In the working process of the swing cylinder, it is often because of the lack of individual parts or the damage of individual parts that affect the use and construction period of the entire machinery and equipment. Therefore, users and friends should be able to be flexible in the use and maintenance of swing cylinder Deal with some seemingly tricky issues.
1. Incorrect installation of parts, for example, the elasticity of the support ring (mainly made of filled with Teflon material) in the seal of the hydraulic cylinder in some construction machinery is poor, so it should be in 100oC oil before installation. Soak for 10-20 minutes to make it soft, and then install it when its elasticity is greater.
2. Problems in the operation of parts and components, which cause more problems, especially when the new driver is not familiar with the performance of the machine during the operation of the engineering vehicle. For example, the spline of the semi-axle of an engineering vehicle is often worn out. Later, it was discovered that the driver kept the differential lock off, which caused the load on the transmission part to increase during use, causing serious wear and tear, so the operation should be improved.
3. The failure of the relevant parts caused the damage to the parts. For example, two walking hydraulic motors on one excavator were broken at the same time. After inspection, it was caused by the oil seal on the multi-way rotary joint being damaged and the circuit was blocked. This problem, otherwise the hydraulic motor will be damaged in the future.
4, the quality of hardware parts, such as an excavator, its hydraulic motor, hydraulic pump, reducer bearings have been damaged, after replacing the original bearing is still broken, and then install imported bearings to solve the problem. Similarly, the oil seal of this excavation motor arm cylinder was often damaged in the summer, and it was later found that the gap between the original piston and the cylinder barrel was too large. After the piston was reprocessed on site, the oil seal was not damaged.
The above is the introduction of the abnormal working performance of the swing cylinder parts. It is recommended that everyone check and maintain before using the cylinder to ensure normal work.
