Whether the pneumatic grain suction machine can be successfully used in production, in addition to planning, manufacturing, equipment and operation all aspects must be very careful, maintenance and protection at ordinary times is also very important.In particular, the pneumatic grain conveyor is operating in a sealed state, many faults are not easily detected, which is more important for timely maintenance and maintenance.The pneumatic grain suction machine can be divided into air source machinery, air pipe, feeder, feeding pipe, fork road, separator, unloader, dust pipe, dust removal system and electric control system, etc. We are professional pneumatic conveying manufacturer, now describes the key protection of each part as follows:

1. Maintenance of air duct

The air pipe is the pipe between the air inlet and the air outlet of the fan and the wind cap after the dust catcher of the suction pneumatic grain suction machine.29. Generally speaking, the maintenance of these two parts is not great, but attention must be paid to the sealing of the atmospheric pipe connection and often to whether the atmospheric pipe itself is rusty.The damage of the hood will cause rainwater to enter the tank, also should be repaired in time.The air pipe in the pneumatic grain suction machine includes the inlet from the discharge outlet of the gas compressor to the feeder (or sending tank), together with the intermediate storage tank, gas-water separator, gas supply system and the corresponding distribution pipe.The storage tank and the gas-water separator belong to pressure vessels, and their safety should be checked regularly according to the use requirements of pressure vessels. At the same time, special attention should be paid to the accuracy of the pressure setting of the safety valve.The accumulated oil and water in the gas tank and the gas-water separator should be discharged in time.

2. Maintenance of air source machinery

In compression-type pneumatic grain suction machine, air source machinery mainly refers to air compressor and Roots blower.Because is carries on with the exhaust, therefore to the pressure air machinery itself will not produce the special maintenance problem.Can according to the manufacturer's product specifications in accordance with the requirements of the general machinery repair and maintenance.Water ring vacuum pump and Roots vacuum pump are usually used as air source machinery in suction pneumatic grain suction machine.Because is carries on with inspiratory, once inspiratory contains dirt, can accelerate the wear of fan, affect the performance of fan;There may also be dust adhering to the fan, which will not only reduce the performance of the fan but also produce vibration, seriously affecting the life of the fan.To this end, the fan should be cleaned regularly, get rid of the adhered dust, once found that the fan blade has been worn, it should be replaced in time, to ensure a good operating state.
