Vertical Multi-Stage Fire Pump
- 产品描述
-
I. Product Overview
Kechu Group's vertical multi-stage fire pump is designed based on a multi-stage centrifugal pump structure, which achieves step-by-step pressure increase through the series connection of multi-stage impellers, and can provide high head output in a compact structure. This product is optimized for the water supply needs of high-rise and super high-rise building fire protection systems, ensuring fast start-up and continuous pressure supply while achieving efficient and stable operation. As a key power equipment in the fire protection system, it not only undertakes the task of water supply, but also serves as an important foundation for ensuring the reliable operation of high-pressure fire protection systems.
II. Application scenarios
● Fire water supply system for high-rise and super high-rise buildings
● Large commercial complexes and urban complexes
● Industrial high-rise buildings and storage facilities
● Underground space and long-distance transportation fire protection system
● High pressure fire protection pipeline network and partitioned water supply system
III. Working principle
The motor drives the pump shaft to rotate, driving multi-stage impellers to transfer energy to the liquid step by step. The liquid obtains kinetic energy in each stage of the impeller and converts it into pressure energy, which is then stacked in multiple stages to form a high-pressure output. This continuous pressurization mechanism enables the equipment to achieve high head in a small volume while maintaining stable flow output, meeting the operational requirements of high-pressure fire protection systems.
IV. System composition
● Stainless steel/copper multi-stage impeller component (gradually pressurized core)
● Diversion shell and expansion structure
● Stainless steel pump shaft and bearing system
● Sealing system (mechanical seal or packing seal)
● Motor drive system
● Import and export connection structure
V. Core Technology
● Multi stage pressurized hydraulic design technology
● High head stable output control technology
● High reliability structure and durability design
● Low vibration and balanced operation technology
● Linkage and adaptation technology with fire control system
VI. Performance characteristics and product advantages
