White Peony Tea belongs to White Tea,one of the six tea categories in China, which is famous for its silvery green leaves with silvery white heart, which looks like flowers. The shape of white peony has a fat shape, its leaves are plump and tender, and its leaves are grey-green. Fresh and tender after brewing; Taste mellow and slightly sweet; Soup color apricot yellow bright or orange yellow clear; The leaf base is tender and well-balanced, and the pulse is reddish. It has the effect of nourishing lung and clearing heat, and is often used medicinally.

Before starting the centrifugal pump, the valve should be closed. After the start, when the motor is running normally, it is necessary to slowly open the valve and gradually increase the power to the rated power.
In the course of use of the centrifugal pump, sometimes the conditions of use have changed. For example, during the winter dry season or when the tide is low, the water level of the river drops; sometimes the requirements for use change, and there are different requirements on the flow rate and lift in the production. The valve can be used to regulate the performance of the pump. Adapt to new usage conditions and requirements.
Therefore, a well-equipped centrifugal pumping device should install a gate valve on the outlet pipe.
Why should a valve be installed on the outlet pipe of a centrifugal pump? How to operate correctly?
According to the flow-power curve of the performance curve set of the centrifugal pump, it represents the change rule of the relationship between flow and power, which is a smooth curve that gradually increases with the increase of flow. That is, under a certain speed, the water pump shaft power increases with the increase of the flow rate, and decreases with the decrease of the flow rate. When the gate valve on the outlet pipe is closed, the flow rate of the water pump is equal to zero. At this time, the power of the water pump shaft reaches a minimum value, which is the safest for the supporting power machine, and is especially safe for the motor because the motor starting current is 6 times the normal operating rated current. Therefore, if the centrifugal pump is started by opening the valve, the motor is easily burned. The centrifugal pump is suitable for shutting off the valve, and the power consumption of the water pump shaft is minimum, and the motor protection is the best. It will not be burned due to the load starting and the current is large.
