Frequency of life feed pump features: a, automatic isolation valves or throttling device (optional): used to isolate municipal water, can be arbitrarily set operating pressure, when the municipal water pressure is lower than this value, the isolation device action switch to the water tank or pressure tank water supply. Regulators may also consider water supply equipment throttling device instead of using inexpensive isolation valve, limiting the maximum water flow, inadequate water supply compensated in part by the water tank. Regulator supply equipment b, water tank: Water running water tank is filled with all the volume, because no compressed air energy storage, buffering effect of various shocks and dynamic compensation of municipal water as effective as a buffer tank. But when the municipal water pressure is too low, the water tank effluent (water) is greater than the amount of water, water storage tank volume can all be used to compensate for the lack of municipal water. During the water tank to provide compensation for the amount of water the air by vacuum suppressor automatically enters the tank, the regulator can supply equipment to compete avoid causing depression suction pipe network (the so-called no vacuum suction). Water tank can be used in series with the water line. c, pressure tank: generally reinforced concrete structure, with water tank to work on the same principle, because of the large volume of municipal water supply has a good load shifting role for a variety of municipal water situation throughout the country. Regulator supply equipment for some reason when the municipal water supply pipe network pressure tank can be provided without water during a certain time of water supply sources for customers that require high reliability of water supply applications. Regulated water supply equipment d, pump unit: selection of the company has a non-overloading characteristics of pumps, which can be adapted to the pressure change operating characteristics over a wide range of municipal water, and does not produce overload. e, pressure tank: its role and usually twice a pressurized water supply equipment in the pressure tank the same standard product design using miniature diaphragm pressure tank, the main advantage of its packing function, automatic energy-saving equipment in favor of intelligent control. f, frequency control cabinet: a choice of full conversion technology solutions that all pumps are used frequency drag, but also be part of the inverter technology program (only one pump for frequency control drag). g, a bypass line: If the municipal water supply equipment regulator usually meet the requirements of water vapor, only the peak pressure in the water supply shortage, loadable bypass pipe so that the municipal water and pressurized water directly automatic switching operation. When non-fire state, the use of TH-F series automatic inspection of water supply equipment, complete sets of automatic fire control equipment consisting of inspection, fire pumps can do automatic inspection operation. Automatic inspection cycle for a few hours to several hundred hours, optionally, the clock cycle starts automatically with manual inspection procedures and inspection functions. Main circuit voltage supply equipment inspection digital intelligent fire inspection controller will detect fire control cabinet after confirmation of normal, one by one driven fire pump to make low-speed operation, when the drive power is very small, about the pump motor rated power of about one percent, so the significant energy saving. Due to the low speed, so it will not pressurized water supply pipe network. If you run the command while receiving the fire inspection, the local control unit will immediately interrupt polling operation, the control device to power-frequency-driven fire pump into the fire command is run. Regulator supply equipment only to the next period and no inspection when the fire occurred, began running a new inspection process. When the inspection, if the pump fails fault alarm information will be given. When an input overvoltage, undervoltage, phase, output over-current, TH-F Series controller will issue a warning message to the fire center a short circuit. This result ensures automatic inspection of the fire pump will not rust, rust phenomenon, the fire water supply equipment "idea that day, military forces while" a reality. The device also has a standby pump automatically swap, when the main pump failure, the standby pump automatically input. Standby power automatic mutual investment, when the main power fails, the standby power is automatically put into other functions, TH-F series digital controllers intelligent fire patrol fire automatic control equipment will patrol all of the above features provide remote data, image monitoring, fault alarm, message printing. Frequency of life to illustrate a water pump, pressure regulator device according to mid-August 1996 Hua Renshi Republic Ministry of Construction [1996] No. 108 development and design of the new booster regulator device while meeting 98S205 (original 98S176) provisions . Second, the booster regulator device to resolve the temporary high-pressure fire water supply system established by high fire water tank, which can not meet the requirements set the height of the most negative point of the system should be set up hydrostatic pressurization facilities, equipment design and preparation of water regulator a dedicated booster regulator for Fire Equipment (hereinafter referred to as "equipment"). Third, the device is suitable for multi-storey and high-rise construction projects include Fire Hydrant System and pressurized wet facilities required sprinkler systems and other fire water supply, power supply equipment life water supply system. Fourth, the "Equipment" by diaphragm pressure tank, pump, electric control boxes, instrumentation, pipe fittings and other components. Five regulator water supply equipment, the equipment in compliance with "ridiculed layer civil design for fire protection" (referred to as "high regulation") GB50045-95 and "pressure water design specifications", CECS76: 95 technical parameters specified design. Frequency regulator water supply equipment life to choose a pump selection based on the fundamental basis of life inverter is designed to pump water flow and water pressure (water head), and the need to consider changes in the type of traffic to use. Continuous voltage supply equipment: a day with little normal leakage flow is zero when the network itself or on maintaining a certain amount of traffic, for example, large hotels, restaurants, industrial and mining enterprises pressurized systems. Intermittent: water trough for a long time and the flow is very small or zero, for example: a small office building, office, commercial and residential, various types of residential, and industrial water supply equipment regulator should also be considered, such as a certain period of time in the water various factors changes in traffic flow and changes in different seasons, different in different regions, such as water. Regulated water supply equipment fire water sprinkler equipment and water supply equipment in general pneumatic supply equipment should be selected because of its long-term holding pressure in the system state, no flow changes, water supply equipment, pneumatic tube leak can cope with the general, and adding a Vice small flow pump, usually do not need to start the main pump, saving energy. Regulated water supply equipment life conversion water supply equipment supply equipment selection or pneumatic supply equipment can be, both have their advantages. Regulators conversion water supply equipment supply equipment advantages: You can adjust the constant water supply and constant voltage constant value within a certain range accuracy is generally less than 0.02MPa, frequency control is an efficient energy saving methods and the usual pressure water supply equipment Compared to the average efficiency of 20%, in addition, a small start-rush current and frequency of the pump 盍 impact is small, little noise at low speed. Advantages supply equipment pneumatic regulator water supply equipment: cost is relatively low, the control system technology is simple, convenient service and maintenance easy. Frequency of life related to the pump design conditions 1, pressure tank working pressure: 0.6MPa, 1.0MPa, 1.6MPa. 2, fire water storage volume is greater than the pressure tank: 150L, ??300L, 450L. 3, the regulator is greater than the volume of water pressure tank 50L. Regulator supply equipment 4, buffered water pressure tank volume pressure is 0.02 ~ 0.03MPa, the volume of water pressure regulator is 0.05 ~ 0.06MPa. 5, the working pressure ratio: a b value of 0.6 ~ 40 ℃. Frequency of life to the pump must have the following two functions: 1, so that the most negative point of fire water piping system is always pressure required to fire; regulator supply equipment 2, the inner pressure tank always have 30 seconds to fire water reservoir. Use pressure tank set P1, P2, Ps1, Ps2 operating pressure, control pump operating conditions, to the supercharger and regulation functions. P1 is the most negative point of the fire required pressure (MPa), P2 for the fire pump starting pressure (MPa), Ps1 regulator pump for starting pressure (MPa), Ps2 to stop the pump regulator pump pressure (MPa) A regulated supply equipment urban and rural residents living water is widely used in buildings, living quarters and various urban and rural water supply, and effective way to eliminate the breeding, red worms breeding of bacteria, for the majority of households to provide cleaner, better quality drinking water, both to ensure the safety of the residents of water , but also saves energy, saves expenses.
