Unit test run is a comprehensive assessment of single equipment according to the specified time, including unit no-load test run and load test run. The single load test run is only carried out for the equipment that does not need linkage and the equipment that requires single load test according to the load linkage test run regulations.

从某种意义上讲，单体试运转主要是考核机械部分。设备单体试运转的顺序是：先手动，后电动；先点动，后连续：先低速．后中、高速。无负苟联动试运转主要是检查整条生产线或联动机组中各设备相互配合及按工艺流程的动作程序是否正确，同时也检查连锁装置是否灵敏可靠．信号装置是否准确无误。

In a sense, the single test run is mainly to examine the mechanical part. The test run sequence of single equipment is: first manual, then electric; first inching, then continuous: first low speed, then medium and high speed. The non negative linkage test run is mainly to check whether the equipment in the whole production line or linkage unit cooperate with each other and the action procedure according to the technological process is correct. At the same time, it is also to check whether the interlocking device is sensitive and reliable and whether the signal device is accurate.

无负荷联动试运转应按设计规定的联动程序进行或模拟进行。从某种意义上讲，无负荷联动试运转主要是考核电气的联锁。

The no-load linkage test run shall be carried out according to the linkage program or simulation specified in the design. In a sense, no-load linkage test run is mainly to examine the electrical interlock.

负荷联动试运转是在投料的情况下，考核设备安装工程的质量，考核设备的性能和生产能力，检验设计是否符合和满足正常生产的要求。塑料袋质量优良，实惠，销售广泛，欢迎新老客户前来订购。
