CQ type magnetic drive pump ( referred to as magnetic pump) is a new product that applies the working principle of permanent magnet coupling to centrifugal pumps. It has reasonable design, advanced technology, full seal, no leakage, corrosion resistance, etc., and its performance reaches abroad. Advanced level of similar products.

I. Main features:

The magnetic pump replaces the dynamic seal with a static seal, so that the overcurrent parts of the pump are completely sealed, which completely solves the problems of running, running, and dripping that other pump mechanical seals cannot avoid. The magnetic pump uses corrosion-resistant, high-strength engineering plastics, steel-jade ceramics, and stainless steel as manufacturing materials, so it has good corrosion resistance and can protect the conveyed medium from pollution.

Product use:

The magnetic pump has a compact structure, beautiful appearance, small volume, low noise, reliable operation and convenient use and maintenance. Can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photofinishing, scientific research institutions, defense industry and other units to pump acid, lye, oil, rare precious liquid, venom, volatile liquid, and supporting equipment for circulating water, Matching filter. Especially for pumping leaking, flammable and explosive liquids, this pump is more ideal.

Third, installation and use:

1. The magnetic pump should be installed horizontally and should not be erected. The plastic pump body must not bear the weight of the pipeline. For vertical installation with special requirements, the motor must face upward.
2. When the pumping liquid level is higher than the pump shaft centerline, open the suction pipe valve before starting. If the pumping liquid level is lower than the pump shaft take-up line, the pipe must be equipped with a bottom valve.
3. The pump should be checked before use. The motor blades must be flexible to rotate, no jamming and noisy sounds, and all fasteners must be fastened.
4. Check whether the motor rotation direction is consistent with the magnetic pump steering mark.
5. After the motor starts, slowly open the discharge valve. After the pump enters the normal working state, adjust the discharge valve to the required opening.
6. Before the pump stops working, close the discharge valve first, and then close the valve of the suction pipe.
 

4. Faults and troubleshooting:

1.Because the cooling and lubrication of the magnetic pump bearings rely on the medium being transported, dry running is absolutely forbidden. At the same time, no-load running is caused when the power is turned off and restarted during the work.
2. If the conveyed medium contains solid particles, a filter must be added to the pump inlet: if it contains ferromagnetic particles, a magnetic filter must be added.
3. The ambient temperature of the pump in use should be less than 40 ° C, and the temperature rise of the motor must not exceed 75 ° C.
4. The conveyed medium and its temperature should be within the allowable range of the pump material. The operating temperature of engineering plastic pumps is <60 ° C, the operating temperature of metal pumps is <100 ° C, the auxiliary suction pressure is not greater than 0.2MPa, the maximum working pressure is 1.6MPa, the density is not greater than 1600 ^ kg / m3, and the particle size is not greater than 30 X 10 -6㎡ / S liquid without hard particles and fibers.
5. For the medium that is easy to precipitate and crystallize, the transport liquid should be cleaned immediately after use to drain the liquid accumulated in the pump.
6. After 500 hours of operation of the magnetic pump, the wear and inertia of the bearing and the end-moving ring should be disassembled. If the gap between the bearing and the sleeve is greater than 0.5 ~ 1mm, the impeller moves axially 1. 5 ~ 2mm, the bearing and Axial moving ring.
