水喷射泵在高区直连系统中的应用

在低区供热管网上直连高区加压机组供热工程中,将水喷射泵安装在高区用户与低区管网回水干管的分支点,既起到了对高区回水节流降压的作用,使其不影响低压供热管网上其他用户的供热效果,又将这部分常规方法用阀门节流白白浪费的能量利用起来,使水喷射泵起到了管网回水加压泵的作用,在不消耗任何额外能量的情况下提升了管网整体供热能力,增加了管网的水力稳定性,减少了管网的改造投资,达到了节能供热的目的。

Application of Water Jet Pump in High-rise Building Direct-connected System

Install water jet pump at the point where return pipe of high-rise building and return main of low pressure pipe network connected. It not only reduces the head of return pipe of high-rise building, avoids affecting the heating effect of other users on the low pressure pipe network, but also utilizes the energy which would be wasted completely if adopt the traditional method-using the valve to throttle the return water flow of high-rise building. The water jet pump here has the equal function with return water booster. It increases the heating capability of the heat pipe network, enhances the hydraulic stability, reduces the investment on pipe network rebuilding, and achieves the aim of energy conservation in heating.
