我站150米3/时制氧机所配 1-15/50型空压机,是一种结构比较老式的空压机,操作不方便,运转不安全。几年来,我们进行了一些改进,实现了半自控操作。1．用电磁接触器代替手动“转子短接”开关,用时间继电器控制,减少了一个手工操作步骤。另外在炭刷手柄起动位置加了一个限位开关,如果手柄不在起动位置,起动按钮就无效。以前没有限位开关,有时手柄不在起动位置,起动就要“放炮”。2．润滑油泵由链条传动改为电机传动,同时加了一个YT-1226型压力调节器,限制最低工作压力为1公斤/厘米2。如果无油压或油压不到1公斤/厘米2,主机便起动不了。在正常时若油压下落,低于规定数值时,主机便自动停车。
I stand 150 m 3 / hour oxygen machine equipped with 1-15 / 50 air compressor, is a relatively old-fashioned air compressor, the operation is not convenient, unsafe operation. Over the years, we made some improvements to achieve a semi-automatic operation. 1. Using a magnetic contactor instead of the manual “rotor shorting” switch, with time relay control, reduces the number of manual steps. In addition carbon brush handle start position plus a limit switch, if the handle is not in the start position, the start button is invalid. There was no limit switch before, and sometimes the handle is not in the starting position, start to “blasting.” 2. Lube pump from the chain drive to the motor drive, while adding a YT-1226-type pressure regulator, limiting the minimum working pressure of 1 kg / cm 2. If no oil pressure or hydraulic pressure less than 1 kg / cm 2, the host will not start. If the normal oil pressure drop below the required value, the host will automatically stop.
