MZBW type self-priming life frequency conversion water supply equipment
MZBW type self-priming life frequency conversion water supply equipment has strong energy storage and pressure holding capacity, especially when dealing with a small amount of water at night, which can greatly save electricity.
Overview:
MZBW type self-priming life frequency conversion water supply equipment. Economic, sanitary and energy-saving effects are remarkable. Practice has proved that the use of intelligent non-negative pressure frequency conversion water supply equipment can save more than 50% of the cost of building a pool. Compared with other water supply equipment, it can save electricity by 20%-50%;
Easy to install and save floor space. "Anti-corrosion treatment" is used on the inner wall of the tank;
It can be used for any domestic and industrial water, and can also be used for central air-conditioning system, water plant pressurization, farmland irrigation, sewage treatment, artificial fountain, fire-fighting water, and can be equipped with any type of water pump. If users have special requirements, they can be customized through negotiation;
It adopts frequency conversion control technology, has soft start, and has functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overheating and stall protection. Carry out signal alarm, self-check, fault judgment, etc. under abnormal conditions, and automatically adjust the water supply flow according to the level of water consumption;
Features of MZBW self-priming life frequency conversion water supply equipment:
1. The self-priming variable frequency speed regulating water supply equipment has strong energy storage and pressure holding capacity, especially when dealing with a small amount of water at night, which can greatly save electricity.
2. Adjust the volume (the amount of water available to the user every time the pump is started) is large. Each time the pump is started, the pipe network pressure can be maintained for a long time, the number of equipment starts is small, and the operating cost is low.
3. The self-priming frequency conversion speed regulating water supply equipment adopts air supplement technology. The air supply of the air pressure tank adopts microcomputer electronic detection, limited air supply and exhaust technology to ensure that the gas in the tank has a certain volume at any time, which fundamentally solves the problem of frequent pump startup caused by long-term gas failure.
4. According to the site conditions of different users of self-priming variable frequency speed regulating water supply equipment, the automatic water feeder without tower can adopt the following different configurations.
Principle of frequency conversion control of self-priming frequency conversion speed regulation water supply equipment:
Using variable frequency speed regulation to achieve constant pressure water supply, compared with the use of regulating valves to achieve constant pressure water supply, the energy-saving effect is very significant (can be calculated according to the specific situation). The advantages are:
1. The starting is balanced, the starting current can be limited within the rated current, thus avoiding the impact on the power grid during starting;
2. As the average speed of the pump is reduced, the service life of pumps and valves can be prolonged;
3. It can eliminate the water hammer effect when starting and stopping;
Generally speaking, when a motor is controlled by a frequency converter, it is only necessary to make the capacity of the motor equipped with the frequency converter match the actual motor capacity. When a frequency converter controls two motors at the same time, in principle, the capacity of the motor equipped with the frequency converter should be equal to the sum of the capacities of the two motors. However, if the water consumption at peak load is much different than the full-speed water supply of the two pumps, consider appropriately reducing the capacity of the inverter, but pay attention to leaving enough capacity.
Advantages of water supply equipment:
1. Power saving: Optimized energy-saving control software enables the water pump to achieve maximum energy-saving operation;
2. Water saving: Set the pressure of the pipe network according to the actual water consumption, automatically control the water output of the water pump, and reduce the phenomenon of water running and leakage;
3. Reliable operation: the soft start of the pump is realized by the frequency converter, so that the water pump can realize the impact-free switching from the power frequency to the frequency conversion, to prevent the impact of the pipe network, and avoid the pressure of the pipe network from exceeding the limit and the pipe rupture.
4. Networking function: using all Chinese industrial control configuration software, real-time monitoring of various sites, such as motor voltage, current, working frequency, pipe network pressure and flow, etc.
5. Flexible control: segmented water supply, timed water supply, manual work mode selection.
6. Perfect self-protection function: If a pump fails, it will actively send out an alarm message to the upper computer and start the standby pump at the same time to maintain the water supply balance. In case of failure of the automatic control system, the user can directly operate the manual system to maintain normal water supply.
