Variable plunger pump how to adjust the flow?
For the electromagnetic valve control inclined disc type plunger pump, because the inclined disc and cylinder into an Angle, so when the cylinder rotation, plunger in the pump cylinder to do reciprocating movement. It from 0 ° to 180 °, or go to the top position of the plunger and plunger cylinder volume increases gradually, so the liquid of oil distribution plate of oil suction mouth suck oil cylinder; And the plunger is from 180 ° to 360 °, the plunger cylinder volume decreases, so the liquid in the cylinder oil distribution plate of the outlet of the liquid.
As long as the drive shaft keeps rotating, the pump keeps working. Changing the current in the solenoid valve can change the Angle of the tilting element, and then change the plunger in the pump cylinder stroke length, that is, change the pump flow. Tilt Angle fixed known as quantitative pump, tilt Angle can be changed known as variable pump.
Also pay attention to the pump outlet pressure requirements, the outlet plus return line, can return to the inlet or raw tank can be; Adjust the pump outlet relief valve pressure can be considered. Raw materials in the premise of meeting the needs of dilution, increase the amount of injection, to achieve the metering pump in the larger flow work, accurate measurement.
