CQ Magnetic Driven Circulation Chemical Centrifugal Pump

1.CQ type magnetic drive pump Product Overview:

CQ type magnetic drive pump ( magnetic pump for short ), CQG -temperature magnetic drive pump ( temperature ≤ 250 C) ( referred to as magnetic pump ) is a new product will be applied to the working principle of permanent magnetic coupling centrifugal pump , the main material stainless steel, reinforced polypropylene, plastic . Reasonable design, advanced technology, with fully sealed , no leakage, corrosion-resistant features , its performance has reached the advanced level of similar foreign products.
Magnetic pump with static seal instead of dynamic seal , the pump flow components are completely sealed , solve the other pump mechanical seal can not be avoided run, run, drip of ills. Magnetic pump corrosion-resistant , high-strength plastic , corundum ceramics , stainless steel and other materials for manufacturing , so it has good corrosion resistance, and can be transported medium from pollution.

2.CQ type magnetic drive pump range :

Magnetic pump compact structure, beautiful appearance , small size, low noise , reliable operation , easy to use vertical . It can be widely used in chemical , pharmaceutical, petroleum , electroplating , food , film photofinishing , research institutions, defense industry and other units pumping acid , lye , oils, rare and precious liquid , venom , volatile liquid , and circulating water equipment , filter support. Particularly susceptible to leakage , flammable, explosive liquid substance pumping, the use of this pump is more ideal .

3.CQ type magnetic drive pump installation and use

1 , magnetic pump should be installed horizontally , not upright , plastic tubing pump can not bear the weight , the special requirements for vertical installation of the occasion, the motor must be upward .
2 , when the suction surface above the center line of the shaft , before starting the suction pipe valve to open , if the aspiration level is below the center line of the shaft , the end of the pipe to be equipped with a valve .
3 , should be checked before using the pump , motor fan rotation to be flexible, no stuck no abnormal sound , each fastener to be tightened.
4 , check the motor rotation direction is consistent with the magnetic pump turning mark .
5 , after the motor is started , slowly open the discharge valve until after the pump into the normal working state , and then open the discharge valve to the desired degree .
6 , the pump stops before work , should be closed discharge valve , then close the suction pipe valve.

4.CQ type magnetic drive pump Precautions

1 , due to the cooling and lubrication magnetic pump bearing is being conveyed by the media , so the absolute prohibition of air moving forward, while avoiding the middle of a power outage at work caused by space and time are set and then start running .
2, the transmission medium , if they contain solid particles, the pump inlet filter to add : if it contains ferromagnetic particles , magnetic filter to be added .
3 , the pump is in use ambient temperature should be less than 40 C, the motor temperature should not exceed 75C.
4 , and the temperature of the medium is transported in a pump timber should be within the allowable range ( see table ) . Plastic pump temperature <60 C, metal pump temperature <100 C, conveying suction pressure of not more than 0.2mpa, maximum working pressure 1.6mpa, density is not greater than 1600kg/m3, the particle size of not more than 30 × 10 - 6m2 / s the non-liquid hard particles and fibers .
5, for conveying fluid is easily precipitated crystalline media , should be cleaned after use , drain pump fluid in the net . 6 , magnetic pump after 500 hours of operation , should wear dismantling the bearing ring and face , the gap is greater than if the bearings and bushings 0.5 ~ 1mm, impeller axial movement of 1.5 to 2mm, the move should replace the bearings and axial ring .
