Mini Telescopic Hydraulic Cylinder

The telescopic hydraulic cylinder is a hydraulic cylinder with a multistage sleeve piston rod that can obtain a long working stroke. The telescopic hydraulic cylinder is also called a multistage hydraulic cylinder. The telescopic hydraulic cylinder is composed of two or more piston hydraulic cylinders. The piston rod of the previous piston cylinder is the cylinder barrel of the next piston cylinder.

Misoperation or fault

The causes and handling methods are as follows:

(1) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, the hydraulic cylinder does not act or almost does not act regardless of operation. At this time, we should check whether the piston and piston rod seals are too tight, whether dirt and colloidal deposits enter into them: whether the piston rod and cylinder axes are correct, whether the worn parts and seals fail, and whether the load is too large.

(2) The spool valve is stuck or the valve hole is blocked. At this time, check the wear of the valve body, clean and replace the system filter, and check the oil pollution; Check whether there are dirt or colloidal deposits on the valve core or plug the valve hole; Clean the oil tank and replace the hydraulic medium.

All parameters can be customized

Parameters of the sample

When the pressure oil enters through the rodless chamber, the cylinder with the largest effective area of the piston begins to extend, and when it reaches the end, the cylinder with the next largest effective area of the piston begins to extend. The extension sequence of the telescopic hydraulic pressure is extended from large to small, which can obtain a very long working stroke. The smaller the effective area of the extension cylinder, the faster the extension speed. Therefore, the extension speed is slow and fast, and the corresponding hydraulic thrust decreases from large to small; This change law of thrust and speed is suitable for the requirements of various automatic loading and unloading machinery on thrust and speed. The retraction sequence is generally from small to large, and the axial length of retraction is short, occupying less space, and the structure is compact. It is often used in the hydraulic system of construction machinery and other walking machinery, such as crane, tipper car, etc.

HCIC has taken the lead in passing ISO9001, CE and other international quality system certification in the same industry, and has been awarded the honorary titles of "Star Enterprise of Scientific and Technological Innovation" and "Forerunner of Foreign Trade" for many times.
