Description

Technical Field

[0001] The utility model relates to an integrated fire-resistant oil station. Background Art

[0020] Reference Figure 1 An integrated fire-resistant oil station comprises: an oil tank 1, the oil outlet of the oil tank being connected to a forced cooling circulation pipeline 2, a main circulation pipeline 18, and a backup circulation pipeline 12. The forced circulation pipeline is divided into two routes, one being a forced circulation return oil pipe 4 and the other being a forced cooling pipe 5. The forced circulation return oil pipe is connected to the oil return port of the oil tank, the forced cooling pipe is connected to a cooler 17, and the oil outlet of the cooler is connected to the oil return port of the oil tank via a pipeline.

[0021] The main circulation pipeline and the backup circulation pipeline are combined into a total circulation oil return pipe 8 connected to the oil return port of the oil tank;

[0022] The total circulation oil return pipe is connected to two branches, one of which is the energy storage oil inlet pipe 15, which is connected to the accumulator 9, and the outlet of the accumulator is connected to the oil return port of the fuel tank through the energy storage oil outlet pipe 7;

[0023] The other branch is an oil outlet pipe, which is connected to the oil cylinder and the emergency trip module 16.

[0024] In the integrated fire-resistant fuel station, a circulation motor pump 3 is installed on the forced circulation pipeline.

[0025] In the integrated fire-resistant fuel station, a main motor pump 11 is installed on the main circulation pipeline.

[0026] In the integrated fire-resistant fuel station, a backup motor pump 10 is installed on the backup circulation pipeline.

[0027] In the integrated fire-resistant fuel station, a high-pressure filter 21 and a pressure difference alarm 22 are installed on both the main circulation pipeline and the backup circulation pipeline.

[0028] In the integrated fire-resistant oil station, the forced cooling circulation pipeline, the main circulation pipeline and the standby circulation pipeline are respectively installed with oil pressure gauges 23 .

[0029] There are three circulation lines connected to the oil tank outlet: a forced cooling circulation line, a main circulation line, and a backup circulation line. The oil tank outlets of the three circulation lines are all equipped with oil suction filters to effectively filter the oil out of the tank. The oil out of the tank is circulated to the cooler through the forced cooling circulation line, and then returns to the tank to cool the hydraulic oil after heat exchange with cooling water in the cooler.

[0030] A main motor pump is set on the main circulation pipeline, and a backup motor pump is set on the backup circulation pipeline. High-pressure filters and pressure difference alarms are set at the motor pump outlets corresponding to the main circulation pipeline and the backup circulation pipeline. Alarms will be issued in case of blockage, and the hydraulic oil will be filtered again. The main circulation pipeline and the backup circulation pipeline are combined into a total circulation pipeline. The total circulation pipeline will be divided into three routes. The first route will enter the accumulator for energy storage and return to the oil tank after energy storage. The second route will directly return to the oil tank. The third route will supply the oil cylinder and the emergency isolation module. After returning the oil, it will be cooled by heat exchange through the second cooler and return to the oil tank after cooling.
