How much do you know about the maintenance of wet concrete sprayer?

Issue Time:2022/06/06
The essence of wet concrete spraying machine operation is to add a certain kinetic energy to the concrete, overcome various resistances and the quality of the concrete itself, and attach it to the excavation surface. The whole operation includes the whole process from power generation to termination on the excavation surface, and the whole process from the unloading of concrete from the tanker to the termination on the excavation surface. The application of wet spraying machines in tunnel construction is also becoming more and more common. More and more customers will always encounter many problems in the process of using the wet spraying machine. There are some questions about the maintenance of the wet concrete spraying machine? How much do you know about the maintenance of the wet concrete spraying machine?

1. When does the oil in the wet concrete sprayer need to be replaced?‍

Check the oil level and oil quality of the hydraulic oil. The oil quality should be light yellow and transparent, without emulsification or turbidity, otherwise it should be replaced immediately. When the air leakage on the side of the rotor body is serious, check whether the gap between the limit seat and the hopper seat is suitable.

2. Does the wet concrete sprayer run fast or slow?‍

You should first check whether the voltage is stable. If the voltage is normal, you need to check the working condition of the lubrication system. You should see that the indicator rod of the progressive distributor moves back and forth, and there is lubricating oil on the smooth points such as the bearing position of the swing arm end of the S tube and the bearing position of the mixing shaft. Overflow; then start the machine again to investigate whether the distribution valve reversal and the positive rotation of the mixing equipment are functioning normally. When the pressure of the wet sprayer is small and the eruption effect is not ideal, it is possible to check whether there is oil leakage or oil leakage in the hydraulic system. Always check all threaded connections of the wet sprayer to ensure that the connections are strong.
