1. Start-up procedure of Roots vacuum pump: （1）、启动前级泵。 (1) Start the front pump. （2）、打开前级泵预抽官路商的阀门和罗茨泵进气口上的阀门。 (2) Open the valve of the pre-pumping official and the valve on the intake port of Roots pump. （3）、待系统内的压力达到罗茨真空泵的允许压力后，关闭预抽阀门，起动罗茨真空泵，如无预抽管路及阀门，则待达到起动压力后起动罗茨真空泵，此过程亦可采用压力传感器自动控制，实现整个过程的自动化。 (3) When the pressure in the system reaches the allowable pressure of Roots vacuum pump, close the pre-pumping valve and start the Roots vacuum pump. If there is no pre-pumping pipeline and valve, then start the Roots vacuum pump after the starting pressure is reached. This process can also be automatically controlled by pressure sensor to realize the automation of the whole process. （4）根据真空系统的实际情况，如果不是大的真空系统，则起动前级泵后即可起动罗茨真空泵。如果是较大的真空系统，虽然带溢流阀的罗茨真空泵具有过载保护作用，但这种保护只是对电机的保护，罗茨泵本身仍可因为长时间工作在高压力下，而产生过热卡死，应待前级泵抽到一定压力后再起动罗茨泵。 (4) According to the actual situation of the vacuum system, if it is not a large vacuum system, the Roots vacuum pump can be started after starting the front pump. If it is a large vacuum system, although Roots vacuum pump with relief valve has overload protection, but this protection is only for motor protection, Roots pump itself can still work under high pressure for a long time, resulting in overheating jam, should wait for the front pump pumped to a certain pressure before starting Roots pump.guiwenshi.jk56.org kezishi.jk56.org fengjii.jk56.org fengjix.jk56.org fengjiz.jk56.org fengji.jk56.org |
