The use of wet shotcrete machine in engineering construction is very common, but the long-term use of equipment, especially on the basis of lack of maintenance, is very easy to produce large or small problems. If it is not resolved in time, it may not affect the progress of the project for a while, but the small problem will not be solved for a long time, and then the small problem will eventually lead to more problems, and then it will be too late to regret it. Why is the construction efficiency of wet spray machines getting lower and lower?
1. Belt conveyor and cylinder do not work
When the wet spray trolley belt is running, check the running condition of the roller frequently. If it is found that there is no change, it should be replaced in time, and it can not be used for sick work. Otherwise, the belt will be scratched. The electric drum lubricant of the belt conveyor should be regularly checked and added in time. replace. Dismantle the cylinder to remove the sludge inside the cylinder.
2. Working speed is slow
The slower speed of the wet shotcrete machine operation is mainly caused by the loss of engine power and the leakage of the hydraulic system due to the wear of the whole machine. The hydraulic pump of the wet shotcrete machine is a plunger variable pump. After working for a certain period of time, the internal hydraulic components of the pump will inevitably produce excessive wear, which will cause internal leakage, and the data of each parameter will be uncoordinated, resulting in insufficient flow rate and high oil temperature. slow. At this time, the whole machine needs to be overhauled, and the parts with excessive wear and tear are repaired and replaced.
3. Solenoid valve does not work
When the wet shotcrete machine controls the solenoid valve on the operation panel, the solenoid valve cannot be opened manually or automatically, and the solenoid valve coil or the pilot valve or the operation button is replaced; when the manual valve is not opened, the solenoid valve is replaced when the gas outlet is exhausted; When the solenoid valve is not exhausted, check the inside of the cylinder, seal ring, piston rod, compression screw, etc. for air leakage.
