Copper alloy mouse cage ventilated motor island reef fresh water union manufacturing machine

Abstract

The invention belongs to a special machine for obtaining fresh water from sea, and relates to a copper alloy mouse cage ventilated motor island reef fresh water union manufacturing machine. A pressure-increasing union joint, a pressure-relieving union joint, a low-pressure union joint and a pressure-storing union joint are arranged on a union pressure exchange lifting machine pump. As an improvement, a horizontal union constant-direction flowing device is connected in series between the inlet of a low-pressure lifting pump and a low-pressure suction pipe; a vertical constant-direction flowing device is connected in series between the inlet of a high-pressure supplementing pump and a water-supplementing suction pipe; the union pressure exchange lifting machine pump consists of a pressure lifting union pump part and a union pressure exchanger part; a pressure lifting union pump is driven by a mouse cage water-cooled ventilated motor; by adoption of union connecting structures, assembling, disassembling and maintenance are facilitated, in particular, a flange pressure exchange lifting machine pump is additionally provided, a boosting pump suction port in a pressure lifting flange part directly aligns with a boosting central row hole in a union pressure exchanger part, so that the structure is compact and a significant energy-saving effect is achieved; and a cooling interlayer is arranged between the outer wall and the inner wall of a motor shell, so that the cooling effect is improved.

Description

technical field [0001] The invention belongs to a special machine for obtaining fresh water from the sea, in particular to a fresh water union manufacturing machine for a copper alloy squirrel cage air-cooled motor with a pressure exchange hoist pump added in a reverse osmosis seawater desalination system. Background technique [0002] With the advancement of science and technology, the population is increasing day by day, and people's desire to develop into the ocean is becoming stronger and stronger. Seawater desalination treatment is becoming more and more popular, and the energy consumption cost of seawater desalination has received special attention. Early seawater desalination used distillation, such as multi-stage flash technology, with an energy consumption of 9.0kWh / m3, and was usually only built in areas with low energy prices, such as Middle East oil countries, or areas where waste heat was available. In the 1970s, reverse osmosis seawater desalination technology ...

Problems solved by technology

[0006] 3. The earliest and most successful developed countries that invested in seawater desalination, such as Japan, Denmark, Netherlands, Sweden, Norway, the United Kingdom, the United States, and Germany, have all made efforts in pressure exchange, but their highest exchange efficiency has not exceeded 95 %, and the supporting project is huge, too many control components such as external electrical drive and switching valves lead to frequent accidents, which eventually lead to a substantial increase in equipment investment and additional costs such as daily management and maintenance
