push plate cylinder Sold to New Zealand

This article mainly introduces:

New Zealand hydraulic cylinder,push plate cylinder manufacturer,push plate cylinder

(New Zealand push plate cylinder,produced by Hebei Hengyu company）

push plate cylinder are widely used in New Zealand，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed push plate cylinder for customers from New Zealand.

Introduction to push plate cylinder:

The push plate cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the push plate cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The push plate cylinder is basically composed of push plate cylinder and push plate cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Before the push plate cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

Disassembly push plate cylinder: When disassembly push plate cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the push plate cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the push plate cylinder.

The wear of the hard chromium plating layer of the push plate cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Answers to some questions about push plate cylinder:

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
