固定升降機液壓油不足時，液壓泵會產生吸空現象，導致空氣進入液壓油中，也會產生噪音。液壓油中有其他雜質的時候也會有噪音的情況產生。When the hydraulic oil is insufficient, the hydraulic pump will suck the air, which will cause the air to enter the hydraulic oil. Hydraulic oil in the presence of other impurities, there will be noise generated.
當固定升降機出現噪音的情況時，首先更換液壓油的時候，有時候比較差的液壓油也會導致噪音，所以在選用液壓油的時候也需要注意，盡可能購買質量較好的液壓油。When the noise when the elevator is fixed, when the replacement of hydraulic oil, hydraulic oil, sometimes relatively poor can also cause noise, so in the selection of hydraulic oil also need to pay attention to, as far as possible to buy good quality hydraulic oil.
為了防止在使用和操作的過程中，減少和預防固定升降機出現故障，應該不定期的對升降機進行保養和維修，不定期的檢查升降機的零件，檢查升降機零部件是否有磨損的現象，這樣才能更好的保證升降機的使用和延長升降機的使用壽命。In order to prevent the use and operation of the process, reduce and prevent fixed elevator failure, should not carry out regular maintenance and repair of the elevator, irregular inspection elevator parts, check whether the elevator parts wear phenomenon, so as to better ensure the use of lifts and prolong the service life of the elevator.
