Flow control method of small pump:
When many users use small pumps, they need to adjust the flow because of the excessive flow of the pumps. In the past, they used to adjust the flow by lowering the voltage or adding valves, which brought a lot of inconvenience to the use.
Small pumps are water-gas dual-purpose pumps. They are upgrading products of WKY series. Besides better performance and longer service life, the greatest features of this series are: adjustable flow rate of pumps. Their advantages are as follows:
1、Brushless motor, long life, low interference. It can operate continuously day and night without disturbing the surrounding electronic components and polluting the power supply.
2、It can not only pump water directly, but also pump air. It belongs to the dual-purpose pump of water and air. It can self-priming, but also can "dry turn".
3、For simplicity and convenience, it can be equipped with the pump speed control box of Xinweicheng Company. By inserting the wiring of the pump motor directly into the speed control box, the flow rate of the small pump can be changed by rotating the button on the speed control box to change the speed of the motor.
4、 Feedback signal of motor speed。 From this, we can know the running state of the pump, which is convenient to realize closed-loop control and make the system more intelligent。
5、 Overheat protection and overload protection: For example, accidents may lead to abnormal temperature rise of the pump motor, small pumps will automatically protect the shutdown to avoid motor burning; if foreign bodies fall into the motor, they may be stuck, and the pump will automatically protect the shutdown to avoid motor burning;
6、Maintenance-free, oil-free and non-polluting working media.
