Because the good price and quality Hydraulic rotary cylinder from China manufacturer  has to bear great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the good price and quality Hydraulic rotary cylinder from China manufacturer is the most important part of the maintenance of the whole hydraulic system.

The good price and quality Hydraulic rotary cylinder from China manufacturer  is equivalent to the heart of the hydraulic system. It is difficult to repair the heart problem, so the maintenance of the hydraulic rotary cylinder should be careful.

First, rust prevention. Because the piston part of the hydraulic rotary cylinder extends out of the cylinder in the working state, it will naturally be eroded by oxide and acid gas, which requires us to coat it with an appropriate amount of grease for protection, so as to prevent the piston as a load-bearing component from being eroded and broken in work.

Secondly, open the box and change the oil. Because of long-term use, it is inevitable that foreign matters will enter the hydraulic cylinder, so that the friction will increase in use. In addition, the hydraulic rotary cylinder also has a certain service life, and long-term non oil change will damage or erode the inside of the hydraulic cylinder.

Prevention is better than cure. Therefore, in the operation of the hydraulic rotary cylinder, the speed should be controlled appropriately, not more than 2m / s, which can prolong the service life of the hydraulic rotary cylinder. In addition, in order to protect the body structure and safety, the internal buffer device is ten times effective for the protection of the hydraulic rotary cylinder.

When oil leakage occurs, disassemble the oil cylinder, clean and replace with a new oil seal and seal. Care must be taken in the whole process, because some parts are made of aluminum alloy and need to avoid scratch and damage.

The following measures can be taken for the maintenance of good price and quality Hydraulic rotary cylinder from China manufacturer in use:

1. Clean the oil suction filter screen once every 2 ~ 3 months.

2. Check the hydraulic rotary cylinder once every half a year. If it has deteriorated, please replace it.

3. When operating the machine tool with the maximum oil pressure and maximum speed, disassemble and inspect the internal parts every year, and replace the oil seal and seal.

4. When the instantaneous sudden pressure is too high, it will cause abnormal operation and damage of the hydraulic rotary cylinder, so the pressure reducing valve must be adjusted to reduce the transient pressure.

5. For hydraulic rotary cylinder with pressure maintaining function, check whether the function of check valve is normal after power failure every week. The inspection method is: first let the chuck hold a round rod, and then turn off the power supply to check whether the workpiece is reliably clamped and whether it is still in the original clamping position. If it is inappropriate, it must be sent to the manufacturer for maintenance immediately.

Possible causes and inspection methods of non actuation of good price and quality Hydraulic rotary cylinder from China manufacturer :

1. Stop the refueling system. Check whether the oil pressure system operates normally.

2. Pipeline connection error. Confirm that all pipelines are connected correctly.

3. The direction of the hydraulic station is wrong. Correct again according to the test steps during the operation of the hydraulic rotary cylinder.

Possible causes and inspection methods of insufficient driving force of hydraulic rotary cylinder:

1. The pressure is not at normal value. A pressure gauge is installed to test at the oil inlet of the hydraulic rotary cylinder.

2. The pressure of the oil return pipe is too high or the oil discharge is more than the normal value. Check whether the O-ring is damaged and whether it needs to be replaced.

3. The filter screen at the oil suction port is blocked. Clean the impurities in the filter screen and oil tank and replace the hydraulic oil.
