The invention discloses a rotating baffle double-blade wheel volume pump. The rotating baffle double-blade wheel volume pump comprises a pump shell, wherein a main rotating shaft, a first auxiliary rotating shaft and a second auxiliary rotating shaft are arranged in the pump shell, the first auxiliary rotating shaft and the second auxiliary rotating shaft are located on the two sides of the main rotating shaft, the main rotating shaft is provided with a baffle main rotor, the first auxiliary rotating shaft is provided with a first blade rotor, the second auxiliary rotating shaft is provided with a second blade rotor, the first blade rotor and the second blade rotor are always in contact with the inner wall of the pump shell during rotation, and meanwhile, the first blade rotor and the second blade rotor are also in contact with the outer peripheral wall of the baffle main rotor. According to the rotating baffle double-blade wheel volume pump, pump blades and baffles are fixedly connected, so that the durability and the anti-pollution performance are better than those of a universal blade pump; in addition, a gear used for interacting and transmitting torque is placed in a non-conveying liquid cavity, and a lubricating fluid can be injected, so that the mechanical performance is improved; and small mutual friction is generated in the transmission rotation meshing process, the pump blade wheel are only provided with two blades, and the pulsation frequency and fluctuation are smaller than those of the universal blade pump and a gear pump.
Description
technical field [0001] The invention relates to the technical field of liquid conveying equipment, in particular to a volumetric pump with rotating baffles and double blade wheels. Background technique [0002] A positive displacement gear pump is a pump that uses changes in the pressure in the pump cylinder to deliver liquid. However, the actual working conditions are far from ideal. Due to the relatively thick pipes, there is a certain distance between the positive displacement pump and the tank. Every time, the pump needs to be turned on in advance to discharge the air. The liquid can only be pumped out after the vacuum degree in the pipe reaches a certain limit. The radial force is unbalanced, the flow pulsation is large, the noise is large, the efficiency is low, the interchangeability of parts is poor, and it is not easy to repair after wear and tear, so it cannot be used as a variable displacement pump. And there are oil leakage, trapped oil, and uneven force. Howev...
