The water supply project of Huaneng Resort Ski Resort in Changbai Mountain, Jilin Province uses PERFECT industry vertical multi-stage long axis semi submersible deep well turbine pump as a high lift

The water supply project of Jilin Changbai Mountain Huaneng Resort Ski Resort uses HUNAN PERFECT industry vertical multi-stage long axis semi submersible deep well turbine pump, which is a high lift core water supply equipment customized for the special working conditions of Changbai Mountain's high altitude, large altitude difference, and extremely cold and low temperature. It is specifically designed to provide stable high-pressure water sources for the ski resort's snowmaking system and high-altitude living water supply in the holiday village.
Core operating condition characteristics
High head precise matching: In response to the hundreds of meters of height difference between the water intake point at the foot of Changbai Mountain Ski Resort and the snow trail at the top of the mountain, the vertical multi-stage long axis semi submersible deep well turbine pump achieves a super high head of 360m through multi-stage impeller series connection, without the need for multi-stage booster pump stations, greatly simplifying the water supply system architecture and reducing overall energy consumption.
Customization for extremely cold environments: Suitable for extreme low temperatures below -30 ℃ in winter in Changbai Mountain. The pump body flow components are made of low-temperature resistant ductile iron+304 stainless steel material, and are equipped with a full pipeline insulation and protection structure to avoid low-temperature freezing damage and ensure 24-hour continuous and stable operation during the winter snow making peak period.
Adaptation of water intake in scenic spots: The vertical long axis structure can directly immerse the pump body into the water intake of Changbai Mountain streams or deep wells, without the need for additional vacuum water intake devices, with high start-up efficiency, and is suitable for the limited installation space of remote water intake points in scenic spots.
Core parameters of the project
Conventional customization parameters: flow coverage of 150-250m ³/h, head of 280-400m, matching motor power of 280-400kW, speed of 1450r/min, operating efficiency of over 78%, fully meeting the daily snow making water supply demand of thousands of cubic meters for ski resorts.
Structural design: Adopting a 12-16 stage impeller series boosting structure, the long axis can be customized to a length of 1-10m according to the actual underwater depth of the water intake point. The guide bearing is made of imported Sailong wear-resistant material, and no external lubricating water is required when transporting clean water, making maintenance convenient.
Intelligent configuration: Equipped with a remote variable frequency control cabinet, it realizes automatic start stop of liquid level, overload alarm, remote monitoring of operating status, and adapts to the needs of unmanned water supply stations scattered in ski resorts.
