Abstract
The present invention relates to an axial force balancer of a high-lift submerged mine pump, which is composed of a mechanical seal head face friction pair; wherein, the mechanical seal head face friction pair, which is mounted behind the final-stage vane wheel of the pump and composed of a moving ring (2) and a static ring (1), separates the fluid of the outlet of the final-stage vane wheel from the air or a low-pressure area; the output pressure of the final-stage vane wheel (3) is in front of the head face friction pair; a backflow hole (5) which is communicated with a well cavity or one low-pressure stage is arranged behind the head face friction pair; the outer diameter of the head face friction pair of the pump is 0.8 to 1.0 time larger than the diameter of the sealing ring of the vane wheel of the pump. The axial force balancer has the following advantages: almost no leakage occurs; the energy-saving effect of the pump is improved; the structure is simple and reliable; the sand-proof effect is good; the operation reliability and service life of an assembly are increased.
Description
Technical field
The present invention relates to a kind of high lift mining diving pump axial force balancing device.
Summary of the invention
Traditional balance unit for pump axial force exists leakage rate big. complex structure, and dustproof effect is poor, complex structure, working life is short.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of high lift mining diving pump axial force balancing device is provided, increase the service life.
Technological scheme of the present invention is: a kind of high lift mining diving pump axial force balancing device is characterized in that: by being contained in pump not after the level impeller, the play staff that rubs of the mechanical seal end surface of fluid and the atmosphere or the low pressure area full gate of level impeller outlet is not become; The end-face friction minor flank has the return port that communicates with well chamber or a certain low pressure stage; The 0.8-1.0 that the secondary external diameter of the end-face friction of pump is a pump impeller choma diameter doubly.
Beneficial effect of the present invention: almost do not have leakage, the energy-saving effect of pump improves, and simple and reliable for structure, sand controlling result is good, improves unit operation reliability and life-span.
