The principle of water outlet of the spray pump
Jan 06, 2018

Exhaust process:

It is assumed that there is no liquid in the base workshop in the starting state. Press the pressing head, the compression rod drives the piston, the piston pushes the piston seat to move down, the spring is compressed, the volume is compressed and the air pressure increases in the workshop, and the sealing valve is sealed by the water stop valve. Because the piston and the piston seat are not completely closed, the gas squeezes the gap between the piston and the piston seat, so that it separates and escapes.

Water absorption process:

After discharge, release the pressing head, release the compressed spring, push the piston seat up, and the clearance between the piston seat and the piston is closed, and push the piston and the compression rod move up together. In the workshop, the volume increases and the air pressure decreases, which is similar to the vacuum. It makes the water stop valve open the pressure above the liquid level in the container and pump the liquid into the pump body to complete the water absorption process.

Effluent process:

The principle is the same as the exhaust process. The difference is that at this point the pump is filled with liquid. When you press the pressing head, on the one hand, sealing the valve seal to prevent liquid from the upper drain pipe, drain pipe back to the container; on the other hand, because the liquid (incompressible) by extrusion, liquid will open gap of piston and piston seat, into the compression tube. And out of the nozzle.
