Air-cooled Diesel A-type injection pump assembly debugging considerations
F6L912 diesel excavator matching type A fuel injection pump, equipped with RSV governor (mechanical centrifugal speed governor). A-type pump and B-type pump are similar, but the following points need special attention, otherwise easy to cause failure. 1. Fuel pump assembly (1) Plunger and valve assembly and B-type pump is different. Pistons to be demolished, put on a, can not be completely demolished after the installation of new, otherwise it will change the original plunger stroke, resulting in changes in fuel supply. (2) When assembling the plunger, pay attention to align the oil chamber on the plunger with the corresponding oil hole on the plunger sleeve. (3) When installing the pump body, the locking groove on the plunger sleeve should be aligned with the locking screw on the outside of the pump. 2. Fuel supply adjustment A-type injection pump with rack and pinion type oil control mechanism, the amount of fuel supply adjustment method is also slightly different with the B-type pump. (1) minute pump (single) adjustment. No need to open the fuel pump, simply loosen the lock nut, screwing in or out of the adjustment screw to adjust the height of the roller components, thereby changing the pump advance angle. (2) the overall adjustment. Loosen the captive screws of the splitter gear ring, and then rotate the bushing and the plunger relative to the plunger sleeve as needed to adjust the amount of oil supplied to each cylinder at the same time. That is: Loosen the fastening screw and turn the oil control sleeve clockwise to increase the oil volume. Turn the oil control sleeve counterclockwise to reduce the oil volume. (3) test bench adjustment. Fix the oil pump on the test bench first, then connect the oil pipe and the high pressure oil pipe. Turn the flywheel of the test stand, pump up, turn on the power and start the test stand. Then rotate the operating handle to increase the speed when rotating clockwise and to decrease the speed when rotating counterclockwise. Adjust according to the data displayed on the electronic display: When the starting speed (325r / min), the fuel supply is 6mIJ; When the maximum speed (1050r / min), the fuel supply is 5mL; At idle (when the throttle lever is free State), the amount of oil for 1.5 ~ 2mL. If the fuel supply and the specified value does not match, according to sub-pump adjustment method to adjust the sub-pump, until it meets the requirements. Assembly and adjustment is completed, with a clean white cloth and thin wire pump oil pressure valve seat and injector cover. 3. Fuel injector adjustment F6L912 diesel engine injector by the tightening cap, the body, pressure regulating spring, injector body, injector filter, gaskets, back to the oil pipe fittings, oil return plugs, pressure washers, putter , Cylindrical pins, pins and pins and other components, is a 4-hole closed injector. Spray hole diameter of 0.285mm, injection pressure of 17.5-18.3MPa. By adjusting the gasket to change the injector pressure, the pressure is 19.5-20.0 MPa.
