Powder machine cutting function group
Powder machine cutting function group The first step is to give the powder machine a cutting mode. When set, the following conditions are met: the No. 1 powder feeder is in the working state; the operation stop function group may have an automatic minus No. 1 powder feeder command. Reset, at the same time meet the following conditions to reset: No. 1 to the powder machine closing position and No. 1 primary damper opening position. Operation reset. In the second step, the No. 1 powder feeder cut-off mode opens the No. 1 powder feeder. The No. 1 powder feeding machine cut mode reset cut-off function group is completed. Automatic addition and subtraction to the powder machine automatic addition and subtraction to the powder machine is the control system to automatically monitor the unit parameters, automatically enter the powder machine or automatically cut off the powder machine when the conditions are met, the logic of the A and B sides is the same, the following is a case of the side A This feature. The A side automatic feeding machine simultaneously satisfies the following conditions to give the A side automatic adding powder machine command: the A side fuel is in the automatic position; the A side fuel frequency control output is >85%; the AGC given unit load > The unit current load 20MW; The AGC given unit load is between 190,320 MW. A side of the powder machine automatically add spare. Set, at the same time meet the following conditions to operate the setting No. 1 to the powder machine automatically add spare: No. 1 to the powder machine is not closed; No. 1 powder machine is not in the inspection position; A side no powder machine is automatically added standby. Reset, at the same time meet the following conditions: Operation No. 1 to the powder machine automatically add resettable automatic plus standby: No. 1 powder feeder is automatically added standby; No. 1 powder feeder is not closed; No. 1 powder feeder is not in the inspection position. In addition, the No. 1 powder feeder can be reset and automatically reset when it is switched to the closing position. Meet the following conditions to give the No. 1 powder machine automatic addition command, start No. 1 to the powder machine start function group: A side powder machine automatically add switch in the allowed position; A side powder machine automatically add command; No. 1 powder machine Automatically add an alternate location. The A side automatic reduction powder feeder meets the following conditions to give the A side automatic reduction powder feeder command: The outer surface temperature rise of the Power Cable The heat generation spectrum refers to the temperature of the cable along the length L of the cable surface under a certain load condition. The T distribution condition can be expressed as T=f(L) by a function. The above simulations were carried out in the laboratory at room temperature of 28e. For outdoor and other temperatures, no further discussion is required and further research is required to obtain more adequate data. 400series Petroleum Submersed Pump
Centrifugal pump is an important part of electric submersible pump. In recent years, the technology of electric submersible pump lifting is developing rapidly at home and abroad. In oil field production, especially in high water cut stage, most of the crude oil is produced by electric submersible pump. The electric submersible pump plays an important role in lifting technology of non flowing wells and wells with high yield in.
