Description

A kind of all risk insurance temperature magnetic drive pump

Technical field

The present invention relates to a kind of magnetic drive pump, be specifically related to a kind of all risk insurance temperature magnetic drive pump.

Background technique

Magnetic drive pump is conventional fluid conveying machine, with it without leakage, low noise, the advantage such as stable, is widely used in the industries such as medicine, chemical industry, bathroom.Magnetic drive pump comprises housing, impeller, pump cover, pump shaft, interior magnet rotor, separation sleeve, outer magnet rotor, motor and is positioned at the liner plate of motor end, outer magnet rotor and motor shaft affixed, interior magnet rotor and pump shaft affixed, separation sleeve is made up of flange, thin-walled cylinder and base plate, separation sleeve flange connects with pump cover, the outer magnet rotor of driven by motor rotates, then in driving, magnet rotor rotates, and interior magnet rotor is driven member.The conveying easily-crystallized medium of magnetic drive pump; housing, pump cover, interior magnet rotor place easy crystal medium easily solidify and become powdery, bulk; resistance is large; bearing damage can be caused; even cannot start, the easy crystal medium at housing and pump cover place easily melts, but the easy crystal medium at interior magnet rotor place cannot melt because thermal source cannot reach this region; cause being difficult to shut down at any time and start, add customer using cost.

Summary of the invention

The object of the present invention is to provide a kind of all risk insurance temperature magnetic drive pump preventing medium from condensing.

The technological scheme that the present invention takes is:

A kind of all risk insurance temperature magnetic drive pump, comprise pump case, rotary shaft rack is provided with in pump case, described rotating shaft is connected to rotary shaft rack, the inner chamber of pump case is divided into active chamber and power cavity by described rotary shaft rack, internal rotor is provided with in described power cavity, internal rotor is fixedly installed in one end of rotating shaft, impeller is provided with in active chamber, the rotating shaft the other end that impeller is installed on, the cavity of the top of described impeller is provided with material feeding mouth, cavity on the left of impeller is provided with discharge port, the insulation jacket covering active chamber is provided with outside described pump case, described insulation jacket is provided with the adpting flange of UNICOM's insulation jacket, the right side of described power cavity is provided with pump cover, described pump cover is installed on pump case through screw, the external rotor coordinated with internal rotor is provided with in described power cavity, described external rotor connects the power source outside pump case, separation sleeve is provided with between described internal rotor and external rotor, the mounting end of described separation sleeve is fixed between pump case and pump cover, and separation sleeve and pump cover surround a closed chamber, and described external rotor is arranged in closed chamber, surround sealed thermal insulating chamber between described rotary shaft rack and pump housing endophragm, described incubation cavity covers power cavity and rotating shaft, and described pump case is provided with the adpting flange of UNICOM's incubation cavity.

After taking above technological scheme, beneficial effect of the present invention is: traditional magnetic drive pump is only incubated to the impeller of active chamber and charging and discharging mouth the insulation that have ignored power cavity.In the technical program, except of the prior art to except the insulation at active chamber and inlet/outlet place, also utilize between the inwall of rotary shaft rack and pump case and form incubation cavity, incubation cavity covers whole power cavity and rotating shaft, has an impact after avoiding the medium entering power cavity to condense to magnetic drive pump; Utilize separation sleeve to be kept apart by the inner and outer rotors of magnetic drive pump, avoid external rotor contaminated.
