For self clean system, its design and assembly should meet the following requirement:

Seal reliable the joint of Gas bag, electromagnetism impulse valve and puff blow tube.

Compressed air supply pipeline should set oil gas separator and filter to ensure clean air supplied, while filtered air should eliminate oil, water and residue;

Gas bag bulk should keep electromagnetism stably supply gas, usually 8 or 10 electromagnetism impulse valve as a group.

 

Micro pressure difference sensor and control checking instrument should meet the following requirement:

Range is 0-1500PA(0-150mmH2O)when fully range, its checking precision is 5%
