Overview and characteristics of deep well frequency conversion towerless water supply equipment I. Overview of Jiawei deep well frequency conversion towerless water supply equipment:
1. The core components of the deep well frequency conversion towerless water supply equipment are basically composed of world-renowned inverters such as ABB, Sancha, Delta, PID controllers, PIC programmable controllers, and other peripherals such as pressure sensors and water level controllers. Complete control system, deep well frequency conversion without tower water supply equipment The control system, together with the pump unit and management accessories, constitute a constant pressure variable frequency automatic water supply system.
2. When the deep well frequency conversion towerless water supply equipment control system works, the water pump controlled by the frequency converter starts softly at a low frequency and gradually accelerates. The pressure sensor installed on the water outlet pipe continuously monitors the pressure of the pipeline network and converts the pressure signal into electrical signal transmission. To the controller, the deep well frequency conversion towerless water supply equipment controller performs calculation and processing, and then transmits the command signal to the frequency converter. The deep well frequency conversion towerless water supply equipment makes the frequency conversion adjust the output frequency, thereby increasing the pump motor speed and changing the pump flow rate without the tower. The water supply equipment is made to meet the set pressure of the network and is kept constant. When the water consumption increases, the pump motor speed increases, and when the water is stopped, the pump motor is in a dormant state.
3, deep well frequency conversion tower-free water supply equipment in the control of multiple pump motors, if the speed of a single pump motor increases to the rated speed can not reach the set pressure value, the tower water supply equipment control system will automatically start the second pump, deep well If the frequency conversion tower-free water supply equipment still can not meet the set pressure value, the third and even more than one water pump will be automatically started and put into operation in turn. When the water consumption of the tower water supply equipment is reduced, the water pumps will exit the operation in the order of first stop and first stop. Until the set pressure value is reached.
Second, Jiawei deep well frequency conversion tower-free water supply equipment system advantages:
1. Replace traditional water supply devices such as water towers, high water tanks and pressure tanks. It occupies less land, saves investment, has shorter construction period and quicker effect, and can effectively prevent secondary pollution of water sources.
2. The soft start of the pump motor, no current and mechanical shock, effectively extend the service life of the motor and pump. It effectively eliminates the “return†loss of the constant speed water pump, avoids the “big horse trolley†phenomenon, improves the overall efficiency of the pump motor and comprehensive energy saving effect. Under normal circumstances, it can save 15%-48% and save 15% water. -30%.
3. Overcoming the overpressure water supply of the pipe network, effectively reducing the maintenance cost of the pipe network and reducing the operating cost.
4, diagnosis and self-diagnosis display, storage faults and alarms, digital human-machine interface, easy to operate.
Third, Jiawei deep well frequency conversion tower-free water supply equipment features:
1. Investment in the deep well frequency conversion tower-free water supply equipment: no need to build a water storage tank or water tank, nor need to set up a large pressure tank, saving a large investment, and because it can make full use of the water supply pressure of the water pipe network, the pressure pump selection The type can be reduced and the equipment investment is reduced.
2. Hygienic and non-polluting: the water supply system is completely sealed from the water pipe network to the user's faucet. Contaminants will not enter the system; the water body is not in direct contact with the air, and the overcurrent components are made of food grade stainless steel; no secondary pollution Opportunity, environmental sanitation.
3. Significant energy-saving effect: The deep-well frequency conversion tower-free water supply equipment is directly connected with the water pipe network, and the required pressure is superimposed on the basis of the pressure of the water supply pipe network of the waterworks, the difference is much, and the amount of compensation can be fully utilized. Pressure; water low peak, equipment does not even need to operate, energy saving effect is significant, compared with traditional water supply equipment, energy saving up to 30%-90%.
4. Water conservation: no regular cleaning, no waste of water resources and human resources, saving maintenance costs.
5. Small footprint: deep well frequency conversion tower-free water supply equipment does not need to build a water storage tank or water tank, does not need to be equipped with a large pressure tank, which greatly saves the system footprint, can make full use of the saved land to improve the utilization rate of the property, in line with the state The requirement to save land resources.
6. Low operating cost: Due to the small selection of the pressure pump and the multi-pump associated water supply, the city directly uses the water supply pressure of the city during the low peak period, and the equipment does not need to be pumped. Therefore, the deep well frequency conversion has no tower water supply. The energy consumption during the operation of the equipment is very low, which reduces the running cost.
7. Water supply will not stop when the water supply is insufficient: At present, most of the pipe network overlap (no negative pressure) in the market will be shut down due to lack of water supply when the city's water supply is insufficient, so it is often at the peak of water consumption. The pump starts or stops frequently, or it simply stops, which seriously affects the normal continuous water supply.
8. Easy to install: When the equipment arrives at the site, it only needs to be connected to the water inlet and outlet pipes. The construction period is short and the installation is simple.
9. Power failure will not stop water supply: For deep well frequency conversion, there is a public water supply pipeline that communicates directly with the user pipe network. In the event of power failure, the pressure pump stops working, but the water supply pressure of the water supply plant can maintain the water supply.
10. Easy management and maintenance: The deep well frequency conversion towerless water supply equipment is fully automatic control of the frequency conversion speed control of the microcomputer. The power failure equipment is automatically stopped, the incoming call is automatically turned on, and the complete fault detection, diagnosis technology and alarm reminding make the equipment management and maintenance extremely simple. Since there is no pollution, there is no need for troublesome cleaning work.
