Dominica hydraulic cylinder,pushing cylinder manufacturer,pushing cylinder

(Dominica pushing cylinder,produced by Hebei Hengyu company）

pushing cylinder are widely used in Dominica，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pushing cylinder for customers from Dominica.

Introduction to pushing cylinder:

Before purchasing the pushing cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

The pushing cylinder should be vented: when the pushing cylinder is installed or parked for a long time to work again, the air will penetrate into the pushing cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the pushing cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the pushing cylinder, the oil is best entered and discharged from the highest point of the pushing cylinder. pushing cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

If the seal of the pushing 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 pushing cylinder, and the phenomenon of "pulling the pushing 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 difference between the integral pushing cylinder and the split pushing cylinder: The integral pushing cylinder and the split pushing cylinder in the pushing cylinder are two different pushing cylinders, and they are very different. The whole pushing cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split pushing cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and pushing cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about pushing cylinder:

Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.
