The error of the fuel dispenser exceeds ±0.30 percent , and the reasons for not being able to adjust are as follows:
1. Spojni blok mjerača protoka je istrošen. Kada se promjer provrta priključnog bloka povećava, povećava se hod klipa, povećava se volumen pražnjenja, a također će se povećati i količina plaćenog ulja.
Solution for the fuel dispenser equipment: replace the connecting block or adjust it with the adjusting mechanism. If the hole is not worn much, the original adjustment screw can be lengthened appropriately to increase the adjustment by 0.30 percent .
2. Obloga cilindra klipa opreme za doziranje ulja je istrošena. Razmak između velike bakrene čahure i velikog klipa je istrošen, a ulje u području visokog{1}}tlaka ne prolazi kroz mjerač protoka za mjerenje ispuštanja ulja i curi iz otvora, što rezultira pogreškom u mjerenju .
Tanker Equipment Solution: Return to factory for repair or replacement. If the error value exceeds the allowable error of ±0.3 percent , the wearing parts should be replaced.
3. Unutarnji O-prsten je oštećen. Nakon duljeg rada, O-prsten se lako nosi i pokvari, uzrokujući unutarnje curenje i grešku u indikaciji izvan tolerancije.
Rješenje za opremu tankera: zamijenite O-prsten.
4. The adjustment rod of the fuel dispenser equipment is stuck or worn. That is, there is a foreign body that jams the flow sensor or the adjustment rod is seriously worn, which makes the leakage in the flow measurement converter too large, and even the adjustment value and the leakage amount are very different. For example, broken springs, vanes, screws, gaskets, and other foreign objects on the high-pressure spool in the separator. It is squeezed between the piston and the copper sleeve, or on the top of the piston, so that the piston cannot move and the sensor cannot drain oil.
Rješenje za opremu cisterne: izvadite klip, izvadite strano tijelo i popravite zaglavljeni dio; zamijenite ozbiljno istrošenu šipku za podešavanje.
