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

trailer hydraulic cylinder are widely used in Colombia，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 Colombia.

Introduction to trailer hydraulic cylinder:

trailer hydraulic cylinder use should try to avoid sealing belt into the trailer hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the trailer hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the trailer hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

At the rated pressure, the thrust of the trailer hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the trailer hydraulic cylinder is related to the diameter of the trailer hydraulic cylinder, but not to the stroke of the trailer hydraulic cylinder. Moreover, the larger the trailer hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the trailer hydraulic cylinder.

Causes and countermeasures of oil trailer hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the trailer hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the trailer hydraulic cylinder is visibly scarred, the trailer hydraulic cylinder must be replaced. It can be pressurized at one end of the trailer hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most trailer hydraulic cylinder piston drift may not come from the trailer hydraulic cylinder, the above method to determine the trailer hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

If the piston rod and trailer hydraulic cylinder are stuck or the trailer hydraulic cylinder is blocked, at this time, no matter how to operate, the trailer hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the trailer hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about trailer hydraulic cylinder:

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
