Abstract

Magnetic drive pump comprises the magnetic shaft coupling that comprises outer magnet rotor and interior magnet rotor.Outer magnet rotor is driven by individual motor.Outer magnet rotor radially is placed in the outside of separation sleeve.Interior magnet rotor radially is placed in the inside of separation sleeve, and the rotation of magnet rotor causes the magnetic drive pump rotor rotation successively in making.Magnetic drive pump rotor driven centrifugal pump impeller is with moving liquid.The outside that gas bubble detection is placed in separation sleeve makes it be positioned at the dried side of magnetic drive pump.Gas bubble detection sends signal and enters the wet side of magnetic drive pump whether to have gas in the identification magnetic drive pump fluid.

Description

The non-intrusion type steam detector that is used for magnetic drive pump
[technical field]
The application relates to a kind of method of using steam detector to survey the gas in the interior liquid stream of magnetic drive pump.
[background technique]
Magnetic drive pump is known, and typically comprises the magnetic shaft coupling (magnetic coupling) that drives centrifugal pump impeller.Motor is connected in the outer magnet rotor of magnetic shaft coupling.The interior magnet rotor of magnetic shaft coupling links to each other with pump impeller.Separation sleeve is placed between outer magnet rotor and the interior magnet rotor, and fluid-tight completely is provided, and guarantees that outer magnet rotor maintains " doing " side.Liquid circulates in separation sleeve " wetting " side inside.Centrifugal pump impeller moves to outlet with liquid from inlet.
Prior art has comprised the gas bubble detection of the wet side that is placed in magnetic drive pump to survey bubble or other gas of liquid internal.
[summary of the invention]
Magnetic drive pump comprises the magnetic shaft coupling that drives centrifugal pump.The outer magnet rotor of motor driving magnetic shaft coupling.Outer magnet rotor radially is placed in the outside of separation sleeve.Interior magnet rotor radially is placed in the inside of separation sleeve.The rotation of magnet rotor in the rotation of outer magnet rotor causes.Interior magnet rotor drives centrifugal pump impeller with moving liquid.Gas bubble detection is placed in the separation sleeve outside, makes it be arranged in the dried side of magnetic drive pump.This gas bubble detection sends signal and enters the wet side of magnetic drive pump whether to have gas in the identification magnetic drive pump liquid.
According to following specification and accompanying drawing, these and other characteristics of the present invention can be understood best, below are brief description of drawings.
[description of drawings]
Fig. 1 is the sectional view of magnetic drive pump of the present invention.
Fig. 2 is the assembling detail drawing of gas bubble detection probe.
[embodiment]
Magnetic drive pump shown in Figure 1 has separation sleeve 22, and separation sleeve 22 will be done side 23 and isolate with the wet side 40 that is used for fluid pump.Individual motor is by cartridge housing 24 live axles 28.Axle 28 drives outer magnet rotor 30, and this outer magnet rotor 30 is placed in the outside of separation sleeve 22.Magnetic flux passes separation sleeve 22 and drives interior magnet rotor 32.Centrifugal pump impeller 34 is connected in interior magnet rotor 32.Fluid 35 flows to impeller 34 from entering the mouth, and flows to outlet 37 through driving.
Gas bubble detection probe 36 is placed in separation sleeve 22 outsides, and communicates by letter with controller 38.This probe can be the ultrasonic probe that can launch and accept ultrasonic signal.Be different from transmitting through transmitting of liquid through gas.Therefore, probe 36 can determine that the fluid in the wet chamber is the mixture of liquid, gas or liquids and gases.
Magnetic drive pump comprises " wetting " side 40, should " wetting " side 40 receive some liquid that pumped into by impeller 34, makes liquid radially to circulate around element in separation sleeve 22.In addition, " doing " side 23 radially is placed in the separation sleeve outside and does not receive liquid.Probe 36 is placed in to be done in the side 23.
Comprehensive is that probe 36 is faced the part with impeller 34 isolated wet sides 40.This setting makes probe 36 align with the part of the chamber of opening by shell wall 100 and impeller isolation.
According to Fig. 2 and with reference to what figure 1 can fully understand is that probe 36 is placed in the opposite of bushing holder 100.Casing wall 101 receives olive/nuclear device 110 to clamp and to keep probe to enter shell.
Separation sleeve 22 is formed by nonmagnetic substance.Be used to form suitable, to send the technology of ultrasonic transmitter that penetrates separation sleeve 22 and arrive at apparent surface's signal be known.Basically, by the signal that analysis is returned, controller 38 can confirm whether to exist in the magnetic drive pump fluid bubble of steam or gas.Although it is known that the technology of such probe is provided, utilize this probe in the mode of this non-intrusion type.
Although embodiments of the present invention are open, person of skill in the art will appreciate that within the scope of the invention some change will take place.Therefore, should study following claim to determine real scope of the present invention and content.
