Yinchuan combined stainless steel water tank has complete qualification
Frequency conversion pressurization equipment without negative pressure is suitable for farmland irrigation system. The modeling of non negative pressure variable frequency pressurization equipment is determined according to the data of the user's water pipeline, pressure and flow, actual water consumption of the user, actual water consumption of the user, and the height of the building. The regulator volume for the meter of the non negative pressure water supply equipment is estimated according to the condition that the tap water flow meets the requirements. If the water pipeline is very thin, the flow can not meet the peak water consumption According to the water requirement, the volume of the regulator needs to be recalculated. There is no negative pressure variable frequency pressurization equipment of 0.15 ~ 2.0MP, the water supply height is 10-200M, and the water supply per hour of a single set of equipment is 10 ~ 50000m3 / h, which can be used for supporting transformation of large, medium and small tap water; it can be used for production, living and office water of enterprises, residential areas and rural areas. No negative pressure variable frequency pressurization equipment four technology upgrade instructions: eliminate negative pressure technology double insurance; on the basis of the original negative pressure elimination technology, by a negative pressure suppressor work. Product introduction
The water from the tap water pipe network of the variable frequency water supply equipment directly enters the regulating tank, and the air in the tank is discharged from the vacuum eliminator. After the water is full, the vacuum eliminator will automatically close. When the tap water can meet the water pressure and water requirements, the equipment directly supplies water to the water pipe network through the bypass check valve; when the pressure of the tap water pipe network cannot meet the water demand, the system will give the starting signal through the pressure sensor (or pressure controller, electric contact pressure gauge) to start the pump operation. When the water is supplied by the pump, if the water quantity of the tap water pipe network is greater than the flow of the water pump, the system will keep normal water supply; at the peak of water consumption, if the water quantity of the water pipe network is less than the flow of the water pump, the water in the regulating tank can still supply water normally as a supplementary source. At this time, the air enters the regulating tank through the vacuum eliminator, eliminating the negative pressure of the water pipe network. After the peak period of water consumption, the system returns to normal Status of. If the water level in the regulating tank continuously drops due to the water cut-off of the tap water pipe network, the liquid level detector will give the pump shutdown signal to protect the water pump unit.
High quality of water supply: the equipment adopts constant pressure control at the outlet of water pump. No matter how the water consumption of the system changes, the outlet pressure of the pipeline can be kept constant. Reliable operation: the equipment adopts imported frequency converter and domestic high-quality water pump, with perfect protection function and automatic and manual conversion function, which makes the operation very reliable. High efficiency and energy saving: the equipment can adjust the speed of water pump according to the change of water consumption of users, so that the water pump always works in the high efficiency area, and the electricity saving effect is obvious, which can save 35% of electricity than the constant speed pump. Simple operation: the equipment is fully automatic control, and the operator only needs to switch the switch of the electric control cabinet to realize the working conditions required by users. The whole set of equipment only needs one set of control cabinet and human pump unit, so it is very convenient to install. Extend the service life of water pump and motor: it can reliably realize soft start for multiple pump groups, and operate in turn, which greatly extends the service life of water pump and motor. Application range: it can supply 5 ~ 5000 t / h.
The frequency conversion water supply equipment is generally composed of buffer tank, water pump unit, air pressure tank control cabinet and control instrument. The description of each part is as follows: A. buffer tank: it is the air pressure tank connected to the equipment entrance, referred to as the buffer tank. When the water supply is running, the volume of the tank is compressed air, and the compressed air is used to store energy, which has a good mitigation effect on all kinds of sudden impact, and it also has a good effect on municipal administration Water supply has a certain dynamic compensation effect. There are two kinds of buffer tanks with different structures. The diaphragm buffer tank is made of natural rubber diaphragm material, which is more conducive to maintaining the water quality standard because it is completely sealed. The inner wall of ordinary steel buffer tank is coated with anti-corrosion coating meeting the hygienic standard, but it will contact with the outside air during air replenishment. The buffer tank can be used in series or in parallel (the inlet and outlet water is the same pipe, which is connected with the municipal pipeline as a branch).
b. Pump unit: select the pump with non Overload Characteristics of our company, its working characteristics can adapt to the pressure change in a large range of water source, and will not produce overload phenomenon. C. air pressure tank: its function is the same as that of the ordinary two-stage pressurized water supply equipment. The diaphragm type micro air pressure tank used in this series of standard products mainly uses its pressure maintaining function, which is conducive to the intelligent automatic energy-saving control of the equipment. D. frequency conversion control cabinet: full frequency conversion control system can be adopted, that is, all pumps are driven by frequency conversion speed regulation, or partial frequency conversion control system can be adopted (only one pump of sample standard product is driven by frequency conversion speed regulation). E. bypass pipeline: if the municipal water supply can meet the water pressure requirements at ordinary times, and the pressure is insufficient only at the peak of water supply, the bypass pipeline can be loaded to realize the automatic switching operation of municipal pull-down water supply and pressurized water supply.
1. The intelligent frequency conversion non negative pressure water supply mode is selected, which does not need to build underground water tank and high water tank. The secondary pressure pump is directly connected to the water supply network from the water supply network. The microcomputer automatic control and automatic adjustment can ensure that the water pipe does not produce negative pressure, and it can also make full use of the original pressure of the tap water to achieve the purpose of energy saving (power saving can reach 50% - 95%). The frequency of the negative pressure feedback system of the microcomputer is used to adjust the frequency of the water inlet pipe network. Firstly, according to the actual working pressure of the water point, the actual pressure of the outlet pipe is detected and compared with the set pressure. If the actual pressure is higher than the set pressure, the frequency converter frequency will be reduced, otherwise, the frequency converter frequency will be increased. The microcomputer can detect the pressure of the pipe network at any time, and the calculation speed is fast, and the adjustment speed is also instantaneous, so as to ensure that the pressure of the pipe network is always maintained at the set pressure point. In addition, through the negative pressure feedback suppression system, the equipment can be directly connected with the tap water. Due to the superposition principle of the water pump, the equipment can make full use of the original pressure of the tap water. (1) When the municipal pipe network is under high pressure, the equipment is in shutdown state, and the municipal water source directly supplies water to the user pipe network through the buffer tank and bypass pipeline. (2) when the municipal pipe network is under pressure, the frequency conversion water supply equipment of Ningxia Jiquan will start automatically. On the basis of the original non water pressure, the frequency conversion speed regulation pressurization (frequency conversion) water supply is based on the principle of "how much difference, how much compensation". Therefore, in the full flow range, it not only meets the needs of users for frequency conversion water supply, but also realizes efficient and energy-saving operation. In the process of running the closed tank, the fresh water will not be polluted. (3) in the operation of frequency conversion water supply equipment in Ningxia, the volume of buffer tank is compressed air (its pressure is the same as that of municipal water pressure), so a certain pressure potential energy is stored. By this energy storage, the impact of various impacts on municipal water source can be greatly reduced, and the dynamic peak shaving compensation function is provided for municipal water supply.
