Croatia retractable cylinder

(Croatia retractable cylinder,produced by Hebei Hengyu company)

retractable cylinder are widely used in Croatia,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed retractable cylinder for customers from Croatia.

Introduction to retractable cylinder:

The internal leakage of the retractable cylinder is an important indicator to measure the quality of the retractable cylinder: the internal leakage of the retractable cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the retractable cylinder, so that the retractable cylinder can not accurately and stably stop in a certain position of the retractable cylinder, so it is one of the main indicators of the retractable cylinder.

How the cavitation of the retractable cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the retractable cylinder, resulting in corrosive damage to the parts.

If the seal of the retractable cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and retractable cylinder, and the phenomenon of "pulling the retractable cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

The quality of the retractable cylinder can not be ignored in the purchase of the retractable cylinder. The retractable cylinder is the main component of the retractable cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. retractable cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of retractable cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about retractable cylinder:

How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
