Now a single nozzle and multi-nozzle comparison of the circumstances of the well water flow and pressure to work the same (ie equal to the pump motor power consumption). Set single-nozzle exit radius. Jet column length h, then the nozzle 8,<a href="http://www.ghdstijltang.net" target="_blank" class="postlink">ghd stijltang</a>, a cross-sectional area, perimeter surface area of the jet L = 2 F = Lh = 2 threat. N If more than one spray nozzle to fine,<a href="http://www.uggsbotas.com" target="_blank" class="postlink">ugg botas</a>, and make cross-sectional area of nozzles n is equal to the cross-sectional area of a single nozzle. The small nozzle radius r, cross-section area, perimeter f, is also similar to long water column, then H = s r =- gains and blue printed M == V ... = / n such a small total circumference of the nozzle length Lf is: \can increase the contact area with the gas jet and multi-pumping, they are able to improve pumping efficiency. Some information on the number of nozzles for 4 ~ l9 months, taking into account production, friction and other factors. Actually use more nozzles 4 to 9. In improved water jet air ejector nozzles with a single long pipe, a total of more than a long pipe nozzle, as well as long multi-nozzle with multiple pipes, as shown in Figure 6, the multi-nozzle-type exhaust pipes and more efficient the highest, but the production process more complicated. Figure 6 Seven seven pipe nozzle water jet air ejector 3 short pipe water jet air ejector improved as shown in Figure 1 the actual effect of the short pipe water jet air ejector exhaust not only kill low efficiency, and = second nozzle is easy to cavitation damage, as shown in Figure 7, the secondary damage to the nozzle, made from 8mm thick steel plate, only to run for four years. The inner circle to affect the generation of cavitation into the honeycomb. Therefore,<a href="http://www.ghdglaetteisen-guenstig.com" target="_blank" class="postlink">GHD glätteisen günstig</a>, we use the opportunity to overhaul, to design improvements as long as shown in Figure 8, the exhaust pipe device. Improved extraction device to retain only the suction chamber (due to changes in the suction chamber to be foundry processing, heavy workload), and contraction of pipe, removed the secondary nozzle and diffuser. Changing a nozzle, lengthened the pipes, wells will then seal the heater connected to the drain pipe, so that the exhaust Compared with the original, not only greatly simplifies the structure. Thrown against a bad nozzle cavitation phenomenon, and things improve efficiency, reduce energy consumption, as shown in Table 1. 3 (57) water jet air ejector improved method l39 ・ ■ Figure 7 Figure 8 damage to the secondary nozzles improved the long pipes water jet air ejector Table i Comparison of the two machines pumping power performance indicators of water work Xia Xuan pressure pumping pressure floating empty. 【Amount of power consumption of water jet pumping unit. 【Din type 0dW1 (M) body H (h Ⅱ) Island (s, I) (kw ・ h / ks) Short cried pipe smoke. 【Device 500 × 10-14.5 × 10 -= 2.80Xl ● 3.6 shout long pipe smoke. (Control 502.9 × l0'14 .5 × l ● 9.12Xl0. L1.62 be seen from Table l, in similar conditions, the length of pipe water jet air ejector is a short amount of suction air pipe 2 .9 times, and long exhaust pipes are not device power consumption to a unit of the short half pipe exhaust device, only d5, due to the long pipes, suction air exhaust device, high efficiency, on the one hand condenser vacuum to improve, to make baked lower power increases. make more power on the other hand Turbine faster boot time, so start early and with the multi-turbine power generation. If a station 200MW units, due to reduced power vacuum when asked to accelerate 5 minutes. can advance more power i-6 万 kW ・ h around the exhaust pipes is also due to the long low-consumption devices unit before, put the fire pump can greatly reduce power consumption, a 100MW unit fire pump can be saving a year 2l million kw ・ ht to cancel the second injection well and clarity, there is no clarity solid jet phenomenon of cavitation damage. the air ejector safe and reliable, thus improving the long pipes after the water jet air ejector to achieve an efficient energy security purposes. Similarly, Figure 2, Figure 3, Figure 4 types of water jet air ejector can be improved with reference to the above steps, select the appropriate nozzle and pipe processing,<a href="http://www.uggs-ireland.com" target="_blank" class="postlink">uggs ireland</a>, will seal the heater exhaust pipe connected to the proper height diffuser , adjust the water pressure, but also can achieve good results.
