Paraguay hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder

(Paraguay steel mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

steel mill cylinder are widely used in Paraguay，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed steel mill cylinder for customers from Paraguay.

Introduction to steel mill cylinder:

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

Improve the service life of the steel mill cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the steel mill cylinder (such as the steel mill cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the steel mill cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the steel mill cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single steel mill cylinder exhaust.

Under normal circumstances, the steel mill cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the steel mill cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the steel mill cylinder and the end cover, the piston and the piston rod, the piston and the steel mill cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the steel mill cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

steel mill cylinder can not drive the load troubleshooting: oil pressure is too low. steel mill cylinder selection specifications are too small. Leakage in steel mill cylinder or associated hydraulic system element.

Answers to some questions about steel mill cylinder:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.
