automatic oil or gas hot water boiler
Electric steam boiler of the heating process due to elevated water temperature within electric steam boiler, heating and evaporation of the bubble surface of the metal wall temperature begins to rise at any time. There are heating and automatic oil or hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Since the bubble greater wall thickness, in the electric boiler of the heating process, the thermal stress is a major problem, it is necessary for the thermal expansion of the bubble temperature and thermal stress study. At the same time, also considering the overall thermal expansion problems, especially an electrical heating surface tube steam boiler, since the thin wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused. In the process of generating steam and processing the thermoelectric pressure steam boiler, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall at a temperature above the wall temperature, the wall thickness and the temperature difference between the upper and lower walls of the bubble there is a temperature difference, i.e., bubble the inner wall temperature above the temperature of the outer wall, the wall temperature is higher than the wall temperature, the temperature difference between the thickness of the bubble exists in the thickness direction, the upper and lower walls of the larger temperature difference between the bubble, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the wall temperature. In order to prevent excessive thermal stress, it is necessary to gradually increase the pressure of the boiler. In the process of electric spark and boost steam boiler, the steam parameters of the boiler components, water and conditions are changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange a variety of instruments to monitor closely the instruction of professional change. Within the normal allowable range, but also the reliability and safety of various instruments, valves and other components was evaluated by adjusting the process parameters pressure, temperature, water, etc., in order to fully guarantee the security of the electric steam boiler stable operation. The higher the electric steam boiler pressure, the higher the energy, the corresponding steam plant, pipes and valves can withstand the pressure will increase, which also makes the maintenance and protection requirements of the steam boiler is relatively high. In the production and transportation, and the ratio of heat loss will increase the share of the steam.
When we use the boiler, it is unavoidable to have faults or abnormal phenomena, but in order not to affect the normal use, when the boiler appears problems should be dealt with in a timely manner, then in the face of all kinds of circumstances, how should we deal with it? Share with you some ways to handle exceptions. If only the boiler circulating pump abnormal, such as its current reduced, outlet pump pressure return to zero, which means that the pump is idling non-oil, may be caused by vaporization of oil. Therefore, first of all, Yang should take measures to identify the cause of vaporization; if the filter blockage causes the circulating pump to empty, the by-pass cleaning filter should be opened immediately; such as the new heat transfer fluid containing water or Water-decomposing gas is not excluded in the system, then the open valve should be opened immediately. If the circulating pump pressure is constant, the current increases and the flow rate decreases, the heat transfer fluid is metamorphic and the viscosity is increased, so it should be replaced or regenerated in time. If the gas containing water or decomposing is not excluded from the system due to the new heat conduction fluid, the gas should be discharged immediately by opening the valve. When the current of the circulating pump is lower than the normal value, it shows that the efficiency of the circulating pump is lower and the flow rate is decreased, which may be the fouling blockage of the heating pipeline, and the stainless steel chain should be cleaned. If the pressure difference between the front and back of the filter in the boiler increases and the pressure of the pump inlet drops, the filter may be blocked. The bypass should be opened and the filter should be turned on. Remove cleaning. In addition, the low outlet temperature of the liquid-phase heat carrier furnace and the lack of heat supply are mainly due to the problem of ash accumulation, so soot-blowing should be carried out in time. A more common problem with the boiler's grate is that it is stuck because it is broken or loose after the pin has fallen off; metal inclusions in the coal trap the grate; the grate is arched; and the tip of the slag stopper sinks to jam the grate. In view of this phenomenon, it is necessary to clean up the debris with the plate hand-down converter row, replace the broken furnace platoon and start again, if it is stuck again after the start-up, then check the causes after stopping the rotation and solve the problem in detail. At the same time, it is necessary to adjust the screws on both sides and tighten the grate, if it is still not correct. Often, you need to change the sprocket.
Fuel gas-fired boiler has been widely used in the country as an alternative to high gas boiler pollution, fuel gas-fired boiler has been widely used across the country. The use of gas gas boiler promotes people's lives. To prolong the life of the boiler, it must be maintained. One might ask, how should the boiler maintenance? First, the main components of the gas boiler: a burner: Burner collector, equipment, oil and gas as a whole. The highly integrated and highly automated boiler system to maintain focus. 2, the boiler body: the boiler is to achieve the main body of the thermal energy conversion member 3, computer control system: the computer control system is the core component of the boiler, the boiler is the command center. Second, to maintain each of the system 1, the burner maintenance: a rotor cup thoroughly clean the burner, ignition means, filter, pump, motor and impeller systems, and adding a lubricant on the damper linkage. Retest combustion. 2, the controller maintenance: inspection and inspection of electrical elements, control lines, purge control ash box, each control point is detected. , Sealing process. Controller assembly prevents wetting. 3, the water supply system maintenance: repair water treatment plant to check whether water quality standards, a comprehensive clean water treatment system, check into the operation of pumps and elevators, check whether the valve of each tube can be used flexibly. Cutting water, the system is filled with water, the valve is closed. 4, oven maintenance: In order to make long-term safe operation of boilers, boiler maintenance must strengthen everyday use. This is also an important measure thermal efficiency and avoid the deterioration of the state of deterioration of the boiler and prevent accidents.
Customer Service Manager to show the party fast self-developed cloud services 3.0 system, customer management, manufacturing orders, tracking shipments, commissioning monitoring, data analysis, development of online features such as warranty, the boiler has become a "butler." For the convenience of the user to monitor operation of the boiler, combine mobile phone user habits, to invest in developing mobile client APP, to achieve fault repair, maintenance reminders, data entry, work order tracking and other functions, allowing users real-time dynamic control of the boiler.
