Spraying machine in daily use due to the construction of the environment and the particularity of construction materials, will cause a series of abnormal damage to spraying machine, together with the use of the incorrect operation mode, more aggravate the failure rate of the machine.How to reduce this unnecessary failure rate, the following to give you a few common faults in the construction and quick troubleshooting methods.

The first does not suck.The most common problem is that the plunger moves up and down normally and the machine does not suck.This situation is usually caused by the size of the ball, sealing ring, upper and lower seats, these components.The most probability to the size of steel ball size ball closed lax or jammed, the cause of this situation is usually inhaled particles larger pad in the pump body between the ball and seat, or squeeze between the ball and cage ball and valve seat can't completely fit cause leakage, unable to form a negative pressure in the pump body, causing no absorption material.In addition, if the machine is not used for a long time, the steel ball will stick to the ball valve, resulting in the ball can not be opened, and will not suck material.

So how to quickly understand the big ball or small ball, is very simple now would be a big ball of the cylinder block removed from the pump body, will remove the mouth up to its internal water see whether there is a suction mouth out the water out, if you don't have to use wood from below dial the ball the ball freely up and down the water flow is normal, if everything is all right big ball: no problem.If the water does not move the ball, the water will flow out from below. Then it is necessary to see whether the ball is contaminated or whether the ball is stuck to the ball valve.Because the small ball is not easy to observe then there is no problem with the elimination of the large ball or suction is the problem of the small ball.
