Heat conducting oil circulating device achieving fast exhausting

Abstract

The invention discloses a heat conducting oil circulating device achieving fast exhausting. The heat conducting oil circulating device comprises a heat conducting oil boiler, a circulating oil pump and a first oil return pipe. A first oil supply pipe is arranged between the heat conducting oil boiler and the circulating oil pump for connection. The heat conducting oil circulating device achieving fast exhausting further comprises an expansion tank, an oil-gas separator is arranged at the tail end of the first oil return pipe, the gas outlet end of the oil-gas separator and the gas inlet end of the expansion tank are directly provided with an expansion pipeline for connection, a second oil return pipe is arranged between the oil outlet end of the oil-gas separator and the oil inlet end of the circulating oil pump for connection, and a third oil return pipe is arranged between the oil outlet of the expansion tank and the oil inlet end of the circulating oil pump for connection. In this way, the heat conducting oil circulating device achieving fast exhausting supplies liquid to the circulating oil pump through the third oil return pipe, exhausting time is greatly shortened, the phenomenon that the circulating oil pump is unstable in pressure and large in air suction and vibration is eliminated, and system safety is guaranteed.

Description

technical field [0001] The invention relates to the field of heat-conducting oil boiler maintenance, in particular to a heat-conducting oil circulation device for rapid exhaust. Background technique [0002] In enterprises that need heat transfer oil for heating, after the heat transfer oil related system equipment or pipelines are overhauled, the air in the system must be removed before restarting operation, so that the system is filled with heat transfer oil to ensure the heat supply and stable operation of the system. [0003] At present, after the system equipment or pipeline maintenance of the heat-conducting oil boiler pipeline system, the air in the system can only be removed through the oil-gas separator, and the exhaust and oil replenishment are all completed in one pipeline, which takes a long time, sometimes as long as 2~ 3 hours, and the pressure of the circulating oil pump was unstable, and the air suction and vibration increased, which affected the normal produ...

AI Technical Summary

Problems solved by technology

[0003] At present, after the system equipment or pipeline maintenance of the heat transfer oil boiler pipeline system, the air in the system can only be cleared through the oil-gas separator, and the exhaust and oil replenishment are all completed in one pipeline, which takes a long time, sometimes as long as 2~ 3 hours, and the pressure of the circulating oil pump was unstable, air suction and vibration increased, which affected the normal production of the enterprise

[0004] The exhaust and oil replenishment of the heat conduction oil boiler pipeline system relies on one pipeline, and the operation is based on the experience of the boiler operator, which leads to a long exhaust time of the system, wastes a lot of energy consumption of the circulating oil pump, increases the risk of production safety, and Affect the normal production arrangement of the enterprise, and even lead to greater economic losses and safety accidents of the enterprise
