Embodiment Construction

[0025] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0026] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a diesel engine speed regulator parameter calibration method. The diesel engine speed regulator parameter calibration method comprises the following steps of: connecting a signal generator into a stepping motor control panel; adjusting the signal generator to enable the signal generator to output a 4mA current signal, and setting a first position parameter; shifting a selection switch of the stepping motor control panel to a first position, pressing down a key switch, and storing the value of 4mA in a system; adjusting the signal generator to enable the signal generator to output a 20mA current signal, and setting a second position parameter; shifting the selection switch of the stepping motor control panel to a second position, pressing down the key switch, and storing the value of 20mA in the system; starting the diesel engine, adjusting the signal generator to output the 20mA current signal, and setting a third position parameter; and shifting the selection switch of the stepping motor control panel to a third position, pressing down the key switch, and storing the value of 20mA in the system. By forming a standard and unified parameter calibration method, the corresponding relation between the current and the set rotating speed is ensured, and the diesel engine can stably and reliably operate.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a method for calibrating parameters of a governor of a diesel engine. Background technique [0002] At present, the four-stroke medium-speed diesel engine has advanced performance indicators and is the leader in ship power. The speed control system of the medium-speed diesel engine mainly includes a governor, a stepping motor control board, an oil control rod system, a fuel injection pump and a fuel injector, etc. The governor adopts the hydraulic type. When the main control mode works, it receives a control current of 0-1A to control the throttle of the diesel engine. The larger the control current, the smaller the throttle of the diesel engine. When the backup control mode is working, it mainly depends on the stepping motor control board of the governor to control the stepping motor inside the governor, which is then used to adjust the throttle of the diesel engine and control th...
