Example 1

A kind of drilling water pumping equipment, including diesel engine 1 and water pump 2, the water pump 2 chooses the three-cylinder water pump 2 of plunger type, drive through synchronizing wheel and hold-in range between water pump 2 and the diesel engine 1, install the three-way connecting pipe 4 on the water outlet end of the water pump 2, one end of the three-way connecting pipe 4 is communicated with the relief pipeline 6, one end is communicated with the vibration damper pipe 3 of the water pump, and install the main water-conveying ball valve 5 on this end; the vibration reduction pipe 3 of the water pump comprises a vertical pipe body 31 with a water inlet 32 and a water outlet 33, a water pipe 34 is arranged in the pipe body 31, the water pipe 34 and the pipe body 31 are coaxially arranged, one end of the water pipe 34 is fixedly arranged at the water outlet 33 of the pipe body 31 and communicated with the water outlet 33, the outer side of the end of the water pipe 34 is fixedly connected with the pipe body 31 to form a closed space, the other end of the water pipe 34 is blocked, a plurality of water holes 35 are arranged on the side surface of the water pipe 34, which is close to the blocked end, the water holes 35 are arranged at intervals of 90 degrees along the circumferential direction of the water pipe 34, each row of five water holes 35 are arranged, so that after water enters from the water inlet 32 of the pipe body 31, water can only flow into the water pipe 34 through the water holes 35 and flow out from the other end of the water pipe 34, namely the water outlet 33 of the pipe body 31, the outside sliding connection of water pipe 34 has the piston piece 36 that is used for shutoff water inlet 32, piston piece 36 is the ring form, the ring inboard of piston piece 36 hugs closely and sliding connection with water pipe 34, the ring outside of piston piece 36 hugs closely and sliding connection with body 31 inner wall, after rivers get into body 31, piston piece 36 keeps off the rivers check to the space of piston piece 36 near water inlet 32 one side, water pipe 34 shutoff one end department outwards protrudes, be used for restricting piston piece 63 and pass through, when piston piece 36 is retracted to water pipe 34 shutoff one end department under compression spring 37 effect, piston piece 36 remains in water pipe 34 shutoff one end, isolate water inlet 32 and through-hole 35, fixed mounting has compression spring 37 on the side of piston piece 36 kept away from water inlet 32, compression spring 37's the delivery port 33 department of body 31 is fixed in to the other end.

The water pump 2 is a plunger type three-cylinder water pump 2, the water delivery pressure is high, and accordingly, the water supply of the plunger type water pump 2 is not a continuous process, and is intermittent water supply, the intermittent water supply can enable the water pumping device to vibrate, the water delivery pressure of the plunger type three-cylinder water pump 2 is high, the vibration is large, the damage to equipment is also large, and the vibration is damped by installing the water pump damping pipe 3 at the water outlet end of the water pump 2. The vibration reduction pipe 3 of the water pump has two functions, one of the functions is that when water flows into the pipe body 31, the water flows preferentially impact the piston piece 36, the piston piece 36 enables the compression spring 37 to be compressed under the impact of the water flow, the spring is compressed and stores energy, the water flow is communicated with the water through hole 35 of the water through pipe 34 after the piston piece 36 is pushed away, as the water through hole 35 has limited water flow, only a part of the water flow enters the outside of the pipe body 31 of the water through pipe 34, the intermittent water supply of the plunger type three-cylinder water pump 2 enables the water flow to be intermittent after the water flow enters, when the water supply intermittent water does not impact the piston piece 36, the piston piece 36 pushes back under the pushing of the compression spring 37 for energy storage, the water flow between the water inlet 32 of the pipe body 31 and the piston piece 36 is extruded, the rest water flow continuously flows into the water through hole 35 until the next water supply is temporary, the piston piece 36 is compressed again, the reciprocating motion of the piston piece 36 is formed, and the impact force which originally causes vibration of the equipment to be absorbed and stored energy is used as extrusion water flow after the compression spring 37 absorbs energy, so that the vibration caused by the intermittent water supply is reduced; and the water flowing out through the water pipe 34 flows through the water through hole 35, the piston piece 36 and the compression spring 37 to form relatively stable liquid flow. Secondly, the vibration reduction pipe 3 of the water pump has the function of a one-way valve, when the water pump suddenly extinguishes or other abnormal conditions occur to stop water supply, the piston sheet 36 is pushed back to the water pipe 34 to block one end under the action of the compression spring 37, the water inlet 32 and the water through hole 35 are isolated, and water flow can be prevented from flowing backwards, so that the water pump is damaged.

The pressure relief pipeline 6 is provided with a bypass valve 8 and a pressure gauge 7 for delivering water to other places or relieving pressure; and secondly, as the water supply end point is generally higher, when the machine is stopped, the main water delivery ball valve 5 is turned off, so that the waste caused by the backflow of water on a pipeline can be avoided. When the engine is started, the bypass valve 8 is opened, the main water delivery ball valve 5 is closed, the diesel engine 1 is started first and then is communicated with the main water delivery pipeline, and the engine can be prevented from being started under load.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
