Problems solved by technology
[0002] Screw rotors are widely used in aviation, aerospace, ocean engineering, and basic industries of national production. Due to the complexity of the tooth surface configuration of screw rotors, the gap control of screw rotors has greater uncertainty and uncertainty than other types of positive displacement pumps. Unevenness seriously affects the volumetric efficiency and service life of the screw pump. If the gap is too large, the internal leakage of the pump will increase and the volumetric efficiency will decrease; if the gap is too small, the friction between the moving parts will increase and the service life will be reduced.

Description
technical field [0001] The invention belongs to the technical field of screw detection, and relates to an auxiliary device for screw rotor gap detection. Background technique [0002] Screw rotors are widely used in aviation, aerospace, ocean engineering, and basic industries of national production. Due to the complexity of the tooth surface configuration of screw rotors, the gap control of screw rotors has greater uncertainty and uncertainty than other types of positive displacement pumps. The unevenness seriously affects the volumetric efficiency and service life of the screw pump. If the clearance is too large, the internal leakage of the pump will increase and the volumetric efficiency will decrease; if the clearance is too small, the friction between the moving parts will increase and the service life will be reduced. [0003] After searching, for example, the Chinese patent literature discloses a method for determining the pump gap value of an electric submersible scre...
