(Puerto Rico punch machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to punch machine hydraulic cylinder:

After the punch machine hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

When installing the punch machine hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the punch machine hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the punch machine hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the punch machine hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the punch machine hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

When the punch machine hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the punch machine hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

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

Answers to some questions about punch machine hydraulic cylinder:

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.

Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.
