What Are The Factors That Cause Damage To The Seal Of High Viscosity Rotary Lobe Pump?

There are many factors that can cause damage to the seal of a high viscosity lobe pump, today Ace lobe pump's mainly introduce two important factors to you.

(1) Pump installation problems

High viscosity lobe pump vibration on the mechanical seal is particularly serious, so the pump coupling installation on the heart is an important factor. In addition, the amount of shaft string, seal box end face and shaft perpendicularity, gland and seal box stop gap, pump cover and pump body stop gap, sleeve and radial runout, etc., the size of these parts of the standard, the seal will have an impact.

(2) Mechanical seal assembly accuracy problems

High viscosity lobe pump mechanical seal assembly accuracy is not scientific is also a factor that causes seal damage, such as moving static ring installation concentricity is not enough, mechanical seal installation compression amount is not suitable, etc.. Compression amount is too large will lead to dynamic, static ring end face fit too closely, when running can not be opened normally to form a liquid film, serious wear and failure, compression amount is too small end face pressure is too small, easy to run in the process of pressure fluctuations, pump vibration and other factors, the seal surface open failure.

The above two points are the important factors affecting the damage to the seal of high viscosity lobe pump. To learn more about high viscosity lobe pumps please follow our website: http://www.gtgoodpump.com/
