Embodiment 1

[0034] As shown in the accompanying drawings of the description, an efficient split-type diesel engine cluster cooling system includes a water cooling system 1, an oil cooling system 2, a single air-cooled supercharged diesel engine 18 and a control system; the water cooling system 1 mainly includes a water treatment unit 4 and chilled water unit 13; the inlet of the water treatment unit 4 is connected to a raw water pipeline 5, and the outlet is connected to a pure water outlet pipeline 10; the pure water outlet pipeline 10 is divided into a pure water branch pipe I9 and a pure water branch pipe II11; The pure water outlet pipeline 10 is connected to the ice water unit 13; the outlet of the ice water unit 13 is connected with the ice water outlet pipeline 15, and the water return port is connected with the ice water return pipeline 14; the ice water outlet pipeline 15 separates the ice Water branch pipe 16; the end of the pure water branch pipe II11 connected to the ice water ...

Embodiment 2

[0043] The structure and principle of this embodiment 2 are basically the same as that of embodiment 1, the difference is that the entrance of the heat dissipation box 28 is located on the upper part of the box wall, and is provided with a fuel injection port 29 with a "V" opening; the fuel injection port 29 is connected to Oil return pipe 24. High-temperature machine oil flows into the cooling box 28 from the single-air-cooled supercharged diesel engine 18, and is sprayed out through the fuel injection port 29, and the fuel injection port 29 of the "V" word opening plays the effect of expanding spraying.

Embodiment 3

[0045] The structure and principle of this embodiment 3 are basically the same as that of the embodiment 1, except that the two sides of the bottom of the cooling box 28 are respectively connected with a bottom oil outlet pipe 31 and an oil passage pipe 45 at the bottom of the case; the oil passage pipe 45 is provided with a proportional valve XXIX45 -1. When cleaning or maintenance is required, the oil pipe 45 is used to discharge the engine oil in the cooling box 28 .

Abstract

The invention provides an efficient split type diesel engine clustered cooling system and an application method thereof. A water cooling system, an oil cooling system, a single-air-cooling pressurizing diesel engine and a control system are included. The water cooling system comprises a water treatment unit and an ice water unit. The water treatment unit and the ice water unit are connected with the single-air-cooling pressurizing diesel engine through pipelines. The oil cooling system is provided with a heat exchange unit. A heat dissipation box, a cold water plate heat exchanger and an ice water plate heat exchanger are arranged in the heat exchange unit. An exhaust cover and an exhaust channel are arranged on the top of the heat dissipation box. The water treatment unit and the ice water unit are connected with the cold water plate heat exchanger and the ice water plate heat exchanger through pipelines. The single-air-cooling pressurizing diesel engine is connected with the interiors of the cold water plate heat exchanger and the ice water plate heat exchanger through oil pipes. The heat exchange unit is further provided with at least one standby heat exchange unit. According tothe efficient split type diesel engine clustered cooling system and the application method thereof, high efficiency and flexibility are achieved, function zone division is clear, arranging and overhauling are convenient, and work clustered usage of the large pressurizing diesel engine can be achieved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a high-efficiency split-type diesel engine cluster cooling system and its application method. Background technique [0002] When the diesel engine is working, it will generate a lot of heat, which will cause the parts to be heated strongly. If there is no proper cooling, the normal operation of the diesel engine body cannot be guaranteed. Existing diesel engines generally adopt an integrated water-cooling mechanism, but in large-scale supercharged diesel engines that generate higher heat, traditional water-cooling alone requires a huge water-cooling component, which brings great inconvenience to installation, use and maintenance; At the same time, with the development of modern industry, the independent operation of a traditional single diesel engine can no longer meet the production needs of modern factories. The production cluster composed of multiple sets of diesel...
