Repair, maintenance and a concrete stirring transport vehicle
The car used as transportation of concrete stirring transport vehicle, in terms of maintenance and repair must comply with the provisions of the Ministry of communications in 1990 13 orders, the implementation of the "regular testing, forced maintenance, timely repair" maintenance and repair system. In this context, combined with the actual situation of concrete stirring transport vehicle, good maintenance and repair. In the daily maintenance, concrete mixer truck except as routine maintenance of automobile engine, chassis and other parts, also must do the following maintenance work.
1, cleaning concrete tank (mixer truck drum roller) and inlet and outlet
Because of the concrete in a short time will solidify into lumps, and paint on steel and have a certain corrosive, so every time the use of concrete tank, cleaning adhesion is daily maintenance must seriously work carried out in the concrete tank and the inlet and outlet of the concrete. Including:
A. every time charging before flushing with water inlet, the inlet when in charging moist;
B. filled with water to clean water tank with the car comes in charge at the same time;
C. loading washing after feeding mouth wash, feed near the mouth of the residual concrete;
D. to the site after unloading, flushing out feed channel, and then to the concrete tank and cleaning water 30 - 40 L; keep the concrete tank forward slowly rotate in the vehicle when you return;
Next time before you go E. filling concrete tank sewage;
F. the end of each day when thoroughly clean the concrete tank and inlet and outlet around, guarantee not to stick with cement and concrete caking. The above work as long as one does not
Seriously, has caused great trouble will give the future work.
2, the maintenance of the driving device
The action of the drive device is driven to rotate it by concrete tank, hydraulic oil tank and a cooling device of power takeoff, Wan Xiangzhou, hydraulic pump, hydraulic motor, the control valve, consisting of. If this part due to failure to stop work, concrete tank will not rotate, this will lead to concrete scrap car, even the whole pot of concrete setting in the tank, causing scrap concrete mixer truck. Therefore, the driving device is reliable or not is must attach great importance to the problems in use. In order to ensure the driving device is intact and reliable, should do the following maintenance work:
A. universal rotating part is the fault of multiple parts, should be timely grease, and regularly check the wear, timely repair replacement. The team should have spare cardan shaft assembly, to ensure that the event of failure to return to work in a few minutes.
Ensure the cleanliness of the hydraulic oil b.. Concrete mixing truck working environment is bad, we must prevent the pollution of cement sand into the hydraulic system. Hydraulic oil according to the manual requires regular replacement. Once the inspection found that hydraulic oil mixed with water or sediment, must immediately stop cleaning and replacement of hydraulic oil, hydraulic system.
C. ensure that the hydraulic oil cooling device effectively. To regularly clean hydraulic oil radiator, the radiator is avoid cement plug, check the radiator electric fan is functioning properly, to prevent the hydraulic oil temperature exceed the standard. The hydraulic part as long as the guarantee of clean hydraulic oil, the general failure not much; but to different manufacturers, the service life is not the same.
