Technical Field

[0001] The invention relates to an exhaust device, and more particularly to a water exhaust device for a drilling pump. Background Art

[0002] At present, the existing low-pressure side water supply structure of the circulating fluid is composed of a gate valve and a fluid manifold in series. One end of the gate valve is connected to the fluid collection tank, and the other end is connected to one end of the fluid manifold. The other end of the fluid manifold is connected to the working machinery to form a circulating fluid low-pressure side water supply pipeline. Due to the high density of the fluid, poor fluidity, long transmission distance, and disturbance of the agitator in the tank, the gas on the low-pressure side of the fluid gathers and the water supply is poor, which affects the relevant setting parameters on the high-pressure side of the fluid and causes a slow production rhythm. In addition, the low-pressure side transmission pipeline of the fluid needs to be cleaned frequently. In severe cases, an auxiliary pump needs to be added to provide the fluid supply on the low-pressure side. Summary of the invention

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the water supply and exhaust device for a drilling pump of the present invention comprises a liquid collecting tank 1, a fluid pipe 7 and an exhaust pipe 5. The bottom of the liquid collecting tank 1 is connected to the fluid pipe 7. The exhaust pipe 5 is vertically arranged on the fluid pipe 7. The end of the fluid pipe 7 is connected to the water supply pipe 8 on the low-pressure side of the circulating fluid. The liquid collecting tank 1, the fluid pipe 7 and the exhaust pipe 5 are arranged in a U shape as a whole. A first gate valve 2 is arranged at the outlet of the liquid collecting tank 1, and the first gate valve 2 is connected to the fluid pipe 7. A second gate valve 6 is arranged at the top of the exhaust pipe 5. A flange 4 is arranged at the lower end of the exhaust pipe 5. A filter screen 3 is arranged in the fluid pipe 7. The lower end of the exhaust pipe 5 is connected to the filter screen 3 through the flange 4.

[0017] In the preferred embodiment of the present invention, a flange 4, an exhaust pipe 5 tank and a second gate valve 6 are included. The exhaust system does not require power. The exhaust pipe 5 is installed at the filter screen 3 on the drilling pump. By using the U-tube principle, the gas accumulated in the water supply pipeline can be promptly removed without affecting the flow and fluidity of the low-pressure side of the pump, thereby solving the problem of gas accumulation in the pipeline on the low-pressure side of the fluid, solving the problem of poor water supply on the low-pressure side of the drilling pump, stabilizing the design parameters of the high-pressure side of the fluid, and improving the drilling time efficiency.
