Product Usage
Residential water supply: Constant pressure water supply equipment is widely used in high-rise buildings, residential areas, villas and other places. In these occasions, constant pressure water supply equipment can ensure stable water pressure and meet the normal water needs of residents on each floor.
Commercial buildings and public places: hotels, office buildings, department stores, hospitals, schools, gymnasiums, airports and other public places also often use constant pressure water supply equipment. These places are densely populated and have large and concentrated water consumption. Constant pressure water supply equipment can provide a stable and clean water source to ensure the smooth daily water use.
Industrial production: In the production process of chemical industry, textile printing and dyeing industry, food industry, etc., constant pressure water supply equipment can provide stable water pressure to ensure the normal operation of production equipment and product quality. In addition, constant pressure water supply equipment is also suitable for production and manufacturing, washing equipment, factory areas and other scenes, meeting the strict requirements of industrial production on water quality and pressure.
Municipal construction: In municipal facilities such as city squares, parks, and public toilets, constant pressure water supply equipment can ensure stable and efficient water supply to meet the water needs of green irrigation and public facilities.
Product Operation Guide
1. Equipment installation First, you need to install the variable frequency constant pressure water supply equipment on a fixed water pump, and then connect it to the water source pipeline through a water pipe. When connecting, you need to pay attention to the connection method of the pipeline to ensure that the connection is smooth and there is no water leakage.
2. Equipment operation After connecting the equipment, you first need to turn on the power of the variable frequency constant pressure water supply equipment, and then open the water source valve to detect whether it is operating normally. If the equipment is operating normally, you should be able to hear the sound of the water pump working. During the operation of the equipment, the start and stop pressures can be set as needed. This can be set through the control panel of the equipment. After the equipment is started, a period of trial operation is required to check the operating status of the equipment and whether the pressure of the water pump is normal.
3. Setting operating parameters The variable frequency constant pressure water supply equipment can set operating parameters as needed. It can be set through the control panel of the equipment, such as setting the start time, stop time, etc. These parameters can be set as needed to better adapt to the water supply needs in different situations.
4. Prevent idling When the water source is interrupted or the water supply needs to be stopped, the water pump should be turned off in time to prevent damage caused by idling of the water pump.
5. Maintenance During use, attention should be paid to the maintenance of the equipment, such as regular replacement of filter elements, cleaning of equipment, inspection of electrical parts, etc. Specific operations can be performed according to the equipment manual to ensure the normal operation of the equipment and extend its service life.
Frequently asked questions
1. The system pressure is unstable and prone to oscillation. Adjust the location of the pressure sensor collection point to ensure that it is away from the water outlet of the water pump; check and adjust the pressure collection point of the air pressure tank; adjust the acceleration and deceleration time of the controller and inverter according to the water pump power.
2. The small pump starts and stops too frequently. Appropriately increase the value of the small pump stop pressure error in the controller parameters to reduce frequent starts and stops.
3. Analog output abnormality Check the analog output circuit of the controller and replace or repair it if necessary; adjust the frequency gain of the inverter to ensure that it matches the controller output.
4. The inverter output is not zero when the water pump is switched. Check and ensure that all control lines are firmly connected, especially the EMG signal line; use a multimeter to check whether the controller can output the EMG signal normally, and replace the controller if necessary.
