    Understanding turbidity sensor

    2018-08-29

    The working principle of turbidity sensor sensor: when the light passes through a certain amount of water, the amount of light penetration depends on the amount of dirt in the water. When the amount of dirt increases, the light penetrating the water sample decreases. The turbidity sensor measures the amount of light passing through to calculate the turbidity of washing water.

    Understanding the pump

    2018-08-19

    Delivery pump is a kind of pump which relies on motor to drive the piston to and fro in a sealed body. The one-way valve is used to control the one-way flow of liquid at the inlet and outlet, and the volume change of working space generated in the reciprocating motion of piston is used to transport liquid. The piston pump uses the motor to drive the cam mechanism to drive the piston movement. When the piston moves outwards, the volume of the sealing chamber space increases from small to large, forming a vacuum. The inlet check valve is opened, and the outlet check valve is closed to suck in the liquid. When the piston moves inward, the volume of the sealing cavity space changes from large to small, the outlet check valve is opened, the inlet one-way valve is closed, and the liquid is squeezed into the pipeline. So as to realize the function of automatic delivery.
