Problem summary tanker general failure analysis and elimination
| Fault phenomenon | Cause Analysis | Method of exclusion | |
| Can't suck or suck too little | 1 Engine speed is too low 2 No oil in the pump 3 suction pipe leak, low vacuum 4 suction pipe plugged 5 Suction pipe in the three-way ball valve is not off 6 The coarse filter is seriously blocked 7 oil pump worn or damaged 8 Intake valve cannot open in vent valve | 1 Increase engine speed 2 Refueling 3 block the leak, increase the degree of vacuum 4 Remove plugs 5 Turn the ball valve stem and turn the color point to a stop 6 Cleaning strainer 7 Repair or replace the oil pump 8 Repair vent valve, otherwise easy to suck the tank | |
| No oil from the tank or too little oil | 1 Valve is not open or incomplete 2 Freezing water in sedimentation tank 3 Dirty inside the tank, blocking the oil drain 4 vent valve blocked, poor air intake | 1 Open the valve 2 Use steam to open the ice and open the sediment to release water 3 Cleaning up dirt 4 repair vent valve | |
| PTO is not working properly | 1 Gear wear or excessive gasket between power take-off and gearbox 2 The spacer between the power take-off and the transmission is too thin, the center distance is short, the rotation is difficult, and the gear is easily damaged or the power take-off shell is crushed 3 The power take-up fork is damaged or the cylinder is damaged. 4 Pneumatic valve damage can not control the gas circuit 5 oil seal or gas gasket damage, oil spill | 1 Change gear or thin gasket 2 thick gasket 3 Replace fork or repair cylinder, piston 4 repair or replace the pneumatic valve 5 repair or replace the oil seal, gasket | |
| Drive shaft shakes badly | 1 Drive shaft bending 2 Poor balance 3 PTO output shaft bearing or oil pump speed increase input shaft bearing wear is serious 4 Gimbal connection bolts loose 5 Front and rear universal joint installation direction is wrong 6 Cardan joint or telescopic spline worn badly | 1 Straightening shaft 2 Do a dynamic balance test 3 Replace the corresponding bearing 4 fastening bolts 5 Adjust the orientation of the universal joint 6 Replace the new universal joint or replace the new one directly | |
| Tank or piping system leaking oil | 1 There are pores and trachoma in the welding area 2 road mine is not good, the vehicle is bumpy, and there is a tear | Add air pressure to the tank to 36Kpa. Brush soapy water in each part and find the leaking part. After cleaning according to the method described above, repair welding. | |
| Ball valve leakage | Loose end cap bolts 2 Three-way ball valve bottom adjustment seat loose 3 valve body with trachoma or pore 4 "O" ring damage at valve stem | 1 Tighten the bolt 2 tighten the adjustment seat 3 Replacement of new ball valve 4 Replace "O" ring | |
| Ventilation valve failure | 1 Inlet and exhaust spring failure 2 inlet, exhaust valve stuck | 1 Replacement spring 2 Reassemble and remove stuck objects | |
| Flow meter failure | 1 Miscellaneous objects stuck in the flowmeter in the elliptical rotor 2 Oval rotor damaged | 1 Cleaning debris 2 Replace the rotor | |
