What causes the sprayer not to spray

There is no error in the normal use of the sprayer, but after working for a while, there will be a phenomenon that it cannot be sprayed normally. What is the cause of this phenomenon? As a professional manufacturer in this area, we will tell you what is the cause today, let's take a look.

The sprayer manufacturer tells you that, first of all, the liquid pump valve is seriously worn, or there is a foreign matter stuck in the middle, or the spring is damaged, causing the valve and the valve seat not to be tightly closed.

Secondly, there are many impurities in the water source, and the filter screen is not cleaned in time, so that the surface of the filter screen is dead, and the amount of water is reduced or not. At this point or the visible suction tube is sucked.

Furthermore, there is foreign matter in the pressure regulating valve port, or the valve column is increased in friction due to lack of oil, so that the valve cannot be reset. At this point, a large amount of liquid medicine flows back to the medicine box to lower the pressure.

Fourth, the liquid pump with the air chamber, the air pressure in the air chamber is too low or too high, can not absorb the pulsation of the liquid medicine, at this time, the water outlet pipe of the liquid pump is violently shaken. The suction pipe leaks due to corrosion or aging, or inhales foreign matter. The oil in the liquid pump is worn out and missing, which reduces the pressure.

The specific reasons why the sprayer can not be sprayed have already been told in detail above. If this happens, we must deal with it in time so that we can work better.
