hydraulic press cylinder are widely used in Colombia，because of long service life，smooth movement，high work efficiency.So our company has designed hydraulic press cylinder for customers from Colombia.

Introduction to hydraulic press cylinder:

When purchasing the hydraulic press cylinder, try to clarify the following parameters of the hydraulic press cylinder: A. hydraulic press cylinder diameter, rod diameter, stroke; B. Working pressure or hydraulic press cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right hydraulic press cylinder type can be found accurately and quickly.

When the piston speed of the hydraulic press cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the hydraulic press cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

When the hydraulic press cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the hydraulic press cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the hydraulic press cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Under normal circumstances, the hydraulic press cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the hydraulic press cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the hydraulic press cylinder and the end cover, the piston and the piston rod, the piston and the hydraulic press cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the hydraulic press cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about hydraulic press cylinder:

Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.

What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!
