In summary, the system works as follows:
firstly, pumping water and steam for operation:
a) after the system is powered on, when the vacuum pump 1 runs, the oil filter pump 7 starts to run, oil in the vacuum pump 1 sequentially passes through the oil cold discharge system 2 and the oil filter module 3 through pipelines and then returns to the vacuum pump 1 through pipelines, and water filtered by the system enters the water storage device 5 through the water return pipeline and the electromagnetic valve 4 from the water storage cup in the separation filter element module 9.
b) The specific control command is as follows:
after the system operates for a period of time, the oil temperature of the second oil path inlet 12 of the oil filter pump 7 gradually increases, when the oil temperature of the second oil path inlet 12 of the oil filter pump 7 is higher than the set temperature, the oil cooling system 2 is started, and the oil cooling system 2 is closed after the oil temperature is reduced to the set temperature; in the process, the oil flows specifically as follows: the first oil path inlet 10 → the pre-coarse filter module 6 → the second oil path inlet 12 → the oil filter pump 7 → the second oil path outlet 15 → the third oil path inlet 16 → the coalescing filter for removing impurities 8 → the third oil path outlet 17 → the fourth oil path inlet 19 → the separating cartridge module 9 → the fourth oil path outlet 18 → the vacuum pump 1. When the oil level of the vacuum pump 1 is higher than the set high liquid level, the electromagnetic valve 4 is opened, and when the oil level is lower than or equal to the set low liquid level, the electromagnetic valve 4 is closed.
Secondly, acid and alkali gas pumping operation: the specific operation mode and the oil loop system are consistent with the pumping steam. Here, it should be emphasized that: and if the vacuum pump 1 continuously works according to the set corresponding working parameters (including time, liquid level and the like), starting the oil filter pump 7 to work according to the set corresponding working parameters (including time and the like).
Thirdly, self-cleaning operation:
the system may be operated in a self-cleaning mode when it is operated for a period of time. Starting an oil filter pump 7 after the vacuum pump 1 operates the set working parameters; the oil filter pump 7 turns off the vacuum pump 1 after starting the set working parameters; after the vacuum pump 1 stops, the oil filter pump 7 stops after running the set working parameters again; the other operation conditions are consistent with the pumping steam operation conditions.
Fourthly, manually controlling operation:
the full-automatic control system for impurity removal and water removal of oil in the whole rotary vane vacuum pump 1 can be operated by manual control, and the specific operation is as follows: the vacuum pump 1 is started independently, the oil filter pump 7 can be started, the operating liquid level of the system is observed after the oil filter pump 7 is started, and water can be discharged manually when the liquid level does not reach the operating standard (the specific liquid level parameters are consistent with the operation modes).
The above operation modes do not represent all the operation modes of the scheme, and a user can finely adjust the system according to the needs of the industry to realize different functions.
In conclusion, the oil impurity removal and water removal full-automatic control system of the vacuum pump 1 provided by the invention can be operated fully automatically, unattended operation is realized, and impurities and water absorbed into a pump body are effectively removed by the rotary-vane vacuum pump 1 system on the basis of the traditional technology.
