Problems solved by technology

In the past, the method of inspecting the repaired sand discharge pump was to put the sand discharge pump in the water tank to run, and check whether the maintenance quality was checked by observing whether the water was supplied. However, this inspection can only determine whether the sand discharge pump can work normally, and cannot specifically measure it. Whether some important working parameters of the sand discharge pump can meet the requirements will lead to unstable performance of underground drainage equipment in the long run, which will bring many unsafe factors

Embodiment 1

[0023] Such as figure 1 As shown, the device is mainly composed of the following parts: liquid circulation part, hydraulic lifting part, electrical control part. The liquid circulation part is mainly composed of the following parts: water inlet pipeline 1, pressure gauge 3, flow meter 4, stop valve 6, fixed leg 11, water return port 12, and water inlet connecting flange 13. The hydraulic lifting part is mainly composed of the following parts: a support frame 2, a hydraulic pump station 8, an oil circuit connecting pipe 9, a lifting hydraulic cylinder 10 and a reversing valve controlled by a reversing valve switch 7. The electrical control part is mainly composed of the electric control panel 5 and other necessary circuit parts.

[0024] The main body of the liquid circulation part is a water inlet pipeline 1, and one end of the water inlet pipeline 1 is a water inlet connection flange 13, which is used for connection with the sand discharge pump to be tested. In the middle o...

Embodiment 2

[0034] Such as image 3 Shown is a 660V power circuit, which is composed of three live wires L1, L2, and L3. The power switch KA1 is connected in series to the three live wires L1, L2, and L3 to realize closing and disconnecting of the power circuit. The input end of the transformer B1 is connected to the live wires L2 and L3. Transformer B1 reduces the voltage to 36V, and a control loop is connected in parallel at both ends of the 36V power supply.

[0035] The control loop is mainly composed of contactor coil C1, stop button TA1, start button QA1 and the normally open contact of contactor C1. The contactor coil C1, stop button TA1 and start button QA1 are connected in series and parallel to both ends of the 36V power supply. The normally open contact C1-4 of the contactor C1 is connected in parallel with both ends of the start button QA1.

[0036] The three live wires L1, L2, and L3 in the power circuit are respectively connected in series with the normally open contacts C...

Abstract

The invention provides a performance parameter measuring device for a sand draining pump, and belongs to the technical field of measuring apparatus of coal mine underground drainage facilities. The performance parameter measuring device comprises a water inlet pipeline (1), a pressure gauge (3), a flow meter (4) and a stop valve (6), wherein the water inlet pipeline (1) is arranged on a supporting frame (2); the pressure gauge, the flow meter and the stop valve are arranged on the water inlet pipeline (1); a lifting hydraulic cylinder (10) is arranged on the supporting frame (2); one end of an oil-way connecting pipe (9) is connected with the lifting hydraulic cylinder (10), while the other end of the oil-way connecting pipe (9) is connected with a reversing valve by an oil pump in a hydraulic pump station (8); the water inlet pipeline (1) is driven to raise and fall by a valve core of the lifting hydraulic cylinder (10); and an electric control plate (5) controls the hydraulic pump station (8) by a power lead; and an electric appliance control loop is used for realizing control by means of the electric control plate (5). The performance parameter measuring device can be used for simulating the loading running in a job site and and accurately measuring whether the important parameter of the sand draining pump which is repaired completely meets an appointed requirement; in addition, the performance parameter measuring device has the following advantages of simple structure and convenience in operation.

Description

technical field [0001] A device for measuring performance parameters of a sand discharge pump belongs to the technical field of detection equipment for underground drainage facilities in coal mines. Background technique [0002] Sand discharge pumps are one of the most widely used and effective mine drainage facilities. A safe and reliable drainage system is an important guarantee for mine safety production. With the development of modern mines, its reliability, stability and safety have become the research goals of scientific and technological workers. A large number of sand pumps are needed to drain underground mines, so the maintenance of sand pumps is a very important task. The maintenance quality of sand discharge pump is an extremely difficult problem faced by underground drainage. In the past, the method of inspecting the repaired sand discharge pump was to put the sand discharge pump in the water tank to run, and check whether the maintenance quality was checked b...
