First, check the lubrication of the lubrication points of the operation parts of the hzs90 concrete mixing plant.

1-axis seal: for the use of centralized oil supply of concrete mixing plant, in the work can not only rely on automatic lubrication, must be accompanied by manual inspection, while the quality of lubricating oil must be qualified.

2 oil mist: check the liquid level down, observe the berth color. Air supply processing Three components of the oil mist fuel supply can be adjusted by adjusting the size of the throttle, that is, adjust the side of the font screw to control. Oil mist oil must be cleaned and added in time.

Second, check the electrical device is safe and reliable, check the motor, solenoid valve and other electrical components and control system wiring is reliable, the power supply voltage fluctuations must be less than or equal to five percent.

Moreover, for the gas system should be done: check the air compressor oil, so that it remains on the oil surface close to the line, add new oil. Observe the air compression hungry and the oil and water separator, timely discharge of condensate. Make sure that the pressure gauge is working properly and that the pressure relay switch is operating within the specified pressure range and that the air pressure is 0.7MPa. Check the gas pipeline for leaks. Air part of the pneumatic components, such as solenoid valves, gas-water separator and other components of the working environment temperature of 50 degrees, work should pay attention to the level of ambient temperature.

Finally, check whether the operation of the concrete mixing station is running normally, there is no deviation in the conveyor belt, between the belt and the driven roller, whether there is any foreign matter falling, if abnormal circumstances, immediately stop troubleshooting. To prevent sand and gravel mixed with steel, large stones and other debris, is strictly prohibited to purchase blade-like stone to avoid damage to the conveyor belt.
