EXAMPLE five
In one embodiment of the present invention, as shown in FIG. 4, a water pump 110 in the steam assembly 100 is used to pump water from the liquid supply tank into the steam generator 102 and the water tank 104; the water level probe is used to detect the water level in the water tank 104 (i.e., the liquid level in the water tank 104 referred to in this application); according to the principle of a communicating vessel, the water level in the water tank 104 reflects the true water level in the steam generator 102 (i.e. the liquid level of the steam generator 102 is referred to in this application); under the real working condition, the steam generator 102 is heated, then the water pump 110 in the liquid storage tank 112 is driven into the steam generator 102 and the water tank 104 by the water pump 110, the water level probe monitors the water level in the water tank 104 in real time, and the water pump 110 is controlled, so that the water level in the water tank 104 is kept at a proper height (namely the first height value referred to in the application), preferably kept at about 50%, and the situation that the water is sprayed out of the steam generator 102 due to excessive water pumping in the working process is avoided.
Also, based on the above-mentioned steam assembly 100, it can be used to monitor whether there is a water shortage in the liquid storage tank 112, and specifically, if the water level in the water tank 104 drops all the time when the water pump 110 is running, it can be determined that there is a water shortage in the liquid storage tank 112 at this time, and a water shortage warning is issued.
Also, based on the above-mentioned steam assembly 100, it can be used to monitor whether the steam generator 102 has more scale, and specifically, it is theoretically calculated that the water pump 110 with a certain rotation speed pumps water to make the water level of the steam generator 102 without scale reach point E, which is reflected by the water tank 104. However, when the steam generator 102 with a relatively large amount of scale is used to pump water at the same rotation speed, the water level of the water tank 104 reaches a point C (not shown), wherein the point C is higher than the point E, and it can be determined that the scale in the steam generator 102 has reached a relatively large amount, and a scale cleaning alarm is required.
