Be illustrated in figure 1 multistage electromagnetic incentive type piston pump in linear reciprocation, it is peripheral that multiple coil 2 is coated on tubular cylinder 3, and piston body 1 is in cylinder body 3, by the effect of coil 2 electromagnetic excitation, reciprocating between two ends in cylinder body.By motion, drive the liquid of piston body both sides or gas flow, the rectification pipeline formed by one-way valve piston body and one-way valve or be arranged on the rectification pipeline that cylinder body two ends are made up of 4 one-way valves, and then realize the object that liquid or gas unidirectional flow.
Be its fundamental diagram as shown in Figure 2, wherein, U1 is power supply, for governor circuit and coil provide operating voltage; Governor circuit controls chip selection signal; Between chip and coil, there are relay or triode, play the effect of electric current in control coil; Flow monitoring table monitoring liquid flow velocity, carries out time parameter, the correction of voltage/current parameter and control by signal feed back to governor circuit.
When U1 powers up, chip enable, the mode that right side pin circulates back and forth according to " running lamp " successively starts, and relay or triode are according to corresponding boot sequence closing coil power supply, and coil produces magnetic field and drives the mode that piston body circulates back and forth according to " running lamp " to move." external control " regulates the switching frequency of the level of governor circuit, and chip regulates voltage and the frequency of supply coil automatically according to the data that flow monitoring table feeds back.
Suppose that piston body 1 is the piston body with non-return valve function, piston body 1 is under coil produces the effect of electromagnetic excitation successively, start to advance, promote liquid or gas to travel forward, after moving to last coil, along with coil falls back excitation field successively simultaneously, piston body starts the movement that falls back, now owing to being positioned at the effect of cylinder body one end one-way valve, liquid is stopped in herein, only flows into the other of cylinder body by one-way valve cock body of living.After being backwards to the limit position of one-way valve piston body, an operation cycle of this pump terminates.
If changed into by piston body solid, and one-way valve rectification pipeline is installed at cylinder body two ends, then this pump is same to liquid or air work in the process of falling back, and promotes liquid and advances.But the program adds the complexity of pipeline, the volume of pump increases, and due to the use of multiple one-way valve, causes the reliability of pump to reduce.
