Matters that JS concrete mixer debugging need to notice
It is well known that a stirrer is a shaft with a blade which rotates in a cylinder or groove and mixes and mixes a plurality of raw materials into a mixture or a suitable consistency machine. Mixer is divided into a variety of, a forced mixer, single horizontal shaft mixer, double horizontal shaft mixer and so on. In the mixer debugging, we should pay attention to what matters, we for the Central China Construction Machinery Co., Ltd.
JS series of the mixer made the following summary:
1, to check the gear box and the lubricating parts of the lubricating oil is good enough.
2, check the power supply voltage: rated voltage of 380 volts, the error is ± 10%.
3, check the motor and electrical components wiring is reliable, the distribution box shell must be reliable grounding. The power supply zero line must be delivered to the wiring board N in the distribution box. All pipelines should be properly arranged to prevent the operation from crushing and causing accidents.
4, start the stirring motor, two axle rotation direction should be consistent with the direction of signs, such as the direction is not right, should change the power wiring.
5, start the coil motor lift hopper, hopper raised to the discharge position, it should automatically stop, Doumen automatically open. Hopper in the movement, if the motor power, the brake motor will hopper brake, if the hopper slippery volume greater than 50mm, indicating the brake moment is too small, should adjust the brake motor large nut to increase the braking torque.
Hopper down, in the horizontal fork out of the card, down to the bottom of the pit, the wire rope slightly loose, down the trip switch that action, the volume field automatically stop.
6, start the discharge mechanism, unloading door opening and closing should be accurate in place. Start the pump water, water supply system should be normal operation.
7, according to the required concrete ratio to determine the water supply, and adjust the time relay to the corresponding water supply time. Start the stirring motor running.
8, close the discharge gate, and then add the required mixture of hopper, hopper hopper. Should run smoothly and freely stop at any position on the track. If there is a slip phenomenon, should first be put into the pit bottom, and then adjust the brake motor on the big nut.
Hopper to improve the normal, reliable braking, the mixing tube to the same time to start the pump to the mixing cylinder water supply.
9, stirring 25-35 seconds after the start unloading door discharge.
10, in the above-mentioned trial operation process, if found abnormal, should immediately stop checking, troubleshooting, and then try again, know the normal so far. After the operation of the new machine should be used one day after the liner and other parts of the bolts, nuts all check fastening. Transmission lubrication parts for oil lubrication.
