The driver comprises a motor (1), a connection frame (2) and a pump body (8), wherein the motor (1) and the pump body (8) are fixedly arranged at the two ends of the connection frame (2); a driving shaft (10) is connected on the motor (1); a driven shaft (9) is connected on the pump body (8); the driven shaft (9) and the driving shaft (10) are positioned inside the connection frame (2); an inner magnetic rotor (7) is arranged on the driven shaft (9); an inner magnetic body (6) is arranged at the periphery of the inner magnetic rotor (7); an outer magnetic rotor (3) is arranged on the driving shaft (10); an outer magnetic body (4) is arranged on the inner ring of the outer magnetic rotor (3); and a spacing sleeve (5) is arranged between the outer magnetic rotor (3) and the inner magnetic rotor (7), is connected with the pump body (8) and is made of a superconducting material, ceramic or plastic. By the high-temperature resistant magnetic force driver, losses in the transmission process can be effectively reduced, and the service life of the equipment can be prolonged.
Description
Technical field
The present invention relates to a kind of high temperature resistant magnetic driver, can be widely used in Roots pump, directly driven type mechanical pump etc. has in the machinery of pressure difference.
Background technique
In the machinery of pressure difference is arranged, for example Roots pump etc. is owing to run up and mechanical wear, make the mechanical seal or the packing seal parts of the power transmission shaft of pump be easier to damage, in case damage to leak and to have a strong impact on degree of vacuum, thereby cause harmful matter leakage in the pump and befouling environment, therefore, people have developed the magnetic driving equipment that can solve mechanical seal or packing seal transmission shaft sealing problem.Magnetic driving equipment realizes that in the mode of flexibility motor and the contactless of the pump housing are connected, and can effectively reduce the loss in the transmission, has prolonged the working life of equipment.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of high temperature resistant magnetic driver is provided, can effectively reduce the loss in the transmission, prolonged the working life of equipment.
The object of the present invention is achieved like this: a kind of high temperature resistant magnetic driver, be characterized in: it comprises motor, the link press span and the pump housing, the motor and the pump housing are fixedly set in the two ends of link press span, be connected with driving shaft on the motor, be connected with driven shaft on the pump housing, described driven shaft and driving shaft are positioned at link press span inside, interior magnet rotor is installed on the driven shaft, interior magnet rotor outer rim is provided with inner magnet, outer magnet rotor is installed on the driving shaft, and outer magnet rotor inner ring is provided with outer magnet, is provided with separation sleeve between described outer magnet rotor and the interior magnet rotor, separation sleeve is connected with the pump housing, and separation sleeve adopts superconducting material, pottery or plastics are made.
Compared with prior art, the invention has the beneficial effects as follows:
Mainly rely on a kind of high temperature resistant magnetic driver of the present invention inner magnet and the magnetic drives of outer magnet realize that motor is connected with the contactless of the pump housing, reduced the loss in the transmission effectively, and its separation sleeve is made by superconducting material, pottery or plastics, separation sleeve can not produce vortex phenomenon and release heat when driver runs up, and the temperature rising can cause magnet to produce the demagnetization phenomenon, so this uses is novel has the working life of growing.
