Ethiopia punch machine hydraulic cylinder

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

punch machine hydraulic cylinder are widely used in Ethiopia,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed punch machine hydraulic cylinder for customers from Ethiopia.

Introduction to punch machine hydraulic cylinder:

punch machine hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the punch machine hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the punch machine hydraulic cylinder. c. The punch machine hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the punch machine hydraulic cylinder seal, replace the punch machine hydraulic cylinder seal.

If air enters the hydraulic system, the punch machine 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 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.

The punch machine hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure punch machine hydraulic cylinder can use 20 steel pipe, and the high pressure punch machine hydraulic cylinder can use 45 steel pipe.

Answers to some questions about punch machine hydraulic cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
