Abstract

An electronic speed regulating device for a diesel engine includes an oil-regulating element (1) of an injection pump, a pin roll (2), a control module, a motor (3) and its rotating shaft (4), a stem (5) and a speed-regulating lever (7) etc. The regulator omits a mechanical centrifugal speed governor and controls the motor (3) through a load signal by using the control module, and transfers the angular displacement of the motor (3) to the angular displacement of the oil-regulating element (1) of the injection pump by a series of driving devices. Compared with the conventional mechanical centrifugal speed governor, the motion piece of the speed regulator has lighter weight, smaller inertia and more sensitive reaction. The speed-regulating lever (7) adopting certain lever ratio refines the step displacement of the stepping motor (3) and sends it to the oil-regulating element (1) of the injection pump, which can regulate the oil supply quickly and accurately and reduce the fluctuation ratio of the diesel rotary speed.

Description

一种柴油机的电子调速装置  Electronic speed regulating device for diesel engine
一、技术领域 First, the field of technology
本发明属于柴油机的调速装置， 特别涉及一种风冷柴油机的调速装置。 属于 活塞式内燃机技术领域。 二、 背景技术  The invention belongs to a speed regulating device of a diesel engine, and particularly relates to a speed regulating device for an air-cooled diesel engine. It belongs to the technical field of piston internal combustion engines. Second, the background technology
调速器是根据发动机负荷变化而自动调节供油量， 从而保证发动机的转速稳 定在很小的范围内变化。 型式： 按功能分有两极调速器、 全程调速器、 定速调 速器和综合调速器； 按转速传感方式分有气动式调速器、 机械离心式调速器和复 合式调速器。  The governor automatically adjusts the fuel supply according to changes in engine load, thus ensuring that the engine's rotational speed is stable within a small range. Type: According to the function, there are two-pole governor, full-speed governor, fixed-speed governor and integrated governor; according to the speed sensing method, there are pneumatic governor, mechanical centrifugal governor and compound type Speeder.
机械离心式调速 ¾是根据弹簧力和离心力相平衡进行调速的， 工作中， 弹簧 力总是将供油拉杆向循环供油量增加的方向移动； 而离 ' 力总是将供油拉杆向循 环供油量减少的方向移动。 当负荷减小时， 转速升高， 离心力大于弹簧力， 供油 拉杆向循环供油量减少的方向移动， 循环供油量减小， 转速降低， 离心力又小于 弹簧力， 供油拉杆又向循环供油量增加的方向移动， 循环供油量增加， 转速又升 高， 直到离心力和弹簧力平衡， 供油拉杆才保持不变。 这样转速基本稳定在很小 的范围内变化。  The mechanical centrifugal speed regulation 3⁄4 is based on the balance of the spring force and the centrifugal force. In operation, the spring force always moves the oil supply rod to the direction of increasing the circulating oil supply; and the force is always the oil supply rod. Move to the direction in which the cycle oil supply is reduced. When the load decreases, the rotation speed increases, the centrifugal force is greater than the spring force, the oil supply rod moves in the direction of decreasing the circulating oil supply, the circulating oil supply decreases, the rotation speed decreases, the centrifugal force is smaller than the spring force, and the oil supply rod is supplied to the circulation. When the amount of oil increases, the amount of circulating oil increases, and the speed increases again. Until the centrifugal force and the spring force balance, the oil supply rod remains unchanged. This speed is basically stable and varies within a small range.
反之当负荷增加时， 转速降低， 弹簧力大于离心力， 供油拉杆向循环供油量 增加的方向移动， 循环供油量增加， 转速升高， 弹簧力又小于离心力， 供油拉杆 又向循环供油量减小的方向移动， 循环供油量减小， 转速又降低， 直到离心力和 弹簧力平衡。  Conversely, when the load increases, the rotation speed decreases, the spring force is greater than the centrifugal force, the fuel supply rod moves in the direction of increasing circulating oil supply, the circulating oil supply increases, the rotation speed increases, the spring force is smaller than the centrifugal force, and the fuel supply rod is supplied to the circulation. When the amount of oil decreases, the amount of circulating oil is reduced, and the number of revolutions is reduced until the centrifugal force and the spring force are balanced.
目前， 一般的柴油机均使用机械离心式调速器， 但是， 由于结构所限， 这种 调速器的响应速度较慢， 已经难以满足现代用户对柴油机转速稳定性的更高要 求， 且调速杠杆长， 结构复杂。  At present, general diesel engines use mechanical centrifugal governors. However, due to the limited structure, the speed response of such governors is slow, which has been difficult to meet the higher requirements of modern users for the stability of diesel engines. The lever is long and the structure is complicated.
而在一般电调调速器中， 执行器元件多采用电磁铁， 但对小型柴油机来讲， 这种方案成本较高， 因此， 电调在小型柴油机上的使用受到很大的限制。 三、 发明内容 In the general electric governor, the actuator components are mostly electromagnets, but for small diesel engines, this solution is costly. Therefore, the use of ESCs on small diesel engines is greatly limited. Third, the invention content
本发明针对上述技参问题， 提供一种成本低廉的电子调速器的执行系统， 它 结构简单， 响应灵敏， 不仅能降低柴油机的转速波动率， 还使其布置更加紧凑。  The present invention is directed to the above-mentioned technical problem, and provides an inexpensive execution system of an electronic governor.

A sealing device is provided at the upper opening of the bearing hole. A rotating handle is fixed to the lower end of the motor shaft. A pin axis parallels the motor shaft and passes through the corresponding pin hole on the crankcase from the top to the bottom of the crankcase. The pin shaft and the crankcase pin hole hole do not cause relative movement between the pin shafts. At the lower end, there is a mechanical device for preventing the speeding lever from falling off, and the cooperation between the speed adjusting lever and the pin shaft can rotate the speed adjusting lever around the pin shaft. The pin is arranged in such a position that the speed-adjusting lever is just slidably connected to the action-executing structure of the rotary handle and the other end is slidably coupled to the oil-regulating element of the fuel injection pump. The stepping motor drives the motor shaft to make the rotating handle fixed to the lower end of the rotating shaft to move the speed adjusting lever, and the speed adjusting lever converts the angular displacement of the motor into the angular displacement of the oil adjusting element of the fuel injection pump. The lever ratio of the speed lever (the ratio of the active arm to the follower arm) is R: 1 < R < 3 o
该发明产生的有益效果为： 采用电信号控制步进电动机的调速装置取代原有 的机械离心式调速器， 油泵响应速度更快， 反应更灵敏， 采用一定杠杆比 R的调 速杠杆， 将步进电机的步位移通过杠杆比进行细化， 再传到喷油泵油量调节元 件， 使喷油泵供油量调整更精细， 从而实现了快速、 精确地调整供油量， P争低柴 油机转速波动率和稳定调速率的目的。 四、 附图说明  The beneficial effects produced by the invention are as follows: The electric speed signal is used to control the stepping motor to replace the original mechanical centrifugal governor, and the oil pump has a faster response speed and a more sensitive reaction, and adopts a speed lever with a certain lever ratio R. The step displacement of the stepping motor is refined by the lever ratio, and then transmitted to the fuel pump oil quantity adjusting component, so that the oil supply amount of the fuel injection pump is finely adjusted, thereby realizing quick and accurate adjustment of the oil supply amount, and P is low in diesel engine.
