East C Variable Frequency Water Supply Equipment

Product Specification

Product Overview                     

• The BH - B variable - frequency water supply equipment (backpack type) adopts an integrated water - pump drive and control unit. The motor is an integrated motor with a frequency converter, which is an ultra - high - efficiency motor (IE5). It has low electromagnetic noise and high energy efficiency. Especially under low - load conditions, the driver and the motor are integrated as one unit with a high integration level, effectively addressing some pain points in current secondary water supply:
  • Low energy efficiency and high power consumption under non - full - load conditions. In civil buildings, water consumption is often in the medium and small flow range for a long time, and the used asynchronous motors operate at a low - efficiency state for extended periods.
  • Low digital integration of the equipment. The equipment uses a relatively large number of mechanical electrical components to control the water pump, resulting in weak compatibility, expandability, and usability.
  • High noise. Generally, the electromagnetic noise of the motor on the water pump is relatively large during variable - frequency operation, affecting surrounding residents.
  • Low integration level between the frequency converter and the motor. The two are separately installed, with complex wiring and poor versatility. Most manufacturers that integrate the frequency converter and the motor simply combine the frequency converter with the motor.
• The BH - BP variable - frequency water supply equipment (backpack type/new model) has the same functions as the BH - B equipment. It is an upgraded Plus version based on the BH - B in terms of appearance. The equipment is equipped with decorative enclosure panels for the pump group, which not only can prevent water splashing to a certain extent but also enhance the overall aesthetic appearance of the equipment.

Working Environment                    

• Power supply: 380V×(100±10%), three - phase five - wire system, with a frequency of 50Hz.
• Ambient temperature: 0°C to 45°C (Appropriate measures must be taken if it exceeds this range).
• Installation location: A place free of conductive dust, gases that can corrode metals and damage insulation, and explosion - free.
• Altitude: Not exceeding 1000m. When it exceeds, the control components and motors should be adjusted accordingly.

Scope of Application                    

• Secondary pressure - boosting water supply for buildings.
• Pressure - boosting water supply in urban and rural areas.
• Industrial water supply.
• Other places requiring secondary pressure - boosting.

Product Features                 

• Use of synchronous motors for high - efficiency energy - saving
  • With a precise motor thermal simulation platform and three - dimensional flow field analysis, it has an IE5 energy efficiency level, which is higher than that of asynchronous motors, achieving an energy - saving rate of over 5%.
  • The water supply equipment is in a low - load state 60% of the time. The synchronous drive integrated unit remains highly efficient under low - load conditions, such as when the occupancy rate of new residential buildings is low or during low - water - consumption periods, saving more than 20% energy in these situations.
  • It adopts full variable - frequency control. The optimal efficiency wheel value algorithm for parallel pumps ensures that a single pump in the secondary water supply system operates in a highly efficient state, enabling the system to save more than 15% energy.
  • The precise synchronous machine parameter model ensures that the output current is minimized when operating under the same load, reducing the copper loss of the motor and further saving energy.

Quiet Operation The electromagnetic noise of the motor is low at low frequencies, and the water pump runs smoothly. High Integration and High Stability The all - in - one unit features wide voltage and wide operating temperature design ranging from - 25°C to 50°C, with a protection level of IP55. The Printed Circuit Board Assembly (PCBA) of the frequency converter is coated with a thickened layer, which provides stronger protection against moisture, dust, and corrosion, thus extending the service life of the equipment. An integrated drive unit is adopted, with an integrated design for PLC, frequency converter, and motor (the frequency converter is not externally mounted). The control system and the equipment are delivered as a whole from the factory. No on - site wiring is required, which shortens the construction period.
