1. Water leakage of tubular oil cooler:
Block the two ends of the leaking tandem pipe; when the tandem pipe is enlarged, increase the seepage level again and press down to test the seal.
2. Oil leakage problem:
If there is oil leakage at the connection between the oil inlet pipe and the reducer housing, re-block, clean the seepage area and weld; if there is oil leakage at the housing connection, re-tighten and loosen the bolts.
3. The problem of insufficient oil pressure of the oil pump
After the original two-blade dual-flow oil pump of the main reducer oil station was operated for two months, the oil pressure dropped and fluctuated severely, and the final oil pressure was below the lower limit; due to the chain system control, the mill could not start: select and update 2 domestic oil pumps, and reconfigure Valves and pipes.
4. Oil pump motor overload:
Due to the low oil temperature and high oil viscosity, the resistance increases. By increasing the oil temperature, the problem can be eliminated.
5. Bolt loosening problem (the main reducer connecting ring and the shell bolts are loose, even 9 bolts are broken, and the radial limit pin is loosened or moved):
Remove the broken bolts, replace all high-strength connecting bolts and tighten them to stabilize the limit pin. It is recommended to tighten the connecting bolts (including anchor bolts) in various parts in time after the equipment is installed and operated for one month to prevent the body from loosening.
6. The original design of the reducer only has a temperature measurement point installed on the oil return pipe, and the temperature should not exceed 56 degrees, otherwise it will automatically alarm and stop, but it cannot truly reflect the actual situation of the bearing. Internal temperature conditions. It is recommended to consider the temperature measurement points of key parts in the design, grasp and understand the actual situation of each part, and solve and deal with problems in time.
