(Belgium unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Belgium，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed unidirectional cylinder for customers from Belgium.

Introduction to unidirectional cylinder:

unidirectional cylinder piston rod material introduction: In general, we use 45 steel to produce unidirectional 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.

When the unidirectional cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the unidirectional cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

unidirectional cylinder and hydraulic station selection: Select the type and structure of the unidirectional cylinder according to the operation requirements of the main engine. According to the external load force borne by the unidirectional cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the unidirectional cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the unidirectional cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the unidirectional cylinder, the diameter of the piston and the piston rod.

When the unidirectional cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about unidirectional cylinder:

The two cylinders of the bending machine are out of sync?
Check whether the sliding slide is worn, adjust its tightness, so that both sides are consistent, check whether the two cylinder tubing is connected, tighten the flow valve, pressure, let the cylinder air discharge.

What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
