(54) PISTON INERTION PUMP

one

This invention relates to piston inertial pumps for pumping corrosive media.

A piston inertial pump is known, which contains a spring-loaded piston, which is disposed inside a hermetic center-tube, outside of which there are flexible pipes for supplying and supplying the pumped medium and driving a cylinder. Pumping and sucking feeds are carried out by varying the volume of the chamber between the piston and the cylinder walls with a frequency exceeding the natural frequency of the piston.

The disadvantages of the known agglomeration include: low pump performance, large feed ripple and large cylinder drive dimensions.

The aim of the invention is an increase in productivity with minimum dimensions and a reduction in the flow rate of the piston inerodon pump.,

This is achieved by the fact that, in the proposed piston inertial pump, several cylinders are tio circumferences parallel to the axis of the drive shaft and pivotally connected to two end inclined discs driven by

noun movement, for example, by means of VH. on the rotating washer. Cshshidry contain floating pistons, are equipped with suction and discharge valves and are connected by flexible pipes to the suction and discharge lines through a manifold in the pump casing.

To reduce shock loads, cylinders are equipped with hydraulic demipffers.

The drawing shows the proposed piston TH inertial pump, a longitudinal section.

In the ilacoca housing 1 there is a block of axially 1-spaced sealed cylinders 2, inside of which are floating pistons 3. In the face parts of each cylinder there are suction 4 and pressure 5 valves.
