Abnormal liquid indicates the presence of a malfunction

The cleaning of stains on the drive shaft gears is minimal and difficult to sample. Our company has conducted relatively few tests, but due to our limited testing, and our cooperation with Guangzhou Machine Tool Research Institute, in recent years,Lithium battery transport vehicleThe development project of equipment oil shape monitoring has been sent to Guangzhou Machine Tool Research Institute for testing. The kinematic viscosity of the oil sample sent by B727 forklift on January 20, 1998 at 40 ° C was only 67.4 mm2/s. On April 13, 1998, the viscosity of the oil delivered at 40 ° C was only 50.2 mm2/s, and the concentrations of Fe and Cu elements tended to decrease. However, the normal 40oC kinematic viscosity of differential gear oil MD Gx-90 was 180-200mm2/s, indicating that transmission oil (MD1310, 40oC kinematic viscosity) can be used. It is 36.8mm2/s and inserted into the differential.Container front craneThe differential gear oil of B718 forklift has been tested and similar situations have been found. I performed flashing and disassembly on two forklifts and found that the sealing ring (transmission frame oil seal) of the transmission and differential joint was damaged, and transmission oil entered the differential.
