instant hot water boiler agent electric hot sell

Fault analysis of instant hot water boiler agent electric hot sell feed pumps and excluded from analysis (1) electric water pump motor to overheat and exclusion for the use of motor-driven feedwater pump is concerned, the most common failure is the motor overheating. Cause overheating of the motor is mainly due to high or low voltage, drive poor ventilation system failure or malfunction caused by overheating of the motor unit. Cause serious overheating of the motor insulation burned, where the occurrence of broken rotor bars and the like. Thus, overheating of the motor should be found in the use of pneumatic power to other ways, for downtime. Motor voltage causes overheating of the motor supply system to deal with checks, to resolve the boiler feed pump motor overheating fault by restoring stable power supply. In addition to poor transmission can also cause motor overheating due to motor and cause motor load is too large to poor transmission between the pump, the phenomenon of a small horse-drawn carts, motor overload is temperature. Such a situation must be timely maintenance, resulting in unit failure. The traditional system of the motor and pump to conduct a thorough investigation, the traditional poor common mainly due to lack of oil transmission system rotating bearing, bearing damage and other causes. Where to find the point of failure can be replaced or lubricated. One of the most common fault caused due to motor overheating when the same subsystem failure, which is mainly due to the damage to the fan, ventilation duct blockage, bearing wear and other reasons that the ventilation system can not complete the work to be undertaken, resulting in motor overheating, serious will burn coil. Such a situation must be by one investigation to find out the cause of the malfunction, unobstructed ventilation duct, fan repair, replacement of bearings can solve the problem. (2) feed pump pump pump overheated boiler feed pump overheated common reason is due to the damage caused by the bearing friction caused by or due to lack of oil lubrication system, oil is not good cause. Thus the pump after the pump was found to overheating should first check the lubrication system is short of oil or lubricating oil containing impurities, followed by investigation bearing damage. For just overheating should also check the rolling bearing of the carriage through the access cover is pump gap is too small. After the inspection the pump shaft still fever should check whether the two-axis bending or misalignment, while checking the balance of the impeller, a two-axis adjusting shaft or concentricity adjustment, remove the impeller balance holes, in order to ensure the rotation of the impeller shaft balance, troubleshooting. The main reason (3) boiler feed pump flow is insufficient boiler feed pump flow rate of the main pump leaves damage, causing pipe blockage or leak. For the use of belt driven water pump also consider whether due to belt slippage caused by the low speed caused by insufficient flow. After checking the investigation belt line, plug the leak at the still insufficient flow impeller should consider whether there is damage. Check the wheel bearings and other parts for lubrication, bearing lubrication to avoid damage caused by poor or lack of speed caused by insufficient flow. 2, boiler feed pump system vibration Trouble boiler feed pump system failure will result in bearing cases inadequate flow, heat pump, dysfunctional and so on, one of the causes of the failure was due to lack of oil lubrication or oil containing impurities cause should on the one hand the unit can also cause an increase in bearing vibration system failure. Pump shock to the system over the General Assembly have an important impact on the security of the entire crew of a serious threat to the security and stability of operation of the unit, and excessive vibration has an important impact on the unit, so the unit basis. In UNITS excessive vibration occurs mainly due to the motor shaft or rotor shaft deformation, damage and bearing mount fixing bolt loosening. After the unit appeared excessive vibration, the bolts should first check whether the firm fixing base, followed by rotation of overheating see whether poor bearing parts, etc. occurs. As the case may be determined over the line of the vibration caused is too large damage to the bearing. After the exclusion of other reasons for vibration still it may be considered to be the motor shaft or rotor shaft deformation caused by excessive vibration. A motor shaft or rotor shaft modification mostly temporary deformation due to the bearing portion causes local deformation unit damage due to overheating. After the shutdown temperature can be balanced deformation can disappear.

