It is generally believed that boilers need maintenance during use. When they are not in use, they still need maintenance. The answer is certain because high-end equipment such as wall-hung boilers, which integrates heating and domestic hot water, is not heated during heating. It is also necessary. The following is the basic method of non-heating maintenance boilers.
First, the system water pressure should always maintain 1.2-1.5 bar. The specific approach is:
1. Open the water inlet switch and close it when the pressure is added to 2 (pressure should not exceed 3);
2, open the last set of radiator drain valve (or floor drain valve), the system will be out of the dirty water;
3, after the "dirty water" flow is clean, close the drain valve, the second time open the water switch pressure to 2 or 3;
4. Repeatedly draining and adding water several times. The first step of rinsing is completed. However, the unloading valve and the inlet valve are opened at the same time until they are thoroughly rinsed.
5. After rinsing, fill with fresh demineralized water and raise the pressure to 1.2.
Second, do not arbitrarily change the dismantling flue, do not hang random debris and clothing on the flue.
Where the gas boiler flue is located, keep the air circulation and the environment clean and tidy. Do not stack the debris at random so as to prevent potential safety hazards.
Third, the use of sanitary hot water, it is best to adjust the temperature in the boiler temperature adjustment at the water point directly open the hot water, do not mix with cold water.
4. In the summer, long-term use of wall-hung boilers will not be used, and the water valves, gas valves, and power supplies connected to the boilers will be closed.
5. After entering the non-heat season, the boiler does not need to drain water.

In the field of mine production, the efficiency, real-time and safety of production and management directly affect the production efficiency and cost control of enterprises. As the main force of mine production, transportation system must also adapt to the requirements of this changing trend. That is to say, the construction, management and dispatching of the whole transportation system should be developed towards informationization, intellectualization, centralization and distributed control – it is imperative to establish a perfect dispatching command center of the transportation system. In view of this, a remote production command and dispatch system, which integrates control, protection and online browsing, emerges as the times require. At present, many modern mines have built such systems, and have achieved substantial direct and indirect benefits.
