(Switzerland punch machine hydraulic cylinder,produced by Hengyu Group）

punch machine hydraulic cylinder are widely used in Switzerland，because of smooth movement，no need for deceleration device，long service life.So our company has designed punch machine hydraulic cylinder for customers from Switzerland.

Introduction to punch machine hydraulic cylinder:

punch machine hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards punch machine hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the punch machine hydraulic cylinder guide is determined by the length of the stroke. Check the strength of punch machine hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the punch machine hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Do not regularly check the damage of the chrome layer of the punch machine hydraulic cylinder: completely extend the punch machine hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the punch machine hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the punch machine hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the punch machine hydraulic cylinder.

Piston punch machine hydraulic cylinder is widely used in hydraulic transmission. When the punch machine hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the punch machine hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the punch machine hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Answers to some questions about punch machine hydraulic cylinder:

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.

How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
