Ningbo Emulsion Pump Manufacturer states that rotor pumps are characterized by long service life, high mechanical efficiency, and convenient disassembly and maintenance. Therefore, there are almost no parts damaged in rotor pumps (except for mechanical seals). The motor rotors of the movable plunger pumps are not prone to friction between rotors, and there are no wearing parts. However, during the daily cleaning of cam-driven double rotor pumps, vibration may occur during the entire operation. So, how to eliminate this vibration?
I. Ningbo Emulsion Pump Manufacturer suggests eliminating vibration from the design and manufacturing stage:
1.The design of the shaft should bypass the resonant frequency between the motor's angular frequency and the shaft, improving the manufacturing quality of the three-plunger high-pressure pump's supply shaft to avoid excessive axial force and dimensional tolerances.
2.Select rolling bearings that do not require lubrication.
3.Utilize stress relief system software. When designing pumps for transporting boiling water, release the structural stress caused by pump casing deformation in the connected intermediates.
II. Ningbo Emulsion Pump Manufacturer suggests eliminating vibration throughout the installation and maintenance process:
1.Before installation, check the pump shaft, motor bearings, and rotating shaft for bending deformation and axial force.
2.Ensure that the spacing of the anchor bolts is appropriate. The fusion between the malleable locating pins and the elastic throw rings should not be too tight. Check if the internal threading of the coupling is too loose on the shaft. If so, reduce the nominal diameter of the coupling, for example, by painting, until it meets the specifications required for clearance fit, and then fix the coupling to the shaft.
3.Check if the clearance values comply with the regulations and if all lubrication points are functioning well. Improve the technical level of pump shaft bearing repair, strictly following the cyclic procedure of first scraping the bearing and then grinding and scraping it, to ensure that the total contact area between the piston pin and the shaft strength meets the required specifications.
4.Promptly address fatigue in supporting components that exhibit vibration to avoid a reduction in resonance frequency due to decreased difficulty and bending stiffness from the high-pressure reciprocating piston pump manufacturer.
5.Ensure that the motor bearing clearance is appropriate and perform regular maintenance, as some parts are prone to damage.
III. Vibration caused by improper pump selection and actual operation
When connecting two pumps in parallel, ensure that their performance is the same. When selecting cam-driven double rotor pumps, the performance curve should be gently descending, with no camel humps allowed. To avoid excessive pump vibration, accurate measurement and analysis of the vibration can also be conducted to determine the pump's main operating parameters.
Alright, that's all for now from Ningbo Emulsion Pump Manufacturer. Thank you for watching, and see you next time.
