Abstract

The invention can be used to pump various fluids. The aim of the invention is to increase productivity by reducing the time to discharge gas from the housing. The pump includes a housing (K) 1 with a float (P) 2 placed inside it, made in the form of a variable section vessel, suction and discharge nozzles 3,4 with valves 5,6 and a drain valve (DK) 7 equipped with a permanent magnet 8. P 2 is constricted in the upper part, the constriction height δ being determined by the relation δ≥F _d.k / ϕ ^. D _dk [1+ (D _v.p / D _to -D _vp )], where F _dk is the area of the flow area DK 7

D _BC to the diameter of the flow area of the DC 7

D _VP - the outer diameter of the constriction in the upper part of the P 2

D _k is the inner diameter of K 1. K 1 and the internal cavity of P 2 are filled with liquid, then P 2 sinks and DK 7 closes, K 1 is filled with compressed gas and the liquid is displaced from it. After emptying the P 2, it floats up, while DC 7 opens to the required height. 1 il.

The invention relates to pumping and can be used for pumping various liquids.

The purpose of the invention is to increase productivity by reducing the time to discharge gas from the housing.

the internal cavity of the float 2 is empty, the float 2 floats, and the drain valve 7 opens. Making the float 2 constricted in the upper part allows, along with an increase in the speed of raising the float. The drawing shows a pump, about 0 to its original position, its general appearance.

Claims (1)

Invention Formula A pneumatic replacement pump, comprising a housing with a float placed in it in the form of a variable-section vessel, suction and discharge nozzles with kPA panels and a drainage valve equipped with a permanent magnet, characterized in that gas discharge from the housing, the float is made tapering in the upper part, and the height of the narrowing is determined by the ratio where is f al 3 D .to. bp the bore area of the drain valve; the bore diameter of the drain valve; the outer diameter of the constriction in the upper part of the float, D - the inner diameter of the housing The pump works as follows. Under the action of hydrostatic pressure, the housing 1 and the internal cavity of the float 2 are filled with the pumped liquid, after which the float 2 sinks and the drain valve 7 closes. After filling the housing 1, it is started to be pressurized with compressed gas, and the liquid is displaced into the suction 50 Dedicated nipple 4. Body 1 and Compiled by A.Kuligin Editor M.Kelemesh Tehred M.Hodanich the internal cavity of the float 2 is empty, the float 2 floats, and the drain valve 7 opens. Making the float 2 tapering in the upper part allows, along with an increase in the speed of raising the float to its original position, to ensure 0 five 0 bake and the required height ascend, i.e. lift height of the drain valve 7.
