The water cutting machine needs to be equipped with a water supply system, and in order to prevent water leakage when the pipe is connected, it is necessary to increase the thread of the steel pipe head by more than three teeth. If it is found that there is a fault in the water cutting machine, but can not determine whether the fault point is in the water or oil, it can be further judged by way of disassembly.
Remove the water section of the water cutter first, then turn on the oil pump and high-pressure water switch to observe whether the cylinder piston is commutating normally, so as to determine whether the problem is a waterway fault or an oil circuit fault. After finding out the problem, it will be much easier to solve it.
In the supercharger of the water cutting machine, grease is added at the place where the sealing ring is installed; at the same time, the oil temperature of the supercharger should be reduced as much as possible, which will help to greatly improve the life of the sealing ring. Reduce the use of equipment.
For water cutter high pressure cylinders and low pressure cylinder heads, it is recommended to loosen the threads at intervals of two or three days to prevent high pressure cylinders and low pressure cylinder heads from being tightly connected. And can use both hands to touch the high and low pressure parts at both ends, so quickly determine which side of the high and low pressure check valve seal is not good, if the seal is not good, then you need to adjust.
It should be noted that properly reducing the water cutting machine pressure not only does not reduce the cutting efficiency, but also can greatly increase the life of wearing parts.
