Overview

The ALBK series variable frequency constant pressure water supply automatic control cabinet uses AC variable frequency speed regulation technology and microcomputer detection and control technology. It is composed of a variable frequency speed regulation, a programmable controller or an intelligent alternating frequency speed regulation constant pressure water supply controller, and the introduction of low-voltage electrical appliances. It is a new type of water pump with full flow range positioning

Product Details

产品介绍

The control cabinet uses the instantaneous pressure changes in the system pipeline network as a stable parameter(Comparative positioning) Control the output frequency of the frequency converter through a microcomputer. Automatically track and adjust the speed of the water pump; Realize PID closed-loop regulation of system water pressure to ensure constant pressure at the end of the pipeline network, enabling the entire water supply system to operate continuously and efficiently.

.Choose internationally renowned frequency converters, programmable controllers, and low-voltage electrical appliances:
Digital PID regulation, keyboard operation, numerical display, fully automatic operation without human supervision:
The circuit design is clean and clear, with clear thinking, making it easy to analyze and repair faults

Excellent performance, flexible control mode, strong anti-interference ability, stable and reliable operation;
Non loss regulation of water pump motor speed: achieving stepless variation of water supply from zero to the maximum value of the system;
In automatic mode, the water pump motor achieves soft start. No impact on the power grid and pipeline network, greatly extending the service life of water pumps, motors, pipeline systems, and electrical control systems;

Manual and automatic control function settings can ensure the safe and continuous operation of the equipment;
Programmable control, capable of implementing multiple control methods according to user requirements.
Multiple pumps can operate alternately and cyclically, balancing the average working time of each pump and extending the service life of the water pump

The basic control function is powerful, and there are abundant additional functions to choose from. asTimed switch system, automatic switching of water pump operation. Automatic shutdown, sleep connection, remote control, on-site control, etc. for low and zero flow water usage.

Timed start and stop of pumps: capable of programming and controlling the operation status of equipment on and off in units of hours, days, weeks, etc;

Regular rotationCan program and control the rotation interval of the water pump in units of hours, days, weeks, etc.

Main protections: overload, short circuit, phase loss, automatic protection for water source interruption, grounding protection, overpressure protection, water flooding pump room protection, system burst protection, etc. of the water pump motor;

Single pump power≤ 22KW manual power frequency direct start; Single pump power ≥ 30KW manual power frequency star delta or autotransformer voltage reduction start.

1. Automatic addition and subtraction of pumps: The equipment can automatically increase or decrease the number of running pumps according to the user's water demand;
2. Basic pump, auxiliary pump, automatic rotation operation; The basic pump and auxiliary pump can switch their working sequence during the next start-up of the equipment, which can evenly distribute the running time of each pump;
3. Variable frequency pump cycle operation: When adding a pump, the first pump starts with variable frequency. When switching to the power frequency state for operation, the other pump also runs with variable frequency, and so on. When reducing the pump, the first pump to switch should be turned off first. According to the principle of starting first and stopping first;
4. Mutual backup pumps: Backup pumps can also participate in alternating rotation operation;
5. The backup pump can be automatically put into operation in case of a malfunction: if a pump fails, the backup pump can take over the operation.
