Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model provides a kind of submersible type membrane pump, including upper shell 1 and lower house 2, upper shell
Inside being provided with direct current generator 103, direct current generator is connected, bottom lower house with the pump housing 203 being positioned at lower house by connecting plate 104
Being provided with water suction fence, direct current generator output shaft is provided with eccentric, eccentric is connected with bearing fit, drivening rod 105 He
Diaphragm moves up and down, and after water inlet connection liquid, switches on power, and direct current generator operates, and motor output shaft is provided with eccentric,
Equipped with bearing on eccentric, owing to eccentric and direct current generator be not concentric, there is an offset, cause bearing to rotate with motor
Time swing up and down, thus drivening rod and diaphragm move up and down so that the volume of working chamber is constantly reducing and expanding, during expansion
Working chamber produces negative pressure, the soft check valve wicking of water intaking valve side is opened, and water is inhaled into by intake antrum 201 from water suction fence mouth 202
Working chamber, during compression, fluid pressure raises, and is backed down by soft for water chamber side nonreturn valve core, and liquid is pressed into water chamber 204, liquid edge
Water channel to eject from exhalant canal 108.
The side of lower house 2 straight up be provided with exhalant canal, the water chamber 204 of the pump housing connects with exhalant canal 108,
Water chamber 204 is provided with pressure control device, pressure control device and direct current generator with the horizontal side of the junction of exhalant canal
103 control to connect.
Pressure control device includes the pressure regulation cushion 3 that the water chamber with the pump housing is tightly connected, and pressure regulation cushion 3 is provided with rear
Movable spring housing 302, the switch contact 303 that spring housing controls direct current generator opening and closing with rear is detachably connectable, switch
The binding post at connection rear, contact.The contact of spring housing and switch contact and separate work stopping and the work controlling direct current generator
Make.
In order to reduce volume, lowering the center of gravity, water chamber 204 is horizontally disposed with, and pressure regulation cushion is vertically arranged.
The middle part of spring housing 302 is provided with the regulator bolts 305 of regulation spring pressure, regulates spring by elasticity bolt
Compression degree and then adjustment operating pressure.The switch protecting cover 307 of protected pressure spring it is flexibly connected outside regulator bolts.
Upper shell top is provided with wire guide, and wire guide is cone surface shape, is provided with cone seal plug 102 in wire guide, with
The power lead that direct current generator connects enters in the cavity of upper shell from the endoporus of cone seal plug, Wire sheath 101 and cone
