(Belarus shearing machine cylinder,produced by Hengyu Hydraulic Co., Ltd）

shearing machine cylinder are widely used in Belarus，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed shearing machine cylinder for customers from Belarus.

Introduction to shearing machine cylinder:

shearing machine cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The shearing machine cylinder should be vented: when the shearing machine cylinder is installed or parked for a long time to work again, the air will penetrate into the shearing machine cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the shearing machine cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the shearing machine cylinder, the oil is best entered and discharged from the highest point of the shearing machine cylinder. shearing machine 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.

Improve the service life of the shearing machine 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 shearing machine cylinder (such as the shearing machine 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 shearing machine 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 shearing machine cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single shearing machine cylinder exhaust.

Do not regularly check the damage of the chrome layer of the shearing machine cylinder: completely extend the shearing machine cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the shearing machine cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the shearing machine cylinder seal. Welding slag is strictly prohibited on the surface of the shearing machine cylinder.

Answers to some questions about shearing machine cylinder:

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.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
