First, the lubrication of the gear oil pump is carried out by the liquid discharged by itself (the grease replacement of the motor depends on the use condition). The liquid to be discharged must be cleaned. If the fine dust or metal powder is caught, the service life of the pump will be Severe effect. If necessary, install a metal oil filter net at the end of the suction pipe to prevent the inhalation of impurities. The oil filter net should be 60-100 mesh/hour and the effective filtration area should be more than twice the cross-sectional area of ​​the oil suction pipe.
Second, the height of the gear oil pump installation should be guaranteed not to exceed the suction height allowed by the pump. The installation pipeline should have a pipe rack and the oil pump is not allowed to bear the pipeline load.
3. It is recommended to install a vacuum gauge and a pressure gauge on the suction and discharge lines to monitor the working state of the pump.
4. Preparation before the gear oil pump is started:
1. Check whether the nuts on the oil pump and the bolts on the base are tight;
A. Carefully check all parts of the pump before the oil pump is turned on;
B. Check whether the rotation of the driving gear and the driven gear in the oil pump is flexible;
2. Check if the power supply of the motor is connected and the direction of the oil pump is the same as that of the indicator arrow, that is, the bearing is rotated clockwise;
3. Open the valve of the oil suction pipe and the oil discharge pipe.
5. Maintenance of gear oil pump during operation:
1. Note that the readings of the gear oil pump pressure gauge and vacuum gauge should conform to the technical specifications;
2. Pay attention to the working condition of the shaft seal of the gear oil pump. If the oil leakage should respond to the packing seal structure, the pressure cap should be evenly tightened, but it should not be too tight to avoid the heat and the rapid wear of the seal ring. When the oil leaks, the oil seal should be replaced in time. ;
3. Regularly check the heat of all parts of the oil pump;
4. When it is found that the gear oil pump has abnormal noise or excessive heat, the oil pump should be stopped immediately to eliminate the fault;
5. Always keep the oil pump work site clean. Article from: http://NewsDetail247T2.html China Hardware Business Network http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com .cn
