Description

Technical Field

[0001] The utility model relates to the technical field of water supply devices, in particular to an intensive water supply device for cooling circulating water of a vacuum heat treatment production line. Background Art

[0002] The vacuum heat treatment production line is a high-end equipment, mainly used in the production of key parts of European and American aircraft, rail transportation, automobile industry engines, gearbox key parts, etc. The vacuum heat treatment production line belongs to the field of high-end equipment. The cooling circulating water system of the vacuum heat treatment production line plays a key role in ensuring the normal operation of the production line and extending the life of the equipment. Through reasonable system design and control requirements, the efficient and stable operation of the cooling circulating water system can be ensured, providing a strong guarantee for the production of the vacuum heat treatment production line. The vacuum heat treatment production line is usually composed of multiple furnaces, involving vacuum high-pressure gas quenching furnaces, vacuum tempering furnaces, vacuum nitriding furnaces, etc.

[0003] The vacuum high-pressure gas quenching furnace requires high-pressure and high-flow cooling water during the quenching and cooling stage to ensure the short-term water demand of the equipment (fast water supply pump). In other stages of the program operation, the cooling circulating water pressure of the vacuum high-pressure gas quenching furnace is low and the water flow is small (normal pressure water supply pump). The required normal pressure water supply pump needs to run all year round, and the fast water supply pump only runs during the quenching and cooling stage of the vacuum quenching furnace. Tempering furnaces, vacuum nitriding furnaces and other equipment also require long-term operation of cooling circulating water, and their flow rate and water pressure are relatively low. If each furnace is equipped with a cooling circulating water pump on a 1-to-1 basis, there will not only be a waste of equipment, but also a large footprint, a complex piping system, and great difficulty in control. Once the water pump fails, the corresponding heat treatment equipment will be at risk of shutdown. Utility Model Content

[0026] The effect achieved by the entire embodiment 1 is that, first, the cooling methods of the three furnace integrated bodies A10 respectively adopt low-pressure cooling circulating water of the vacuum quenching furnace, cooling circulating water of the tempering furnace, and cooling circulating water of the nitriding furnace, and two low-pressure water pumps 5 are used to complete the circulation treatment of the cooling liquid, and in this process, the control switch 8 can complete the start-up and closing replacement processing of the two electric valves 7.

[0028] The effect achieved by the entire embodiment 2 is that, first, the three furnace integrated bodies B17 are composed of two super-large vacuum quenching furnaces and one medium-sized vacuum quenching furnace, and the internal cooling method adopts three high-pressure water pumps 15 to supply large-flow, high-pressure cooling circulating water.

When the water pump needs maintenance or an abnormal failure occurs, the standby pump starts automatically.
