    • A mixed air amount alarm device is provided which determines the amount of air present in a hydraulic circuit between a hydraulic pressure source and an instrument driven by hydraulic pressure, and produces an alarm if the air amount is excessive, a situation is prevented in which an alarm is produced or not produced according to change of the air amount (volume) resulting from temperature change, and it is possible to stop an alarm if potential danger disappears and a safe state is recovered due to spontaneous release of air out of the hydraulic circuit. If the air amount is determined excessive, this is stored in a nonvolatile memory, and even if air amount excessiveness determination is not made at the next activation of the hydraulic device, the content of the nonvolatile memory is checked and an alarm is produced if air amount excessiveness determination has not been made before. It is preferable to add a function of erasing the air amount excessiveness determination history when specific conditions are met, for example, if the fluid temperature of hydraulic fluid or its inferred value is equal to or higher than a predetermined value, and in this state, the air amount is determined to be at a permissible level.
    • 提供了一种混合空气量报警装置,其确定存在于液压源和由液压驱动的仪器之间的液压回路中的空气量,并且如果空气量过大则产生报警,防止其中 根据温度变化引起的空气量(体积)的变化而产生或不产生报警,并且如果潜在危险消失并且由于空气从液压回路自发释放而恢复安全状态,则可以停止报警 。 如果空气量被确定为过大,则将其存储在非易失性存储器中,并且即使在下一次启动液压装置时没有进行空气量过量确定,则检查非易失性存储器的内容,并且如果空气 以前没有做出过量的判定。 优选地,当满足特定条件时,例如如果液压流体的流体温度或其推断值等于或高于预定值,则添加擦除空气量过剩判定历史的功能,并且在该状态下, 空气量被确定为允许的水平。
