Texas deep building tower crane slewing hydraulic coupler leak failure analysis

Texas deep building tower crane slewing hydraulic coupler oil 2020 - fault analysis 05 - 18 we agent for Texas deep building mechanical equipment in guizhou area of after-sales service. We have dealt with several equipment failure problems, including luodian site tower crane slewing hydraulic coupler failure analysis, the tower crane is double rotary reducer. Fault phenomenon: rotary hydraulic coupler oil, hair ring. Failure after investigation: through communication and tower crane driver, I learned about some situation. 一个。 Found in packed tower crane, tower crane turning speed slow. B。 After a period of time tower crane turning speed is normal, but one of the hydraulic coupler leak. C。 Driver to xuzhou tower crane manufacturers repair service, but manufacturers have not attach importance to the problem. D。 After a period of time again found hydraulic coupler hair ring, at this time did not notify the Texas deep built tower crane manufacturer for repair. The cause of the problem analysis: 1. Tower crane serious partial slow already belong to the abnormal phenomenon, two hydraulic coupler rotation direction is inconsistent, causing hydraulic coupler oil pressure is too high, one of the oil seal failure after the spill. 2. Hydraulic coupler after the spill, did not pay attention to xuzhou tower crane manufacturer. Hydraulic coupler leakage after bearing the lack of lubricating oil, lead to bearing wear after a ring. Maintenance treatment: dividing the discovery after oil seal is damaged, ball bearing damage, damage of o-rings, shaft have also been some damage. Will damage the two motor rotation after a change to the agreement after the commissioning, no oil leakage, hydraulic coupler running normal, normal speed rotating speed. Summary: the failure or reduce the losses can be avoided. If the tower crane driver found tower crane accident after serious slow rotation speed screening can completely avoid the failure occurred, there is no loss. After the hydraulic coupler leak, if xuzhou factory inform Texas built deep fault processing factory, will not cause the damage of the bearing, o-rings and shaft, change the oil seal, also reduced the economic losses. The failure reminds us that don't exist because failure without seriously, will lead to more failure, will cause more economic losses. The just cause failure, if it's caused the accident? The economic losses should not be so simple! And so maybe your life end, so not matter in a little. （ Guizhou highway engineering group co. , LTD. Set tube SiLiang silver fly)
