Problems solved by technology
The governor is to automatically change the circulating oil supply of the fuel injection pump through the gear rod according to the change of the engine load, so as to realize the stable operation of the diesel engine within a certain speed range, so as to ensure that the speed of the engine changes within a small range. However, the current mechanical speed regulation The rotational speed of the governor fluctuates too much during work, and the adjustment means of the existing governor is limited, so it cannot realize automatic starting and thickening, and the adjustment is inconvenient, which increases the working hours and labor intensity, and reduces the productivity. Therefore, it is difficult to meet the matching requirements of diesel engines.

Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings: the three flyweight parts 1 transmit the action to the speed regulating lever part 13 through the speed regulating sleeve 2, and the protrusion of the flyweight 1a directly pushes the speed regulating sleeve 2 on the camshaft 11 , the displacement of the speed regulating sleeve 2 is transmitted to the fuel injection pump regulating gear rod 12 through the speed regulating lever.
[0013] Before starting, turn the speed regulating handle 9 counterclockwise to the maximum speed position, stretch the speed regulating spring 7, pull the second speed regulating lever 4, and drive the first speed regulating lever 3 to press the speed regulating sleeve 2 to the leftmost end, so that The stationary flyweight 1a is in a fully closed state. At this time, the idle spring 6 is stretched, and the protrusion a on it is close to the right side of the ring b of the second spee...

The invention relates to a mechanical variable speed governor of a fuel injection pump of a diesel engine. A tri-flyweight component (1) is fixedly combined with a camshaft (11), a first governor lever (3) and a second governor lever (4) are connected in series by the aid of a support shaft (10) to form a governor lever component (13) which is arranged on an engine body by the aid of the support shaft (10), a governor sleeve (2) is arranged between the governor lever component (13) and the tri-flyweight component (1), an idle spring (6) is arranged between the first governor lever (3) and the second governor lever (4), the upper end of the first governor lever (3) is connected with a driving lever (5) through a ball valve, one end of a governor spring (7) is connected with the bottom of the first governor lever (3), the other end of the governor spring (7) is connected with a governor handle (9) which is arranged on a governor handle seat through a semicircular shaft and a limiting screw, and the governor handle seat is fixed on the engine body. The mechanical variable speed governor of the fuel injection pump of the diesel engine automatically achieves cranking enrichment, idle speed governing, maximum speed limit control and the like.
Description
technical field [0001] The invention belongs to the field of governors of diesel engine fuel injection pumps, and in particular relates to a mechanical full-range governor of diesel engine fuel injection pumps. Background technique [0002] The speed characteristics of the fuel injection pump are very unfavorable to the diesel engine with changing working conditions. When the engine load changes slightly, the engine speed changes greatly. Mechanical governors are commonly used on diesel engines. The governor is to automatically change the circulating oil supply of the fuel injection pump through the gear rod according to the change of the engine load, so as to realize the stable operation of the diesel engine within a certain speed range, so as to ensure that the speed of the engine changes within a small range. However, the current mechanical speed regulation The rotational speed of the governor fluctuates too much during work, and the adjustment means of the existing gov...
