Embodiment 1

[0016] This embodiment is a large water hammer pump, 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 4, and the bottom of the vertical water inlet pipe 3, the water inlet pipe is connected to the water delivery valve 7, the The water delivery valve is connected to the air tank 8, and the air tank is connected to the water outlet pipe 9. The cross-sectional area of ​​the power pipe is equal to that of the pump body and the elbow, and the elbow has one end larger and the other end smaller. The small end of the reducing pipe 5 is connected, and the large end of the reducing pipe is connected with the drain valve 6.

[0017] The power pipe described in this embodiment introduces the upstream water head into the water pump and provides the power of the water pump. Therefore, the power pipe has the pressure provided by the water head.

[0018] The pump body is a section of str...

Embodiment 2

[0050] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment on the reducer. The shape of the reducer described in this embodiment on the vertical plane passing through the central axis of rotation is frusto-conical.

[0051] The reducer is a pipe with a variable cross-section. The reducer described in this embodiment is a gradually expanding reducer, that is, the cross-sectional area of ​​the pipe gradually increases to form a trumpet shape or a truncated cone shape, which passes through the center line of rotation. The cross-sectional shape in the vertical plane is frusto-conical. The two symmetrical oblique lines of the truncated cone can be straight or curved. If the slope of the truncated cone is an inwardly curved curve, the shape of revolution is a flare. If the slope of the frustum of the cone is a straight line, the revolution shape is a frustum of a cone, such as figure 1 shown.

Embodiment 3

[0053] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment on the reducer. The shape of the reducer described in this embodiment on a vertical plane passing through the central axis of rotation is a rectangle.

[0054] The reducer described in this embodiment is a sudden change, that is, the diameter of the pipe changes from small to large in a very short distance, and its shape on the vertical plane passing through the center line of rotation is open at one end and has an end face at the other end. Cylindrical, the end face resembles a step. The connection between the end face and the cylinder can be a relatively sharp right angle, or a relatively large arc transition.

Abstract

The invention relates to a hydraulic ram pump which comprises a power pipe. The power pipe is connected with a pump body, the pump body is connected with the bottom of a bent pipe 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 section area of the power pipe is equal to that of the pump body and that of the bent pipe, the bent pipe is connected with the small end of a tapered pipe, the tapered pipe is provided with the large end and the small end, and the large end of the tapered pipe is connected with a drainage valve. The tapered pipe is arranged on the position of the drainage valve, the tapered pipe, the bent pipe and the drainage valve are integrated, and water head loss can be reduced. Compared with a traditional hydraulic ram pump, efficiency of the hydraulic ram pump is improved, the lift of the hydraulic ram pump is increased, and the size of the hydraulic ram pump is reduced. Due to reduction of the size of the hydraulic ram pump, on one hand, materials used for manufacturing the hydraulic ram pump is saved; on the other hand, engineering quantity for installation of the hydraulic ram pump is saved. Reduction of the engineering quantity is very important to engineering constructions such as pumped storage or water transfer projects and other large hydraulic ram pump stations, and earthwork and installation cost can be greatly reduced.

Description

technical field [0001] The invention relates to a water hammer pump, which is an automatic water pumping device, and is a device that uses the natural force of a water head to automatically pump water without other energy sources. Background technique [0002] With the progress of society and the understanding of the limitations of petrochemical energy applications, people pay more and more attention to various equipment that directly converts natural forces into power. As a pumping equipment that can operate efficiently without secondary energy such as electricity, the water hammer pump is an ideal natural force conversion equipment. However, due to various restrictions, the power of the traditional water hammer pump cannot be too large, so it can only be used in the occasion of pumping water in agricultural fields. Theoretically speaking, if a high-power water hammer pump is used to raise the water flow with an ultra-low water head (water head less than 5 meters) to a hei...
