Ptdpressure sewage pumping station according to claim 3. The sewage system according to claim 1, characterized in that the sewage line / 3 / of the pressure-pressure sewage system / 1 / is placed below the lowest level of the sewage table with a reservoir / 2 /. * * * The subject of the invention is a vacuum sewage pumping station, especially with an automatically regulated height under pressure applied to various types of sewage systems. There is a known sewage pumping station, the main element of which are hermetically sealed sewage tanks, i.e. vacuum chambers. These tanks are placed vertically above the sewage pumps, and above the tanks there are vacuum pumps. The negative pressure created by vacuum pumps in the vacuum chambers causes the leakage of sewage from the sewage system to these chambers. From the chambers, the sewage flows to the sewage pumps located below, from where it is directed to, for example, a sewage treatment plant. The disadvantages of this type of pumping station are: the necessity to construct void walls of air-tight concrete, high consumption of reinforced concrete and high staff qualifications. The abovementioned principles are distinguished about the pressure pump station of the sewage being the subject of the invention. This pumping station consists of three mutually connected circles ^ yg ^^ and placed one above the other, an automatic system controlling the pumping station's operation is located on the upper and middle storey, while on the lower storey there are sewage tanks and a sewage pump station, directing sewage to e.g. . sewage treatment plants. Above the upper storey, there is a hermetic air-tight tank connected to the central heating vacuum pump located on the upper storey, and with a vacuum sewage system through a venting conduit. The negative pressure sewer line, which is usually located at the level of the upper and upper tiers, also leads to the open wastewater tank located at the lower tier, with the corner of the sewage passage, i.e. the waste water line is below the minimum level of the waste water in the tank. The sewage reservoir is connected to the open space, it is anticipated that the amount of sewage in the reservoir will be increased by flowing to the outside of the pumping station, and then it will flow to the reservoir. Vacuum pump 157 886 located in the upper storey, apart from a hermetic expansion tank, it also cooperates with an electro-fluid control system and so on. closed water tank. The electronic control system consists of a PVC pipe with a fixed float inside. The pipe is preferably half filled with water and is connected with a steel bar, i.e. an open regulating water reservoir, preferably wet in the middle tier, and an airtight equalizing tank. Moreover, the pipe on its outer surface has two electronic inductive sensors cooperating with the vacuum pump, and these sensors can be freely moved on the plane in relation to each other, so that there is always a float placed between them in the inner pipe. If the pressure in the sewage system decreases, then the steel float in the pipe will expand downwards towards the appropriately set lower electronic inductive sensor, causing the vacuum pump to be turned off, the same will happen when the pressure in the sewage system increases - then the float will move to the upper sensor, causing the the vacuum pump is off. The so-called silt tank for this water cycle is wet. It is preferably in the upper stage, its task is to protect the proper operation of the vacuum pump. The main advantage of this type of sewage pumping station is high efficiency and a very high degree of reliability, ease of use, simplicity in implementation. The automatic control system of the pumping station has a variable control range depending on the amount of sewage and the hydraulic resistance of the network. Object of the invention It is presented in the exemplary embodiment in the enclosed schematic drawing, in which the side of the vacuum sewage system 1 enters the upper cladding and the pumping station, where it is connected to a hermetic equalizing tank 5 via a drainage pipe 4, and further leads to an open waste water tank in the bottom column III pumping station. The end of the sewage inlet 3 of the sewage pipe 1 is located below the minimum sewage level in the tank 2. Moreover, the tank 2 is connected to the open space by a discharge-watering pipe 6, and by a suction pipe 8, which is in turn, it is provided with a sewage inlet end 7 with a sewage pump 9 which pumps the sewage to e.g. a treatment plant by means of a pressure line 10. The automatic system located on the 1st floor of the pumping station is equipped with a pipe 13 connected on the one hand to the airtight air reservoir 5, and on the other hand, by means of a tube 12 to an open reservoir of regulating water 11. On the outer part of the pipe 13, two electronic inductive sensors 14 are arranged, they are arranged on the pipe 13 in such a way that inside the tube 13, a float 15 is provided between them. Sensors 14 cooperate with a vacuum pump 17 which is connected to a hermetic tank f and through the air pressure conduit 18 with a circulating water tank 19 provided with an air / vet ejector 20. The tank 19 ensures proper operation of the vacuum pump 17.
