Dual pumping fluid pump

Abstract

The present invention relates to a dual pumping fluid pump which significantly reduces vibration and noise generation in the following manner. When a cam installed on a rotating shaft of a single electric motor is rotated, a pair of first and second diaphragms installed in connection to an eccentric shaft portion formed on both the left and right sides of the cam alternatingly rise and descend inopposite directions and cause first and second intake check valves and first and second discharge check valves provided on a fluid passage box integrally and connectedly installed on the top surface of a pump housing to open or close first and second intake holes and first and second discharge holes to admit fluid through a fluid inlet and simultaneously discharge fluid through a fluid outlet, sothat the simultaneous effects of the intake pressure and discharge pressure of fluid causes pressure balancing to occur. In addition, the present invention has tensioning spaces further formed at positions corresponding to a discharge check valve installation chamber and an intake check valve installation chamber at the undersurface of an upper cam, such that when a discharge pressure and an intake pressure of fluid are formed at the discharge check valve installation chamber and the intake check valve installation chamber, a lower pad is resiliently deformed upwardly and downwardly to mitigate pressure and more effectively prevent pulsation.

Description

technical field [0001] The invention relates to a double-pump fluid pump. Specifically, with the rotation of a motor, a pair of first and second diaphragms arranged on the pump casing are alternately raised and lowered in opposite directions, and then pass through the top of the pump casing. The first and second suction check valves and the first and second discharge check valves provided on the integrated fluid channel box open or seal the first and second suction holes and the first and second discharge holes to allow fluid to pass through A double-pump fluid pump that attenuates vibrations and noises significantly through the pressure offset phenomenon that occurs due to the simultaneous action of fluid suction pressure and discharge pressure, as the fluid flows in from the fluid discharge port. Background technique [0002] A fluid pump using a diaphragm is a device that converts the motor's rotational motion into a linear reciprocating motion of the diaphragm through a ...

Problems solved by technology

[0014] However, if two or more pumps are connected in parallel, compared with the effect, the required installation cost is more invested, and the installation work is not easy when the air chamber is installed in the middle of the fluid line, and the pump connector and the fluid line are tubes. type will be difficult to set up

[0015] The connection part of the pump is frequently damaged due to the vibration of the air chamber during the operation, so the pulsation of the discharge flow itself in the pump is not completely eliminated, resulting in relatively large vibration and noise
