Sichuan ABB frequency without negative pressure water equipment 华旭智 capable of pumping water tank integrated presentation features ■ constant pressure water supply equipment can replace high water tanks, water towers, pressure is relatively stable to avoid frequent pump startup, high efficiency, low noise. Hulong constant pressure water supply equipment in accordance with national fire standards "fire protection design of tall buildings" and the Ministry of Public Security Fire Standards "performance requirements and test methods for fire pressure water supply equipment" for design and development. Constant pressure water supply equipment products using CAD design center, three-dimensional simulation of manufacturing design system for new product development and design, optimizing product mix, to ensure the quality and speed of new product development. Pump water supply equipment can be cast iron, ductile iron, carbon steel, alloy steel, stainless steel and other materials, casting, and the other can be customized according to specific needs. Constant pressure water supply system is widely used in water conservancy, construction, fire, electricity, environmental protection, petroleum, chemical and other.华旭智 capable of pumping water tank integrated Introduction: intelligent box pump one water tank, tank pump integrated eliminate the negative pressure introduced universal set of functions to avoid interference municipal pipe network pressure. But its function is to regulate the tank by the front pump having drying function. When the water is greater than the municipal water supply, regulating vacuum breaking device on the tank open, air into the tank, so that the original closing of the conditioning tank into a break tank. However, since the vacuum interrupter function device to achieve the destruction of the water supply equipment directly to exposure device, a user can be artificially adjusted, when users cancel their opening function, the conditioning tank will lose its function has become a vacuum interrupter, direct supply equipment elimination of negative function that is not possible, poses a serious threat to water security. Because one of the intelligent box pump tank, pump integrated presentation box with a shut-off function, it is essentially impossible to be fully enclosed operation, there is still the possibility of air entering the water pollution of the water supply system. One intelligent box pump tank, tank pump integrated introduce product standards development and engineering disciplines. Output standards will promote the development of technology and technology standards will play a guiding market and technological developments, regulate the role of development of the industry. Device initial operation, first set pressure protection value according to the local water pipe network water pressure minimum limit; the device is powered automatically placed in working condition. Logo machine control system real-time detection of water pressure and water pressure pipe network users. When low water peak, when the water supply pipe network and quantity, water pressure pipe network pressure to fully meet user requirements, logos machine control system controls the water pump goes to sleep or into the system by the regulator, pressure condition, water users are from the next device road through the tube directly supply the user, saving 100%. Water peak, when the water supply pipe network of foot, low pressure, the emblem of the machine control system according to the needs of the water pump inlet water pressure and water users, frequency soft start the pump, laminated supplement section, much worse, How many make up, that make full use of existing water pipe network pressure, but also to ensure that users required pressure constant. When the water pipe network water pressure drops to protect the pressure value set in advance, the emblem of the machine control system through the pressure limiting protection device to ensure the water pipe network water pressure is no longer declining, straight bottom water pipe network pressure without breaking, pressing user The amount of water has to meet. When the water pipe network water shortage, pressure is inadequate, the device through the computer control system, anti-vacuum device and voltage limiting protection device workers to work together to ensure that the premise does not generate a negative pressure in the water pipe network of water supply to the user. When the system power, restore natural water supply water pipe network; when an incoming call, automatic wake-up device. When the water pipe network is completely without water, the system automatically shut down; when runoff resume normal operation. 1. The use of non-vacuum controller always monitor the municipal pipe network and Compensation tank pressure, when the water pressure, no negative pressure controller to work to ensure that the municipal pipe network water pressure is not affected. 2. The use of energy storage to work to ensure that the water tank to the greatest degree of compensation to the user's network, the inhibition of negative pressure generated to assure municipal pipe network have any effect. 3. The use of energy storage and release of bi-directional compensation adjustment means water pipe network can automatically compensate for continuous water can also pipe network compensation from the pressure regulator role in ensuring that the device on the water pipe network does not produce negative pressure. The unique three-chamber sub-chamber water technology is adapted to the needs of the development of new water supply mode, it is possible to ensure that the water level of the peak of the largest non-negative pressure surge tank of water to compensate the user, in order to protect the high area of ??the user The normal water. Integration of intelligent tank pump modeling Description: Intelligent Integration tank pump water pipeline modeling is based on the user's actual water pressure and flow rate user user actual consumption data of the building height determined by the device table..... .... regulator is a volume of water flow to meet the requirements in accordance with the case estimates if the water line is very thin flow can not meet the water requirements of the volume of water peak period needs to be recalculated regulator recommended formula as follows: V Volume = (Q out -Q feed) △ t ??Q = maximum daily intake of tap water peak into the water Q = maximum daily peak water out of the water users t = maximum duration of peak water tank integrated intelligent pump technical indicators 1, the water flow 0- 1500 M3 / H head 2, the control motor power 0.75 --- 1500KW 3, the number of households 10-10000 household water supply 4, the pressure control range 0.15-1.6MPa 5, the average saving rate of 30-60% 6, sine wave PWM control principle or space vector SVPWM 7, single pump or multiple pump operation mode automatically switches 8, the control method is programmable and PID control 9, overload 150% 60 seconds intelligent integrated tank pump Ordering: Read this manual in detail before ordering. clearly marked with specification, model, quantity and form of packaging of products. The company took the design when required, please provide detailed arguments and pointed: the integration of intelligent water tank with pump size, specifications, head and flow.
