Abstract

The invention discloses a pumping and pressing type water pump comprising a water pump shell. A motor box is fixedly installed on one side of the inner wall of the water pump shell. A motor is fixedly installed in the motor box. An output shaft of the motor penetrates out of the motor box and is fixedly connected with the position of the axis of a gear. Clamping teeth of the gear are engaged with clamping teeth of a rack. The side, away from the clamping teeth, of the rack is fixedly connected with one side of a movable rod. The movable rod is made to move up and down through cooperation of the motor, the gear and the rack. By means of up-down movement of the movable rod, a first piston is made to move up and down in a cylinder to compress air in the compression cylinder. By compressing the air in the compression cylinder, a movable block is made to move in an air pressure chamber. The movable block moves to drive a second piston to move. By means of movement of the second piston, water suction and water drainage are conducted. Only the second piston makes contact with water in the whole working process, key parts of the water pump are protected against rusting, and the service life of the water pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of fluid transportation, in particular to a pumping type water pump. Background technique [0002] A water pump is a machine that transports or pressurizes a liquid. 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 to transport liquids including water, oil, acid and alkali, emulsions, and suspoemulsions. It can also transport liquid, gas mixture and liquid containing suspended solids, but most of the water pumps on the market now work in a liquid environment for a long time, and the impeller will be damaged after a long time, affecting Pump work and service life of the pump. Contents of the invention [0003] The purpose of the present invention is to provide a pumping type water pump, which has the advantage of long service life, and solves the problem that most of the water pumps on the market work in the...
