Detailed Product Description: | With the improvement of the state environmental protection standards and the utilization of fly ash enhanced awareness of the power plant to change the hydraulic ash to dry out the gray has become the current trend. In recent years, dry ash conveying most of the use of sump pumps, but look on the current operation of sump pumps, high pressure, power consumption, high maintenance cost reasons, both environmental pollution and waste of resources, and inconvenience to the storage and transport ash. I plant LFB series development and production of material sealed pump, with the wind down, simple operation, small amount of maintenance and other characteristics, widely used in electric power, cement, chemical and other industries, is the ideal equipment to transport a variety of powdered materials. Second, a single-chamber pump, vacuum conveying fly ash exist 1, power consumption, severe wear and tear 0.4Mpa-0.6Mpa high pressure gas elbow pipe serious wear and tear due to sump pumps. Welding repair worn frequent replacement, especially the valve, inlet valve, exhaust valve wear serious, often stuck with pneumatic three-piece damage the high maintenance costs workers repair climb to the pump on the high temperature environment poor, labor-intensive. 2, the operation is complicated Sump pumps to the material level and timing of automatic control console wiring complexity, a slight problem, involving the electrical, thermal, ash overhaul of the three branches of professionals to the gray market, delays in repair time, to the management a lot of trouble , it is difficult to ensure normal production. 3, the environment, poor For these reasons, to guarantee the operation, repair times, equipment everywhere leakage gray, and threaten the living environment of the factory environment and the people around the great impact to the civilized production. 4, affecting the utilization of fly ash In order to carry out comprehensive utilization of fly ash, companies invested heavily to engage in fly ash production line, but due to frequent damage to the conveyor system can not guarantee winnowing device system to normal production, with gray piping to send not affect the user for gray undermine the corporate image and interests. 5, affecting the normal operation of the sediment pool Design ash points, damage to the sump pumps, water had rushed to the sediment pool, resulting in slag water is not enough, water shortages, due to the ash fineness small, likely to cause network blockage, valves, slurry pump pipe junction masonry scrap, slag system has suffered serious losses. 6, vacuum conveying wear lighter, but the fan a few years later as the wind decreased, resulting in gray to send less than the phenomenon. Three, the superiority of the material sealed pump A small investment in equipment, material sealed pumps can replace two sump pumps, reducing equipment investment. 2, the gas pressure of the feed pump closure for 0.04Mpa-0.1Mpa, reducing the supply pressure, save gas consumption, while reducing the motor power. 3, lower maintenance costs. The system once the installation and commissioning into operation, the basic need to operate, virtually no maintenance, maintenance workers only need to regularly check can. 4, the low pressure transport equipment sealing and reliable operation, plugging phenomenon, environmental outlook has been improved. Fourth, the structure and working principle Material sealed pump is driven by the diffusion chamber, pump, activities, air duct, the executive body parts. Low pressure air inlet pipe, pump, into the diffusion chamber. High-speed air flow through the pump nozzle surrounding material gasification, the nozzle air flow into the diffusion chamber to form a partial vacuum in the nozzle and the diffusion chamber and the gasification material inhaled conveying pipe, the high-speed air flow to enhance the discharge point: Fifth, the use of a single-chamber pump seal material pump cost comparison Transmission length of 350m (50MW unit as an example) Project a single-chamber pump material sealed pump Investment in equipment 200 000 2 × 6.8 million yuan Motor Power 264KW 90KW Annual power consumption Of $ 350,000 121,000 yuan Pressure 0.6Mpa 0.04Mpa Wearing parts and piping costs 130,000 yuan No The operator 6 people 2 people Annual salary 50,000 yuan 20,000 yuan The useful life of 4 years 10 years Dust environment is poor and good Significant energy saving effect 1, the annual cost savings (20m3 air compressor, sump pumps need two seal material pump needs a Roots blower, power 90KW, 80% efficiency of work for 6000 hours, electricity price of 0.28 yuan.) A single-chamber pump annual electricity 2 × 132 × 0.8 × 6000 × 0.28 = 35 million Material sealed pumps annual electricity 1 × 90 × 0.8 × 6000 × 0.28 = 12.1 million A single-chamber pump switch material sealed pump to the annual electricity savings of 229,000 yuan. 2, the running cost savings of 13 +5-2 = 16 million. 3, reduce equipment investment 20 - (6.8 x 2) = 6.4 million These data suggest that: the two materials sealed pump instead of the six sump pumps more than 30 million annual savings, will not only reduce labor intensity, increase economic efficiency, but also to protect the work environment. Six, specifications and model of the main technical parameters Model feed pipe diameter (mm) Transmission capacity (m3 / h) Required air volume (free) (m3/min) Required air pressure (Kpa) Motor power (Kw) Transport equivalent length (m) LFB75 108 1-3 3-9 40-98 3-15 30-500 LFB100 133 3-7 9-20 40-98 15-45 30-500 LFB150 159 7-13 20-36 40-98 45-75 30-500 LFB200 219 13-18 36-50 40-98 75-90 30-500 LFB250 273 18-25 50-70 40-98 90-110 30-500 LFB300 325 25-35 70-98 40-98 110-132 30-500 LFB400 426 35-45 98-130 40-98 132-220 30-500 Seven, the installation operation and maintenance Material sealed pump is usually installed in the end feed warehouse more appropriate to rigid fixation, and air inlet tube to give a fixed While maintaining the duct in a horizontal line, the connection to be sealed to ensure no leakage. Activities of the new production of the pump or changing the delivery of materials, should be the first wind pipe outside the chamber by adding a sufficient amount of lubricating oil, and then through the implementing agencies activities duct be adjusted to change the distance between the nozzle and nozzle, through the debugger choose a more suitable position at the same time a note of the scale scale, began to work properly, stopping when the first nozzle and nozzle closed and the pipe material all the while to stop the wind. The material seal pump only in the material surface with a certain height to work properly, the throughput will be reduced if the material level falls below a certain value. If you suddenly stop gas and other reasons, the pipes get clogged, so that the nozzle with the nozzle closed and blowing until the pipe open. VIII Conclusion The use of high efficiency and low consumption material sealed pump out of a single-chamber pump is the inevitable result of technological development in the thermoelectric industry. Can be expected in the near future this technology will replace the sump pumps and play the leading role in the thermoelectric industry, the level of comprehensive utilization of fly ash to a new height, to create more economic and social benefits. |
