Yancheng no negative pressure water equipment manufacturers

 What is no negative pressure water supply equipment is a pressurized municipal water supply network connection, the residual pressure in the municipal pipe network, based on the series directly overlying water supply unit and ensure that the municipal water supply pipe network pressure of not less than the set pressure protection ( 0 can be relative pressure pressure pressure is called negative pressure is less than 0) in the second pressurized water supply equipment. Pipe network layers (no vacuum) water equipment is the core of the secondary pressurized water system is running how to prevent negative pressure produced, eliminating the effects of plant operation on municipal pipe network, to ensure without affecting nearby water users to achieve safe, reliable, stable, sustainable water supply. Negative pressure water equipment has been called pipe network overlying water supply equipment, currently on the market are mainly classified tank negative pressure water equipment and box-type negative pressure water equipment without negative pressure water equipment currently used on the market No negative pressure water equipment are two kinds: the steady flow tank, water tank regulator. Steady flow tank tank negative pressure water equipment installed before the pump pressure sealed cans, cans additional internal or external steady flow compensator (also known as "vacuum to eliminate"), the steady flow through the pump suction tank, pressurized supplied to the user, by regulation of the steady flow compensation, reducing the impact on the public water supply network. This way no reserves of water, while urban public water supply pipe network without water, without water prone to the phenomenon. Regulating water tank that has no way of adjusting the pressure tank, plus has a steady flow of internal compensation, by electronic control device, so that the water in the tank to adjust the cycle twice a day at least, ensure the quality of the same. When the water pressure conditions of municipal pipe network to meet the requirements of negative pressure water directly from municipal water pipe network; otherwise, the water tank from the regulator. This approach has a certain reserve of water, can be used for water supply network unstable region, but due to the presence of tanks and manhole, according to the provisions still regularly cleaned and disinfected (data). Negative pressure water equipment installation instructions: 1, the equipment should be installed on the basis of the strength of not less than C20 and drainage facilities and maintenance around the left channel; 2, equipment installation site should be selected in relatively dry environment, avoid outdoor environment in order to avoid damage to electrical components; 3, before installing the pump should be carefully examined in the presence of a hard object abortion, to avoid damage to the impeller and the pump is running; 4, install piping shall not be allowed on the pump, the pump in order to avoid distortion, affecting the normal operation; 5, according to the order of installation drawings, the connection of the seal, can not be forcibly install large diameter mains need to add support to avoid stress; 6, tighten the bolt, so as not to affect the performance of the pump vibration when starting ; 7, at the inlet and outlet piping pump installation control valve, pressure gauge installed in the vicinity of the pump outlet to control the pump within the rated operating conditions to ensure the normal use of the pump; 8, the experimental pressure piping system rated pressure 1.5 times, and continued for 5 minutes or more. In the pressure test process piping systems shall not have cracks and drop, leakage, seepage phenomenon; 9, exhaust pipe loaded check valve should be installed outside the gate; 10, the installation of the pump into a rigid connection to the installation and flexible coupling installed. The advantages of a negative pressure water equipment, saving the cost of equipment investment is relatively small footprint. Not only invest savings, but also on the water pipe network water pressure once fully utilized. Can be used in selecting the appropriate pressure pump is reduced, prompting the equipment investment cost savings obtained. Secondly, the system footprint to get savings on conservation land full advantage of further housing footprint will be enhanced to meet the conservation of land resources, the effect of our requirements. 2, clean pollution, water supply equipment, system settings are all sealed and water from a water pipe CAPE until the user taps the home, and therefore, does not appear pollutant water supply system of the phenomenon. Water is not directly connected to the air thick, food-grade stainless steel for overcurrent but not for production, so there is no water pollution phenomenon. 3, significant energy savings, links are usually equipment and water pipe network are directly connected in series, which is in the water plant for the next water supply pipe network pressure conditions superimposed on the desired pressure, according to the lack of pressure, appropriate The increase, prompting the residual pressure pipe network to be fully utilized. Then low water peak stage, the device can not run, there will be significant energy savings previews. 4, easy to install. Because no negative overlying water supply complete sets of equipment belonging to the supply system, so users only need to import and export can be used to connect pipes, short construction period, and easy to install. 5, lower operating costs. Due to the use of smaller pressure pump in the selection process, and can be associated with the use of the water pump method, in the city of low water peak, able to take advantage of the city once the water pressure, the pump can not be started or only a pump to start the method to achieve urban water demand. When the water comes before the peak of the other pump starts. Therefore, the device is running low energy consumption will be formed to promote effectively reduce operating costs. 6, does not affect the status of the water supply during power outages occur. Due to public water supply network and user network device is directly connected, so when a power outage, although the pressure pump to stop the run, but once the water plant water pressure on the water needs can be met. 7, to facilitate the subsequent management. Because no negative overlying water supply equipment belonging microcomputer automatic frequency control, and therefore have the power equipment automatically shut down, calls devices automatically boot the effect of fault detection, diagnosis and alarm reminders technology better, prompting equipment management and maintenance The advantage of the presence of relatively simple process. Secondly, because without contamination, so there is no cleaning work. No negative pressure water supply equipment a range of applications, high-rise buildings, residential areas, villas and other living water. Daily water 2, enterprises, institutions, hotels, office buildings, department stores, large sauna, hospitals, schools, stadiums, golf courses, airports and other places. 3, manufacturing, cleaning equipment, food industry, factories, industrial process water. 3, has been built in the pool, you can use negative pressure water equipment and pool shared water supply, further energy saving; 4, the original pressure water supply equipment to transform, you can take advantage of the existing pressure tank; 5, various cycling system, in the middle of the water plant booster pump station; 6. Other: old pool water and other forms of reconstruction of water supply; 7, irrigation systems;
