What factors affect the efficiency of acid and alkali resistant magnetic pumps?

　　Acid and alkali resistant magnetic pump has been widely used in a variety of liquid chemical transportation, as a production enterprise, to what structure, configuration to produce anticorrosive pump products, different structural forms and configurations, will give customers different use effect.

　　Acid and alkali magnetic pump magnetic coupling and pump body combined into one, so the structure is compact, easy maintenance, safety and energy saving, the pump's magnetic coupling can play the role of overload protection of the drive motor, acid and alkali magnetic pump work efficiency is the pump casing machine commandment, capacity and water conservancy the product of several rates, the rate of the pump group is the product of the pump rate and the rate of the electric motor.

　　It can be concluded that the main elements affecting the working efficiency of acid and alkali resistant magnetic pump contain:

　　1. Before the pump starts, employees do not pay attention to the centrifugal pump before starting the preparatory work, warming the pump, disk pumps, filling pumps and other basic operating procedures are not thoroughly implemented, often resulting in pump cavitation phenomenon, resulting in pump noise, vibration, pump efficiency is low.

　　2. The impact of mechanical efficiency is mainly related to the design and manufacturing quality. Motor efficiency in the use of basic to remain unchanged. Therefore, select a high-efficiency motor to the critical importance. After the pump is selected, the later management has less impact.

　　3. Pump volume loss, also known as leakage loss, including impeller sealing ring, between stages, axial force balance mechanism of three kinds of leakage loss. Volumetric efficiency is not only related to the design and manufacture, but also related to the later management. Pump continuous operation for a certain period of time, due to friction between the components, the gap increases, the volumetric efficiency decreases.

　　4. The efficiency of the chemical pump itself is the fundamental impact. The same working conditions of the pump, the efficiency may differ by more than 15%. Centrifugal pump operating conditions below the rated working conditions of the pump, low pump efficiency, high energy consumption.

　　5. Hydraulic losses including hydraulic friction and local resistance losses. After the pump runs for a certain period of time, it inevitably causes the surface wear of the impeller and guide vane and other parts, the hydraulic loss increases and the hydraulic efficiency decreases. The centrifugal pump pumping and idling is caused by the clogging of the filter cylinder and the intake of air in the pipeline.

　　Acid and alkali resistant magnetic pump relies on the magnetic coupling to transfer the torque. For the magnetic coupling, the large torque that can be transmitted is constant, when it is subjected to load torque exceeds its zui large disengagement torque, the magnetic coupling will disengage, resulting in a sharp increase in eddy currents in the metal isolation sleeve, the magnet temperature rises resulting in demagnetization to the point of not being able to use the magnetic pump of the magnetic transmission of the design of the torque in a large portion of the torque is to overcome the inertia at the time of the start-up.

　　1, magnetic pump vacuum or deceleration will cause a reduction in the rate;.

　　2, the equipment itself, the same working standard, the rate will be about 15% apart;.

　　3, corrosion-resistant magnetic pump is less than the power load work, the pump efficiency is low, energy consumption will be higher; 4, the rate of the motor in the application of the magnetic pump will be lower than the power load work.

　　4, the rate of the motor in the application of the basis to remain unchanged, and therefore should be selected as far as possible for each high efficiency motor.

　　5, the sliding friction of the water will be effective in the wind wheel surface layer, and then work time will produce damage, jeopardize the working efficiency.

　　6, mechanical efficiency is also related to the arrangement of production quality. So pick a good pump, the end of the regulatory harm is less; 7, the capacity of the equipment damage alias the wind turbine.

　　7, the capacity of the equipment damage, also known as leakage damage, including wind turbine seals, interstage, radial force equalization organization of several kinds of leakage damage. Capacity rate of high and short not only with the arrangement of production, but also with the end of supervision. After the pump continues to operate for a certain period of time, because of the friction between the components, the gap expands, and the capacity rate decreases; 8, corrosion-resistant magnetic pumps start up.

　　8, corrosion-resistant magnetic pump before the start of the intention to do, many people to the application of the process, do not pay attention to the intention to do, the basic intention contains: warm pumps, disk pumps, etc., can reduce the turbidity caused by the ability to reduce the noise of the pump to enhance efficiency.
