How to determine whether the concrete mixing plant is maintained in place?

How to determine whether the concrete mixing plant is maintained in place?

First. Maintenance check of the control room.

　　The control room is the base of the mixing plant, it is equivalent to the human brain, the control room has electrical components such as industrial control machine, monitor, operation desk, power cabinet, etc., and the electrical components are not afraid of water, dust and fluttering

　　So into the control room should first check whether the indoor environment is clean, neat, industrial control machine is not placed smoothly, power cabinet air switch, communication contactor terminals are not fastened.

Second. Check the maintenance of the main mixing machine.

　　The main mixing machine is the key component for mixing various materials into concrete, and its maintenance will directly affect the service life of the mixing plant.

　　1. Lubrication check of the main machine

　　When the main mixing machine is working, you can check whether the grease pump scraper is scraping oil in normal operation.

　　2、Inquiry grease pump pressure gauge value

　　The normal working pressure is 10, if the pressure is lower than 10, the grease pump core may be blocked, if the pressure is higher than 60, the distribution valve may be blocked or the rear pipeline may be blocked.

　　3、There is a spare grease nozzle in each shaft head

　　Use finger nail to press down the top bead of grease nozzle, if there is grease out, it proves that the shaft head lubrication is in place, and vice versa, it proves that the shaft head lubrication is not in place.

　　4、In the automatic production state

　　The manual handle of the discharge door of the mixing machine should be in the retracted position, and the ball valve is in the middle position, and the two hand automatic change screw plug should be tightened to avoid premature damage to the hand oil pump.

     5、Mixing mainframe gearbox should pay attention to timely refueling and oil change

Check whether the gear oil is satisfied, to ensure that the oil level of the oil indicator can be checked.

      6、Check whether the reducer box has the appearance of oil leakage

Call plate host reducer box easy to leak at the input and output shaft seal, oil temperature sensor.

     7、Mixing shaft and mixing blade should be cleaned in each working cycle to avoid caking and holding shaft.

Third, screw conveyor maintenance inspection

1、The gear oil level of screw conveyor reducer should be above the red line of the oil indicator, and the reducer should work without noise and abnormal sound.

2、The manual butterfly valve of the discharge port should be closed to avoid powder entering the screw machine.
