Problems solved by technology

[0004] In the above process, when there is a problem with the sealing of the circulation pipeline, the pressure value in the circulation pipeline will drop rapidly, and it is necessary to replenish the heat transfer medium in the circulation pipeline frequently and in large quantities, but it is impossible to remind the staff to check the circulation pipeline. The detection of the road leads to the rapid loss of the supplementary heat transfer medium, resulting in the waste of the heat transfer medium, and the efficiency of the solar heat collection system may be reduced because the liquid cannot be replenished in time

Embodiment 1

[0029] Corresponding to the above-mentioned automatic liquid replenishment equipment, the present invention also provides a maintenance reminder method for automatic liquid replenishment equipment, such as image 3 shown, including:

[0030] Step 300, setting parameter value range

[0031] In the microprocessor 40, a parameter value range is set, and the parameter value includes the fluid rehydration interval, the frequency of rehydration, and the volume of rehydration. The value range of this parameter is set according to the scale of the solar heat collection system and based on experience. For example, the range of rehydration interval is set to be greater than 72 hours, the range of rehydration times is less than 2 times, and the range of rehydration volume is less than 10 liters.

[0032] After setting the range of parameter values, it is necessary to start the automatic replenishment equipment so that it can automatically replenish the heat transfer medium in the circul...

Embodiment 2

[0057] In addition to judging according to the fluid replenishment interval described in Embodiment 1, the working condition of the circulation pipeline 3 can also be judged according to the fluid replenishment amount.

[0058] After the solar heat collection system is in operation, the automatic liquid replenishment equipment is started, and the liquid replenishment volume for one replenishment is obtained according to the flow sensor 2 arranged between the liquid replenishment tank 8 and the circulation pipeline 3, for example, the liquid replenishment volume is 11 liters, which is the same as the set parameter value. Compare the scope of the volume, and determine that the volume of the fluid supplement exceeds the range of the parameter value fluid volume and is less than 10 liters. At this time, the fluid supplement is stopped, and the prompting device 7 is used to remind the staff that the circulation line 3 needs to be overhauled.

Embodiment 3

[0060] In addition to judging based on the rehydration interval described in Embodiment 1 and the amount of rehydration described in Embodiment 2, the working conditions of the circulation pipeline 3 can also be judged by setting the number of times of rehydration within a fixed time interval , for example, set within 72 hours, the range of the number of rehydration times of the parameter value is less than 2 times. At this time, the microprocessor 40 is used to record the number of times that the automatic liquid replenishment equipment replenishes the circulation line 3 within a time interval of 72 hours. 3 performed 3 times of rehydration. At this time, stop the current replenishment, and send a maintenance prompt signal to the prompting device 7 through the microprocessor 40, and the prompting device 7 starts, prompting the staff that the circulating pipeline 3 needs to be overhauled.

Abstract

The invention discloses an automatic liquid replenishment device and a maintenance reminder method for the automatic liquid replenishment device, in order to solve the problem that in the prior art, when a sensor controls the liquid replenishment of a circulation pipeline, the omission of the heat conduction medium in the circulation pipeline cannot be found in time, resulting in the failure of the heat conduction medium It is designed for the waste of waste and the decrease of the efficiency of the solar heat collection system. An automatic liquid replenishing device, comprising: a circulation pipeline and a controller, a solenoid valve is connected to the circulation pipeline, and a liquid replenishment pump is connected to the solenoid valve; the circulation pipeline is connected to a sensor; the controller is connected to the sensor, Solenoid valve, replenishment pump and prompting device are connected.

Description

technical field [0001] The invention relates to a device and a maintenance reminder method, in particular to an automatic fluid replenishment device and a maintenance reminder method for the automatic fluid replenishment device. Background technique [0002] The solar heat collection system has the advantages of safety, environmental protection and energy saving. The solar heat collection system includes a heat collector placed outdoors, the heat collector is connected to a circulation pipeline, and the other end of the circulation pipeline is connected to a heat exchange The inside is filled with heat transfer medium, and the other end of the heat exchanger is connected to the water storage tank. The heat transfer medium heated by solar energy is transferred to the water storage tank through the heat exchanger, and the water in the water storage tank is heated. [0003] In the prior art, in order to prevent the pipe wall of the circulation pipeline from freezing and crackin...
