(Bulgaria trailer hydraulic cylinder,produced by Hebei Hengyu company）

trailer hydraulic cylinder are widely used in Bulgaria，because of no need for deceleration device，high work efficiency，excellent fatigue and impact resistance.So our company has designed trailer hydraulic cylinder for customers from Bulgaria.

Introduction to trailer hydraulic cylinder:

The internal leakage of the trailer hydraulic cylinder should be prevented when the trailer hydraulic cylinder is used. The internal leakage of trailer hydraulic cylinder includes the leakage caused by excessive wear of trailer hydraulic cylinder block seal, piston rod and seal cover seal and 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.

If air enters the hydraulic system, the trailer hydraulic cylinder will not operate normally, 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.

The definition of the minimum stable speed refers to the minimum movement speed of the trailer hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the trailer hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

trailer hydraulic cylinder piston rod material introduction: In general, we use 45 steel to produce trailer hydraulic cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

Answers to some questions about trailer hydraulic cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
