 forklift lift cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Answers to some questions about forklift lift cylinder:

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.
