Advantages of secondary water supply equipment:

1. No need to build a water tank, energy-saving, and cost saving:

The secondary water supply equipment is economical, hygienic, and has significant energy-saving effects. Practice has proven that the use of intelligent non negative pressure steady flow water supply equipment can save more than 50% of the cost of building new water tanks. Compared with other water supply equipment, it can save 20% to 40%.

2. Easy installation and space saving:

The secondary water supply equipment can be equipped with both horizontal and vertical steady flow tanks. The two types of steady flow tanks have different characteristics: horizontal steady flow tanks occupy less space, while vertical steady flow tanks occupy less area. The manufacturing and testing of steady flow tanks comply with the provisions of GB150 "Steel Pressure Vessels", and the inner walls of the tanks are coated with advanced "841 epoxy polyamide food container inner wall coating" for corrosion prevention, ensuring safety and compliance with national food hygiene standards.

3. Widely applicable and adaptable:

The secondary water supply equipment can be used for domestic water supply, fire water supply, and can be equipped with any type of water pump. When the equipment is used for fire protection, it is recommended to equip it with a dedicated fire pump.

4. Fully functional and highly intelligent:

The secondary water supply equipment adopts advanced human-machine frequency conversion control technology, with soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating, and stall protection functions. Signal alarm, self check, fault diagnosis, etc. are carried out in abnormal situations, and the water supply flow rate is automatically adjusted according to the high or low water consumption.

5. Advanced products and reliable quality:

The accessories used in the secondary water supply equipment have been selected by many manufacturers and have reliable quality assurance. The key components in the product, such as motors, water pump bearings, frequency converters, circuit breakers, contactors, relays, etc., are made of international and domestic high-quality branded products.

Working principle of secondary water supply equipment:

Secondary water supply equipment, usually located on the ground or in the basement. With a water supply unit, it is possible to schedule the peak water usage of this equipment, increase water pressure, and meet the demand for large-scale and high-altitude water supply during peak water usage. There are no factories, factories, or villages with water supply equipment. Simply connect this equipment to the water source power supply to obtain stable water pressure and meet water demand. The secondary water supply equipment consists of a control system consisting of gas tanks, water pumps, and electrical devices. It does not require the establishment of a water tower, has the advantages of low investment, small footprint, flexible organization, completion, and rapid production. Automatic water and gas distribution, automatic operation, energy-saving, automatic connection between tap water and power grid, water supply can still be provided after power outage, and no need for supervision after debugging. Widely used for enterprise production, daily and operational water supply, vertical residential areas, and villages without towers. Suitable for places with a daily water supply of less than 3000m3 and a water supply height greater than 100 meters.

The secondary water supply equipment adopts pneumatic water supply, using a closed water tank to achieve the purpose of water supply by utilizing the high-pressure gas and water pressure in the tank. The specific operation of the second time is to use a water pump to reverse the water and enter the valve pressure in the tank, compressing the gas in the tank and gradually increasing the pressure. When the pressure reaches the specified upper limit, the electric contact pressure gauge automatically connects the pump through the control cabinet. The water pressure in the equipment is such that when the water level in the water tank decreases and the gas expansion pressure in the variable frequency constant pressure supply water tank drops to a specified lower value, the water will be higher than the pressure in the external pipeline network and automatically sent to the water supply pipeline network. At the limit, the electric contact pressure gauge restarts the water pump through the control cabinet. This repetition keeps the device supplied with water r. When the gas in the tank is insufficient, the inflation valve can automatically fill with air.

Maintenance and upkeep of secondary water supply equipment

1. Please carefully check the power input line and motor (output) line of the frequency converter before trial operation, otherwise it may damage the frequency converter. The grounding terminal of the frequency converter should be effectively grounded. It is strictly prohibited to connect advanced compensation capacitors and surge absorption circuits that improve power factor to the output end of the frequency converter.

2. It must be used under environmental conditions. The service life of the frequency converter of the secondary water supply equipment is greatly affected by the temperature, humidity, ventilation, vibration, dust, etc. of the installation site. Therefore, reducing the ambient temperature during use is one of the important factors to extend the service life.

After cutting off the current, the high-voltage capacitor inside the frequency converter of the secondary water supply equipment still accumulates charge for a period of time. When conducting maintenance, please wait for the red light-emitting tube indicating discharge to turn off before proceeding.

When the frequency converter malfunctions, the five alarm contents memorized in chronological order can be read from the corresponding parameter window of the frequency converter of the secondary water supply equipment. Based on the alarm code and the instructions in the manual, analyze the cause of the fault and take measures to eliminate it.

When there is an instant power outage or insufficient power supply voltage, the frequency converter of the secondary water supply equipment will stop working. At this time, the circuit breaker can be disconnected to release the frequency converter alarm. After the power supply voltage returns to normal, the circuit breaker can be closed again, and the frequency converter can resume working.

When the frequency converter or motor of the secondary water supply equipment malfunctions, it will emit an audible and visual alarm. Pressing the alarm release or alarm mute button can release the sound, but the device is still in the alarm state.

7. The system of the secondary water supply equipment is fully automatic control, and there is no need for a dedicated person to be on duty during daily operation. However, regular checks should be conducted on the instruments and indicators in the electrical control cabinet to ensure that they are normal, the motor current and output frequency values are normal, and the operation of the motor. Any abnormalities found should be dealt with in a timely manner.

8. After the overall system is debugged under our guidance, it is best for users not to modify the parameters that have been adjusted themselves during use. If there is a malfunction or parameter modification required, it must be carried out by professional personnel who have been trained by us, are familiar with this operating procedure and precautions, and are certified to work, or directly notify us.

The above is the detailed information about the equipment compiled by the manufacturer of Zhengyuan Environmental Protection's secondary water supply equipment. If there are still unclear areas, you can consult our engineers and customize the equipment that suits your actual situation. Whether the secondary water supply facilities are constructed, designed, and installed in accordance with regulations directly affects the quality, pressure, and safety of the secondary water supply, and is closely related to the normal and stable life of the people.
