Abstract

The invention makes it possible to increase the efficiency of a pump for pumping fluids. The diaphragm 10 is installed in the housing 1 with the formation of the pumping and explosion chambers 2.5. In the chamber 2 valves are installed. Chamber 5 is equipped with pipelines 6.7 fuel supply and oxidant, nozzle

Description

Kami 8 and 9 ignition source. The diaphragm 10 is tubular. Valves 3,4 are located in partitions 11, 12 located at the ends of the diaphragm 10. The chamber 5 is made annular and is provided with a radially arranged pipe 13 with a flange 14 and a movable spring-loaded arm 1 5. The cover 15 is equipped with an exhaust gas discharge valve 16 and a shoulder 17, covering 9281

branch pipe 13 with the formation with the flange 14 of the closed cavity 18-. A spring 19 is installed in the cavity 18. A diaphragm tank 20 is installed in the chamber 5 and communicates with the cavity 18 between the flange 14 and the collar 17. The presence of spring-loaded tongs 15 leads to an increase in pressure wave over time. 1 il.

The invention relates to pump construction, diaphragm explosion pumps and can be used in various industries of the national economy for pumping fluids.

The purpose of the invention is to increase the efficiency of the pump.

The drawing shows the proposed pump.

The pump includes a housing 1 in which, with the formation of a pump chamber 2 with valves 3 and 4 and an explosive chamber 5 with a system for filling with combustible mixture (pipes 6 and 7, respectively, fuel and oxidant supply and nozzles 8) and ignition source 9, a diaphragm 10 is installed. tubular, valves 3 and 4 are located in the partitions 11 and 12, placed at the ends of the diaphragm 10, and the explosion chamber 5 is annular and provided with a radially located pipe 13 with a flange 14 and a movable spring-loaded lid 15, A valve 16 for discharge of exhaust gases and a collar 17 encompassing a nozzle 13 -c formation of a closed cavity 18 with a flange 14, in which a spring 19 is installed, and a damping tank 20 installed in the explosion chamber 5, connected to the cavity 18 between the flange 14 of the nozzle 13 and the shoulder 17 cover 15. Valve 3 is suction, and valve 4 is discharge. The cavity 18 and the container 20 are filled with fluid.

The combustible mixture is fed in portions through pipelines 6 and 7 to the nozzles 8 and injected into the explosion chamber 5,

The ignition source 9 ignites the combustible mixture and in the explosion chamber 5 there is no explosion accompanied by an increase in the pressure of the combustion products. 5; At the same time, the rim 15 is raised, compressing the spring 19, which leads to an increase in the volume of the explosion chamber 5 and smoothing the shock wave. This provides more favorable conditions for the deformation of the diaphragm 10. The volume of the pumping chamber 2 when the diaphragm 10 is compressed decreases, and the pumped medium

displaced through the pressure valve 4 to the consumer.

When the cover 15 is lifted, the fluid from the cavity 18 flows into the container 20 o. This ensures damping of the oscillations of the cover 15. After the combustible mixture is completely combusted, the combustion products are released from the chamber 5 through the valve 16, the pressure in the chamber 5 drops, the cover 15 returns to the original 19 put5

0

and the diaphragm 10 takes on its original form, as a result of which the volume of the pump chamber 2 increases and a new portion of the pumped medium is sucked in through valve 3.

Then the cycle repeats.

Stretching the pressure waves in chamber 5 over time increases the efficiency of the pump.
