Problems solved by technology

The diesel engine fails to start for some reason, try the second or third start, hoping to start the diesel engine, if the interval between the second start is too short, the battery voltage has not been fully recovered, start again, resulting in a decrease in the power output of the starter motor, affecting the battery In the case of no supplementary charging within 30 minutes, the number of starts of the diesel engine will also affect the service life of the battery

Embodiment Construction

[0022] In order to make the purpose of the present invention and technical scheme statement clearer, the present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0023] Such as figure 2 shown. The capacity of the storage battery NP is 100 ampere hours, 12 volts, the upper end is positive (+), the lower end is negative (-), and it is connected to the ground. The "ground" in the present invention is the diesel engine body started by the starter motor D E, that is to say, the surface E of the fuselage is the common terminal "ground" of the negative pole.

[0024] The time relay includes a time relay coil KT and three contacts, one of which is the delay opening contact KT1 of the time relay when it is powered on, which is used to limit the starting window time of the diesel engine. The starting window time set in this embodiment is 45 seconds In order to avoid damage to the battery NP and starter motor D caused by the diesel e...

Abstract

A starter motor control system, the positive pole of the battery is connected to the first contact of the start button, the reset button, the coil of the time relay, and the negative pole of the battery; the time relay self-protects the first contact of the start button; Two circuits, one to pulse contact, start contactor coil, battery negative pole, the other to time relay delay contact, protection relay contact, dual-time intermittent automatic cycle relay power supply, battery negative pole; the time relay coil is connected in parallel to one alarm lamp ; An auxiliary relay coil is also connected in parallel on the power supply of the dual-time intermittent automatic cycle relay; the auxiliary relay contact is self-protected to the second contact of the start button; ; The positive pole of the battery is connected to the B terminal of the starter motor. The invention avoids undertime and overtime starting of the diesel engine by setting the starting time of the diesel engine, and meets the starting requirements of the lifeboat diesel engine.

Description

technical field [0001] The invention relates to a starter motor control system, in particular to a lifeboat diesel engine starter motor control system, which belongs to the technical field of diesel engine protection. Background technique [0002] The starting method of the lifeboat diesel engine (that is, the main engine of the lifeboat) is mainly the electric starter motor, such as figure 1 As shown in the schematic diagram of the starter motor structure, after the start button of the starter motor is pressed, the (S) terminal on the motor is connected to the battery, the electromagnetic switch is energized, and the iron core in the electromagnetic switch overcomes the spring resistance to move to the left, driving the gear of the mesher to extend Out, when the mesher gear and the flywheel ring gear of the diesel engine are fully meshed in place, that is, when the inner iron core of the electromagnetic switch moves to the left and reaches the limit position under the actio...
