Movement Rule of Deep Well SubmersiblePump Valve

Deep well submersible pump valve's motion law in addition to the linear motion of the vertical direction, and is accompanied by two kinds of rotary motion. When the piston velocity is small, the valve ball level weeks rotate; When the piston velocity is larger, the valve ball around the week of vertical horizontal biography and the hole edge horn is along the seat seat hole center axis of revolution. The rotating angular velocity is associated with the rate of movement of the plunger, the plunger speed, the greater the valve ball rotation angular velocity. The greater the special movement form the main valve ball and valve seat structure particularity and the impact of the fluid. Deep well pump valve is a ball valve, when the fluid around it activities, behind will occur from the phenomenon of boundary layer, at the same time produce a lateral move. Because of the symmetry valve ball, the lateral exciting force move along the valve ball near the equator of the cycle, the valve ball is not always located in the seat hole axis line. But deviate from an interval and tight against the seat edge rotation, this is the phenomenon of revolution.

Not disorderly fluid activities and relative deviation caused by fluid of valve ball valve ball activity differences, according to the error of valve ball will produce certain scratched, the transverse force is not applied to its. But in the horizontal plane and there is a certain eccentricity, the valve ball in the horizontal plane and a rolling, this kind of phenomenon is called an autobiography.
