Description
Technical Field
The utility model relates to a stainless steel magnetic drive pump.
Background
Stainless steel magnetically driven pumps typically consist of an electric motor, a magnetic coupling and a corrosion resistant centrifugal pump. The main characteristic is that the magnetic coupling is used to transmit power, there is no leakage, when the motor drives the outer magnet of the magnetic coupling to rotate, the magnetic line of force passes through the gap and the isolation sleeve, and acts on the inner magnet, so that the pump rotor and the motor rotate synchronously, and the torque is transmitted without mechanical contact. At the power input end of the pump shaft, there is no leakage because the fluid is enclosed in a stationary spacer sleeve, and there is no dynamic seal. The device is suitable for industries such as petroleum, chemical industry, pharmacy, smelting, electroplating, environmental protection, food, film and television printing, water treatment, national defense and the like, and is ideal equipment for conveying flammable, explosive, volatile, toxic and rare valuable liquids and various corrosive liquids.
However, the conventional magnetic force driven pump has the following defects:
1. the conventional magnetic pump can not be used in the occasions with higher temperature, so that the application range of the conventional magnetic pump is not wide.
2. The transmission shaft and the pump body have high noise and serious abrasion during working, and cannot ensure long-period running.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide one kind and be applicable to the high temperature operating mode, the noise is lower, can guarantee the equipment long-term operation to balanced inside holistic axial force, increased the self-loopa volume, played the stainless steel magnetic drive pump of lubricated and cooling effect.
The purpose of the utility model is realized like this:
the stainless steel magnetic drive pump comprises a pump body, wherein an impeller is arranged inside the pump body, the rear end of a main shaft of the impeller is connected with a transmission shaft, a pump cover is arranged at the rear end of the pump body, the rear end of the transmission shaft is connected with an output shaft of a motor, an inner magnetic steel assembly is arranged outside the transmission shaft, the inner magnetic steel assembly is connected with the transmission shaft, an isolation sleeve is arranged outside the inner magnetic steel assembly, an outer magnetic steel assembly is further arranged outside the isolation sleeve, a bearing box is arranged outside the outer magnetic steel assembly, a cooling jacket is welded inside the bearing box, a cooling medium is introduced into the cooling jacket, two alloy sleeves and four alloy rings are arranged between the transmission shaft and the pump body and are oppositely ground.
The pump cover is provided with a balance hole, and the transmission shaft is designed as a through shaft.
The utility model discloses stainless steel magnetic drive pump has following advantage:
1. the cooling jacket is arranged in the bearing box, so that the magnetic pump can be suitable for occasions with higher temperature, and the application range of the magnetic pump is improved.
2. Two alloy sleeves and four alloy rings are arranged between the transmission shaft and the pump body for opposite grinding, so that the noise is reduced, and the long-period operation can be ensured.
3. The pump cover is additionally provided with the balance hole, the transmission shaft is designed to be a through shaft, and the inner magnetic steel is designed in a light weight mode, so that the whole axial force inside is balanced, the self-circulation amount is increased, and the good lubricating and cooling effects are achieved.
