1. manufacture parts method for detecting cleaning degree again, it is characterized in that, as follows:

  • Step 1 cleaning pressure tank, cleaning vessel, change film filter, whether have leakage gas leak phenomenon, after cleaning up, carry out drying if detecting each device during cleaning;

    The filter paper that step 2 exchanges film filter uses drying baker to dry in advance;

    Step 3 is weighed to the filter paper after original drying, and by weighing data record in the table;

    Step 4 is outwarded winding and is changed film filter, puts into the filtering membrane of oven dry, and screws;

    Step 5 adds cleanliness detection clean-out system by funnel in head tank;

    Step 6 connects vacuum pressure pump and head tank, connects a spray gun in the outlet of head tank;

    And at vacuum pressure pump and head tank link position, head tank and spray gun link position, an operation valve is respectively installed;

    Step 7 opens operation valve between vacuum pressure pump and head tank and vacuum pressure pumping source, pressurization, until when head tank pressure reaches setting value, closed control valve, closes vacuum pressure pump simultaneously;

    Step 8 opens the operation valve connecting spray gun, opens spray gun debugging outlet cleaning fluid;

    To be cleaned is cleaned with spray gun in cleaning vessel;

    After step 9 has been cleaned, being poured into by cleaning fluid in cleaning vessel changes in film filter, take out the filter paper changed in film filter, drying is carried out in drying box, after drying, weighing device weighs up quality with the filter paper of impurity again and record, and then observe with finder, the size of checked for impurities and quantity.
