Stainless steel water tank
System pressure can be set as required and the system can automatically adjust water pump speed and the number of water pumps in operation, thus ensuring high energy efficiency.
2. Stable supply water pressure
The system can realize closed-loop control and automatically adjust the difference between system pressure and pressure setting, thus ensuring constant system pressure.
3. Simple operation
Automatically controlled by the frequency converter or both the converter and the PLC program, it is easy to operate.
4. Complete protection
It has short circuit, overcurrent, overvoltage, overheat, overload and multiple other protective mechanisms and automatically stops and gives an alarm when the water pump fails. The system is featured with such functions as self-inspection, fault diagnosis, fault memory, fault display, automatic start of standby pump, etc.
5. Extended motor and water pump life
Since all pumps adopt soft start, surge current during startup is eliminated, thus extending service life of the equipment. Besides, soft start of the pumps is conducted cyclically, so none will get corroded due to long-term disuse or worn due to frequent use.
6. Automatic operation of attached low-flow pump
A small pump may be attached to it, so that the system can automatically shut down the main pump during night or in the case of low flow and start the attached small pump, thereby avoiding waste of electric energy by the high-power pump.
7. Variable frequency adjustment effectively avoids the phenomenon of “water hammer”.
8. Programming and setting of the frequency converter and the controller are simple and easy to master.
9. It is fitted with a manual control switch to ensure safe and continuous operation of the equipment.
10. The communication can be connected to a computer, thereby realizing direct control through the computer network.
