Pump and fan - reciprocating pump

Now with piston type as an example to illustrate its working principle.As shown in figure 1,permanent magnet motor 7,piston pump is mainly composed of a piston in the pump cylinder for reciprocating motion within 2 to 1 liquid inhalation and ruled out.When the piston 1 started from the far-left side to the right position,studio 3 volume gradually expand,indoor pressure is reduced,open fluid suction valve 4,into the piston 1 release space,until motor run capacitor l piston moves to the far end of the process for the pump suction process.When the piston 1 right from the beginning,the move to the left side of pump fluid by squeezing,close the valve on the electricalmotor1.blogspot.com suction,pressure and open the water valve 5 and discharge,this process is called process of pressurized water pump.Piston reciprocating motion,the suction of the pump is continuously alternating with pressurized water process.The motor magnet pump working principle is actually like the compressor refrigeration system,so we are not in this explanation,and behind the compressor parts in detail.This pump is suitable for small flow,high pressure,in a large refrigeration unit used more.
