1. 在运用气动气体增压泵之前,有必要做以下工作:
1. Before using pneumatic gas booster pump, it is necessary to do the following work:
⑴检查各个管线衔接是否可靠;
(1) Check whether the connection of each pipeline is reliable;
⑵每班检查各个压力显示表是否精确,如果发现误差很大或是指针不动,要及时更换;
(2) Check the accuracy of each pressure indicator in each shift. If it is found that the error is large or the pointer is not moving, it should be replaced in time.
2.敞开增压泵具体步骤如下:
2. The specific steps of the open booster pump are as follows:
⑴ 敞开气体增压泵氮气进口阀门,调节阀门开度巨细,使压力表读数在0.4-0.5MPa之间;
(1) Open the nitrogen inlet valve of the gas booster pump and adjust the opening of the valve so that the pressure gauge reading is between 0.4 and 0.5 MPa;
⑵ 敞开驱动气体阀门(即压缩空气进口阀门),调节调压阀,使压力坚持在0.3-0.5MPa之间,观察氮气出口压力巨细,不能超过反应釜工作压力1.4MPa(气动气体增压泵氮气出口压力不能超过3.0MPa);
(2) Open the driving gas valve (i.e. compressed air inlet valve) and adjust the pressure regulating valve to keep the pressure between 0.3 and 0.5 MPa. Observe the pressure at the outlet of nitrogen, which should not exceed 1.4 MPa of the working pressure of the reactor (the nitrogen outlet pressure of the pneumatic gas booster pump should not exceed 3.0 MPa);

⑶ 敞开氮气减压阀,通常坚持≤1.0MPa即可;接着翻开氯甲烷钢瓶上的氮气阀门(即A阀门),当氮气进入之后,翻开氯甲烷钢瓶的通氯甲烷的阀门(即B阀门),然后翻开C阀门,观察压力表读数,要高于釜内压力;后翻开反应釜的阀门,开端通氯甲烷。
(3) Open the nitrogen pressure relief valve, usually adhere to less than 1.0 MPa; then turn on the nitrogen valve (A valve) on the chloromethane cylinder, when nitrogen enters, turn on the chloromethane valve (B valve) of the chloromethane cylinder, then turn on the C valve, observe the pressure gauge reading, to be higher than the pressure in the kettle; finally turn on the valve of the reactor, open the end of chloromethane.
⑷ 观察钢瓶电子称读数即可,当电子吊称显示读数为480-490Kg之间,则需求换瓶。封闭通氯甲烷的阀门以及氮气进钢瓶的阀门,等到换瓶之后衔接结实,再翻开氮气进钢瓶的阀门,翻开通氯甲烷的钢瓶,直到通到满意工艺要求为止。
(5) It is enough to observe the electronic weighing reading of cylinders. When the display reading of electronic weighing is between 480 and 490 Kg, it is necessary to change the cylinders. Close the valves for chloromethane and nitrogen intake cylinders until they are firmly connected after changing, then open the valves for nitrogen intake cylinders, and open the cylinders for chloromethane until the process requirements are satisfied.
3.通完氯甲烷之后的操作步骤:
3. Operation steps after the completion of chloromethane:
⑴ 封闭釜上通氯甲烷的阀门,接着封闭C阀门,封闭钢瓶上的B阀门;
(1) Close the valve through chloromethane on the kettle, then close the C valve and the B valve on the cylinder;
⑵ 封闭氯甲烷钢瓶上的A阀门,封闭D阀门;
(2) Close A valve and D valve on chloromethane cylinder;
⑶封闭气体增压泵氮气进口阀门,接着封闭空气进口阀门;
(3) Close the nitrogen inlet valve of the gas booster pump, and then close the air inlet valve.
⑷至此一个循环进程完成。
(4) At this point, a circular process is completed.
