汽轮机机头上的固定式转速表,是汽轮机运行状态的主要监视仪表之一,我厂的3000kW背压式汽轮机机头上的转速表,自安装投产后,转速表固定套的上下接合面就存在漏油问题,如将固定套上下接合面漏油消除,转速表内部便进油.表内油满了以后,油便从玻璃表面下部向外漏出.表内进油后,表内离心机构旋转中产生的阻力增大,
The fixed tachometer on the turbine head is one of the main monitoring instruments for the running state of the steam turbine. The tachometer on the head of the 3000kW back pressure turbine of our factory, since the installation and commissioning, the upper and lower joints of the tachometer fixing sleeve There is the problem of oil leakage, such as the fixed sleeve upper and lower joints to eliminate oil leakage, the tachometer will be the internal oil into the table after the oil is full, the oil will leak out from the lower part of the glass surface. Resistance generated during rotation increases,
