What issues should be paid attention to when purchasing pneumatic grain conveyor?　　

Many people don't know how to buy a suction air conveyor when they buy it, or what they should refer to when buying a grain pneumatic suction machine. Which pneumatic grain conveyor is better? Let me introduce to you the points that need to be paid attention to when purchasing the airslide conveyor 　　

1. Flexibility and output 　　

The flexibility of the pneumatic grain conveyor is closely related to its performance. For example, the pipe is equipped with a multi-purpose hose, which can increase the flexibility of the grain suction machine, and its output and efficiency will inevitably be affected. Otherwise, a certain amount of flexibility will be lost. Both the manufacturer and the user must seek a balance between the two.　　

2.Application range

suction type pneumatic conveyor can not only be used for dock unloading, room-type warehouse outbound, and shallow round warehouse warehousing operations, but also for clearing warehouses, absorbing local heating grains, and cleaning and dusting materials during transportation.　　

3. Performance and cost 　　

The performance of the equipment is closely related to its cost. The better the performance, the higher the cost and the higher the selling price. Manufacturers should reduce costs while ensuring good equipment performance to meet the production needs of different consumers.　　

4. Dust control 　　

The quality of dust control is an important indicator for choosing a grain suction machine. Poor dust control will pollute the environment and endanger the health of the operator. Excessive dust entering the Roots blower will easily cause impeller wear and will directly affect the service life of the blower. Therefore, the high efficiency dust removal filter system is the key.　　

5. Equipment life 　　

Service life is an important factor in investigating the value of equipment. Christensen guarantees that the service life of the main components of its equipment is about 5 years, and domestic products are in the trial production process, and there is no relevant report.　　

6. Food damage 　　

Grain damage is an important indicator of grain grading, and the number of damaged grains directly affects the economic benefits and edible quality of grain storage and transportation.　　

7. Energy consumption 　　

The energy of the pneumatic grain conveyor is derived from electric motors or diesel engines. For users, if the storage area is equipped with high-power cables, electric motors should be used as much as possible; if there are no users with high-power cables, diesel engines can be preferred.　　

8. Fan selection 　　

The fan is a key component of the grain suction air conveyor. The design and selection of the fan directly affect the performance of the grain airslide conveyor. At present, the main selection of fans are vortex fans and Roots fans. The performance of the vortex fan is low wind pressure and high air volume. In the process of grain transportation, the wind speed is high, and the impact force of the grain on the pipe wall is relatively large. The resulting problem is that the increase rate of grain damage is high, and it must be increased. The wall thickness and diameter of the pipe. The performance of Roots blower is high pressure and low air volume. During conveying operation, the wind speed is low, the impact of grains on the pipe wall is small, and the concentration ratio of conveyed grain is high, which reduces the increase rate of grain damage and can also reduce the pipeline The wall thickness and pipe diameter reduce the labor intensity of the operator.　　

Basically noticed these eight points when choosing, then there is no problem with the pneumatic suction machine
