A brief description of the difference between CQ magnetic pump and CQB magnetic pump

【Pump network in Asia】 Magnetic pump is through the magnetic transmission to achieve non-contact torque transfer, and then replace the dynamic seal with a static seal to achieve a pump without leakage of a pump. As the pump body and the isolation sleeve completely close the shaft and the inner magnetic rotor, the hidden dangers of inflammable, explosive, poisonous and harmful media leaked through the seal are completely eliminated, thereby further ensuring safety in production and environment. In view of this, the magnetic pump is generally used in the pump has strict requirements of the chemical industry, petroleum and other industries. A brief description of the difference between CQ magnetic pump and CQB magnetic pump Magnetic pump is a centrifugal pump is a pump, magnetic actuator, the motor consists of three parts. Ordinary centrifugal pump motor directly driven pump impeller, or driven by the coupling impeller The magnetic pump is driven by the magnetic impeller. No mechanical seal, effectively prevent water leakage. However, the magnetic pump can only do part of the low-power magnetic drive part of the internal and external magnetic rotor components; spacer and the magnetic medium within the rotor and magnetic isolation; external magnetic rotor driven by the motor, Rotate, complete the non-contact torque transfer, so as to achieve the purpose of driving the pump. Magnetic pump, the structure is simple and compact. Unique lubrication and cooling circuit, a part of the process of liquid self-lubricating and cooling transmission components, eliminating the need for mechanical seal pump cooling, washing, quenching and other complex systems. Design inlet pressure up to 30MPa, mechanical seal pump is difficult to do this. Compared with the use of mechanical seal or packing seal centrifugal pump, the magnetic pump has the following advantages: 1. The pump shaft from the dynamic seal into a closed static seal, to completely avoid media leakage; 2. Without independent lubrication and cooling water, reducing Energy consumption; 3 by the coupling into a synchronous drive drag, there is no contact and friction. Low power consumption, high efficiency, and damping damping effect, reducing the impact of motor vibration pump and pump cavitation vibration impact on the motor; 4 overload, the inner and outer rotor relative slippage, the motor, Pump protection. Performance difference between the two is: the same conditions, the efficiency of the magnetic pump is lower than the efficiency of the centrifugal pump! This is the fundamental difference!
