Energy-saving and high efficiency of gas-fired economy electric hot water boilers best price in are shown in those two aspects its electric system will automatically enter the fully automatic operation state on the one hand: gas-fired boiler after pressing the operation switch. Start safe equipment, gas-fired boiler circuit will be short-circuit, leakage, water shortage, etc. The equipment will automatically alarm and tripping. More safe and efficient! Gas-fired boiler is not the same as coal-fired boiler, on the one hand, gas-fired boiler can be the electronic control system. It is not only more environmentally friendly, energy-saving, currently most used of boilers. Gas-fired boiler electric in the system can achieve automatic operation, as well as safe control. Mainly reflected in two Aspects When a gas-fired boiler is operated on a computer control board, it needs to be replaced with water on time and connected to electricity. When the necessary gas is prepared, any control instructions can be operated through the operation of the electric system, thus eliminating the need for manpower and fuel waste.

Fault analysis of economy electric hot water boilers best price in 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.

The inlet speed of gas-fired hot-water economy electric hot water boilers best price in before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.
