In this embodiment, a liquid level sensor is disposed in each of the liquid storage tanks 111; the liquid level sensor detects liquid level data of the pigment solution in the liquid storage tank 111.
In this embodiment, the water outlet of each liquid storage tank 111 is provided with a corresponding valve, so that two liquid storage tanks 111 can alternately convey pigment solution, and two liquid storage tanks 111 can also convey pigment solution simultaneously, so that the liquid supply device 2 is guaranteed to have enough pigment solution supply, and meanwhile, each liquid storage tank 111 is provided with a liquid level sensor, so that pigment solution can be supplemented to the corresponding liquid storage tank 111 in time through the liquid supplementing tank 12.
In this embodiment, the feed liquid supply device 2 includes: at least two feed liquid supply pipes 21 and at least two feed liquid booster pumps; each feed liquid supply pipeline 21 is connected with a corresponding liquid storage tank 111 and a filtering device 5, and each feed liquid booster pump is arranged in the corresponding feed liquid supply pipeline 21; the feed liquid supply pipe 21 receives the pigment solution discharged from the liquid storage tank 111 to make the feed liquid booster pump boost the pigment solution toward the filtering device 5.
The fluid is thrown out from the center of the impeller under the action of centrifugal force when the impeller rotates, and a low pressure area is formed at the center of the impeller due to the throwing out of a large amount of fluid, so that a pressure difference is formed between the pump suction port and the center of the impeller, and the fluid is sucked into the impeller under the action of the pressure difference. In a sense, this pressure differential is a prerequisite for fluid to be sucked into the impeller, i.e. the power source, and the greater the pressure differential between the center of the impeller and the pump intake, the more easily fluid is sucked into the impeller, within a certain pressure differential range. However, the liquid form is transformed with temperature and pressure differences, for example: the water is vaporized at a temperature of 20℃and a pressure of 2.4X103 Pa. In general, the lower the pressure, the easier the liquid is to vaporize when the temperature is set; when the pressure is constant, the higher the temperature, the easier the liquid is to vaporize. Therefore, during operation of the centrifugal pump, if the pressure at the center of the impeller is lower than the vaporization pressure of the liquid at the delivery temperature, vaporization of the liquid occurs. The vaporization degree of the liquid is related to the pressure and the temperature. Cavitation occurs when the internal pressure of a liquid drops below the saturation vapor pressure of the liquid at that temperature. Cavitation is caused by the phenomena of increasing the saturated vapor pressure of liquid such as suction inlet pressure, suction height, suction inlet line resistance, viscosity of the conveying liquid, and temperature of the sucking liquid, and the like, and pigment solution is poured into the liquid supply device 2 by arranging the pigment storage device 1 at the high position of the liquid supply device 2, and the centrifugal force of the booster pump and the pressure of the poured pigment solution reach balance, so that cavitation can be avoided, and the effect of protecting the liquid booster pump is achieved.
