Starter integrated with fuel oil delivery pump and control method

Abstract

The invention discloses a starter integrated with a fuel oil delivery pump, belongs to the field of starters, and solves the problem of a large number of parts caused by a split structure of a traditional starter and a fuel oil delivery pump. The starter comprises a starter body, one end of an armature shaft of the starter body is connected with a diesel engine flywheel gear ring through a clutchassembly. The other end of the armature shaft of the starter body is connected with a fuel oil delivery pump, an oil inlet pipe of the fuel oil delivery pump is communicated with an oil tank, an oil outlet pipe of the fuel oil delivery pump is in communication with a diesel engine fuel oil system ppieline, a bypass oil pipe is arranged between the oil inlet pipe and the oil outlet pipe, and an electromagnetic valve is arranged on the bypass oil pipe. A control system is further included. The invention further provides a control method of the starter integrated with the fuel oil delivery pump.According to the starter and the control method, the number of parts is reduced, and the starter not only can be used as the fuel oil system pipeline before a diesel engine is started to exhaust air,but also can be used as a common fuel oil delivery pump of the diesel engine.

Description

technical field [0001] The present invention relates to a starter, more specifically, it relates to a starter integrated with a fuel delivery pump and a control method. Background technique [0002] After the diesel engine has been parked for a period of time, air is likely to enter the fuel system pipeline, resulting in difficulty in starting or even failure to start. For this reason, it is usually necessary to manually operate the hand-operated fuel pump, or start the electric fuel pump to work, to remove the air in the fuel system, so that the diesel engine can start normally and quickly. [0003] However, manual operation of the manual mechanical fuel delivery pump has problems such as low efficiency, inconvenient operation, long pressure build-up time in the fuel system pipeline, poor degassing effect, etc., and it must be manually operated close to the position of the diesel engine, which is difficult to meet the requirements of long-distance Starting requirements for...

AI Technical Summary

Problems solved by technology

[0003] However, manual operation of the manual mechanical fuel delivery pump has problems such as low efficiency, inconvenient operation, long pressure build-up time in the fuel system pipeline, poor degassing effect, etc., and it must be operated manually close to the position of the diesel engine, which is difficult to meet the requirements of long-distance Starting requirements for diesel engines for unattended type applications

As for the electric fuel delivery pump, although its efficiency is higher, its split structure requires more parts, which leads to a higher failure rate and a greater increase in the cost of the diesel engine.
