(Spain vehicle hydraulic cylinder,produced by Hebei Hengyu company）

vehicle hydraulic cylinder are widely used in Spain，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed vehicle hydraulic cylinder for customers from Spain.

Introduction to vehicle hydraulic cylinder:

When the initial action of the vehicle 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 vehicle 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.

If the vehicle hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

The difference between the plunger vehicle hydraulic cylinder and the piston vehicle hydraulic cylinder is that the piston in the vehicle hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type vehicle hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When the vehicle hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the vehicle hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Answers to some questions about vehicle hydraulic cylinder:

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
