 Material sealed pump drain detailed analysis 
 Henan rich manufacturing materials closure pump hoist, screw conveyor, saving 80-98% of parts and maintenance costs, and has a simple structure, easy maintenance, etc.; material sealed pumps with small size, the wind pressure, reliable operation, almost no wearing parts and many other advantages. Material sealed pump delivery of materials 3-500M, lifting height up to 50M, material sealed pump is a comprehensive, cost-effective professional equipment for conveying powder materials. The seal material pump can be used: thermal power, cement, fly ash, lime, gypsum powder, fine chemical production and use of materials than ≤ 1.6 the following companies. ? 

 Material sealed pump drain Note: 

 : Due to the low-speed bolt slug flow pneumatic conveying system for material sealed pump in the general case, a boiler need to configure two or more pipelines, hence, have is blown counter, dredge the condition of the plumbing fixtures, The closure of the material pump device than to qi ring to clear the conveying pipeline effect, and dredge the speed. 
 : Air is blown butterfly valve, pneumatic counter, ball valves and pipeline pressure switch composed of dredge pipeline installations, the use of a PLC program control set in the pipeline starting end. 
 : When the transmission pipeline pressure switch ultra-high output signal, turn off the L-type sump pumps air intake valve, open the ball valve pneumatic counter, using the negative pressure in the rear of the boiler flue counter, the pipeline dry ash, counter, 30s. At this point, if the transport pipeline pressure is still not down to normal, turn off the counter, pneumatic ball valve, open the pneumatic blowing is a butterfly valve, conveying compressed air to pressurize the pipeline, is blowing time of 90s counter, is blowing a repeated action, until the pressure within the pipeline back to normal, by the transmission pipeline pressure switch output signal, an automatic discharge of dredge pipeline procedures, and pump the normal operation of the program to restore L-type positions. 
 4: transportation system during normal operation, the pneumatic blowing is the butterfly valve, pneumatic counter, ball valve is turned off.
