The error of the fuel dispenser exceeds ±0.30 percent , and the reasons for not being able to adjust are as follows:
1. Lub flowmeter txuas thaiv yog hnav. Thaum lub bore txoj kab uas hla ntawm qhov txuas txuas ntxiv, cov hlab ntsha ntawm lub piston nce, qhov tso tawm ntim nce, thiab cov roj them nyiaj kuj yuav nce ntxiv.
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. Lub piston lub tog raj kheej liner ntawm cov khoom siv roj dispenser yog hnav. Qhov sib txawv ntawm lub tes tsho tooj liab loj thiab lub piston loj yog hnav tawm, thiab cov roj hauv qhov siab - qhov siab tsis dhau los ntawm cov ntsuas dej ntws rau kev ntsuas cov roj tawm, thiab ntws los ntawm qhov sib txawv, ua rau kev ntsuas qhov yuam kev. .
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. Lub nplhaib sab hauv O- puas lawm. Tom qab ua haujlwm ntev, O- nplhaib yog ib qho yooj yim rau hnav thiab tsis ua haujlwm, ua rau sab hauv thiab ua kom pom qhov yuam kev ntawm kev zam.
Kev daws rau cov khoom siv tanker: hloov lub nplhaib O-.
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.
Kev daws rau cov khoom siv tanker: tshem tawm lub piston, tshem tawm lub cev txawv teb chaws, thiab kho qhov daig; hloov qhov hnyav hnyav kho pas nrig.
