Condition check


    Uncover the pump. Press a planeness measuring instrument (an edge of a steel ruler) to an internal surface of a cover of the pump and try to palm off under it an edge probeа in the thickness of 0,038 mm. If probe passes in a backlash, the pump should be replaced. Take a conducted gear wheel of the pump and measure by a micrometer its thickness. If the thickness of a conducted gear wheel appears less than admissible value under Specifications, it is necessary to replace the pump. The leading gear wheel has the same minimum admissible thickness.
    By means of a micrometer measure a thickness of a conducted gear wheel of the pump and compare result to the data of Specifications.
    By means of measuring probeа define backlash size between a conducted gear wheel of the pump and a wall of its case, between acting ends of a teeth of leading and conducted gear wheels, and also between gear wheels and a pump cover. Compare results of measurements to the data of Specifications, in case of excess of admissible limits replace the pump.
    Measure a backlash between a conducted gear wheel and the pump case.
    Measure a backlash between acting parts of a teeth of gear wheels of the pump.
    Measure a backlash between gear wheels of the pump and its cover.
