Characteristics of negative pressure conveying system
◎The conveying distance is longer, generally the low-pressure dilute phase can be sent for a distance of 10~300m;
◎The energy consumption of the transmission power source is relatively low (compared with negative pressure and dilute phase);
◎Multi-point feeding and multi-point unloading are possible;
◎After equipped with microelectronic automatic control device, it is easy to realize automation; very reliable, low maintenance system;
◎Sealed without leakage, energy saving, and beautify the environment.
Characteristics of positive pressure conveying system
◎With the most reliable airtightness, the dust in the pipeline will not leak to the environment;
◎The equipment manufacturing and maintenance requirements are low, and the workers are highly maneuverable;
◎The pressure (vacuum degree) used is small and the safety is high;
◎The internal temperature is--up to, especially suitable for heat-sensitive materials;
◎The transportation is continuous or intermittent, and there is no accumulation in the pipeline;
◎Multi-point feeding and multi-point unloading are possible;
◎Using centrifugal fan and Roots blower as gas power source, long service life;
◎Strong adaptability to conveying materials, powder and granular materials can be conveyed smoothly.
