英语翻译设备安装完毕后空载运行4小时,然后分别以50％和100％的物料通过量各测试36小时呃……好吧，这是我翻译的，Af

Run the equipment empty for 4 hours after it has been installed.And then test it for 36 hours separately with 50% and 100% of materials passing rates.
以上是正确翻译,希望会对你有助.
後补; After "the" installation,而且用错字,throughput 用在电讯的 input 和 output,并非实物的通过量.应该改为 passing rates 或 flow rate.
