HZS180 concrete mixing plant manufacturer after-sales manual - common failures

 

HZS180 concrete mixing plant manufacturer's after-sales manual of common faults and troubleshooting methods.

 

I. Supporting cement storage and supply system

 

The cement screw conveyor is slow to feed or overloaded and stuck. The solution is relatively simple, just check the arch breaking work, remove the foreign matter, reverse the spiral shaft to remove the blocked material.

 

Second, the aggregate supply system

 

1、The hopper of aggregate is cheap or stuck. This kind of reason is mostly for two lifting oil wire rope length is not the same or oil wire rope jumping slot, after adjusting the oil wire rope length and adjusting the lower limit for sensitivity and adjusting the anti-skipping device can be solved.

 

2、After unloading the aggregate hopper, it does not fall according to the program control. This kind of reason is mostly because the travel switch is out of order to repair and replace.

 

3, the winch overheating mainly because the brake device gap is not suitable, found after the motor brake device must be adjusted immediately.

 

Third, the aggregate and cement and admixture measurement system

 

1, cement measurement is not allowed. The main reason is generally the hopper stained with too much material, knife bearing, knife blade between foreign objects or lever system weighing hopper is jammed by foreign objects, can not be free shaking, overhaul the vibrator and remove foreign objects to remove the fault, such as measurement is still inaccurate need to recalibrate or replace the sensor.

 

2, gravel bucket measurement is not allowed. The main reason is that the gap between the permanent material door and the door frame is too large, the knife bearing, knife blade between the foreign body needs to replace the rubber plate or material door; check the pressure of the air source or overhaul the cylinder to see if the side and bottom of the weighing frame is stuck by foreign objects; if the sensor permanent calibration constant and the actual discrepancy need to correct the material door.

 

Fourth, the mixing system

 

1, mixer host vibration is too large. The main reason is that the gap between the mixing blade and the tank liner is too large and uneven, the main drive open gear bite is not good, need to adjust the gap between the mixing blade and the liner, adjust the open gear bite side gap and contact length.          2, mixing host unloading door opening and closing does not work. The main reason is that the cylinder force is too small or the gravel is stuck, need to check the pressure of air source or overhaul the cylinder, adjust the gap between the discharge door and cylinder wall seal.

 

Five, admixture system

 

1, admixture pump does not turn. First of all, check the line, see if the power line connector is off, such as impurities found in the admixture foreign matter need to repair or replace the screen, pump impeller stuck does not turn need to disassemble the pump cleaning pump shell.

 

2, admixture measurement is not allowed. Mainly due to the lower sensitivity of the proximity switch, need to adjust the proximity switch or replace to restore the accuracy of measurement.
