Environment-friendly energy-saving water pump for agricultural water conservancy projects

Abstract

The invention discloses an environment-friendly energy-saving water pump for agricultural water conservancy projects, and relates to the technical field of water pumps. The environment-friendly energy-saving water pump for the agricultural water conservancy projects comprises a base, wherein the top of the base is fixedly connected with a water pump shell and a water pump motor; a cabin door is arranged on the side wall of the water pump shell; an output shaft of the water pump motor is in driving connection with a transmission shaft; first rotating holes are formed in the inner walls of the two sides of the water pump shell; one end of the transmission shaft penetrates through one of the first rotating holes and is fixedly connected with a rotating cylinder; and multiple second rotating holes are evenly formed in the side wall of the rotating cylinder. According to the environment-friendly energy-saving water pump for the agricultural water conservancy projects provided by the invention, the cabin door can be opened before water pumping, a limiting sliding sleeve slides down from a rotary knob, the rotary knob is rotated to drive blades to rotate, and the angles of the blades are adjusted, so that the water pumping amount of the water pump is manually adjusted and controlled, and energy loss and abrasion of the water pump motor when the power of the water pump motor is adjusted are reduced; and after the adjustment is completed, the limiting sliding sleeve slides to the rotary knob again to limit the rotary knob, so that adjustment and control are completed.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to an environment-friendly and energy-saving water pump used in agricultural water conservancy projects. Background technique [0002] In agricultural water conservancy projects, water pumps are essential and important equipment. Water pumps refer to machinery that transports liquids or pressurizes liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used for The conveying liquid includes water, oil, acid and alkali liquid, emulsion, suspoemulsion and liquid metal, etc. It can also convey liquid, gas mixture and liquid containing suspended solids. Energy-saving water pump, as the name implies, is a water pump that can save energy consumption. Its own high-efficiency operation reduces energy consumption. [0003] The existing water pump has a simple structure. Usually, the driving...

Problems solved by technology

[0003] The existing water pump has a simple structure. Usually, the driving motor drives the impeller in the water pump to rotate at a high speed, forming a negative pressure in the cavity to pump water. If you want to change the working power of the water pump and adjust the water pumping volume of the water pump, you need to adjust the power of the motor. However, this method not only increases power consumption, does not meet the theme of environmental protection and energy saving, but also increases the wear and tear of the motor and reduces the service life of the motor. In order to solve the above problems, we propose an agricultural water conservancy Environmentally friendly and energy-saving pumps for engineering
