At present, a conventional water jet vacuum unit is not provided with a matched special control system, and is usually only connected with a power supply of a centrifugal pump matched with the unit to perform on-off operation. However, the water jet vacuum unit also requires control in terms of temperature, liquid level, etc. to ensure performance and long term normal operation. The water temperature in the water tank of the water jet vacuum unit has great influence on the vacuum pumping effect of the vacuum unit, and the higher the temperature is, the lower the vacuum degree the vacuum unit can pump is. The matched buffer tank of the vacuum unit needs to drain liquid regularly, and if the liquid level is too high, water flows to the reaction kettle, so that huge loss can be caused. If the liquid level of a water tank of the water jet vacuum unit is too low, in the running process, gas enters a matched centrifugal pump to cause insufficient pump flow lift and lower vacuum degree. If the liquid level is lower than the inlet of the matched centrifugal pump, the mechanical seal of the centrifugal pump can be overheated and damaged. So that the liquid level needs to be ensured by periodically and automatically adding water. The liquid level and temperature of the water tank and the liquid level in the buffer tank of many water jet vacuum units at present cannot be automatically controlled, which brings inconvenience to the operation of the water jet vacuum units.
