(Estonia unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to unidirectional cylinder:

When the unidirectional cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the unidirectional cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The unidirectional cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

unidirectional cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the unidirectional cylinder head itself is the guide sleeve of the piston rod, the unidirectional cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the unidirectional cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

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

Answers to some questions about unidirectional cylinder:

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.

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.
