The invention discloses a water pump machine which comprises a pump shaft and a water inlet, wherein a cutter component is arranged in an inner chamber of the water inlet and comprises an outer cutter and an inner cutter both of which adopt a cylindrical structure; the inner cutter is sleeved with the outer cutter which is provided with a connection structure capable of being fixedly connected with the inner chamber of the water inlet; at least one first opening arranged oppositely to the water inlet is formed in the cylinder wall of the outer cutter, and a first cutting surface is arranged on the edge of the first opening; a plurality of second openings are formed in the cylinder wall of the inner cutter, a second cutting surface is arranged on the edge of each second opening and has an included angle with the first cutting surface; and a plurality of water penetrating holes are formed in one end of the inner cutter and fixedly connected to the pump shaft. During operation, the pump shaft drives the inner cutter to rotate at a high speed while the outer cutter is fixed to the water inlet, when sundries are contained in water, double-blade cutting surfaces formed by the combination of the first cutting surface and the second cutting surfaces can cut the sundries, so that the problem that the water pump machine is prone to sundry blockage is solved according to the scheme.
Description
technical field [0001] The invention relates to the technical field of water pumps, in particular to a water pump. Background technique [0002] A 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, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. Water pumps are often used in liquid transmission in petroleum, chemical, sewage treatment, construction and other industries. However, when the water contains a large amount of sundries or fibers, the water pump is easily blocked and stuck by the sundries during the water pumping process, and cannot continue to work, thus reducing the production efficiency. [0003] Therefore, how to solve the problem that the water pump is ea...
