( 4 ) When using a non- turbocharged diesel engine , diesel engine should calculate the actual power factor correction at the local , which is calculated as :
Ne = C • Neo (5-5)
Where : Ne --- corrected power ( actual power kW);
C --- correction factor ( see " Road Maintenance and Management Manual", Section 82 ) ;
Neo --- Rated power (kW).
The 14th section Fault inspection and removal
Vibration fault analysis and removal
Fault characteristics Failure reasons Elimination methods methodss
Only single file vibrations Vibration switch to the control solenoid valve circuit breaker between Check the vibration switch to vibration control solenoid valve circuit, will take a good break
Two tranches of no response or only a weak vibration vibration 1, F3 blown fuse
2, the circuit breaker
3, nylon sleeve coupling damage
4, severe internal pump wear
5 speed gear incorrect 1, replacing the F3 Insurance
2, check Y3.Y4 relay
3, when the circuit is recognized properly, the solenoid valve is working properly when the vibration motor can be drawn from the vibration of the wheel (not split tubing), nylon sleeve coupling check for damage, if damaged, replace
4, check the pump, such as its internal badly worn, you need professional maintenance
5, check the hydraulic motor, as they need professional repair severe internal wear
6, the gear shift to the I or II files
Weakness or vibration when the vibration compaction vehicle jitter 1, the engine is not working, the power is not enough
2, hydraulic filter clogging
3, severe internal pump wear
4, severe internal wear hydraulic motor 1, the engine power is not enough, the engine overhaul
2, replace the filter
3, check the pump, such as its internal badly worn, you need professional maintenance
4, check the hydraulic motor, as they need professional repair severe internal wear
Abnormal vibration frequency 1, vibration hydraulic system failure (such as: low efficiency, leakage, pressure, discomfort).
2, the engine speed does not apply
3, the pump displacement changes 1, check and eliminate vibration hydraulic system failure
2, it is set appropriate speed
3, the adjustment screw pump displacement limit
2, The driving system failure analysis and troubleshooting
Fault characteristics Failure reasons Elimination methods methodss
Driving weakness 1, the engine power is not enough
2, hydraulic oil filter element blockage
3, hydraulic pumps, hydraulic motors internal wear
1, the engine overhaul
2, replace the filter
3, excluded by professionals
When driving, the normal forward and backward unidirectional weakness Inside the pump control valve malfunction Excluded by professionals
Parking Zhidongshiling Serious friction pad wear or damage Adjust the gap by professionals or replace the friction plate friction plate
Walking speed anomaly 1, the engine throttle control loose
2, inadequate tire pressure
3, the engine speed does not apply 1, re-adjust the throttle control
2, to the tires inflated to the proper pressure
3, it is set appropriate speed
Before walking speed is inconsistent 1, the manipulation of soft plastic elongation
2, driving the pump regulator pin and interference with the pump housing 1，An adjustment shaft length
2, the pin installed upside down
Have a greater impact sound transmission or rotation is not flexible 1, bearing excessive wear
