Gong Yifu into a material pump closures - I wait for you in the spring! 
 Gong Yifu into the material sealed pump products, the introduction of foreign advanced technology on the basis of the domestic industry, different types of pneumatic conveying equipment exist various problems to develop a new type of low-pressure pneumatic pump equipment. 
 The material sealed pumps are widely used in thermal power plants, thermal power plant pneumatic ash handling system, water conservancy and hydropower construction sites and city commercial concrete mixing plant, mixing the powder in the station in material handling, cement homogenization and down the library, a variety of powdered materials the delivery, as well as the industries of metallurgy, chemicals, building materials, docks and other powdery material handling, transshipment process. Fu into a series of low-pressure pneumatic conveying equipment, material sealed pump has been successfully used in many powders project is one of the best powdered materials of pneumatic conveying equipment. 

 (1) the principle of selection 
 Selection of low pressure pneumatic conveying equipment, material sealed pump pneumatic conveying systems as the core device, first the user should provide: system requirements for throughput, transmission distance, or physical and chemical parameters of the materials, the highest temperature and normal operating temperature; if the boiler precipitator, it should be provide the basic parameters of the ESP ash bucket arrangement and distribution of ash content. By our factory technicians make sure the transportation of basic programs, such as the required volume, how to group the continuous pump models, the intake and pipeline configuration, library roof collector configuration, and ultimately determine the user review. 
 (2) the applicable conditions 
 The low-pressure pneumatic conveying equipment, material sealed pump, due to the low pressure conveying the scope of use are subject to certain restrictions, only under the following conditions to normal and safe to use and achieve the desired effect. 
 Transmission distance ≯ 500m (equivalent distance). 
 Material bulk density ≯ 2.0t/m3 (powder). 
 The maximum string pump no more than 4 (ie, 4 sets of an input gray tube). 
 Materials of the highest instantaneous temperature ≯ 250 ℃. 
 Concrete mixing plant, batching plant powder delivery system, the use of air compressors for power gas source, the transport distance of ≥ 300m, configuration of specific parameters need to make corresponding changes will be based on site conditions and system processes requests for a separate calculation to determine.
