Daily Maintenance of Concrete Mixer

Cleaning the body of the concrete mixer to remove dirt and obstacles on the body. Check the oil and electric circuit and control equipment of the lubrication department and fill in the lubricating oil as required. Class work, water in the mixing barrel idling 1 to 2 minutes, and to check the reliability of the clutch and brake device work. In the course of operation of the concrete mixer, it is time to check the motor, the reducer, the noise of the transmission gear is normal, and the temperature rise is too high. After each shift, the concrete mixer should be carefully cleaned.
Primary maintenance
Concrete mixer general working 100h after the first level maintenance.
1, concrete mixer in primary care, in addition to the daily maintenance of the work, still need to dismantle the clutch, check and adjust the brake clearance, such as the clutch, the outside of the belt wear is required to replace. In addition, it is necessary to check the wire rope, V with sliding bearing, with water system and walking wheel, etc..
2 compulsory concrete mixer in the primary care, must check the adjustment of the gap between the blade and the scraper and the lining plate, on the hopper and unloading door sealing and flexible, the clutch wear degree of a graded water system algorithm.
3 the concrete mixer with chain rotation needs to check the extension of chain pitch.
Two level maintenance
Concrete mixer of the two level maintenance cycle of general 700~1500h hours, two maintenance, in addition to the maintenance of the work, the need to dismantle and check reducer, motor and open gear, etc., in addition to check the machine as well as the material of the control mechanism, cleaning the wheel and steering gear.
1. Dismantling the reducer should be cleaning gear, shaft, shaft vomiting and oil, check the brine profile surface wear degree demolition inspection is completed, add new gear oil.
2 when the motor is removed, the dust on the stator windings should be cleared, clean the bearing and fill in the new lubricating oil, check and adjust the clearance between the stator and the rotor.
3 open the test of open gear, need to clean the gear tooth profile, and the bearing, check the wear condition, the wear should be replaced when excessive.
4 clutch clutch inside and outside the brake belt, such as excessive wear and tear should be replaced in time.
5 when the concrete mixer rack is deformed, it should be repaired or corrected.
6. When removing the water measuring device, adjust the position of a sleeve pipe to clear the suction pipe and the casing around and lever of rust and brush antirust paint.
7 dismantling the three-way valve, should be cleared near the valve chamber and the pipe interface rust and scale, the waterway unblocked.
8 pairs of special institutions, such as rubber roller, travel switch, water meter, solenoid valve, etc., can be adjusted according to the situation and cleaning.
