Ningxia Jiquan water tank frequency conversion water supply equipment service quality
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.
The energy saving point of constant pressure water supply equipment with frequency conversion and speed regulation is increased. When the pressure and flow of tap water is insufficient, the equipment collects the water quantity and pressure signal through the detection device in the system, feeds back in real time, and automatically adjusts the negative pressure of the pipe network through the microcomputer control, so as to ensure that the equipment does not have any impact on the urban pipe network. 2. Intelligent frequency conversion non negative pressure equipment, it is directly superposed by municipal water supply, fully closed system, so there is no secondary pollution of the main link, to ensure the water quality safety in the water supply system. At the same time, the equipment itself adopts sus food grade stainless steel high-quality material configuration, which completely eliminates the secondary pollution of the pressurized water supply equipment in the pipe network of the secondary pressure water supply system. The whole water supply system is safe and reliable, and it is a real sanitary and environmental protection green product. 3. Investment: the intelligent frequency conversion non negative pressure water supply equipment can be directly connected to any pipe network with insufficient tap water pressure for pressurized water supply. There is no need to build underground pool and high-level water tank, and the disinfection equipment due to secondary pollution can also be omitted.
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.
To control the generation of negative pressure, an emergency air intake one-way channel is added to eliminate negative pressure; two kinds of negative pressure elimination functions, when the suppressor can not completely eliminate the negative pressure or failure, the other emergency air inlet channel to eliminate negative pressure will be opened immediately and the negative pressure will be completely eliminated. No negative pressure variable frequency pressurization equipment water detection dual protection; when the municipal pipe network water cut off, the water level in the steady flow tank drops, and the liquid level sensor detects no water signal, it immediately gives the signal to the frequency converter to stop the pump and protect the pump, so as to prevent the motor from burning down, and the water pump will automatically resume the water supply when the water comes. The second kind of protection: when the liquid level sensor fails, the electric contact pressure gauge under the non negative pressure steady flow tank works; when the pressure gauge detects that the inlet pressure of the water pump drops, the set pressure; the pressure signal is fed back to the frequency converter to make the water pump work at reduced frequency immediately until the motor is shut down, so as to protect the water pump. When the water comes, the water pump will automatically resume water supply. The outlet channel of water pump of Jiquan rural water supply equipment adopts special lengthened big moon elbow. (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 Jiquan, Ningxia, the volume of the buffer tank is compressed air (the pressure is the same as the 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 the municipal water supply.
