What are the possible causes of backflow of the HEP500-04 collected fluid into the strainer side?
-
Possible causes of backflow are as follows.
① Foreign matter is clogging the nozzle or diffuser of the liquid collector. Loosen the M3 hexagon socket head set screw located on the side of the body to remove the nozzle, and then remove the foreign matter by air blow, etc. If the wire gauze of the strainer is clogged, remove the C-shaped retaining ring and clean the wire gauze.
② The fluid pressure is less than or equal to 0.02 MPa. The operating fluid pressure range is 0.02 MPa to 0.1 MPa. (However, backflow does not occur even when the operating fluid pressure is 0.5 MPa.)
③ The end of the OUT side tube of the liquid collector is inside the oil. This may result in back pressure being applied, making it difficult for the operating fluid to flow.
④ The pipe length from the strainer to the liquid collector body is 20 m or more when the mounting height of the liquid collector is 3 m or more for a water-soluble solution or 1 m or more for an insoluble solution.
⑤ The dynamic viscosity of the fluid is too high to flow.
⑥ The operating fluid is air. (Air cannot be used as the fluid. While there may be certain situations in which air can be used, liquid cannot be collected reliably.)
