Following are some important items that should mind if you own a concrete mixer:Oil and circuit and control equipment inspection at the lubrication, add oil as required. Before each shift, water in the mixing bucket idle 1-2 minutes, but check the clutch and brake device reliability of the work. Concrete mixer during operation and be ready to listen to the motor seized, reducers, gear noise is normal, the temperature rise is too high. After completion of the work shifts should be carefully cleaned concrete mixer. A concrete mixer general maintenance work after 100h for primary care.
1, concrete mixer in the primary care, in addition to including the content of the work routine maintenance, but still need dismantling the clutch, check and adjust the brake clearance, such as the clutch inner and outer brake band wear off even be replaced. Also check the rope, V belt bearing, water distribution systems and running wheel.
2. compulsory concrete mixer at maintenance level, the gap between the blades should be checked and adjusted stirring blade and the liner between the hopper and the discharge door seals and flexible, the degree of wear of the clutch of the normal level of the water distribution system algorithm .
3. Using a rotating concrete mixer chain need to check chain pitch elongation case two maintenance concrete mixers two maintenance cycle is generally 700 ~ 1500h hours of work, two maintenance in addition to a work-maintained, shall be demolished check reducer, motor and open gears, etc. Also you need to check the machine and the operating mechanism of the material, cleaning the road wheels and the steering mechanism and the like.
1. dismantling the reducer shall wash gear, shaft, vomiting and oil channels, check the wear surface dismantling halogen profile is completed, add new gear oil.
2. Dismantling the motor should remove dust on the stator windings, cleaning bearings and filling new grease, check and adjust the gap between the stator and the rotor.
3. Dismantling the open gear, the need to clean the gear tooth profile, weeks and bearings, checking wear, excessive wear should be replaced. The material on the inner and outer clutch brake band, such as excessive wear should be replaced.
5. The concrete mixer chassis skew deformation, should be repaired or corrected.
6. Dismantling the amount of water, a straightened position of the sleeve, remove the suction pipe and casing around and rot and rust on the inner lever on the brush rust.
7. When the check split three-way valve, the valve chamber should be cleared and pipe joints nearby rot rust and scale, so to keep the waterway open. 8. specific institutions, such as rubber roller, the trip switch, meter, solenoid valves, etc., can be adjusted periodically check and cleaning according to the situation