Some little knowledge about the daily gas hot water instant hot water boiler agent electric hot sell on the application of the hot water boiler depending on the divided fuel: electric water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; pressure can be divided according to whether pressure hot water boiler and hot water boiler two kinds of pressure, we usually refer to the hot water boiler refers to the pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler . At the same time, it was conducive to a different division of the hot water boiler classification, so that the field of use of hot water boiler is also very extensive. For example, there are heating and 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. Hot water boiler is the production of hot water boilers, heat or other means of thermal energy released by burning the fuel (e.g., electricity, solar energy, etc.) The water was heated to a nominal temperature of a thermal device. The remote can accurately monitor steam boiler combustion process. Degree of automation, all kinds of perfect security. Optional high-quality imported low NOX burner, combustion, are environmentally friendly products. So, these two have for each boiler water production benefits and advantages, will give you specific explain in detail the following: hot water boiler can provide a lot of hot water, wet steam and superheated high-pressure steam, but it can the pressure to achieve only up to 32bar. In today's technical conditions, hot water boiler can achieve temperatures can reach 240 deg.] C, steam flow can reach 45t / h. From the viewpoint of the current epidemic, there is provided the use of wet steam is flash steam boiler ideal solution: hot water boiler provided with wet steam (relative humidity of 2% to 3%) compared to the wet steam boiler to provide steam quickly relative humidity only 0.5%, so that the steam pipe can reduce the harm caused by steam condensation, has a very good thermal conductivity in use. Key to efficient energy-saving steam supply is often associated with the use of steam are closely linked: the occasional use of steam or continuous steam Similarly, if the boiler has a longer downtime, must also consider disabling factor?. Quick steam boiler at startup embodies the advantages of energy-efficient, and can save an average of 5% to 11% of energy; and a hot water boiler in a normal, energy loss is still under continuous operating conditions: heat by radiation and chimney energy loss. And hot water boiler after discontinuation of a long period of time, take a long time to recover back to normal working condition.

What a steam instant hot water boiler agent electric hot sell performance was uneven heat? The following is a non-uniformity reasons: 1, non-uniform heat absorption of the steam boiler. Closely related to the arrangement, operation mode and the type of fuel causes nonuniform heat absorption of the burner. Uneven temperature distribution in the furnace, the heat causes a small load intensity of each furnace waterwall. In general, in the case where the same type of fuel, the heat load distribution in the furnace slagging liquid much larger than the heat load distribution in the furnace slagging solid. Fuel burner heat load is larger than the unevenness of the uneven heat load fired furnace, hot offset vertical tube panel screen than the horizontal tube thermal excursions. DC endothermic steam boiler unevenness different from the natural circulation steam boiler. Natural circulation steam boiler having a heat compensation characteristics, can play a major role in reducing thermal excursions, but the evaporator heating surface in direct steam boiler, heat absorption for larger tube, because the steam generation amount of the inner tube, large capacity . Increase the resistance, the flow rate of the steam pipe is reduced. Conversely, increasing the flow rate of weak heating pipes. Therefore, the DC steam boiler evaporator heating surface will not only cause non-uniform endothermic thermal excursions, but also to expand the non-uniform heat flow by influencing the deviation. 2. The flow rate of the steam boiler is not uniform. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Different resistance to flow parallel to the tubes of the evaporator heating surface, and a change in pressure along the length of the header, and the difference in weight between the head tube and the tube will lead to non-uniform flow. Variation on the thermal flow resistance. Since the structure of the steam pipe, the quality, of different length, diameter, roughness and curvature, the flow resistance is different. Under the same pressure, the flow resistance can cause uneven. When the thermal head 2 in the high-pressure variation in the vertical riser screen, since the height of the larger screen, parallel tubes uneven heating, density vary greatly, it should consider the impact ram repositioning. When high heat load single tubes, the tube bundle of the flow decreases. However, due to the reduced density of the working fluid within the tube and the weight of the head is reduced, the flow rate increases. Accordingly, high pressure water is advantageous to reduce thermal excursions.
