(54) - CAPACITOR OF COOLING LIQUID TO CAPACITOR (57) The invention relates to the field of pumping and allows to increase the reliability of the system in operation by reducing the dynamic loads on the pump during starts and stops. A supply pipe 2 with a siphon 3 connects the lower part of the condenser (K) 1 with a pump 4. The air removal device from K 1 is made in the form of an ejector 5. An air clan is installed in the upper part of K 1. An additional pipe 7 connects the upper part of the siphon 3 to the top of K 1. The system prevents the formation of trapped air in the siphon during start-up, evacuating the air released from the liquid from the siphon during operation, prevents the pipe 2 from siphoning and reduces the load on the pump. when you stop. 1 il.

The invention relates to a pumping system, in particular, to cooling systems of a condenser in a power plant.

The purpose of the invention is to increase the reliability of operation by reducing the dynamic loads on the pump during starts and stops.

The drawing shows the principal device sche.

The coolant supply system I to the condenser 1 contains a supplying I pipe 2 with a siphon 3, a pump 4, a device for removing air from the condenser 1, performed as an ejector 5, and an air valve 6, while the system is equipped with I wife with an additional pipeline 7 connecting the upper part of the siphon 3 with the upper part of the capacitor I.; System - works as follows. : After switching on the pump 4, the liquid is supplied to the supply pipe 2 and si-i (j) OH 3. At the same time, the air from the piping 2 and siphon 3 is pressed into the con-: Capacitor 1 through the pipeline 7 to the vertical section of the pipeline 2. From the condenser I, the air is partially removed by the ejector 5, partly - the air flow valve is squeezed out;

When it stops, the liquid from the condenser 1 is drained through the pump 4. At the same time, the air valve 6 is opened and the vacuum in the condenser 1 is broken. At the same time, the atmospheric pressure is supplied through the pipeline 7 to the siphon 3, which leads to the breakdown of the vacuum in it.

The proposed system eliminates the formation of trapped air volumes in the siphon 3 at start-up, evacuates the air released from the liquid from the siphon 3 during operation, and prevents pipeling 2 from siphoning and reduces the load on pump 4 when it stops.

Claims (1)

Claims of the invention. A coolant supply system to a condenser, comprising a supply pipe with a siphon, a pump, a device for removing air from the condenser, and an air valve installed in the upper part of the condenser, which in order to improve the reliability by dynamic loads on the pump when it starts II stops, the system is equipped with an additional pipeline connecting the upper part of the siphon with the upper part of the condenser.
