1.lobe pump manufacturers from the design, production and manufacturing stage to remove vibration (1) The design of the shaft, in the design, the resonant frequency of the rotating shaft should be used to bypass the angular frequency of the motor. Improve the production quality of the shaft, avoid quality shaft force and excessive dimensional tolerance. (2) The selection of rolling bearings, the selection of rolling bearings without wetting. 2. Remove vibration from the installation and protection process (1) Before installation, check whether the pump shaft, motor bearing and rotating shaft have bending deformation and quality shaft force. (2) the anchor bolt spacing isn't good, ductility column pin and elastic ring fusion can not be too tight, coupling is the interaction of internal thread on the shaft is too loose, if it is too loose, the choose such as spray paint to reduce coupling nominal diameter until the do clearance fit the demand of specifications, and then the coupling fixed on the shaft.
(3) the void value is not in line with the provisions, the local wetting is not good, improve the maintenance technical level of the pump shaft extraction tile, strictly follow the first scraping tile, grinding, in the scraping tile cycle process, to ensure that the piston pin and shaft force contact the total area to achieve the requirements of the specification. (4) Timely treatment of the condition of the support point parts with vibration, to avoid the reduction of resonance frequency due to the difficulty and the reduction of bending stiffness. (5) Ensure that the motor bearing void is suitable, regular maintenance, easy to damage parts. 3. Remove the vibration caused by the choice of pump model and the actual poor operation. Two pumps and should ensure that the pump performance is the same, in the selection of lobe pump, performance curve should be slow down type is good, can not have camel peak. In order to avoid the vibration amplitude of the pump is too large, the vibration can be accurately measured and analyzed to ensure the correct operation of the pump.
