Fault analysis of 220v electric water dispenser boiler 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.

Why should the petroleum industry use steam 220v electric water dispenser boilers

It is well known that the petroleum and petrochemical industry is inseparable from the use of large-scale steam boilers for thermal energy conversion or filtration use. The reason why steam-type boilers will be selected for processing use. Because not only high thermal energy but also energy-saving and environmental protection can meet the needs of petroleum and petrochemical industry. Professional steam boiler can not only help the petrochemical industry to process smoothly, but also help enterprises to produce huge economic benefits to improve the production of petroleum processing. Let's follow the editor to see why steam boilers are used in the oil industry:

1, it can save processing costs more effectively because steam boilers can save energy and environmental protection in the process of processing and use to reduce power consumption, so the use of the corresponding in the petroleum and petrochemical industry can reduce the larger cost investment. Moreover, steam boilers use electric energy to process and use, so they can effectively save a lot of energy consumption and help enterprises reduce costs. Reducing the cost can be more beneficial to the petrochemical industry to use a large number of processing to improve economic efficiency.

2, the reason why steam boilers are selected for long-term processing and use in the oil industry with high safety and stability of steam pressure is also because steam boilers are stable in operation and can carry out effective range control. Moreover, the boiler can control itself in the safe operation of steam pressure value, and ensure the safety and stability of the equipment in the process of operation. Therefore, it is especially suitable for petroleum and petrochemical industry with large processing capacity and long duration.

3, boiler energy-saving technology highlights that petroleum needs the conversion of boiler thermal energy in the refining and chemical process to carry out normally, and steam boiler has unique energy-saving technology and can automatically feed water through frequency conversion technology. Moreover, the steam temperature and pressure can be automatically adjusted under stable conditions, so it can be more energy-saving and stable compared with the continuous working process, and it can also save energy and reduce emissions while ensuring the normal supply of petroleum processing at the same time.

At the same time, the pressure of gas 220v electric water dispenser boiler also provides all aspects of daily life a great convenience and saves a lot of resources, with a high economic efficiency. The potential for sustainable development in the market is very large, demand showed a growing trend. Then, when the user selected pressure boiler, what is good? 1, with the gradual development of cost-effective, "West-East" project, making natural gas prices continue to decrease, so that the knock-on effect of fuel costs began to decrease. In addition, because of the high cost of high-pressure gas boiler efficiency can be improved boiler combustion efficiency and save a lot of fuel. Boiler and extremely durable, maintenance costs are not high. Then reduce the cost of buying fuel, fuel also saves overall consumption costs of boiler pressure will be reduced. 2, high efficiency due to the pressure of the gas boiler flue gas three return flow arrangement, wet-back structure greatly increases the area of ​​the heating boiler; tail flue recovery is also arranged flue gas condensation, the flue gas absorbing latent heat utilization portion again, both to reduce the flue gas temperature, but also improve the thermal efficiency of the boiler. Advanced automatic burner using a continuous frequency electric adjustment, so that a particularly high efficiency of the boiler combustion pressure. 3, safe and stable after pressure boiler professionally designed with ultra-gentle overpressure, water and leak detection, and flame protection and other functions. These protections are making very safe and reliable boiler operation. 4, space-saving gas pressure boiler uses quick structure, with strong base boiler steel. This design structure easier to install and transport, greatly reducing the space pressure boiler footprint, and save a lot of space.
