Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 As shown, the embodiment of the present invention provides a sealed cooling system of a hot water circulation pump, which includes: a cooling chamber, a soft water tank 1 , a first pipeline booster pump 2 and a first driving device 4 .
[0026] The cooling chamber is the structure of the hot water circulation pump 3 itself. This embodiment does not change the structure of the cooling chamber. The structure of the cooling chamber can be referred to: the invention name is a high-temperature and high-pressure hot water circulation pump, and the patent number is ZL200610050133.9 For the cooling chamber disclosed in the literature, reference may also be made to other literature, which is not limited in this embodiment. The cooling medium in the cooling chamber enters from the cooling water inlet 31 of the cooling c...

The invention provides a sealed cooling system of a hot water circulating pump. The cooling system comprises a cooling chamber, cooling media enter from a cooling water inlet of the cooling chamber so as to cool a seal, after the seal is cooled, the seal is discharged from a cooling water outlet of the cooling chamber, and the cooling system further comprises a soft water box, a first pipeline booster pump and a first drive device; the soft water box is used for providing softened water, and the cooling media are softened water; the first pipeline booster pump is used for providing drive force for flowing of the softened water in the cooling chamber, a water inlet of the first pipeline booster pump is communicated with a softened water tank, and a water outlet of the first pipeline booster pump is communicated with a cooling water inlet; the first drive device is used for driving the first pipeline booster pump to work; and the hot water circulating pump is used for conveying the softened water entering from a suction opening of the hot water circulating pump. The invention further provides a heating furnace water beam stand column cooling mechanism. The service life of the hot water circulating pump is prolonged.
Description
technical field [0001] The invention belongs to the technical field of continuous casting in metallurgical production, and in particular relates to a sealed cooling system of a hot water circulation pump and a cooling mechanism for a water beam column of a heating furnace. Background technique [0002] In the metallurgical industry, such as the water beam column of the heating furnace, etc., the vaporization cooling method is often used to maintain the normal working temperature of the stressed structural parts. The reason why the vaporization cooling technology is adopted mainly considers the following aspects: one is to save water resources, the use of vaporization cooling technology can save at least half of the water consumption than the normal temperature water cooling technology; the other is that there can be high temperature and high pressure steam, It is convenient for subsequent waste heat recovery, such as for power generation, heating, preheating, etc., to improv...
