Seiko quality driven Shengbokaisi frequency without negative pressure water supply equipment without negative pressure water equipment series directly with the municipal pipe network is completely closed a new supply model. Municipal pipe network is 0.25Mpa --- 0.3Mpa pressure, negative pressure water equipment is based on the municipal pipe network superimposed on the pressure booster, how much less make up, so to minimize energy consumption, energy savings is quite obvious. But municipal pipe network pressure reaches the set value protection, vacuum suppressors open, releasing an inert gas to suppress the generation of negative pressure, to avoid the device to force water from the pipe network, to protect the safety of municipal pipe network, thus truly no negative water supply. Therefore, the Department of Water Supply Equipment Crystal Lee is really no negative pressure water equipment. The system is closed operation, the complete eradication of secondary pollution, ensure the quality of fresh and hygienic. Unique hydraulic model, light energy saving pumps, precision digital control technology and superior ability to compensate, so Crystal Lee Department of negative pressure water equipment to become a peer leader in energy-efficient than similar products in more than 15%. Application areas: public housing, department stores, shopping centers, office buildings, commercial centers, government buildings, hospitals, hotels, railway stations, airports, water is the second booster pump stations, golf courses, industrial and mining enterprises. Environment: voltage three-phase 380V, frequency 50HZ; ambient temperature is between 0-40 degrees; relative humidity less than 90%, non-condensing; PH value between 5-9 medium, medium temperature 0 --- 100 degrees ; water or similar liquid water; obviously non-corrosive ambient air pollutant gases, water vapor, dust, etc; install no more than 1000 meters above sea level, the foundation does not exceed 5 degrees inclination, indoor installation. Shengbokaisi a frequency without negative pressure water equipment. Directly with municipal pipe network series, municipal pipe network overlying booster. Absolutely assure network impact. 2, the entire system is closed operation, absolutely no water pollution, absolutely no run, run, drip, leak phenomenon wasting water. 3, the effective use of municipal pipe network pressure on the pipe network layers booster, energy-saving effect is very significant. 4, the entire system, without built underground pool and rooftop water tanks, reducing the footprint, easy installation, saving investment. 5, all wetted parts are made of SUS304 food grade stainless steel to protect the health and safety of water supply. 6, a unique digital control technology, superior ability constant, so that no water pressure fluctuations, pressure fluctuations in the positive and negative control 0.01Mpa. 7, configured as a dual drive is equipped with luxury, safety guarantee uninterrupted water supply. The main function of a control system, clear touch-screen display, as the water supply system to provide comprehensive information and functionality. 2, alternating operation function: each pump can periodically take turns running, equally divided between the pump load, in order to convert the pump to extend pump life; 3, to prevent idling function: when there is insufficient municipal pipe network pressure, the system stops functioning, and alert; 4, automatically skip function: When the pump fails, the system automatically skip pump failure, directly next pump operation and alarm; 5, overload protection function: When the pump overload, indicating motor start current exceeds set value, the pump stops running immediately; 6, overpressure protection: ultrahigh pressure, the pump stops running immediately, and alerts; 7, burst pipe protection function: When the water pipes burst pipe leak occurs, automatically shut down; 8, Anhydrous protection: water, water pump stopped immediately, and alerts; 9, water protection: When the municipal water pipe network is not enough, no vacuum starts automatically pay compensation; 10, according to the schedule operation function: according to the schedule set by the pressure to run; 11, record the functioning of the pump: display and save water pumps operating frequency and duration of the contents of the function; 12, anti-jamming function: pump is not running at a certain time, automatically starts the pump function. 13, automatic voltage function: When the dramatic changes in water supply, the water pressure remains stable, to provide users with a comfortable and stable water environment; 14, environmentally friendly energy systems: based on changes in water supply, automatic control of volume and the number of revolutions of the pump can be saving more than 30%. Shengbokaisi stainless steel tanks often used SUS304, SUS316L, SUS444 and other stainless steel plate stamping. General stamping into three dimensions, namely, 1x1 meters, 1x0.5 meters and 0.5x0.5 meters three, surrounding by TIG welding of high strength, light weight, low cost, environmental health and other characteristics.
