ZCQ type self-priming magnetic drive pump (hereinafter referred to as self-priming pump) uses static seal instead of dynamic seal, so that the flow passage parts of the pump are in a completely sealed state, which completely solves the unavoidable problems of running, emitting, dripping and leaking of other pump mechanical seals. The pump body and flow passage parts are made of corrosion-resistant stainless steel, corundum ceramics, tetrafluorographite and other materials, It not only has the function of CQ type magnetic drive pump, but also integrates self-priming. It doesn't need bottom valve and irrigation water. The self-priming height is 4m.
ZCQ type self-priming magnetic pump adopts the structure of external mixing axial return water pump body, which is composed of liquid suction chamber, liquid storage chamber, volute, return hole, gas-liquid separation chamber, etc. After the pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the liquid inlet pipeline are stirred by the impeller to form a gas-water mixture. The mixture enters the gas-liquid separation chamber through the volute. As the speed slows down, the gas-water separation occurs. The air is discharged from the liquid outlet of the pump, and the liquid returns to the pump through the return hole. After repeated circulation, the air in the liquid inlet pipeline is discharged, Make the pump form a certain degree of vacuum, to achieve the role of self-priming.
It is suitable for conveying large pressure of 1.6Mpa, temperature of no more than 120 ℃ and viscosity of no more than 30 ℃ × 10-6m2 / s liquid without ferromagnetic particles and fibers. When the pressure of the conveying medium system is more than 1.6Mpa, the temperature is more than 120 ℃, and the supporting insulation measures are needed, the unit can carry out special design and manufacture.
Performance range: (rated point)
1. Flow: 0.8 ~ 120m3 / h
2. Lift: 5 ~ 80m
3. Power: 0.37 ~ 55kW
4. Kinematic viscosity of medium: ≤ 32 * 10-6m / S
5. Medium temperature: - 20 ~ 120 ℃
1. The pump shaft is changed from dynamic seal to closed static seal to avoid medium leakage.
2. The self-priming magnetic pump does not need independent lubrication and cooling water, which reduces energy consumption.
3. From coupling drive to synchronous drive, there is no contact and friction. It has low power consumption, high efficiency and damping effect, which reduces the influence of motor vibration on pump and cavitation vibration on motor.
4. When the self-priming magnetic pump is overloaded, the inner and outer magnetic rotors slide relatively, which has a protective effect on the motor and pump.
ZCQ self-priming magnetic pump has compact structure, beautiful appearance, small volume, low noise, reliable operation and convenient maintenance. Self priming magnetic pump can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photo printing, scientific research institutions, national defense industry and other units pumping acid, lye, oil, rare and precious liquid, transition liquid, volatile liquid, and circulating water equipment. Especially for flammable, explosive and volatile liquid, this pump is more ideal.
