What are the flow adjustment methods for acid and alkali resistant chemical pumps?

　　Acid and alkali resistant chemical pumps are pumps that can work normally in strong acid and alkali media, they are corrosion resistant, abrasion resistant, high temperature resistant, high flow rate, small size, etc. Due to their special working environment, when using these pumps, corresponding measures must be taken to ensure their normal operation, and flow regulation is one of the important aspects.

　　What are the ways to adjust the flow of acid and alkali chemical pumps?

　　First of all, the flow regulation of acid and alkali chemical pumps are: speed regulation, impeller opening regulation and control valve regulation.

　　Speed adjustment refers to the motor and pump installed between the control device, by changing the speed of the motor to change the flow of the pump, this way will have a certain noise, but can be a better control of the flow, is currently more commonly used flow adjustment.

　　Impeller opening adjustment refers to change the opening of the impeller in the pump, so as to change the flow of the pump. This way can be very fine control of the flow, but need to consume a certain amount of energy, and the impeller will be damaged.

　　Finally, the control valve adjustment, it refers to the control valve installed in the pump outlet, change the opening of the control valve to change the flow of the pump, this way of high efficiency, easy to operate, can control the flow very well, is currently the most used way of flow regulation.

　　Acid and alkali chemical pump flow adjustment methods have the above three, different pumps may use different ways, before use need to choose the most appropriate way according to the actual situation, in addition, in the use of acid and alkali chemical pumps, in addition to the flow adjustment, but also need to pay attention to the correct installation of the pump, the discharge of the medium is clean, to prevent the contamination of impurities, to limit the flow, to maintain the normal operation of the pump, to ensure that the pump's long life.
