Embodiment 1

[0030] This embodiment is a water hammer pump with drag reduction and vibration reduction, such as figure 1 shown. This embodiment includes: a power pipe 1, the power pipe is connected to the pump body 2, the pump body is connected to the elbow 3, and the bottom of the vertical water inlet pipe 10, the water inlet pipe is connected to the water delivery valve 9, the The water delivery valve is connected to the air tank 7, the air tank is connected to the water outlet pipe 8, the elbow is connected to the small end of the different-diameter pipe 4 with one end large and the other end small, and the large end of the different-diameter pipe Connected with the drain valve 6, the water outlet valve disc 902 of the water delivery valve is provided with a water outlet guide body 902 on the back water surface, and the water outlet guide body is fixedly connected with the water outlet valve disc, and the drain valve of the drain valve Discharge guide body 5 is provided on the facing ...

Embodiment 2

[0044] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment on the drainage guide body. The discharge guide body described in this embodiment is: the head of the water-facing surface is hemispherical ( image 3 ), drum-shaped cone ( Figure 5 ), drum-shaped round table ( figure 1 ), the rear part is in the shape of a frustum with a large front end and a small rear end.

[0045] The head of the water diversion body is a hemispherical streamline shape, which is often called a nose spherical shape in three-dimensional solids. The drum-shaped cone is a cone formed by the generatrix turning on an outwardly protruding curve, and similarly, the drum-shaped cone is a circular frustum formed by the generatrix turning on an outwardly convex curve.

Embodiment 3

[0047] This embodiment is an improvement of the second embodiment, and is a refinement of the second embodiment on the drainage guide body. The drainage diversion body described in this embodiment is hollow, and the head and tail of the drainage diversion body are provided with through holes for communication, and the diameter of the rear end face circle of the drainage diversion body is less than or equal to the drainage disc The diameter of the front face.

[0048] The tail of the diversion body described in this embodiment, that is, the back water surface can adopt a fully open type or a partially shielded type. The so-called open type means that the back surface of the diversion body is not covered, and the diversion body is a thin shell structure, such as figure 1 shown. figure 1 It is a so-called shielding type, that is, there is a perforated top cover on the water surface of the diversion body.

[0049] According to the size of the acting water head H, the size of ...

Abstract

The invention relates to a resistance and vibration reduction hydraulic ram pump. The resistance and vibration reduction hydraulic ram pump comprises a power pipe, the power pipe is connected with a pump body, the pump body is connected with the bottom of a bend and the bottom of a vertical water inlet pipe, the water inlet pipe is connected with a water conveying valve, the water conveying valve is connected with an air tank, the air tank is connected with a water outlet pipe, the bend is connected with the small end of a reducing pipe, the large end of the reducing pipe is connected with a drain valve, the back side of a water outlet valve clack of the water conveying valve is provided with a water outlet deflector, the upstream face of a drain valve clack of the drain valve is provided with a drain deflector, the back side of the drain valve clack is provided with a runner cone, the drain deflector is fixedly connected with the reducing pipe, and the runner cone is fixedly connected with the drain valve clack. The deflectors are arranged on two check valves of the hydraulic ram pump, so that the purposes of decreasing the resistance coefficient of the check valves, reducing the weight of the valve clacks and preventing the hydraulic ram pump from violent vibration and cavitation erosion are achieved, the service life of the hydraulic ram pump can be prolonged, the noise and vibration of the hydraulic ram pump are reduced remarkably, and efficiency of the hydraulic ram pump can be improved remarkably.

Description

technical field [0001] The invention relates to a drag-reducing and vibration-reducing water hammer pump, which is a hydraulic mechanical device and a device that uses the natural force of a water head to automatically pump water without using other energy sources. Background technique [0002] In the design and operation of the water hammer pump, the efficiency, vibration, cavitation, cavitation and noise of the water hammer pump must be considered. [0003] The efficiency of the water hammer pump is mainly related to the local resistance coefficient of the check valve. At present, the valve disc of the water hammer pump discharge valve generally adopts a simple disc type, which has a simple structure, but its hydraulic performance is poor. A vortex zone is formed, resulting in a large local drag coefficient and energy loss. According to the principle of hydraulics, if a proper diversion device is installed in the pump body to improve the flow state in the pump body and r...
