With this knowledge points, easily handle common fault boiler pump gas boiler pump is an important equipment, mainly for replenishment aspects boiler. Once the water pump fails, will first trigger replenishment system abnormalities, then water level gauge, pressure gauge, valve instrument will throughout the spate of error, and thus lead to serious boiler accidents. We have compiled the boiler pump five common faults; mastered them, to help you easily cope with pump failure. A lack of flow causes: Effect of multiple pump flow is insufficient suction pipe leakage, valve leakage bottom; inlet plug; insufficient depth of the bottom valve into the water; the water pump speed is too low; sealing ring or excessive wear of the impeller; and other highly absorbent excessive . Solution: Check the suction pipe with the bottom valve, blocking the leakage source; clean mud inlet at the outlet or plug; end of the valve must be greater than the depth of the water inlet pipe 1.5 times the diameter, to increase the depth of the bottom valve into water; check the power supply voltage, increase pump speed, replace the seal ring or impeller; reduce the installation position of the pump, or the replacement of the high lift pump. Second, causes excessive power consumption: pump speed is too high; the pump shaft bending or misalignment of the spindle motor or pump shaft and not parallel; inappropriate selection of the pump head; pump suction sediment or obstructions; motor ball bearing damage. Processing Method: check circuit voltage, reducing the pump speed; correct or adjust the relative position of the pump shaft and the pump motor; with a suitable pump head; or clean sediment blockage; three ball bearings replace the motor, pump noise or rattling Cause: pump installation is not strong or high pump installation; motor ball bearing damage; pump shaft and the motor shaft bending or misalignment, and the like are not parallel. Approach: install stable pumps or pump with reduced height; replace motor ball; correction bent pump shaft or adjust the relative position of the pump and motor. Fourth, the motor shaft, or bearing overheating causes: lack of lubrication or bearing rupture. Approach: filling oil or replacement. V. No water causes: pump and suction tube not filled with water; level below the pump filter tube; suction tube rupture. Processing Method: negative end of valve failure, filled with water; reduce the installation position of the pump, so that water drainage pipe under the action, or the like movable liter water filter and then pumping water; the suction pipe repair or replacement

Hot water boiler belongs to special equipment, and is also a kind of high temperature and high pressure thermal energy equipment. It is inevitable that some faults will occur in the process of operation, which are normal, but it is very likely that the explosion of cost of high efficiency hot water boiler will occur if it is not properly dealt with. Therefore, for equipment safety and personal safety, we must understand some prevention hot water boiler explosion common sense. In the design of hot water boiler, thermal calculation and strength calculation should be carried out strictly according to the requirement, the structure layout should be reasonable, and the material selection should be qualified. In order to ensure the boiler quality conforms to the drawing, the boiler should be constructed according to the drawing. The degree of delimitation. Boiler safety accessories should be complete, agile and reliable, and on-time maintenance, frequent inspection, failure of accessories should be replaced in a timely manner. Repair and repair the boiler inside and outside the boiler according to the schedule, repair and reform the existing problems in time to ensure the quality of inspection. 2. Fuel oil and gas-fired hot water boiler explosion accident in furnace to prevent explosion of hot water boiler should be carefully checked before the point of the hot water boiler, whether the oil path is tight (leakage), the pressure is normal or not, and the newly installed and modified oil and gas pipelines must be blown clean. Check whether the blower has been ventilated for 5 minutes before ignition, and analyze the reasons after ignition failure, and then follow the ignition procedure to penetrate the air. Ignite. For boilers that have not been certified for boiler use and annual inspection, the grater has the right to refuse to light the furnace. The enterprise should lay down the experienced stoves who have rich experience in the operation of the furnace. The staff of the furnace should step up the tour inspection, deal with the problems in time, prevent the flameout, and stop the fuel as soon as it is found out. The boiler shall be equipped with automatic protection devices, including automatic ignition, flameout protection, automatic combustion regulation and necessary interlocking alarm protection devices.

Gas cost of high efficiency hot water boiler introduce Henan fast boiler gas hot water boiler description: 2t gas hot water boiler central heating of the ground a large, large output, load potential, thermal value of around 95%. The diameter of the furnace to ensure the geography based sauce any ignition furnace space, is not easy to accumulate dust, smoke tube, save ignited. The total area of ​​the small furnace, automatic. Gas hot water boiler operating costs lower than electric heating boiler. Low-cost operation, the application of the tertiary industry increased costs, all wet back furnace construction, pipe and plate does not ignite the situation. The present invention improves radiation heat transfer heating furnace of the ground and heat value. Use period of 20 years. Automatically adjust the heating temperature, heating time can be flexible manipulation. The temperature of each room can be adjusted. Sewage treatment rate in the furnace control up and down 8%, a reasonable reduction in the value of, oil and gas boilers and other auxiliary facilities than small biomass boilers, have little energy, high speed continuous operation, low energy consumption, low cost and other advantages.

January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.

Prior to 2017, the total removal of Harbin urban built-up area of ​​small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.

According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.
