00 The invention relates to equipment for gas-dynamic installations, mainly vacuum pumps of paper machines, and can be used in the pulp and paper industry. A water separator is known, consisting of a horizontal inlet pipe, a resonant chamber and a horizontal outlet pipe on which a noise trap has been installed. . The drainage pipe is fitted with a cap and is a vertical pipe with a free passage of fluid. 1 The water separator provides some reduction in the level of noise from the pump exhaust. However, due to the fact that the WATER RELEASE nozzle is loose with a free passage for a liquid, it creates the possibility of sound energy out of the chamber, which significantly reduces the efficiency of the secondary separator. A water separator for vacuum pumps of papermaking machines is also known, which contains a chamber with inlet, gas and drainage pipes and means for adjusting the level of liquid installed in the vertical drainage pipe. The water-air mixture through the suction inlet enters the chamber, where aa water and air are separated. The liquid under the action of gravity drops and accumulates to the level of the upper edge of the drainage pipe. Transfusion, it is retracted downwards and encounters a diaphragm in its path, whose position is adjustable in height, which provides sound insulation for various working conditions. 2 However, when changing to another mode, a special additional adjustment is necessary. The purpose of the invention is to automatically maintain the level of a liquid when the operation mode is changed to ensure effective sound insulation. This goal is achieved by the fact that the means for regulating the liquid level of the water separator, mainly for the vacuum pumps of a paper machine containing a chamber with inlet, gas and drainage pipes and means for regulating the liquid level installed in the vertical drainage pipe, is in the form of freely mounted312 flap impeller located in the lower part of the drainage pipe. FIG. 1 shows a water trap general view; in fig. 2 is a view along arrow A in FIG. 1. The device contains a resonant chamber 1, in which a receiving branch pipe 2, an air outlet pipe 3 and a WATER CONNECTING 4 are fastened. The impeller 5 is made in the form of a circle divided into sectors, the angle of inclination of which to each other depends on the diameter of the nozzle. The device works as follows. The water / air mixture through the receiving pipe 2 enters chamber 1, where it is separated into liquid and water. The liquid of the leopard by the force of gravity falls and enters the nozzle 4. Meeting on the way Kpbmb4atKy 5, the water fills the entire nozzle and, acting on the impeller, forces it. rotate. When the impeller 5 rotates, the water passes through the slits of the latter. The impeller resistance ensures a constant level of water in the nozzle in varying modes. For example, as the amount of water withdrawn increases, the pressure on the impeller increases, thereby increasing the rotational speed of the impeller, and consequently, the volume of the withdrawn liquid increases. Depending on the diameter of the nozzle 4 to maintain a constant height of the water level in the nozzle, the angle of inclination of the blades changes (with an increase in the diameter of the nozzle, the angle of inclination decreases, since at such an angle of inclination the speed is necessary to maintain a constant water level). Compared with the prototype, the proposed water separator provides automatic adjustment of the fluid level when changing to another mode and changing conditions of pump operation. The proposed water separator does not require additional costs of electricity. When installing it on a vacuum pump, for example HB-03, the last
