柴油发动机喷油泵的调整
Diesel engine fuel injection pump adjustment
一：最大供油量的调整
A: the maximum supply quantity adjustment
VE型喷油泵的供油量大小是靠控制柱塞泄油孔的行程长度来调节的(俗称断油计量)。油量调整杠杆可绕固定于泵体的支点A转动，而调速杠杆可绕固定于油量调整杠杆上的支点B转动。当需要调整供油量(如标定工况供油量)时，可松开锁紧螺母，将油量调节螺钉旋出(减少供油量)或旋入(增大供油量)。
VE type fuel injection pump oil supply amount is controlled by the plunger oil drain hole stroke length to modulate ( commonly known as oil metering ). Oil volume adjustment lever can rotate around the fixed to the pump body to pivot A rotation, and speed control lever can rotate around the fixed on the oil volume adjustment lever fulcrum B rotation. When need to adjust the amount of oil ( such as rated fuel supply ), locking nut, the oil quantity regulating screw rotation ( reduced oil ) or screwed ( increase fuel delivery ).
二：调速器的调整
Two: Governor setting
在柴油机喷油泵供油量调整完毕后，必须进行调速器的调整，以获得在额定供油量时的额定转速、最高限制转速(“飞车”转速)和最低稳定转速(怠速转速)。
In the diesel engine fuel injection pump oil supply after the adjustment, must undertake the governor adjustment, to get at the rated capacity of the rated speed, maximum speed (" speed" speed ) and the minimum stable speed ( idle speed ).
①最高转速限制螺钉的调整--调速器“飞车”转速试验；首先将调速臂拉到底，使其与高速限制螺钉接触；然后再检查发动机额定转速时的供油量是否符合发动机供油的规定要求。逐步提高油泵转速，使之达到最高限制(断油)转速。此时单缸供油量不大于1ml/200次。如供油量大于规定值，可将高速限制螺钉旋进，即可使供油量减小。
The maximum speed limit screw adjustment - governor" coaster" speed test; the speed regulating arm pull through to the end, with the speed limit screw contact; and then check engine rated speed oil supply meets the requirements of engine oil. Gradually increase the speed of pump, so as to achieve the maximum speed ( oil ). The single cylinder oil supply amount of not more than1ml/200. If the feed quantity is larger than a prescribed value, the speed limit screw is screwed into the oil supply, can be reduced.
②怠速螺钉的调整--怠速试验：将调整臂完全放松，并触及怠速调整螺钉，使喷油泵以250-300r/min的转速运转(按发动机的怠速要求)，其单缸供油量应符合发动机怠速规定。喷油泵在怠速时，如供油量低于规定值，可将怠速螺钉旋进，直到调整合适为止。
②idle screw adjustment - idle speed test: the adjustment arm completely relaxed, and hit the idle adjusting screw, so that the fuel injection pump with250-300r/min speed (according to the engine idle speed requirements ), the single cylinder oil shall be in accordance with the provisions of the engine idling. Fuel injection pump in idle speed, such as the oil supply amount is lower than the prescribed value, the idle screw is screwed into the adjustment, until the appropriate date.
三：喷油正时的调整
Three: injection timing adjustment
柴油机 喷油泵在不同转速时，喷油提前机构的活塞行程应符合规定要求。在检查活塞行程时，可拆下装有弹簧一端的盖板，装上专用测量工具，测量活塞行程。当活塞行程达不到规定值时，可相应地增加或减少垫片厚度进行调整(在弹簧的两端至少应各装一个垫片)。然后再进行喷油正时的调整，装上发动机后，应先进行最佳供油提前角的调整。具体步骤如下：
Diesel engine fuel injection pump in different speed, fuel injection advance mechanism of the piston stroke should be consistent with the requirements. Check piston stroke, with one end of the spring is removable cover plate, mounted on the special measurement tools, measurement of piston stroke. When the piston stroke is not up to the specified value, can increase or decrease the thickness of the gasket is adjusted ( at the two ends of the spring are respectively provided with a gasket shall be at least ). And then the injection timing adjustment, mounted on the engine, priority should be given to the best fuel supply advance angle adjustment. The specific steps are as follows:
①先在喷油泵的传动轴上装传动齿轮，再使油泵内腔充满柴油，排尽空气，接通电磁阀电源。然后慢慢地按正常运转方向转动传动齿轮。
First in the fuel injection pump drive shaft is provided with the driving gear, and the cavity is filled with diesel, exhaust air, through the power of the electromagnetic valve. Then slowly according to the normal operation of the direction of rotation gear.
②缓慢转动发动机，使第一缸处于规定的最佳供油角位置。
The slow rotation engine, the first cylinder is provided the optimum fuel angular position.
③将喷油泵装在发动机上，使传动齿轮与发动机上相应的驱动齿轮相啮合。
The fuel injection pump mounted on the engine, the transmission gear and engine on the corresponding drive gear.
注意：在装配过程中要特别小心，防止喷油泵的传动齿轮转动，以保证喷油泵开始供油的正确位置。
Note: in the assembly process to be especially careful, prevent the fuel injection pump drive gear to rotate, so as to ensure the correct position of the fuel injection pump start oil.
④旋紧喷油泵法兰上的紧固螺母。
④tighten fastening nuts on the flange of fuel injection pump.
⑤转动发动机曲轴，仔细观察喷油泵第一缸开始出油时的提前角是否符合规定。若供油提前角尚有偏差，可用转动油泵外壳(将油泵外壳沿油泵转动方向旋转)的方法来调整。如提前角相差较多，通过转动油泵外壳还达不到规定时，则必须将油泵拆下，重新调整传动齿轮与油泵传动轴齿轮的啮合位置，直到供油提前角符合规定为止。
The rotation of the engine crankshaft, careful observation of the first cylinder oil injection pump starts when advance angle is consistent with the provisions. If the fuel supply advance angle and deviation, available rotary oil pump housing ( oil pump casing pump rotation along the direction of rotation ) method to adjust. As the advance angles are more, by rotating the pump shell is not up to the requirements, must be removed to adjust oil pump, gear and oil pump driving shaft gear position, until the fuel supply advance angle in accordance with the provisions.
