Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] see figure 1 As shown, in the hot water machine fouling simulation experiment device of the present invention, the heat exchange tube 90 to be tested is placed in the constant temperature water tank 80 heated by the heating tube 81, and the configured hard water flows from the hard water tank 30 through the circulating water pump 60. After the temperature measuring probe 70 , the flow meter 91 , the heat exchange tube 90 , it is finally returned to the hard water tank 30 . In order to control the temperature rise of the hard water tank 30 due to the heat exchange cycle, a built-in coil pipe 50 is designed in the hard water tank 30, and a casing is set on the cooling pipeline, and the co...

Abstract

The invention provides a simulation experiment device for scaling of a water heater. The simulation experiment device comprises a hard water tank and a constant-temperature water tank, wherein the hard water tank is connected with heat exchange tubes to be tested through hard water pipelines; and the heat exchange tubes pass through the inside of the constant-temperature water tank. With the adoption of the technical scheme, experimental hard water is injected into the heat exchange tubes to be tested, the constant-temperature water tank is used for simulating a usage environment, and the simulation experiment device for scaling of the water heater can be used for testing scaling conditions of the heat exchange tubes with different shapes under the conditions of different water qualities, different flow rates and different temperatures, so that a theoretical foundation is provided for the design of heat exchange tubes in water systems of commercial water heater units.

Description

technical field [0001] The invention relates to the field of hot water machines, in particular to a scaling simulation experiment device for hot water machines. Background technique [0002] During the use of the water system in the hot water unit, as the temperature in the heat exchange tube increases during the operation of the unit, the water flow velocity changes, and the concentration of various inorganic ions and organic substances, etc., serious deposition will occur in the water system Accumulation of substances and formation of scale, slime, etc., resulting in blockage of the heat exchange system, making the hot water unit unable to produce hot water. [0003] In order to solve the problem of fouling, it is necessary to design a simulation experiment device for fouling of hot water machines, which is used to test the influence of parameters such as different water quality, temperature, flow rate and tube shape on scaling, and to find out different water quality, tem...
