利用现代油液分析技术对高压锅炉给水泵状态监测和故障诊断已经被广泛用于石化公司.在过去的一年的监测中,通过对油液的理化指标分析,铁谱分析,结果表明磨损浓度没有大的变化,浓度的波动主要由于换油.进一步对磨损磨粒进行分析,表明机械摩擦副处于稳定阶段.综合研究表明油液分析技术可以显著提高设备状态监测的效率.

Since 2006,the rapid development of wind power generation in China caused great challenges to qualification of technical staff,especially over 80 000 wind power service technicians (WPST) are needed t
When typical pitch control widely applied to onshore wind turbinesis applied to a floating wind turbine,the tower oscillation of the floating wind turbine is increased by the rotor thrust change.This
The aim of this paper is to explore the effective capacity building program for community based renewable energy project development in Japan.After enforcement of Feed-in Tariff in 2012,the number of
Steel support structures (towers,monopiles,etc.) are among the most costly components of wind turbines.As a consequence,all efforts have to be made to use cost-optimized solutions for specific wind tu
This paper discussed the strain of the blade of the wind turbine caused by the aerodynamic force,the centrifugal force and the coupling of the aerodynamic force and the centrifugal force using the fin
The pitch,yaw and spindle of wind turbine generator set,as well as wind turbine generator bearing are all lubricated by grease.Currently,the waste grease is usually collected by an oil bottle.The cons
There are rich wind,hydro,coal and other energy resources in Northwest China,which is also the most important wind power,hydropower and coal bases in China.To promote efficient accommodation of large-
本文介绍了一种简便的针对1.5MW 双馈风电机组的低压穿越改造方法,该方法不需要对机组的主控系统、变桨系统以及变频器进行任何改造,只要在机组并网点处串入一台低压穿越控制设备,就可使风电机组满足GB19963-2011要求的低压穿越能力.该低压穿越控制设备由主功率旁路和电压支撑回路组成,主功率旁路在正常工况下传输机组的发电功率,在电网故障工况下,主功率旁路快速关断,同时电压支撑回路在向电网端输出无功
此风电场高压侧(110kV)接线为线路-变压器组接线,35kV 母线侧共接入4回集电线路,其中一期工程为2回为架空线路,二期工程为2回以电缆为主的线路.一期风电场为限制电容电流,配置了消弧消谐装置,二期投运后,线路电容电流过大,因此取消了消弧消谐装置(国内厂家生产的消弧消谐装置,没有质量保证,该类产品已被国家电力部门取缔使用),配置了低电阻接地方式.由于一期工程为全架空线路,二期工程以电缆为主线路
风电机组变桨、偏航、主轴和发电机轴承等使用油脂润滑,目前采用集油瓶收集废旧油脂方法,轴承内旧油脂不能有效清理,变质硬化,轴承润滑失效.本文指出了现行的风电轴承废旧油脂清除方法及严重缺陷,重点对风电轴承废油脂自动清除及集中回收系统的详细介绍。风电轴承废油脂自动清除及集中回收系统结构组成: 液压泵、电磁换向阀、吸排脂器、废油回收器、监控器、传感器和管路附件等。风电轴承废油脂自动清除及集中回收系统与集中
