Rack redundant electromagnetic driver of oil pump for diesel engine

Abstract

This invention provides a superfluous solenoid-drive device of the diesel-fuel oil pump rack. The device includes the hard surface and the executing agency in it, the inductive element, the locating guide mechanism. The executing agency includes the spigot shaft and the gag bit together with the loop outside the spigot shaft. The inductive element includes the sensor, the connected pressure pad and the attached spring of the sensor. The locating guide mechanism includes the positioning spring, the joint lever of the positioning spring and the steering bar. The loop mentioned is double winding and the sensors of the inductive element include two linear movement sensors, sensing lever and the joint lever of the sensor. This invention makes sure the rack drive device of the diesel-fuel oil pump can continue working through another loop and sensor when the single loop and sensor are broken. Meanwhile, it guarantees the reliability of the diesel-fuel machine and satisfies the special demand of the high-pressure oil pump towards the wire-drive device.

Description

(1) Technical field [0001] The invention relates to the field of diesel engine control, and specifically designs the field of a control system for electromagnetically adjusting non-electric variables. (2) Background technology [0002] With the development of marine diesel engine technology and electronic technology, the rack control method of marine diesel engine oil pump has also developed into an electronic control method, which is often called an electronic governor. Its purpose is to complete the function of the early mechanical governor through electronic control, thereby improving various performance indicators of the diesel engine. In order to complete the rack electronic control of the high-pressure oil pump of the marine diesel engine, on the basis of the electronic governor, there must be a suitable oil pump rack drive device to convert the electric power of the electronic governor into a non-electric control diesel engine high-pressure oil pump rack.

Problems solved by technology

Its disadvantages are: the reliability of the single-winding coil and single sensor is low; the linearity of the rotation angle sensor is poor; the sensor has no gap elimination mechanism; the motion conversion mechanism is complicated, which reduces the response speed and control accuracy of the device; The linear motion of the oil pump is directly connected to the rack, so that during the long-term working process, the fuel can easily enter the interior of the actuator and cannot be discharged, and the accumulation of too much fuel will block the movement of the armature and cannot be controlled.

In summary, its performance and reliability cannot meet the requirements of the high-pressure oil pump of the diesel engine for its electromagnetic drive device
