Description
Technical field
The utility model relates to magnetic drive pump, technical characteristics is the live axle sealing of magnetic drive pump.
background technique:
Magnetic drive pump comprises the pump housing 1, pump cover 2, pump shaft 3, impeller 4, interior magnet rotor 5, separation sleeve 6, outer magnet rotor 7, link press span 8, live axle 9, bearing housing 10, separation sleeve 6 and pump cover 2 are sealedly and fixedly connected and make shaft seal, are arranged on interior magnet rotor 5 on pump shaft 3 in separation sleeve 6 to rotate with the outer magnet rotor 7 mating band pump shaft 3 of separation sleeve 6 outside.
Prior art is between the bearing gland and live axle 9 of bearing housing 10, or the bearing gland of bearing housing 10 is just provided with dust pan and labyrinth seal structure with the shaft room of the outer magnet rotor be arranged on live axle 9, it just plays dust-proof and stops the lubricant leakage do not had in the bearing housing 10 of pressure.
In operation process, the ferromagnetism be mixed with in medium or particulate contamination can enter in separation sleeve and cause wear and leakage to separation sleeve, or separation sleeve 6 is leaked because of other reason, separation sleeve 6 is once the high-pressure medium leaked in its inner chamber enters into link press span 8 inner chamber, can along live axle 9 gap to external leakage, and dust pan on live axle 9 and labyrinth sealing do not stop high-pressure medium along live axle 9 to external leakage, cause magnetic drive pump to leak, producers cannot effectively control fast.Because magnetic drive pump fed sheet of a media major part is inflammable, explosive, poisonous, harmful or somewhat expensive dense media, separation sleeve, once leakage not only can affect production, pollutes, even jeopardizes the life safety of producers.
Model utility content
The purpose of this utility model improves for the shortcoming deficiency of above-mentioned prior art, a kind of live axle automatic-sealed magnetic drive pump is provided, to improve the property safe and reliable to operation of magnetic drive pump, reach and carry out automatic secondary sealing and warning when separation sleeve leaks, provide the reply time for producers make remedial measure.
The utility model magnetic drive pump comprises the pump housing 1, pump cover 2, pump shaft 3, impeller 4, interior magnet rotor 5, separation sleeve 6, outer magnet rotor 7, link press span 8, live axle 9, bearing housing 10, separation sleeve 6 and pump cover 2 are sealedly and fixedly connected and make shaft seal, are arranged on interior magnet rotor 5 on pump shaft 3 in separation sleeve 6 to rotate with the outer magnet rotor 7 mating band pump shaft 3 be fixedly mounted on separation sleeve 6 outer drive shaft 9 axle head; It is characterized in that being provided with dry gas formula mechanical seal device 12 between the shaft sleeve part of magnet rotor 7 outside and the end cap of bearing housing 10; And warning inductive sensor 13 is provided with in link press span 8 inner chamber.
Dry gas formula mechanical seal device is a kind of mechanical seal device used for gas medium, at it, quiet or kinetic friction ring end face offers power and carve groove, when kinetic friction ring and static friction ring relatively rotate, power is carved groove and gas is introduced sound frictional fit end face, produce end thrust compensated loop (moving) friction ring and static friction ring are pushed open, make kinetic friction ring and static friction ring form gap to be rotatably assorted, the production of frictional heat is very little, can keep safe handling for a long time.
Although the design of dry gas formula mechanical seal device is in order to for gas seal, but use in liquid medium environment, good sealing effect can be reached equally, just weaker relative to the sealing effect being exclusively used in the mechanical seal device used in liquid medium body environment.
The utility model is owing to being provided with dry gas formula mechanical seal device 12 between the shaft sleeve part of magnet rotor 7 and the end cap of bearing housing 10 outside, and when not having dielectric leakage, dry gas formula mechanical seal device 12 is in idling conditions in gaseous environment.
When separation sleeve 6 leaks, when high-pressure medium enters into link press span 8 inner chamber, utilize the sealability pair of dry gas formula mechanical seal device 12, the medium leaked in link press span 8 inner chamber carries out mechanical seal, prevents medium from leaking into outside pump further by bearing housing 10.The inductive sensor 13 be simultaneously arranged in link press span 8 inner chamber is changed by the pressure of induction link press span 8 inner chamber or induced liquid medium occurs carrying out leakage alarm.For producers provide the sufficient time, carry out safe and effective disposal.
The utility model structure is simple, easily manufactured, live axle is fully effectively sealed, substantially increases the property safe and reliable to operation of magnetic drive pump, reach and carry out automatic secondary sealing and warning when separation sleeve leaks, provide the reply time for producers make remedial measure.
