Description

Hydraulic positive displacement pump

The utility model relates to hydraulic engineering and land reclamation and is intended for the intake and supply of water from the downstream of ponds and small-capacity reservoirs.

Known volumetric diaphragm pump driven by a gaseous working medium, consisting of a housing, two membranes, a pump chamber with pressure and pressure valves, drive chambers, supply pipes

discharge, rigid center, flow line and control throttle

A disadvantage of the known pump is the relative complexity of the design.

Closest to the claimed utility model is a hydrodynamic positive displacement pump, consisting of a supply pipe, a chamber with a membrane and a rigid center, a suction valve and a cylinder hermetically attached to a rigid center, a fixed housing with a discharge valve, an air cap and a charge-discharge device in the form of a siphon , tanks and tubes for breaking the vacuum in the siphon. 2.

The disadvantage of this device is the low speed of the charge-discharge device due to the long period of charging the siphon.

The problem to be solved by the claimed utility model is to create a hydrodynamic positive displacement pump, the technical result of which is to increase the speed and action of the charge-discharge device.

The technical result is achieved in that in a hydrodynamic volumetric pump, consisting of a supply pipe, a chamber with a membrane and a rigid center, a suction valve and a cylinder, hermetically sealed ... I,

de hermetically attached coaxially to the hole to the bottom of the chamber with a membrane of a cylindrical nozzle, a hollow body, which is integral with the suction valve, a flap with a flange and thread, a relief valve that blocks the hole. The stem has the ability to move vertically inside the hollow body, the nut of the hollow body limits the movement of the stem.

In FIG. 1 shows a diagram of the device of the proposed hydrodynamic displacement pump, in FIG. 2 - stem I in FIG. 1. “.. Hydraulic positive displacement pump connects to the water

construction 1 by means of a valve 2 and consists of a supply pipe 3, a chamber 4, formed by the housing 5 and hermetically connected to it by a membrane with a rigid center 6, cylinder 7, which is integral with the rigid center. The rigid center 6 has an opening 8, which is blocked by the suction valve 9. The disk 10 with the hole 11, which is blocked by the discharge valve 12, is hermetically connected to the lower edge 13 of the stationary cylinder 14, which is integral with the air cap 15. The housing 5 of the chamber 4 is connected to the atmosphere a hole 16 and a cylindrical nozzle 17 which is hermetically attached to the bottom of the chamber 17. The hole 16 is blocked by a relief valve 18 fixed to the thread of the rod 19, which moves vertically inside the hollow body 20, the suction valve 9, and the movement of the rod 19 is limited nut 21 hollow body 20 and the flange 22. Installation of the opening of the relief valve is provided by moving the relief valve 18 to the rod 19 and lock nut 23.

The operation of the hydraulic volumetric pump is as follows. When the valve 2 is opened, a stream of water fills the chamber 4 and enters through the opening 8 into the discharge chamber. As the chamber 4 is filled, the membrane with a rigid center 6, a cylinder 7, a suction valve 9 with a hollow body 20 of the suction valve 9 moves upward under hydrostatic pressure and the suction valve 9 closes from the back pressure in the cylinder 7, and the discharge 12 opens and water from the cylinder 7 is forced into the air cap 15 and from it into the discharge pipe. When the maximum pressure in the cylinder 7 is reached, the flange 22 of the rod 19 abuts against the nut 21 of the hollow body 20 and the rod together with the relief valve 18 mixes upward, opening the discharge hole 16. Water from the chamber 4 is discharged through nozzles 17 into the downstream end; the pressure in the chamber 4 drops, the membrane with a rigid center 6, a cylinder 7, a suction valve 9 with a hollow body 20 is mixed; it is pressed down under the influence of a special weight of 6 N. The cycle repeats.

The application of the proposed device will significantly increase the speed of the hydrodynamic volume pump.
