Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing:
[0013] Such as figure 1 combine figure 2 As shown, the multi-head anti-corrosion screw pump with equal wall thickness includes a stator housing 3 with a rubber layer 2 inside and a hollow rotor 1. There is a rubber layer 2 in the stator housing 3, and a hollow rotor 1 is built in the rubber layer 2. The hollow rotor 1 is helical. The number of heads is 1, and the inner hole of the hollow rotor 1 is processed into a shape corresponding to the shape by using a special CNC machine tool, so that the wall thickness of the hollow rotor 1 is equal; the number of spiral heads of the stator housing 3 that matches the hollow rotor 1 is 2, using a special numerical control machine tool, process the inner hole of the stator housing 3 into a shape corresponding to the shape, so that the wall thickness of the stator housing 3 is equal, and cast a rubber layer 2 of equal thickness along...
