1 Product Overview
CQ corrosion-resistant stainless steel magnetic pump is usually composed of an electric motor, a magnetic coupling, and a stainless steel pump head. Its main feature is the use of magnetic couplings to transmit power, completely leak free use of multiple circulation cooling structure, ensuring the reliability and stability of the original power and magnetic transmission. At the same time, the use of column pin couplings reduces the noise and vibration of the water pump. The detachable and column pin couplings are used simultaneously, which increases the structure of the pump and is more conducive to its heat dissipation. At the same time, it is also very convenient for users to repair or replace parts. A cooling fan blade is also designed on the outer rotor of the pump to ensure the stability of the magnetic steel.

3 Product Features
The CQ corrosion-resistant stainless steel magnetic pump has an input medium temperature of -15~+100 ℃, made of stainless steel, with a density not exceeding 1600kg/m3, a suction pressure not exceeding 0.2Mpa, and a working pressure of 1.3Mpa. It transports liquids without particles and fibers.
4 Product Usage
CQ corrosion-resistant magnetic pump is used for corrosive liquids that do not contain solid particles, strong acids, strong bases, ethanol, bleaching agents, photographic fluids, nitric acid, hydrochloric acid, hydrofluoric acid, acetic acid, sodium hydroxide, acetone, ethylene oxide, seawater, saltwater, and so on.
Note: If the medium temperature is high (above 150 ℃ is considered high temperature), customers must consider high-temperature resistant magnetic pumps, otherwise unnecessary trouble may occur.
5 working principle
CQ corrosion-resistant stainless steel magnetic pump consists of three parts: stainless steel pump, magnetic transmission, and electric motor. The key component of the magnetic transmission is composed of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, driving the inner magnetic rotor connected to the impeller to rotate synchronously, achieving non-contact transmission of power and transforming the dynamic seal into a static seal. Due to the complete sealing of the pump shaft and inner magnetic rotor by the pump body and isolation sleeve, the problems of 'running, emitting, dripping, and leaking' have been completely solved, eliminating the safety hazards of flammable, explosive, toxic, and harmful media leaking through the pump seal in the refining and chemical industry, effectively ensuring the physical and mental health and safe production of employees. The working principle of a magnetic pump is to arrange n pairs of magnets (n is even) in a regular manner and assemble them on the inner and outer magnetic rotors of a magnetic actuator, so that the magnet parts form a complete coupled magnetic system. When the inner and outer magnetic poles are opposite in polarity, i.e. the displacement angle between the two poles is Φ=0, the magnetic energy of the magnetic system is measured; When the magnetic poles rotate to opposite poles, i.e. the displacement angle between the two magnetic poles is Φ=2 π/n, the magnetic energy of the magnetic system is measured. After removing the external force, due to the mutual repulsion of the magnetic poles in the magnetic system, the magnetic force will restore the magnet to its magnetic energy state. So the magnet generates motion, driving the magnetic rotor to rotate. The type and basic parameters of CQP series stainless steel magnetic pumps comply with the JB/TQ786-89 "Type and Basic Parameters of Small Magnetic Driven Centrifugal Pumps" standard and the "Supplementary Provisions for Three Standards of Small Magnetic Driven Centrifugal Pumps".
