| Use points 1, test: check the connection is loose; the rotor rotation circle dynamic coupling disc by hand, crew rotation is flexible, whether there is noise and weight unevenness feeling, to determine whether the foreign body or the pump shaft is bent, the seal installation is not correct; check the seal cavity clean 20 lubricating oil is filled with 1/2 cavity space; pump unit surface is clean; the steering unit no-load test. 2, manual start: filling pump (for the first time), slightly open the outlet valve, start the motor, the pressure rise and confirm the pump group is running smoothly when the valve is open to the operating requirements. 3, operation check: pipeline pump in normal operation, should regularly check and record the pump current meter, voltage meter, import and export of vacuum gauge, pressure gauge and flow meter readings, unit vibration, noise and temperature rise is normal, there is no air seal oil leakage. 4, normal shutdown: close the discharge valve, so that the pump light load, stop motor. Emergency shutdown: The pump motor current meter indicates the exception (too large or very little); the pump system sends out unusual noise. The vacuum pump inlet pressure gauge, pressure gauge instructions export abnormal vibration pump body and a different sound of a larger, serious decline in performance. The odor pump motor, the shaft seal oil leakage of air, bearing temperature more than 75 degrees. Installation method 1, radial shaft beating equipment should be less than or equal to 0.04 mm, the axial movement does not allow more than 0.1 mm; 2, the sealing parts of the equipment should be kept clean at the time of installation, sealing parts should be cleaned, the sealing surface intact, to prevent impurities and dust into the sealing parts; In 3, the installation process is strictly prohibited, hit the beat, so as not to damage the mechanical seal friction seal failure; 4, the installation of the sealing surface should be coated with a layer of clean mechanical oil, so that it can be installed smoothly; 5, the installation of static ring gland, tighten the screws must be uniform stress, the vertical static ring end face and the requirements of the axial line of the; 6, after the installation of the hand to drive the ring, can make the moving ring in the shaft flexible movement, and has a certain flexibility; 7, after the installation of the rotating shaft with the hand wheel, the shaft should be no sense of weight; 8, the equipment must be full of media before operation, in order to prevent dry friction and seal failure; |
