    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 installing 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 coherent 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 cresce fuel dispenser nt clapboard fuel dispenser 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

The political establishment is even more firmly behind Israel than the public is. Support for Israel stretches from San Francisco liberals like Nancy Pelosi to southern-fried conservatives like Bill Frist. The House and Senate have both passed bipartisan resolutions condemning Hizbullah and affirming Congress s support for Israel. The House version passed by 410 to 8 (of which three were from districts in Michigan with concentrations of Arab-Americans). The Senate resolution, sponsored by 62 senators? including the leaders of both parties—passed unopposed. Indeed, the parties are engaged in a competition to see who can be the most pro-Israeli. Twenty or so Democrats, including Ms Pelosi, the House leader, and Harry Reid, the Senate leader, demanded that Iraq s prime minister, Nuri al-Maliki, retract his criticisms of Israel or have his invitation to address Congress cancelled. (Mr Maliki, strongly backed by the administration, was eventually allowed to go ahead.) Several leading Democrats, including Hillary Clinton, have addressed pro-Israeli rallies.
