Detailed Product Description: | Xinyang water tower equipment, Walter da Meng Meng meaning of life, Xinyang water tower equipment manufacturers, the changes do not care about the outside world, and it is the quality of care. Walter -------- ------------------------- For more information, please contact Walter Hunan Water Equipment Co., Ltd. Address: Changsha High-tech Lu Tin Road Development Zone on the 8th floor Oak Park 5 Meng Meng Da -------------------- ------------ Xinyang No part of the water tower equipment: 1, modular stainless steel water tank (with pump house). 2, intelligent electrical control system. 3, low noise stainless steel multi-stage centrifugal pump. 4, no negative pressure water equipment and anti-backflow device. 5, stainless steel tubing sets. 6, pressure, liquid level signal acquisition, feedback facility. Xinyang water tower equipment work process: when a pipe network pressure is higher than or equal to user pressure when the water pressure is higher than the user pressure, the bypass valve is turned on, the water is supplied directly by the water users. Users pressure is higher than or equal to the set pressure, frequency conversion equipment is not running, the pump is shutdown. 2, the pipe network pressure is lower than the frequency conversion device when the user starts running the pressure pump is operational. A, pipeline flow is greater than equal to water users within the air flow regulator has if the pressure increases, and excess gas flow regulator can be discharged outside. Fills the inner water flow regulator to prepare for the next peak water use periods. When the water fills the flow regulator, vacuum suppressors installed in the top of the flow regulator automatically shut down to prevent overflow. Flow regulator pressure to return to the water pipe network pressure. If there is no air flow regulator, flow regulator pressure to maintain water pressure in the pipe. Pump upgrade for users of water pressure and differential pressure of the pipe network pressure. That pump provides users of water pressure head = - pressure pipe network B, network traffic is less than water users to reduce traffic pressure regulator, flow regulator when the pressure is lower than an atmospheric pressure mounted on top of the negative pressure flow regulator suppression automatically opens allowing gas into the flow regulator, eliminate the negative pressure. The pressure drop to zero within the flow regulator. Water flowing together to provide flow regulator inside the tap water and to water users. Reserve water flow regulator compensation is the difference between user and network flow of water. Pressure pump upgrade for users of water pressure. Quality Inspection Xinyang pump without water tower equipment: In general, when the device by a frequency control a motor, just so you can use the drive with a motor capacity in line with the actual motor capacity, when one inverter simultaneously control two motors, in principle, with the drive motor capacity should be equal to the capacity of the two electric motors and. However, if at the time of peak load of water supply quantity than two pumps at full speed a lot of difference. May be considered appropriate to reduce the capacity of the drive, but precautions should run with sufficient capacity. While the pump is running at low speed, motor current is small, but when the user changes frequently water, vacuum pipe network overlying water supply equipment motor will be in frequent, deceleration state, and acceleration and deceleration The current can be slightly more than the rated current of the motor, causing the motor to overheat, therefore, the motor thermal protection is required, the temperature rise due to such frequent, deceleration and accumulated. Electronic thermal protection inside the inverter main function is to protect the hard use, so should be used for the motor thermal relay thermal protection. In the main function of preset aspect, the highest frequency should be based on the nominal frequency of the motor is the maximum operating frequency of the inverter, rise, spin-down time in the case of the PID regulator. Acceleration and deceleration time should be set too short, so as not affect the dynamic response of the decision by the PID regulator, such as the drive itself has a PID regulator main function, as long as PID main function is set at a preset valid, then the set acceleration and deceleration time will automatically lapse. Xinyang PID control tower water supply equipment principle: according to the feedback principle: in order to maintain a physical constant or substantially constant, it should lead the physical and constant comparison, a closed loop system. We want to maintain a constant pressure, so it is necessary to introduce pressure feedback value and given value, thereby forming a closed-loop system. However, the system is controlled by a non-linear characteristics, inertial systems, now and PID control method combining the pressure fluctuations in the use of fuzzy control, in order to speed up response time; smaller PID range when using the pressure to remain static accuracy. This is done by adding PLC intelligent instrument time is now the algorithm can be switched simultaneously to PLC programming time is now pump frequency and frequency between. Practice has proved that this method is feasible, and cost is not high. No negative frequency of water supply equipment in order to maintain constant pressure water supply network, according to the feedback theorem on the management network system installed pressure transducer as feedback element, since the water supply system pipe length, large diameter pipe network charge Pressure is slow, so the system is a big delay system, easy to direct the use of PID regulator control, and participation by way of PLC controlled to achieve the control system regulation.
