本实施例中，润滑调节油站的工作原理：油站辅油泵开启后，油箱内的油经过油箱出口，出油阀门及粗过滤器，再经过油泵将油输出。输出的油经过冷却器进行冷却后再经油过滤器进行过滤，过滤后的油分两路，一路给汽轮机进行调节供油，另一路经过调压阀降低油压，对汽轮机及离心压缩机进行润滑供油。然后开启汽轮机，带动主油泵工作，经过上述管路给自身及压缩机润滑供油。等主机工作正常后，辅油泵停机转为备用。In this embodiment, the working principle of the lubrication regulating oil station: after the auxiliary oil pump of the oil station is turned on, the oil in the oil tank passes through the outlet of the oil tank, the oil outlet valve and the coarse filter, and then the oil is output through the oil pump. The output oil is cooled by the cooler and then filtered by the oil filter. The filtered oil is divided into two routes, one for regulating the oil supply to the steam turbine, and the other for lubricating the steam turbine and the centrifugal compressor through the pressure regulating valve to reduce the oil pressure. Fuel. Then turn on the steam turbine, drive the main oil pump to work, lubricate and supply oil to itself and the compressor through the above-mentioned pipeline. After the main engine works normally, the auxiliary oil pump stops and becomes standby.
本实施例中，主油泵采用汽轮机驱动泵的优点如下：1、在全厂停电后，设备惰走时能够润滑；2、省电；3、当控制系统出问题的时候，不会出现外用油泵停止运行而压缩机运行。上述油站上的只有一台辅油泵，冷却器，过滤器均采用互为备用设计，一个正常使用时另一个作为备用，以防止以上部件故障时整台设备停机。In this embodiment, the main oil pump adopts the steam turbine to drive the pump. The advantages are as follows: 1. After the power failure of the whole plant, the equipment can be lubricated when it idles; 2. Power saving; 3. When there is a problem with the control system, the external oil pump will not stop running while the compressor is running. There is only one auxiliary oil pump on the above oil station, the cooler and the filter are all designed as spares for each other, and the other is used as a spare when one is in normal use, so as to prevent the whole equipment from shutting down when the above components fail.
油泵出口后的管路中含有球阀一个、止回阀一个。球阀与油箱出口阀门同时关闭后，便可拆卸油泵或泵吸入过滤器进行维修及清洗。止回阀的作用是：当油泵关闭后，输出去的油不会倒流。当主油泵开动备用油泵关闭时，主油泵输出的油不会倒流至备用油泵及油箱内。反之，也是如此。The pipeline after the outlet of the oil pump contains a ball valve and a check valve. After the ball valve and the oil tank outlet valve are closed at the same time, the oil pump or pump suction filter can be disassembled for maintenance and cleaning. The function of the check valve is: when the oil pump is closed, the output oil will not flow back. When the main oil pump is turned on and the standby oil pump is turned off, the oil output by the main oil pump will not flow back into the standby oil pump and the oil tank. The reverse is also true.
油泵与冷却器相互连接的管路中设置有压力表、温度测量元件，主要是为了测量进入油冷却器前，油泵输出油的压力及温度的，考核是否满足设计值。油冷却器后管路中设置有压力表、温度测量元件、差压变送器，主要是为了测量经过油冷却器后，油的压力损失、油的温度值是否满足设计值。如温度值不满足设计值而进入温度报警值，控制元件将发出报警。油过滤器前后管路上设置的差压变送器，主要是为了测量油经过油过滤器前后的差压是否满足设计值。如不满足设计值，则按设计所设定的不同值(报警值、停机值)，首先报警报，提示操作者将其切换至备用油过滤器。否则差压达到停机值时，机组将联锁自动停机。The pipeline connecting the oil pump and the cooler is equipped with a pressure gauge and a temperature measuring element, mainly to measure the pressure and temperature of the oil output from the oil pump before entering the oil cooler, and check whether it meets the design value. There are pressure gauges, temperature measuring elements, and differential pressure transmitters in the pipeline after the oil cooler, mainly to measure whether the oil pressure loss and oil temperature meet the design value after passing through the oil cooler. If the temperature value does not meet the design value and enters the temperature alarm value, the control element will send out an alarm. The differential pressure transmitter installed on the pipeline before and after the oil filter is mainly to measure whether the differential pressure before and after the oil passes through the oil filter meets the design value. If the design value is not met, according to the different values (alarm value, shutdown value) set by the design, an alarm will be issued first, prompting the operator to switch it to the spare oil filter. Otherwise, when the differential pressure reaches the shutdown value, the unit will be interlocked and automatically shut down.
油泵设计有两组调压阀。第一组设在油泵及冷却器之间，作用是当油泵输出油量大于汽轮机、压缩机所需的调节、润滑油量时将多余的油排回油箱内以及在下一个调压阀前将油压调至汽轮机调节所需的油压。第二组设在调节油供油口之后，作用是将油压调至润滑作业所需的油压值。The oil pump is designed with two sets of pressure regulating valves. The first group is located between the oil pump and the cooler, and its function is to discharge the excess oil back into the oil tank when the output oil volume of the oil pump is greater than the adjustment and lubricating oil volume required by the steam turbine and compressor, and discharge the oil before the next pressure regulating valve. Adjust the pressure to the oil pressure required for turbine regulation. The second group is located after the oil supply port for regulating the oil, and its function is to adjust the oil pressure to the oil pressure value required for the lubrication operation.
蓄能器安装与调节供油口处，用于油泵切换的瞬间补充油量及汽轮机瞬间调节油的补充。The accumulator is installed and adjusted at the oil supply port, which is used for the instant supplementary oil quantity of the oil pump switching and the instant adjustment oil supply of the steam turbine.
高位油箱的作用是当机组停机，油泵关闭时，高位油箱内的油能保证汽轮机、压缩机一定时间内的惰走所需调节、润滑油。油过滤器后管路上还设置一个止回阀，作用是当机组停机，主油泵关闭时，高位油箱流出的油及机组内的存油不会倒流回油站各部件。从而保证了停机时，高位油箱所起的作用。The function of the high-level oil tank is that when the unit is shut down and the oil pump is closed, the oil in the high-level oil tank can ensure the adjustment and lubricating oil required for the steam turbine and compressor to idle within a certain period of time. There is also a check valve installed on the pipeline behind the oil filter. The function is that when the unit is shut down and the main oil pump is closed, the oil flowing out of the high-level oil tank and the oil stored in the unit will not flow back to the components of the oil station. Thus, when the machine is shut down, the function of the high oil tank is ensured.
油雾分离器的作用是使油箱上部由于机组回油所产生的油雾气体排出放空，为了使油雾气体迅速排出放空，油箱上部设有一个带有孔板的充氮气口，利用氮气在油箱内的不断流动及排出，促进油箱内油雾气的排出。The function of the oil mist separator is to discharge and empty the oil mist gas generated by the oil return from the unit on the upper part of the fuel tank. The continuous flow and discharge in the tank promotes the discharge of oil mist in the tank.
本实用新型的保护范围不限于以上实施例及其变换。本领域内技术人员以本实施例的内容为基础进行的常规修改和替换，均属于本实用新型的保护范畴。The protection scope of the present utility model is not limited to the above embodiments and their transformations. Conventional modifications and replacements made by those skilled in the art on the basis of the content of this embodiment all belong to the protection category of the present utility model.
