Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning machine pumps, and in particular relates to an automatic monitoring device for water flow of a pump. Background Art

[0002] The pump is an important structure of the car washing machine. Before leaving the factory, the pump needs to undergo a variety of tests to ensure its quality. Flow test is one part of the pump test. The flow test is used to test the water flow that the pump can pump per unit time under the working state, and can directly test and feedback the operating performance of the pump.

[0003] The traditional method of testing the water flow rate of a pump is to start the pump, let it work naturally, and then measure the water flow rate pumped out by the pump after counting the seconds. This testing method is very cumbersome and takes a long time to test a group of pumps. Because there are errors in counting the seconds and measuring the water volume that are difficult to eliminate, the test data is not accurate enough. At the same time, this testing method can only measure the water flow rate of the pump when it is in normal operation, and cannot measure the pumping effect of the pump under different working environments. Utility Model Content

[0006] Preferably, the sides of the water inlet joint and the water outlet joint are both provided with water outlets for docking with the pump joint.

[0007] Preferably, the pump fixing fixture is detachably connected.

[0008] Preferably, movable wheels are provided at the bottom of the detection machine.

[0009] Preferably, an air source device is provided inside the detection machine, and the air source device is connected to the pressure cylinder through an air pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] This technical solution uses an automatic clamping and fixing cylinder, measures the unit water flow rate through an electronic flow meter, and displays it on a display screen. The water flow detection of the pump is convenient and easy to operate. At the same time, the pressure control valve can be used to adjust the water flow of the pump under different water pressures, so that the water flow test effect of the pump is better.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Reference Figure 1 A pump water flow automatic monitoring device comprises a detection machine 1, on which a group of pump fixing tooling 4 is arranged, two groups of abutting cylinders are symmetrically arranged along the pump fixing tooling 4, and water inlet joints 5 and water outlet joints are respectively installed on the front ends of the two groups of abutting cylinders, a group of water inlet pipes 6 are connected to the top of the water inlet joint 5, and a group of water outlet pipes 8 are connected to the top of the water outlet joint, and electronic flow meters 9 and pressure control valves 10 are arranged on the water outlet pipes 8 in sequence, and a display screen 11 is also arranged on the detection machine 1, and the electronic flow meter 9 and the pressure control valve 10 are electrically connected to the display screen 11.

[0016] In view of the problems that the existing pump water flow test is cumbersome to operate and has large detection errors, this scheme proposes an automatic monitoring device for pump water flow. The device is equipped with a pump fixing tool 4 on the detection machine 1, and two groups of abutting cylinders are symmetrically arranged along the left and right sides of the pump fixing tool 4. The two groups of abutting cylinders are respectively connected to the water inlet pipe 6 and the water outlet pipe 8. When testing the water flow of the pump, the pump is first fixed on the pump fixing tool 4, and the cylinder is started. The two groups of cylinders drive the water inlet joint 5 and the water outlet joint to move inward respectively until the water inlet joint 5 and the water outlet joint are fixedly docked with the pump. Then, the pipe mouth of the water inlet pipe 6 is docked with a container filled with water, and the pump is started. The pump drives water to pass through the water inlet pipe 6, the pump and the water outlet pipe 8 in turn. The electronic flowmeter 9 on the water outlet pipe 8 directly measures the water flow of the pump. In this technical scheme, the pressure control valve 10 can also be adjusted to adjust the unit water flow of the pump under different water pressures, so that the pump water flow test effect is better.

[0017] Furthermore, the sides of the water inlet joint 5 and the water outlet joint are both provided with water outlets 12 for docking with the pump joint.

[0018] Through this technical solution, the water outlet 12 is connected to the joint of the pump machine, and the shapes of the two are adapted. Under the force of the abutting cylinder, the water outlet 12 and the pump machine are tightly fitted, thereby achieving sealing; on the water inlet interface, the water outlet 12 is connected to the water inlet pipe 6, and the water flows in from the water inlet pipe 6 and enters the pump machine from the water outlet 12. On the water outlet interface 7, the water outlet 12 is also connected to the water outlet pipe 8, and the water flows into the water outlet 12 from the pump machine, and is finally discharged from the water outlet pipe 8.

[0019] Furthermore, the pump fixing fixture 4 is detachably connected.

[0020] Through this technical solution, the pump fixing fixture 4 can be disassembled to facilitate installation and replacement, thereby adapting to the testing of different models of pumps.

[0021] Furthermore, movable wheels 2 are provided at the bottom of the detection machine 1 .

[0022] The movable wheels 2 of the detection machine 1 are used to drive the detection machine 1 to move freely, so as to facilitate the transportation of the equipment.

[0023] Furthermore, an air source device is provided inside the detection machine 1 , and the air source device is connected to the pressure cylinder 3 through an air pipe.

[0024] Working principle: The first step is to fix the pump on the pump fixing tooling 4, start the cylinder, and the two groups of cylinders drive the water inlet joint 5 and the water outlet joint to move inward respectively, until the water inlet joint 5 and the water outlet joint are fixedly docked with the pump, completing the clamping and fixing of the pump; the second step is to dock the pipe mouth of the water inlet pipe 6 with the container filled with water, start the pump, and the pump drives the water to pass through the water inlet pipe 6, the pump and the water outlet pipe 8 in turn. The electronic flowmeter 9 on the water outlet pipe 8 directly measures the water flow of the pump; the third step is to repeat the test, adjust the pressure control valve 10, and measure the water flow data of the pump under no water pressure.
