(Costa Rica boarding axle cylinder,produced by Hengyu Group）

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

Introduction to boarding axle cylinder:

The commonly used buffer structure of the boarding axle cylinder is composed of a piston boss and a boarding axle cylinder head groove. When the piston moves close to the boarding axle cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

When the boarding axle cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the boarding axle cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

When the boarding axle cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the boarding axle cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

The boarding axle cylinder is mainly composed of body, piston, piston rod, boarding axle cylinder head, boarding axle cylinder bottom, piston rod head and related auxiliary devices. The piston divides the boarding axle cylinder into two chambers, and moves reciprocally in the boarding axle cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the boarding axle cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the boarding axle cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the boarding axle cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the boarding axle cylinder bottom and the boarding axle cylinder head is serious, so the buffer deceleration should be set at both ends of the boarding axle cylinder The working medium of the boarding axle cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; boarding axle cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the boarding axle cylinder: The buffer structure of the boarding axle cylinder is to prevent the piston from colliding with the boarding axle cylinder head at the end of the stroke.

Answers to some questions about boarding axle cylinder:

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.
