How to assemble the vane pump of injection molding machine?
Clean all parts carefully and remove burrs and dirt rust spots on the parts.
In order to measure the width and size of the upper groove of the blade and rotor, the mating clearance of the two parts should be within 0.013 ~ 0.018mm.The blade should slide flexibly in the groove.
To select a set of blades, the height should be close to each other, and the unequal size error should be within the range of 0.008mm.
The blades installed in the tank shall be slightly lower in height than the depth of the tank, with an error of about 0.005mm.
The rotor and blade should be loaded into the stator in the direction of original disassembly.
The clearance between the rotor end face and the end face of the oil dispensing disk should be within a range of 0.04 ~ 0.07mm after installation.
The tightening force of the tackle connecting bolts should be even, and when rotating the rotor by hand, the rotation balance and non-clamping resistance phenomenon are qualified.
