DP Miniature diaphragm ┃ electric diaphragm pump

■ DP Miniature diaphragm pump Product Overview: DP-resistant valve production Miniature electric diaphragm pump is (voltage of 12V, 24V motors) powered drive unit with miniature DC motors, drive internal mechanical eccentric eccentric motion by eccentric motion drive internal diaphragm reciprocates. Thus fixed volume pump chamber is compressed air (compressed exhaust port is closed, the exhaust port open form a slight positive pressure), stretching (the exhaust port is closed when the compression, sucking mouth open negative pressure), the pumping air intakes and external atmospheric pressure difference, at a pressure difference, the gas pressure (suction) into the pump chamber, and discharged from the exhaust port. ■ DP Miniature diaphragm pumps Technical parameters: ● voltage: 12 ~ 24VDC ● Maximum current: 1 ~ 7A ● Maximum flow rate: 1 ~ 12L / min ● Speed: 470 ~ 1300 r / min ● maximum pressure: 0.24 ~ 0.9Mpa ● Suction Cheng: 5m ● Tap: --- PSI ● Input power: 10 ~ 40W ● Pump Material: FRPP ● Diaphragm material: plastic EPDM, NBR ■ DP Miniature diaphragm pump works: DP type The first micro-diaphragm pump operating modes: circular motion of the motor, by mechanical means inside the pump diaphragm to do a reciprocating motion, thereby compressing, stretching a negative pressure air pump chamber, a pressure at the suction mouth with the outside atmospheric pressure the difference in pressure difference, the gas suction pump chamber, and discharged from the exhaust port. DP Miniature diaphragm second mode of operation: miniature diaphragm pump is the use of screw rotation to suction fluid. Miniature diaphragm pumps for the active screw screw in the middle, motivated by the original rotation, both sides of the screw is driven screw with the active screw for reverse rotation. Main, driven screw threads are double threads. Due to the close intermeshing with each screw and screw and liner tube wall between the inlet and outlet port miniature diaphragm pumps, it will be divided into one or more of the sealed space. With the rotation and intermeshing screws, which are sealed space in the suction side of the pump evolving, the suction chamber in which liquid is sealed, and from the suction chamber along the screw axis continuously push to move the discharge end, it will be closed in the space continuous discharge of liquid, like the case of a nut rotation in the thread that is constantly moving forward, this is the basic principle of micro diaphragm pumps. ■ DP Miniature diaphragm Images:
