一、对供水管路压力调节系统的要求喷头水力性能测试自动控制台不仅要能够完成测试的过程控制,还要保证测试过程中所必须的稳定水源压力,即应有管路水压调节系统(根据管路布置见本刊86.2《喷头测试自动控制系统》图1)。这就要求采用尽量少的电动仪表组成调压系统,以完成5/8″、1″、2″、3″、4″五条管路的自动调节,且对于不同管路,不同喷头、喷咀,包括对于确定的喷头/喷咀组合的不同的试验
First, the water supply pipe pressure regulating system requirements Sprinkler hydraulic performance test automatic console not only to complete the test process control, but also to ensure that the test process must be stable water pressure, that is, there should be pipe pressure regulating system ( According to the pipeline layout, see the magazine 86.2 “nozzle test automatic control system” Figure 1). This requires the use of a minimum of electrical instrumentation to form a pressure regulating system to complete the 5/8 “, 1”, 2 “, 3”, 4 "automatic adjustment of the five pipelines, and for different pipelines, different nozzle, nozzle , Including different tests for a given nozzle / nozzle combination
