(America stern plate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

stern plate hydraulic cylinder are widely used in America，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stern plate hydraulic cylinder for customers from America.

Introduction to stern plate hydraulic cylinder:

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

The stern plate hydraulic cylinder is not the same as the stern plate hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the stern plate hydraulic cylinder can not be used as a high-power power component, but the stern plate hydraulic cylinder can be used as a relatively large power component, or the stern plate hydraulic cylinder system can be used.

When installing the stern plate hydraulic cylinder, the axial ends of the stern plate hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stern plate hydraulic cylinder, there is axial expansion. If the two ends of the stern plate hydraulic cylinder are fixed, all parts of the stern plate hydraulic cylinder will be deformed. When disassembling the stern plate hydraulic cylinder, it is strictly forbidden to hammer the stern plate hydraulic cylinder and the piston surface, such as the stern plate hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

In order to ensure the service life of the stern plate hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about stern plate hydraulic cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.
