Harmonic Drive servo gear unit FHA-25C-100-E250-C

The air source adopts a water-ring vacuum pump; in the pressure feeding part, the material of the Harmonic Drive canned exhaust equipment servo component FHA-25C-100-E250-C enters the upper sending tank through the pneumatic butterfly valve, and at the same time, the lower sending tank conveys. When the material is conveyed to the lower material level meter, the balance valve opens, the pressures in the upper and lower sending tanks are balanced, the feed butterfly valve opens, the material enters the lower sending tank. After a delay, the butterfly valve closes, the upper tank exhausts and feeds, and the lower sending tank continuously conveys without stopping.

With the development of the market economy, the unloading tasks of bulk materials at the ports along rivers and lakes are very busy. There is a great demand for the bulk cement pneumatic unloader for 1000t ships in the Pearl River Delta, Guangdong. The pneumatic ship unloaders for difficult-to-convey materials such as ores and coal need to be researched, developed and fabricated.

The bulk cement pneumatic unloading machine system in Yueyang Port. It is suitable for unloading bulk cement ships of about 1000t on rivers and lakes. This system consists of two parts. One is to suck from the bulk cement ship to the Harmonic Drive canned exhaust equipment servo component FHA-25C-100-E250-C cement intermediate material tower, and an extendable and rotatable pneumatic unloading machine is adopted. The second is to pressurize and convey from the cement intermediate material tower to the cement silo, and two jet pumps are used for alternate conveying.

Its structure is that the suction nozzle and the material conveying pipe are installed on the hanger. The drooping switch of the suction nozzle and the pitching and rotation of the hanger are all controlled in the operation room, which can realize the suction at different positions. After the cement is separated by the primary cyclone separator, it is discharged by the discharge valve, and the dust-containing air is discharged to the atmosphere through the bag filter. The designed conveying capacity of this device is 100t/h, the conveying horizontal distance is about 10m, the vertical lifting height is about 2m. A three-lobe Roots blower is adopted, and the driving power is 150KW.
