Problems solved by technology
[0004] However, in the above-mentioned vane water pump, when the transmission shaft rotates, the waterproof seal between the transmission shaft installation hole and the transmission shaft will rub against the transmission shaft. When there is continuous friction on the transmission shaft, the waterproof seal is easily damaged due to the lack of an effective heat dissipation structure, which greatly increases the maintenance cost of the water pump; at the same time, if the waterproof seal is not replaced in time, it is easy to cause water leakage in the water suction chamber and reduce the performance of the water pump

The invention discloses a blade water pump, which comprises a shell (1), wherein a water absorbing cavity (2) and a water pressurizing cavity (3) which are separated mutually are formed in the shell (1); a transmission shaft mounting hole (4) is formed on the water absorbing cavity (2); the water absorbing cavity (2) is in transmission connection with a transmission shaft through the transmission shaft mounting hole (4); and at least one turbulent flow tendon (5) is arranged in the water absorbing cavity (2). Therefore, water in the water absorbing cavity changes direction by impacting and contacting with the turbulent flow tendon in the operating process of the blade water pump, so that the water is concentrated at the position of a waterproof seal between the water absorbing cavity and the transmission shaft, the waterproof seal can better radiate, the service life of waterproof sealing elements is prolonged, and the maintenance cost of the water pump is reduced.
Description
technical field [0001] The invention relates to the technical field of fluid pumping equipment, in particular to a vane type water pump. Background technique [0002] With the development of my country's economic construction, various liquid pumping equipment, especially vane water pumps, are more and more widely used in various fields of industrial and agricultural production. [0003] The vane pump is a pumping device that uses the interaction between the vane and the liquid to transport the liquid. A typical vane-type water pump includes a housing, in which an impeller with blades is installed, and the impeller is fixedly connected to the drive shaft of the shaft coupling bearing through an interference fit, and the drive shaft is fixedly connected to the pulley, and the The power of the engine arranged outside the casing is transmitted to the impeller, and the water pumping function of the water pump is realized through the rotation of the impeller. In the vane water p...
