Diagram 2-7: Installation of framework oil seal Important notices to disassembly and reassembly As pump and motor are the resource of power one should pay much attention to disassembly and reassembly of pump. Be sure that cut power prior to maintenance. Disconnecting V belt in case to cause any accident, prepare a container to collect oil that will pollute environment. Grind the semicircle keyway on pump axis using sand paper before disconnecting pump cover in order not to scratch framework oil-seal by burr. All components should be carefully cleansed prior to reassembly of pump in case dirty substance flow into pump and cause new trouble. Turn rotor and examine the vane working state after in fuel dispenser stalling rotor subassembly and spring in pump chamber. Meanwhile, be sure that the position of vane should higher than rotor, low pump frame even. A little grease should be daubed on the inner of brass bushing and framework oil-seal when installing pump cover. When installing the bolts of pump cover each tension is coh fuel dispenser erent as the sequence that opposite bolts go first. After reassembly of pump to check inspect the rotation of pump. The seal ring between pump and vapor-recovery should be carefully examined before installing in case of leakage. Be sure that the two V wheels of motor and pump in line, having any obvious jump and wave. Internal gear pump Fuel dispenser is mounted now with two types of internal gear pump, namely, involute gear pump and inner cycloidal gear pump. In the former type a piece of crescent clapboard is installed between small gear and inner gear, dividing suction chamber with discharge chamber. However, in the latter type the division is realized through joint between gears, without clapboard. The smaller gear in internal gear pump is driver. Diagram 2-8 illustrate above gear pumps. Internal gear pump characterized that compact, light in weight, low noise and long service life still has disadvantage of complicated gear figure and high cost. Domestic market now has these two kin fuel dispenser

ate Corzine wants his tax increase revenue. His fellow Democrats, who control the Assembly, oppose the increase. When the state legislature missed its budget deadline for the third time in five years, Mr Corzine ordered a government shutdown, a first for New Jersey. According to the state s constitution, without a balanced budget in place the state may not spend money. All non-essential functions of government stopped on July 1st. This means that 45,000 people—over half of all state employees—are on furlough. Only essential personnel such as state police, prison guards and child-welfare workers are still working. Road fuel dispenser works and car inspections have been halted and most courts have been suspended. State parks and beaches, though opened for the July 4th weekend, closed on Wednesday morning. Atlantic City s 12 casinos have also been forced to close. The state s gambling inspectors are considered non-essential employees. They keep t fuel dispenser abs on the collection, counting and certification of winnings. Without them, no dice. The Casino Association of New Jersey looked to the courts to try to remain open, but had no luck. Closure will affect 46,000 workers. Gambling is big money for the Garden State. Many punters question the wisdom of closing casinos, especially as they add $1.3m a day to the state s coffers. Fully 8% of the monthly gross revenues go into the casino revenue fund, which pays for programmes for the elderly and disabled. The lottery, which generates $2m a day in taxes and is the state s fourth-largest tax source, has sold no tickets since Saturday. Horse racing, which also requires monitors, was shut down too. Mr Corzine, anxious to sort out the mess before everyone went back to work on July 5th, ordered lawmakers to labour through the holiday, and slept in his own office on a camp bed. Richard Codey, president of the state Senate and a former governor, has pitched a compromise plan that Mr Corzine f fuel dispenser
