在柴油机出厂试验中,为节省设备投资,需要使一台SYZZ型转速油耗自动测量仪,对多台柴油机的燃油消耗量进行测量。其中关键是要解决燃油的切换问题。我厂于1983年设计试制成功了集装块式燃油切换装置,用一台SYZZ测量仪,可轮流对四台柴油机进行燃油消耗量的测量。切换装置的原理框图见图1。如图所示,采用了四只22E_2-B4B常闭湿式微型电磁阔和四只22E_2-B4BH常通湿式微型电磁阀。八只电磁阀装成如图2所示、外形为200×130×60mm~3的集装块,结构紧凑,可以安装在电气控制柜内。
Diesel engine in the factory test, in order to save investment in equipment, you need to make a SYZZ-speed fuel consumption automatic measuring instrument, the fuel consumption of more than one diesel engine to measure. The key is to solve the fuel switching problem. I plant in 1983, the successful trial design block assembly-type fuel switching device, with a SYZZ measuring instrument, can take turns on the four diesel fuel consumption measurement. Switching device block diagram shown in Figure 1. As shown, the use of four 22E_2-B4B normally closed wet micro-electromagnetic and four 22E_2-B4BH often pass the wet micro-solenoid valve. Eight solenoid valve installed as shown in Figure 2, the shape of 200 × 130 × 60mm ~ 3 assembly block, compact structure, can be installed in the electrical control cabinet.
