工作温度和回水温度对水喷射泵性能的影响

Effect of water supply and return temperature on performances of water injector

比较了其他参数相同而流体工作温度和回水温度分别变化10℃时,二者对水喷射泵性能的影响。结果表明,回水温度变化对水喷射泵的截面比和性能影响较大,因此在供热系统运行中应尽量减小回水温度的波动。

Compares the effects when water supply and return temperatures vary 10 ℃ respectively while other parameters remain unchanged.As a result,the water return temperature affects cross-section area ratio and performances of the injector more heavily,hence the water return temperature should be kept as steady as possible during operation of a heating system.
