Description

one

The invention relates to pump construction and can be used for pumping liquids with inclusions.

The purpose of the invention is to increase productivity by increasing the speed of opening the working chamber.

Figure 1 shows the pump, a general view; Fig 2 - section A-A in Fig.1

The submersible pump includes a housing 1 with central suction and discharge openings 2 and 3. The latter of which is connected to the discharge nozzle 4, mounted in the housing 1 on the axis 5 with a spring 6, two elastic convex disks 7 and 8 that are connected and form they interlock each other with a metric working chamber 9, the discharge pipe 4 is provided with a check valve Yu, the disks 7 and 8 are placed at the outlet of the suction port 2 and pivotally mounted on the axis 5, perpendicular to the axis of the suction port 2, nen a manifold covering the housing 1, and the last performed additional apertures 3. The device also comprises a conduit 11,

The pump works as follows.

Pumped suspension under the action of its own weight through the central suction inlet 2 fills the cavity around the working chamber 9, the discharge nozzle 4 to the check valve 10. The pipeline 11 into the working chamber 9 under pressure supplies a mixture of fuel and air. When the pressure in the chamber 9 is about 0.7-0, -9 MPa, the supply of the combustible mixture is stopped and it is ignited using a spark plug (not shown). The combustion of the mixture takes place in the form of an explosion, as a result, the pressure in chamber 9 increases sharply. Under the action of high pressure, the resilient bulging discs 7 and 8 open like shell valves, /

rotating around the axis 5 and compressing the coil spring 6. The gases, expanding, press the outer sides of the convex disks 7 and 8 to the openings 2, the stronger, the greater the pressure, thereby closing access to the high pressure zone of the pumped suspension. Under the action of a pressure valve Q or not, the check valve 10 opens the suspension outlet through the injection ports 3 and the pipe 4. After the suspension and gas are displaced into the pipe 4, and then the pressure valve drops into the trunk pipe, the check valve 10 closes, and the action of the spring 6. New portion of the suspension through. central suction inlet 2

2Q fills the cavity around working chamber 9, the discharge nozzle 4 to the non-return valve 10. Then the cycle is repeated.
