2. Select the appropriate soft lead wire (diameter 0. 5 < d < 1. 3mm) 2 segments; each length is about the circumference of the gear joint,
3, the operation of the lead wire 1) Install the main and driven gears,
2) Apply three sections of soft lead wire to the pitch circle of the main and driven gears with grease.
3) Install the pump cover (including the gasket and bushing); tighten the nut symmetrically and evenly in 2 to 3 passes.
4) Unscrew the pump cover nut symmetrically and evenly; remove the pump cover; remove the soft lead wire and keep it clean.
5) Select 4 measuring points on each lead wire; measure the thickness of the soft lead wire with the outer diameter micrometer and record it.
4. Analysis of measurement data 1) Calculate the average value of 8 measurement values; that is, axial clearance,
2) According to the measured axial gap value and the normal value scale (usually 0. 06 ~ 0. 10mm; low-pressure gear pump promised to 0. 10 ~ 0. 25mm); make a sustainable application may need to repair the conclusion.
