Description

Technical Field

[0001] This utility model relates to the field of micro flow meter technology, and in particular to a micro electromagnetic pump flow testing device. Background Technology

[0002] An electromagnetic pump is a pump that allows a current-carrying fluid in a magnetic field to flow in a specific direction under the influence of electromagnetic force. It utilizes the interaction between a magnetic field and the current in a conductive fluid to create a pressure gradient in the fluid, thus propelling the fluid. Many everyday products use miniature electromagnetic pumps, including coffee makers and garment steamers. Miniature electromagnetic pumps require rubber O-rings for sealing, and the lifespan of these O-rings directly affects the pump's flow rate. There is no dedicated equipment on the market for testing the flow rate of electromagnetic pumps, especially since the flow rate is extremely small. Furthermore, flow meters for such small flow rates require specially developed and expensive individual flow meters. Testing the lifespan of electromagnetic pumps would require multiple pumps to be tested simultaneously, each requiring a flow meter, which, at several thousand yuan per meter, results in a very high total cost. Therefore, providing a simple, low-cost, and highly reliable electromagnetic pump flow testing device is a crucial technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an electromagnetic pump flow testing fixture that is simple in structure, low in cost, and highly reliable.

[0004] To solve the above technical problems, this utility model provides a micro electromagnetic pump 4-station water pumping metering life test device. The electromagnetic pump 4-station water pumping metering life test device is characterized by being divided into 4 sets of electromagnetic pump water pumping mechanisms, including a rotatable water cup (4). The rotatable water cup (4) is driven by a rotating cylinder (7) to achieve the action of pouring water. The electromagnetic pump (11) is fixed to the top horizontal plate (2) by bolts inserted into the mounting holes outside the pump body and nuts. When the electromagnetic pump (11) pumps water, the water flows out to the water cup (4) through the hole of the hose fixing seat (3) via the hose. When the water level reaches the specified position, the liquid level sensor (13) sends a signal to the PLC to control the solenoid valve (1), and then controls the rotary cylinder (7) to drive the water cup (4) to rotate to pour water and reset. After the PLC times the water level, the electromagnetic pump (11) is started to pump water, and the cycle repeats. Furthermore, the equipment includes 4 sets of electromagnetic pump testing mechanisms of the same specifications. Each set includes an electromagnetic pump, a solenoid valve, a liquid level sensor, a rotary cylinder, a water cup and a water cup fixing seat, etc. Attached Figure Description

Detailed Implementation

[0006] Example 1 As shown in Figures 1 and 2, since the four electromagnetic pump water metering mechanisms of the tooling are all of the same action structure, the quick connector insertion and removal test tooling of this embodiment is described here as a set of actions and structures, including a rotatable water cup (4), a fixed electromagnetic pump (11), a fixed liquid level sensor (13), and a hose fixing seat (3); the water cup (4) is fixed on the cup fixing seat (6), and the cup handle is fixed by the cup handle fixing plate (5); the cup fixing seat (6) is fixed on the rotary cylinder (7) by screws, and the rotary cylinder is fixed on the cylinder mounting plate (10); the fixed electromagnetic pump (11) It is installed on the edge of the top horizontal plate (2); the fixed liquid level sensor (13) is fixed on the sensor mounting base (12), and the sensor mounting base (12) is fixed on the top horizontal plate (2) by screws.

[0007] Furthermore, the electromagnetic pump (11) is fixed to the top horizontal plate (2) by bolts inserted into the mounting holes outside the pump body and nuts. After the electromagnetic pump (11) pumps water, the water flows out to the water cup (4) through the hole of the hose fixing seat (3) via the hose. When the water level reaches the specified position, the liquid level sensor (13) sends a signal to the PLC to control the solenoid valve (1) to control the rotary cylinder (7) to drive the water cup (4) to rotate to pour water and reset. After the PLC times the time, the electromagnetic pump (11) is started to pump water, and the cycle repeats.
