Refrigeration temperature control type goods shelf

Номер: CN0211823443U

The utility model relates to a refrigeration temperature control type goods shelf. The goods shelf comprises stand columns, middle supports and top layer supports, the stand columns, the middle supports and the top layer supports form a goods shelf body, the stand columns, the middle supports and the top layer supports adopt hollow interlayer structures as air supply channels, small holes are formed in the lower surface of each supporting layer, a goods shelf internal pore plate air supply structure layer is formed, and jet holes are formed in the outer side of the plate air supply structure layer; a draught fan, a refrigerating coil and a valve plate assembly are arranged in the bottommost space of the goods shelf body. A refrigerant is introduced into the valve plate assembly to be throttled into a low-temperature and low-pressure gas-liquid two-phase state; then the air enters a refrigerating coil to be evaporated; return air in the goods shelf is cooled after passing through the refrigerating ...

Integrated vibration reduction rack for marine water chilling unit

Номер: CN116215827A
Принадлежит:

The invention relates to an integrated vibration reduction rack for a marine water chilling unit, which comprises an electric cabinet, a condenser, an integrated rack, a plate-type evaporator and a compressor, the condenser is welded with a vertical plate to form the integrated rack, and the electric cabinet, the plate-type evaporator and the compressor are connected onto the integrated rack to form an integral structure. The vibration frequency of the compressor is firstly transmitted to the condenser body and then transmitted to the unit legs through the integrated rack, so that the effect of vibration isolation for multiple times is achieved. By the adoption of the integrated structure, the whole connecting rigidity of the unit is fully enhanced while all parts of the unit are connected, and the unit rack not only serves as a unit connecting piece, but also can improve the vibration frequency of the unit during operation. The unit size is reduced while the vibration frequency of the ...

Tube inner wall land pre-film-forming treatment process of heat transfer tube

Номер: CN116043202A
Принадлежит:

The invention discloses an onshore pre-film-forming treatment process for the inner wall of a heat transfer tube. The onshore pre-film-forming treatment process comprises the following steps: enabling the heat transfer tubes to penetrate into a tube plate or the tube plate and a supporting plate one by one; sealing rings sleeve the ends of the heat transfer tubes as required, and after all the heat transfer tubes are installed, pressing plates are screwed on the tube plates to tightly press the two ends of the heat transfer tubes; the end cover is covered and tightened, and the water leakage phenomenon should be avoided through water utility inspection; and continuously running for 240 hours by introducing water, and controlling the running flow rate to be 1-1.6 m/s. According to the technology, land water containing oxygen at a certain flow rate is used for conducting film pre-forming treatment on the inner wall of the heat transfer pipe, a passive film is formed on the inner wall of the ...
