Product Introduction

Practice has proven that appropriate end face flushing is an improvementpipeline pumpOne of the important auxiliary measures for the durability of mechanical seals is the more significant effect on the shaft seal of hot oil pumps in refineries. In addition, for liquid hydrocarbon shaft seals with poor lubricity and easy volatility, flushing measures must be taken in order to quickly remove heat and prevent liquid film vaporization. Generally speaking, when PsV>7.0 (MPa. S). (m/s), flushing measures should be taken. For those end face temperatures that are not high and the temperature of auxiliary components does not exceed the heat resistance limit, flushing measures are generally not necessary. In recent years, from the introduction of some production equipment from abroad, the mechanical seal flushing device has become an integral part of the mechanical seal, and some have even systematized the flushing pipeline.

Product Features

The mechanical seal end face flushing of the mechanical seal flushing pipeline pump has two functions:
1. It can take away the frictional heat, stirring heat, etc. of the mechanical seal in the sealing chamber of the machine seal flushing pipeline pump to reduce the temperature of the sealing end face and ensure the stability of the fluid film on the sealing end face;
2. It can prevent solid impurities and oil coke from accumulating in the sealing chamber, enabling the mechanical seal to work in a good and stable working environment, and reducing the possibility of wear and seal component failure.
in the market nowManufacturer of machine sealed flushing pipeline pumpMany, which is a good machine seal flushing pipeline pump? Dadonghai Pump Industry specializes in producing machine sealed flushing pipeline pumpssewage pumpThe models are very complete, welcome everyone to come for consultation and purchase.

Product Usage

Machine sealed flushing pipeline pumps are mainly used for conveying viscous and easily crystallized media or media with small particles, but it is necessary to consider whether the media and materials used for flushing are compatible (the selection of pipeline pumps should be done well).
