Due to the excellent performance of the hydraulic cylinder, high-quality stability, cost-effective, high mechanical efficiency characteristics are widely used in the hydraulic industry, but the hydraulic cylinder needs to bear a lot of pressure in the work, the more the load, the greater the pressure, so the correct maintenance measures are very necessary, can effectively avoid the damage of the hydraulic cylinder, extend the service life, improve the work efficiency. Will explain to you what are the daily maintenance measures of hydraulic cylinder?
First, the daily maintenance measures of hydraulic cylinder
1. Check preventive measures
(1) The hydraulic cylinder needs to be fully telescoped for five strokes during each use to run with load, exhaust the air in the system, preheat the system, and prevent the existence of air or water in the system, resulting in gas explosion, damage to seals, and accidental failures such as leakage in the cylinder.
(2) The hydraulic cylinder needs to extend the piston part out of the cylinder in the work, which will be eroded by oxide and acid gas, resulting in rust, and it is necessary to regularly apply lubricant or grease to the piston to prevent failure or breaking of the piston.
(3) Protect the outer surface of the piston rod to avoid bumping or scratching the seal and causing damage to it.
(4) Regularly clean the sediment on the cylinder seal ring and piston rod to avoid the dirty debris stuck on the surface into the cylinder and damage the piston, cylinder or seal.

(5) Regularly check the connection parts such as threads and bolts to ensure that the fastening is firm.
(6) Control the system temperature, the oil temperature is too high will reduce the service life of the seal, long-term so will make the seal deformation, or even failure.
(7) Familiar with the sound of the system operation, when the abnormal sound is heard, check and exclude in time to avoid serious problems and cause large losses.
2. Replace hydraulic oil regularly
(1) The hydraulic cylinder may enter dirt or foreign matter after long-term work, which will increase the friction force, and cause damage to the hydraulic cylinder when the parts of the hydraulic system are excessively worn. Only need to replace the hydraulic oil and cleaning system filter regularly to ensure the cleanliness of the hydraulic oil and extend the service life
(2) Regularly check the amount of hydraulic oil, when the amount of oil is reduced, the air into the system will run abnormally.
(3) Pay attention to check whether the hydraulic cylinder has oil leakage during daily maintenance, check the oil leakage need to replace the seal in time, responsible for the loss of oil is small, damage to the hydraulic system is big.
(4) Regularly check whether there is rust or wear in the lubrication connection.
3, the hydraulic cylinder is equipped with a buffer device to avoid improper operating speed affecting the service life. The hydraulic cylinder speed is controlled at two meters per second, which can make the hydraulic cylinder work safer and effectively extend the service life.
4. Check whether the tight part is loose, regularly check and timely replace the O-ring seal of the faulty cylinder piston to ensure the smooth operation and service life of the cylinder.
The above is the total content of the daily maintenance measures of the hydraulic cylinder, I hope to help you! Through the introduction of small series, we can understand how to carry out maintenance and maintenance of hydraulic cylinder, and realize the importance of maintenance and maintenance for the operation of hydraulic cylinder.
