Wilden pump flow regulator

Wilden pump flow regulator is adjusted by turning the adjusting mechanism to change the piston stroke.The principle is: the rotation regulating mechanism of the hand wheel (can see the change of position on the dial), via an adjustable shaft and the shaft sliding axially transform this movement into the radial direction of the eccentric shaft by sliding chutedisplacement, through the connecting rod to push the piston, due to the change of the piston stroke, so as to achieve the purpose of the flow regulator.
Diaphragm overhaul and different other forms of pump,
1,Diaphragm pump and valve check should be noted that the sealing ring is aging deformation spring stretch is seriously reduced, the valve port spool for wear, corrosion and other defects, the valve face should be installed with the pump flange surface level, not recessed;
Adjusting mechanism disassembly calibration location of the stroke length (stroke length 5mm) Remove the scale table seat ring slides into the scale calibration position, measure the length of the stroke should be fully consistent with the scale table;
3 piston disassembly, use special pointed tool packing ring is removed from its slot, and be careful not to damage the ring groove;
4, worm gear to inspect the teeth should be intact, there should be no cracks or broken teeth meshing To check the installation.
