The use of wet mix shotcrete machine in engineering construction has become very common, but long-term use of the equipment, especially on the basis of lack of maintenance, is easy to cause large or small problems. If it is not resolved in time, the progress of the project may not be affected for a while, but small problems cannot be solved for a long time. No matter how small a problem will eventually lead to a larger problem, it will be too late to regret it. Why is the efficiency of wet mix shotcrete machine construction getting lower and lower?
1.Belt conveyor and cylinder do not work
When the belt of the wet mix shotcrete machine is running, check the operation of the rollers frequently. If it is found that it does not rotate, replace it in time. Do not work with disease, otherwise it will cause the belt to be damaged. replace. Remove and remove the sludge inside the cylinder.
2. Slow working speed
The slower operation speed of wet mix shotcrete machine is mainly due to the wear of the whole machine, which causes the engine power to drop and the hydraulic system to leak. The hydraulic pump of the wet sprayer is a plunger variable pump. After working for a certain period of time, the internal hydraulic components of the pump will inevitably cause excessive wear, which will cause internal leakage and inconsistent data. slow. At this time, the entire machine needs to be overhauled, and repaired and replaced the worn out parts.
3. Solenoid valve does not work
When the wet mix shotcrete machine controls the solenoid valve on the operation panel, the solenoid valve cannot be opened manually or automatically. Replace the solenoid valve coil or the pilot valve or the operation button; when it cannot be turned on manually, the solenoid valve should be replaced when the air outlet vents. When it cannot be opened manually, when the lower outlet of the solenoid valve is exhausted, check whether the inside of the cylinder, the seal ring, the piston rod, the compression screw, etc. are leaking.
