Abstract

The invention relates to the field of pump construction, in particular, to replacement pumps. The aim of the invention is to reduce energy consumption by using the energy of the exhaust gas in a gas replacement cycle. In the pneumatic replacement pump, the working chambers 1 and 2 communicate with a fluid source by nozzles 3 supply with non-return valves 5, and with a liquid consumer - by nozzles 4 outlet with non-return valves 6. Alternating communication of working chambers 1 and 2 by distributor 7 with diffuser 13 of injector 8, reported an active nozzle 9 with a pressure pipe 10, and with a discharge pipe 12 connected to the passive nozzle 11 of the injector 8, allows the flow of compressed gas that produced a replacement cycle in one of the working chambers to another rshenny in it a replacement cycle. To ensure the filling of the working chamber in which the replacement cycle has taken place, the replacement pump is equipped with a check valve 14 installed in the discharge pipe 12, communicated by its inlet with the distributor 7, and the outlet with the passive nozzle 11, and the discharge valve 15, communicated by the input 16 s the outlet pipe 12 before the inlet of the check valve 14, the outlet 17 with the atmosphere, and the control channel 18 with the outlet pipe 12 after the return valve 14 exits. 1 Cp. f-ly, 2 ill. with (/) th /;

Description

The invention relates to a pump. with groin, in particular for pumps; substitution.

 The purpose of the invention is to reduce energy consumption by using the energy spent in the gas mixing cycle.

I FIG. 1 shows a diagram of a pneumatic replacement pump; FIG. 2 shows a circuit for connecting the control channel of the discharge valve to the discharge pipe. The pneumatic replacement pump comprises a series of working chambers 1 and 2 with inlet pipes 3 and a drain of 4 liquids with non-return valves 5 and 6, a distributor 7 connected to the working chambers 1 and 2 , injector 8, having an active nozzle 9, connected by a pressure pipe 10 with a gas pressure source, a passive nozzle 11, communicated by a discharge pipe 12 with a valve 7, diff; iop 13, a reverse valve 14, installed by jjieHHbrii in the discharge pipe 12 And report It is supplied with its input with the distributor 7, and the output with the passive nozzle 11, and the unloading valve ijiaH 15, communicated with its input 16. The outlet pipe 12 before the 1 return valve stroke 14, the outlet 1 with the atmosphere, and the control channel 18 - with the outlet pipe 12 after the return valve fla 14. The diffuser 13 communicates with the working ijtH cameras 1 and 2 through the distribution Eating 7. In addition, the end of channel 19

8 unloading valve controls

5 may be located inside the outlet pipe 12 and its inlet 20 faces toward the passive nozzle.

The pneumatic replacement pump operates as follows.

After the replacement process in one of the working chambers 5, for example in the working chamber 1, the distributor 7 manages to a position in which the diffuser 13 of the injector 8 communicates with the working chamber 2. pre-filled with fluid, while the passive nozzle 11 communicates with the working (Samara 1. Compressed gas from the source of gas pressure and from the working chamber 1 is directed to the working chamber 2, the injector 8 is used to force the compressed gas from the working chamber 1.

When the gas pressure in the working chamber 2 is increased to a value close to the value of the gas pressure at the inlet of the injector 8, the gas is directed through the passive nozzle 1-1 to the discharge pipe 12, while the check valve 14 is also closed by the pressure of the gas flowing through the control channel 18, the discharge valve 15 is switched, the working chamber 1 is in communication with the atmosphere. The gas pressure in the working chamber 1 is reduced to atmospheric pressure and the working hours of the chamber 1 are filled through the inlet 3 of the inlet and non-return valve 5 with liquid.

Under the action of the pressure of the gas entering the working chamber 2, the liquid from this chamber is directed to the consumer through a check valve 6 through the outlet 4. When the liquid level in the working chamber 2 drops to a certain level, the distributor 7 switches and the working chamber 1 communicates with the pressure source, and the working chamber 2 is connected to the discharge pipeline 12. Next, the replacement process in the working chamber 1 occurs similarly to the replacement process in the working chamber 2 After the completion of the replacement process in the working chamber 1, the cycle is repeated.
