(Nigeria unidirectional cylinder,produced by Hengyu Group）

unidirectional cylinder are widely used in Nigeria，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed unidirectional cylinder for customers from Nigeria.

Introduction to unidirectional cylinder:

The piston seal of the unidirectional cylinder is the main element to prevent leakage in the unidirectional cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

unidirectional cylinders in series, parallel and series parallel. Series: In the unidirectional cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the unidirectional cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the unidirectional cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the unidirectional cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

unidirectional cylinder buffer valve inspection and maintenance: For the valve buffer unidirectional cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

unidirectional cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the unidirectional cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

Answers to some questions about unidirectional cylinder:

How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.
