. Examine clearance and replace relevant components when necessary. 1.4. Measurement transducer block 1.5. No discharge due to Solenoid valve closed. First check electric wiring, then trouble on component itself (short circuit of winding or block in valve membrane, etc). 1.6. Pipeline and bottom valve failure If continuously exhaust in vapor separator from beginning, disconnect filter cover and take out filter net; pour same kind of oil in it and given see oil level quickly drop, there is leakage occurred in pipeline and bottom valve. 1.7. No discharge caused by nozzle failure Jam in jointer or filter. Unlock strainer or jointer to remove dirt and waste. Nozzle always in auto-shut state, check automatic shut device, mainly inlet vent, spring. 1.8. Bottom valve be stuck in and pipeline is plugged. Exterior reasons for no delivery Oil level is so lower than bottom valve that pump can’t suck oil. Some valve(s) is closed in pipeline between tank and fuel dispensers. Air goes into valve(s). Single phase valve is rusted in bottom valve. Incorrect installation of flange causes leakage between inlet pipe and fuel dispenser. Inappropriate oil is refueled. Oil is easy to gasify; water in oil freeze; wax in oil plug pipe. Pipe design is unsuitable. Two fuel dispensers, for example, are connected in same pipeline without valve, or valve can’t shut completely; pipeline has many crooks or too thin. Slow flow rate as starting 3.1. Strainers, including cone-shaped filter net and nozzle filter net, are jammed. 3.2. Large amount of air flow into from broken parts or pipeline, causing much foam in oil indicator. 3.3. Large noise and vibration during operation Vacuum pressure is inadequate. Leakage occurs in overflow fuel dispenser valve or pump gasket. Inner leakage in fuel dispenser increase as serious abrasion in pump vane or vane is stuck by waste. Vapor separator trouble Small floater of vapor separator is broken or fall down; insufficient pressure in high pressure chamber as exhausting valve can fuel dispenser fuel dispenser

nies accounts; labour groups and environmental activists are finding new ways to co-ordinate their attacks on business; and big companies such as McDonald s and Wal-Mart have found themselves the targets of scathing films. But those are just the enemies that companies can see. Even more troubling for many managers is dealing with their critics online—because, in the ether, they have little idea who the attackers are. The spread of “social media�across the internet—such as online discussion groups, e-mailing lists and blogs—has brought forth a new breed of brand assassin, who can materialise from nowhere and savage a firm s reputation. Often the assault is warranted; sometimes it is not. But accuracy is not necessarily the issue. One of the main reasons that executives find bloggers so very challenging is because, unlike other “stakeholders� they rarely belong to well-organised groups. That makes them harder to identify, appease and control. When a company is dealing directly with a labour union or an environmental outfit, its top brass often take the easy route, by co-opting the leaders or paying some sort of Danegeld. Until a couple of decades ago, that meant doling out generous union contracts and sticking shareholders, taxpayers or consumers with the bill. More recently, the fashion has been for “corporate social responsibility� This might involve spending money on a pressure group s pet project; or recruiting prominent activists to a joint committee, dedicated to doing good works. In the blogosphere, however, a corporation s next big critic could be anyone. He might be an angry customer or a disgruntled employee—though that sort of tie to the company is not essential; nor does he need lots of industr fuel dispenser y experience or lengthy credentials to be a threat. All a blogger really needs to devastate a company is a bit of information and plausibility, a complaint that catches the imagination and a knack for making others care about his gripe.
