Description

Technical Field

[0001] The present invention relates to the technical field of pump bodies, and specifically relates to a device and method for improving pump efficiency. Background Art

[0002] Currently, in a pump body, the input hydraulic power is used to do work on the liquid passing through the impeller because the pressure of the liquid at the outlet of the impeller is higher than the inlet pressure. The pressure difference between the outlet and the inlet causes a part of the liquid passing through the impeller to flow back from the pump cavity through the gap between the pump body and the impeller gland to the impeller inlet. Therefore, the theoretical flow rate through the impeller is not all delivered to the pump outlet.

[0003] During the process of discharging water into the pipeline by the existing pump body, due to the influence of the friction force of the pipeline inner wall, the water flow velocity decays relatively fast, which reduces the pumping efficiency of the pump body to a certain extent. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and method for improving pump efficiency, aiming to solve the problem of low pumping efficiency when using the existing device and method for improving pump efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solution. A device for improving pump efficiency includes a liquid pump and a liquid discharge pipe, and further includes a connecting pipe assembly, an acceleration assembly, and a gas compression assembly. One end of the liquid discharge pipe is installed at the position of the liquid pump outlet. The acceleration assembly is installed between the liquid discharge pipe and the connecting pipe assembly. The connecting pipe assembly includes a pipe body, a fixed housing, and a transmission part. The transmission part is installed on the surface of the fixed housing. The fixed housing is fixedly connected to the pipe body at one end close to the liquid discharge pipe. The fixed housing is connected to the end face of the liquid discharge pipe through a fastener. An exhaust port is provided at one end of the fixed housing close to the inner wall of the pipe body. The included angle between the axis of the exhaust port and the inner wall of the pipe body is 15°, 30°, or 45°. A turbine rotatably connected between the pipe body and the liquid discharge pipe is arranged in the acceleration assembly. The gas compression assembly includes a pressurizing part and a piston part. The pressurizing part is movably connected to the piston part. The piston part is slidably connected to the inner wall of the fixed housing. The pressurizing part is movably connected to the transmission part. The transmission part is meshed with the acceleration assembly.

[0006] As a further solution of the present invention, the acceleration assembly further includes a driving motor, a driving gear, and a driven gear. The driving gear is connected to the driving motor through a driving shaft. The driven gear is connected between the pipe body and the liquid discharge pipe. The cross-section of the driven gear is a ring. The driving gear is meshed with the outer side of the driven gear. The outer side of the turbine is fixedly connected to the inner side of the driven gear.

[0007] As a further solution of the present invention, the transmission part includes a transmission gear, a transmission shaft and a first synchronous pulley. The transmission gear and the first synchronous pulley are both fixedly sleeved on the transmission shaft. The two ends of the transmission shaft are connected between the fixed housing and the drain pipe. The driven gear is meshed and connected with the transmission gear, and the pressurizing part is movably connected with the first synchronous pulley.

[0008] As a further solution of the present invention, the pressurizing part includes a rotating rod, a second synchronous pulley, a synchronous belt, a rotating housing, a pulley, a connecting frame and a sliding rod. One end of the rotating rod is installed on the end face of the drain pipe, and the other end is installed at an eccentric position on the side wall of the rotating housing. The second synchronous pulley is fixedly sleeved on the rotating rod. The synchronous belt is connected between the first synchronous pulley and the second synchronous pulley. The pulley is installed below the connecting frame. The upper end of the sliding rod is connected above the connecting frame, and the lower end of the sliding rod is connected with the piston part. The pulley is slidably connected with the inner wall of the rotating housing.

[0009] As a further solution of the present invention, the piston part includes an arc-shaped housing, an elastic strip and a return spring. The number of the first arc-shaped housing and the elastic strip is several. Several arc-shaped housings and elastic strips are combined into a circular whole. Both ends of the elastic strip are slidably connected in two adjacent arc-shaped housings. The return spring is located in the arc-shaped housing. The arc-shaped housing is connected between two elastic strips. The side walls of the arc-shaped housing and the elastic strip are both slidably connected with the inner wall of the fixed housing.

[0010] As a further solution of the present invention, a first one-way valve is arranged above the fixed housing, and second one-way valves are arranged on the surfaces of the arc-shaped housing and the elastic strip.

[0011] As a further solution of the present invention, guide rails are opened on the side wall of the fixed housing and the end face of the drain pipe. Sealing rings are fixedly connected to two opposite surfaces of the driven gear, and the sealing rings are rotatably connected in the guide rails.

[0012] A method for improving the efficiency of a pump includes the following steps:

[0013] Step 1: After the liquid pump is started, it first discharges water into the drain pipe. When the water in the drain pipe flows through the turbine, the acceleration component drives the turbine to rotate at a high speed. The turbine rotating at a high speed can quickly discharge the water in the drain pipe into the pipe body by generating a pressure difference, realizing the function of quickly discharging the water in the liquid pump into the pipe body and improving the pumping efficiency of the liquid pump.

[0014] Step 2: The acceleration component also drives the pressurization component to perform eccentric rotational motion through the transmission part. The pressurization component performing eccentric rotational motion can drive the piston component to perform reciprocating linear motion within the fixed housing. The piston component performing reciprocating linear motion first inhales external air into the fixed housing, and then compresses it and discharges it to the inner wall of the pipeline body through the inclined exhaust port. The airflow evenly covering the inner wall of the pipeline body can, on the one hand, reduce the friction between water and the inner wall of the pipeline body, and on the other hand, the driving force generated by the airflow can accelerate the flow rate of water, so that water can flow rapidly within the pipeline body, further improving the pumping efficiency of the liquid pump.

[0015] In summary, the beneficial effects of the present invention are as follows: The acceleration component drives the turbine to rotate at high speed. The turbine rotating at high speed can rapidly drain the water in the liquid discharge pipe into the pipeline body by generating a pressure difference. The acceleration component also drives the pressurization component to perform eccentric rotational motion through the transmission part. The pressurization component performing eccentric rotational motion can drive the piston component to perform reciprocating linear motion within the fixed housing. The piston component performing reciprocating linear motion discharges the compressed gas to the inner wall of the pipeline body through the inclined exhaust port. The airflow evenly covering the inner wall of the pipeline body can, on the one hand, reduce the friction between water and the inner wall of the pipeline body, and on the other hand, the driving force generated by the airflow can accelerate the flow rate of water, so that water can flow rapidly within the pipeline body, further improving the pumping efficiency of the liquid pump.
