1、 Product Overview
QS-HBP（Q）The series of fully automatic variable frequency speed control water supply equipment is a water supply equipment that combines microcomputer technology, variable frequency technology, and motor control technology; It is an ideal product to replace high-level water tanks and towers. The device consists of a programmable controller, frequency converter, control circuit, and motor pump to form a closed-loop water supply control system, which can meet the requirement of maintaining constant pressure in the water supply system pipeline network. Keep the entire water supply system in an energy-efficient operating state.There are specialized water supply systems for daily use, dual-purpose water supply for daily firefighting, and variable frequency constant pressure water replenishment.

2、 Scope of application of variable frequency water supply equipment
1. Domestic water supplyIndustrial water requires constant pressure production water.
2. Fire water supply for high-rise buildings, residential areas, and military facilities.
3. The renovation of the existing water supply system (air pressure, water tower, high-level water tank).
4. Variable frequency constant pressure water replenishment system.

IIIVariable frequency water supply equipmentmain features
1. Adopting microcomputer control, fully automatic operation, simple management, convenient and reliable use.

2. Compact structure, small footprint, low investment, easy installation, and convenient centralized management.

3. Fully functional, various functions required by users can be achieved through panel operations.

4. Adjust the speed of the motor pump according to the required pressure and changes in water consumption, so that the equipment can supply water at a constant pressure and achieve energy-saving goals.

5. Reliable soft start can be achieved for multiple motor pumps, greatly extending the service life of the equipment.

6. Automatically complete the entire process of circulating soft start and stop for multiple water pumps based on changes in flow rate.

7. Equipped with a small pressure water tank device, the remote pressure gauge sends feedback to the controller, allowing the equipment to shut down at low or zero flow rates, further reducing energy consumption and extending the service life of the equipment.

8. Complete protection functions: undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, etc.

9. The working pump and standby pump have periodic operation, automatic inspection and manual inspection functions.
