Roller roller maintenance costs _ _ Xi'an Yulin Chengtong hydraulic service

Steering abnormal sound noise is due to the drive pulley Songkuang, fixed steering pump bolts loose or oil storage due to the low level. Combined with the above circumstances, we should be the proper use and maintenance of hydraulic pressure steering mechanism in practical work. Specifically should do the following: 1. regularly check whether lack roller steering hydraulic oil maintenance Which is good, such as the lack of timely additional same time, regular cleaning of hydraulic oil cups and filters, to prevent the hydraulic oil is too dirty or bad, every proposal with 30000km Replace the hydraulic oil. Oil temperature is too high: When the hydraulic system, to control the oil temperature, the temperature is too high, it will produce the following phenomena: ① roller maintenance make in most cases, when the oil temperature is often above 60 ℃, the oil viscosity declined significantly, Not only the lubricant film thinning, increase friction, increased wear, and seals expansion, aging, failure, resulting in a hydraulic system leak. Studies show that roller repair factory, the oil temperature is increased by the seal of the life of 10 ℃ will be halved. ② after the oil temperature, volume expansion roller maintenance, pressure increases, and the leakage increased with increasing pressure, so that the leakage increases. ③ temperature rise contraction of the expansion of the gap. General combining parts of different materials, different coefficients of thermal expansion, when the temperature rise, with different parts shrink due to changes in inflation, with the gap will change, when the gap becomes larger, resulting in increased leakage roller compactor maintenance costs _ _ Xi'an Yulin Chengtong hydraulic service provided by the Xi'an Chengtong hydraulic maintenance Limited.
