Vietnam jack cylinder

(Vietnam jack cylinder,produced by Hengyu Group)

jack cylinder are widely used in Vietnam,because of smooth movement,no need for deceleration device,long service life.So our company has designed jack cylinder for customers from Vietnam.

Introduction to jack cylinder:

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

After chrome plating of the piston rod of the jack cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

When purchasing the jack cylinder, try to clarify the following parameters of the jack cylinder: A. jack cylinder diameter, rod diameter, stroke; B. Working pressure or jack cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right jack cylinder type can be found accurately and quickly.

The scar on the sliding surface of the jack cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the jack cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about jack cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
