where air being exhausted out and oil being left. When oil level reaching a certain height, oil is controlled by floater and returned low pressure chamber. The inlet and outlet pressure disappear after fuel dispenser stopping work, check valve is closed controlled by spring. Thereby the upper oil of check valve can’t flow into high pressure chamber. Meanwhile, the taper valve on floater plug the hole at check valve seat, check valve also shut down under spring function. Under normal working situation of vapor separator, the oil flowed into separate chamber and returned back low pressure chamber should have an equivalent volume so as to ensure the normal working of vapor separator. If the former oil volume is lower than that of latter, the exhausting pipe would flow out oil. If the oil volume in separate chamber is less than the discharge of check valve, check valve would be opened or closed, so that the accuracy of fuel dispenser will be affected due to pump’s fluctuation. If install check valve, the separate function don’t be affected, reducing flow resistance. If don’t mount check valve , However, returned oil would flow out exhausting pipe after stopping fuel dispenser, and appear cavitation in the down stream of vapor separator and pipeline so that affect next measure accuracy. Therefore, mounting a check valve is necessary to fuel dispenser’s normal operation. Some training books call check valve as outlet valve, but in this manual adapts check valve for facilitating understand. Check valve plays role to release the suddenly high pressure so as to protect hydraulic system. 3. Maintenance and troubleshooting Regularly fuel dispenser cleaning filter is principal sector of maintenance during operation. New filling station always full of dirty and waste in tank and pipeline, thus, the normal operation of fuel dispensers are affected. Thus, paying much attention to check and clean of filter. As the manufacturers made this kind of vapor separator are many, the processing method and product understanding to fuel dispenser fuel dispenser

th blurred and bloody, especially in Baghdad. Ethnic cleansing is proceeding apace. The fact that the two crucial ministries in the new government� defence and interior—have been temporarily handed to acting ministers because of last-minute wrangles bodes ill for the new government s cohesion before it has even begun to function (see article). Meanwhile the American administration, despite its protestations to the contrary, sounds keener than ever to bring its troops home—even though their premature return could speed the onset of a full-scale civil war which would mark down George Bush s Iraqi venture as one of America s greater foreign-policy failures. So the backdrop is bleak. Yet the formation of a new government is still a step forward. And everything must be done—by Iraqis and by outsiders, in the West and in neighbouring Arab and Muslim countries—to give the new prime minister, Nuri al-Maliki, a chance to stem the tide of chaos, to beat back the insurgency, and to give ordinary Iraqis a better life. The odds are against these things happening; but there is a little more hope this week than last. To begin with, Mr Maliki promises to be an improvement on his bumbling predecessor, Ibrahim al-Jaafari. Although hailing from the same Islamist-minded Shia party, the new man has called for tolerance and compromise, says his ministers have been chosen for their competence rather than their religious or ethnic links, and agrees that the militias should be dismantled and their followers absorbed into a new-look national police and army. Even if he has yet to appoint an interior minister, it is still good news that he fuel dispenser had sidelined the previous incumbent, a Shia seen by Sunnis as a sectarian killer. It will be good news, too, if and when a Sunni Arab with genuine support in his own community is named as defence minister, with at least a chance of persuading the more nationalist insurgents, as opposed to the al-Qaeda-minded suicide bombers, that their aims can be achieved by peaceful pol fuel dispenser fuel dispenser
