Aggregate dosing machine prohibit open electromagnetic valve
Aggregate dosing machine prohibit open electromagnetic valve when not working, bucket elevator institutions due to leaving the brake air gap increases brake lining wear, brake pull the sound will be larger, serious phenomenon will produce brake can’t pull, causing the motor burned, and therefore must regularly test the brake air gap and check the brake torque. When the braking air gap greater than 6 mm should loosen the nut 1 nut 2, adjust the brake coil, concrete batching machine to ensure that the entire circumference of the brake air gap in the range of 0.1 ~ 0.2 mm, and then tighten nut 1 and nut can. Braking torque adjustment nut loosen and tighten the nut 4 compression brake spring to increase the braking torque. Loosen the nut, relax the brake spring braking torque. The braking torque can’t be adjusted too much, otherwise it will causes the brakes not open. Braking torque adjustment is completed, tighten the nut 3 can. Regardless of braking torque transfer large or transfer small adjustment shall make three brake spring compression heights consistent,aggregate dosing machine in order to avoid uneven braking piece due to power damage. Should always check the wire rope a chuck fixed and wear situation, When wire rope every pitch wire breaking number of more than 5% of the total root root, should be replaced for maintenance and overhaul should be hopper raised to the top dead center, with a track on the safety pin lock. Mixing station to run the first week of the lifting mechanism should be checked daily limit connection bolts loose. Before each formal operation manual lifting and landing enhance the bucket, concrete paving machine to determine whether the limit switch flexible and reliable. The second limit switch should be checked once a day is flexible and reliable, checked weekly limit switch reliability. In the first week of the concrete batching plant using powder positions the basis of whether the settlement must be tested daily. Powder before filling the positions for the first time, it must be the silo residual debris clean up. Filling the powder or maintenance to replace the discharge gate to the warehouse for the first time, you must check the seal of the gate. The cement silo gas arch breaker should be checked regularly to ensure it is in a normal state. Powder positions in the screw conveyor is not working during concrete batching machine prohibit open the broken arch electromagnetic valve, to avoid compressed air into the silo.
