一、生产流程简介原油车间是石油生产的第一环。泵房主要任务是用电泵把油罐车油罐中的原油依重力流入到中间罐的原油送到原油大罐去,以备下道工序用。这就要求:1.中间罐的油面高于某个数值时,开动机泵,如果开动一组机泵不行,可再开动一组,以防原油流出中间罐。反之,中间罐的油面低于某个数值时,则应停止电泵,以防抽空。2.油泵开动时,出口阀门不能立刻打开(否则会损伤大轴),当油泵出口油压大于一定值时再打开阀门。3.油泵停止时,出口阀门应立刻关闭(否则大罐中的原油会回流)。
First, the production process profile Crude oil workshop is the first ring of oil production. The main task of the pump room is to pump the crude oil in the oil tanker truck into the middle tank by gravitation according to gravity and then send it to the crude oil tank for preparation for the next procedure. This requires: 1 middle tank oil level is higher than a certain value, start the pump, if the start of a group of pump does not work, you can open a group to prevent the crude oil out of the middle tank. Conversely, when the tank oil level below a certain value, you should stop the pump to prevent taking the time. 2. When the pump is started, the outlet valve can not be opened immediately (otherwise the shaft will be damaged). When the hydraulic pressure at the outlet of the oil pump is higher than a certain value, the valve will be opened again. 3. When the pump is stopped, the outlet valve should be closed immediately (otherwise the oil in the large tank will reflow).
