l gear pump Trouble and Maintenance The mainly troubleshooting and failure about pump presents in Table 2-1. Table 2-1 Troubleshooting Serial No. Failure Failure reasons Solutions 1 No delivery or inefficient discharge Exterior elements: Motor stick; motor reversal; Sliding V belt; no oil in tank; pipe jammed; Check motor and its wiring; tighten V belt; inspect tank; dredge pipeline. Gear being stuck Clean waste in pump chamber Waste in outlet of overflow valve Disconnect overflow valve lid and clean waste; Leakage on valve Check oil groove Overweary gear or bearing Replace gears or bearing 2 Large noise or tremble Exterior reasons: Too long horizontal distance between fuel dispenser and tank; many elbow on inlet pipe; waste jam pipe; small diameter of pipe Dealt with in design and construction Intensive pressure Decrease thickness of pressured ring Overflow valve is stuck Clean waste and burr Overweary gear or bearing Replace gears or bearing 3 Inner leakage Overweary gears Replace gears Leakage on frame seal Frame seal disabled Replace frame seal Leakage on pump body or joint face O-ring disabled Substitute seal ring 2.5 Important notices in operation Often inspect the rotation of pump axis, leakage, abnormal noise, vibration on V wheel and lose bolt that tight pump key. Regularly clea fuel dispenser n strainer. The tightness of V wheel should be appropriate, neither too tight nor too loose. These V wheels of motor, pump and adjusting driven wheel should be in parallel level. Don’t adjusting overf fuel dispenser low valve spring too tights in case that result in high pressure of hydraulic system, increase noise and vibration so as to enhance pump abrasion. Prohibit suck water or oil with much water. Strictly abide by the operation requirements on explosive atmosphere. Submersible pump In China filing stations recently begin to adopt submersible pump as the power resource of fuel dispenser. Submersible pump gen fuel dispenser

zerland has legislation enabling people who stay at work for up to five years beyond the statutory retirement age to increase their state pension by up to SFr5,000 ($3,825) a year when they eventually draw it. That helps explain why more than 60% of all 55- to 64-year-old Swiss are in work, compared with less than 30% in Italy and Belgium. (For Italy, which has one of the lowest fertility rates in Europe and one of the lowest average retirement ages, the demographic cliff is a precipice looming at its feet.) In some countries the tax system works against older workers. Britain will not let a taxpayer receive a pension and a salary from the same employer. In America pension schemes will often withhold benefits from a retired person if he is rehired or works for more than 40 hours a month. Companies wishing to hire their pensioners have to find ways round the rules. Japanese companies such as Mazda rehire them on one-year renewable contracts. Staying on Legislation designed to help older workers can act against them. In some ways, America s Age Discrimination in Employment Act discourages the rehiring of retired workers, by requiring that all employees receive equal benefits, such as health-care insurance. That is invariably more expensive for older employees, so it acts as a deterrent to hiring them. Similar legislation is due to come into force in Britain in October this year, fol fuel dispenser lowing an EU directive compelling member states to outlaw discrimination on the grounds of age. Even if the law changes, older workers must still overcome hostile attitudes at work. Many people assum fuel dispenser e that older employees are less motivated, take more sick leave and cost more. The evidence is that many people over 65 have plenty to offer even if they are no longer at their peak (see article). Some studies show that the over-40s are less likely to be off sick, and are more highly motivated and productive (except where great physical effort is required). The best thing managers can do is to make wor fuel dispenser
