Description

一种空冷电机专用加油管A special fueling pipe for air-cooled motor 技术领域Technical field
本发明涉及加油设备领域,具体涉及一种空冷电机专用加油管。The invention relates to the field of refueling equipment, in particular to a special refueling pipe for an air-cooled motor.
背景技术Background technique
蒸发式空冷器,也叫做闭式冷却塔,是一种将水冷与空冷、传热与传质过程融为一体且兼有两者之长的高效节能冷却设备,广泛应用于冶金、石化、电力、化工等行业。其工作过程为利用循环水泵将循环水水箱中的冷却水输送到位于工艺管束上方的喷水系统,由喷水系统将冷却水向下喷淋到管束表面,在管束表面形成一层薄水膜,与此同时,轴流风机将空气吸入,使空气从管束下方向上横掠倾斜放置的管束,加速空气流动使管束外的薄水膜迅速蒸发,达到管束散热降温的目的。这样的工作过程虽然有效的满足了工艺生产需要,但是对后续轴流风机的维护与保养是非常不利的,出风口和轴流风机安装在整套空冷器的最上方,管束表面的薄水膜迅速汽化后,大量带有热量的水蒸汽由轴流风机排出,这样就使整套轴流风机机组一直暴露在高温蒸汽环境下,作业人员对轴流风机电动机加油保养时,需要将身体探入风机活动半径内,虽然有防护网,但强劲的风力和带有高温的水蒸汽使作业难度非常大且存在巨大的安全风险(在强劲风力作用下,高温水蒸气会影响作业人员的视线甚至会导致呼吸困难)。常规解决方法是停机保养或将加油管路延长,此方法虽然可以实现安全区域内加油的目的,但因为保养周期较长(两极电动机轴承润滑脂一般1440小时加注一次),在潮湿高温环境下,运行中的机组加长管内的润滑脂会液化变质,而备用机组残留在加长管内的润滑脂会凝结成块堵塞加油管,加油保养时无法将变质润滑脂排出,直接加油会将这些变质润滑脂一同加至电机轴承室内,加速了轴承室内油脂的变质,损坏轴承或缩短其使用寿命,严重时则会导致空冷电机损坏影响到装置的正常生产,存在很大的弊端;电动机在运行过程中加注润滑脂才能确保润滑脂的注入均匀,所以停机保养则首先不利于电动机的加油保养,其次停机保养不仅增加了工艺操作,而且不利于生产的稳定,如在高温季节生产装置对降温要求非常高,此时停机维护保养基本无法实施。Evaporative air cooler, also called closed cooling tower, is a high-efficiency energy-saving cooling equipment that integrates water cooling and air cooling, heat and mass transfer processes, and has the advantages of both. It is widely used in metallurgy, petrochemical, and electric power. , Chemical and other industries. Its working process is to use the circulating water pump to transport the cooling water in the circulating water tank to the water spray system located above the process tube bundle, and the water spray system sprays the cooling water down to the surface of the tube bundle, forming a thin water film on the surface of the tube bundle At the same time, the axial flow fan sucks in the air, so that the air sweeps the obliquely placed tube bundle from below the tube bundle, and accelerates the air flow to quickly evaporate the thin water film outside the tube bundle to achieve the purpose of cooling and cooling the tube bundle. Although such a working process effectively meets the needs of process production, it is very unfavorable for the subsequent maintenance and maintenance of the axial flow fan. The air outlet and the axial flow fan are installed at the top of the entire air cooler, and the thin water film on the surface of the tube bundle is rapid. After vaporization, a large amount of water vapor with heat is discharged by the axial flow fan, so that the entire axial flow fan unit is always exposed to the high temperature steam environment. When refueling and maintenance of the axial flow fan motor, the operator needs to explore the body into the fan activity Within the radius, although there is a protective net, the strong wind and high temperature steam make the operation very difficult and there are huge safety risks (under the action of strong wind, the high temperature steam will affect the sight of the operator and even cause breathing difficult). The conventional solution is to shut down for maintenance or extend the refueling pipeline. Although this method can achieve the purpose of refueling in a safe area, because of the long maintenance period (two-pole motor bearing grease is generally refilled once 1440 hours), it is humid and high-temperature environment , The grease in the extension pipe of the running unit will liquefy and deteriorate, while the grease remaining in the extension pipe of the standby unit will condense into blocks and block the refueling pipe. The degraded grease cannot be discharged during refueling and maintenance. Direct refueling will cause these degraded greases. It is added to the motor bearing chamber to accelerate the deterioration of the grease in the bearing chamber, damage the bearing or shorten its service life. In severe cases, it will cause damage to the air-cooled motor and affect the normal production of the device. There are great disadvantages; the motor is added during operation. Grease injection can ensure uniform grease injection. Therefore, shutdown maintenance is firstly not conducive to the refueling and maintenance of the motor. Secondly, shutdown maintenance not only increases the process operation, but also is not conducive to the stability of production. For example, in the high temperature season, the production equipment has very high requirements for cooling At this time, shutdown maintenance is basically impossible to implement.
