The fracture of bellows is caused by fatigue failure due to excessive elongation or distortion in tension. Reasons for excessive elongation or distortion of thermoplastic extrusion melt pumps include: (1) Vigorous vibration is caused by mis
During the long-term use of the melt gear pump , leakage will occur, which seriously affects its production operation. For the leakage of the melt gear pump, it mainly exists in the leakage of the axial clearance. How to effectively reduce
When the melt metering pump is in use, because of the operation relationship of various parts of the machine, it is easy to appear the phenomenon of vibration. Vibration phenomenon will have a certain impact on the use of the melt metering
The flow rate of the thermoplast extrusion pump head varies with the change of the outlet pressure, but the fluctuation of the general outlet pressure can not exceed (+10 psi). If the fluctuation is large, it is likely to be a transmission
The conveying device of the melt metering pump is composed of three parts: the transmission system, the melt metering pump and the control system. The drive system includes AC motor, reducer and frequency converter, while the control system
