What is the Principle and operation of heleshaw pump?
The operation of the pump, though a bit complex, is an interesting one. As shown in the figure, the circular ring, which accommodates the slippers is concentric with the central valve arrangement . Due to this, the piston doesn't have any relative reciprocating motion inside the cylinder. No oil is pumped or sucked in and although the pump is rotating no fluid is delivered, during this state. But this is only until the arrangement is concentric. As soon as the circular floating ring is pulled to the right the pistons in the cylinder undergo a reciprocating motion. The lower piston moves inwards and discharges fluid through the lower port. The piston moves till the horizontal position and then moves outwards in the opposite direction, drawing in fluid through the upper ports. Thus in this way the top ports act as suction ports and the lower ports act as discharge ports. If the circular ring is pushed to the left direction, the suction and discharge ports are reversed. All the variable displacement pumps are positive displacement pumps, with a constantly rotating arrangement and a variable discharge design. If the system has more than one pump, a non reversing locking gear is provided, which prevents the reverse operation that might take place at times when only one pump is operating. Moreover, the arrangement is such that as soon as the pump is stopped the locking gear would come into action .
