Abstract

The invention provides a hydraulic steering engine control system. The hydraulic steering engine control system comprises an oil cylinder, a three-position four-way solenoid directional valve, a check valve, a constant-pressure variable pump, a motor, a throttle valve and an oil tank. An oil inlet of the constant-pressure variable pump is connected with the oil tank. The motor is installed on the constant-pressure variable pump. An oil outlet of the constant-pressure variable pump is connected to an oil inlet of the check valve. An oil outlet of the check valve is connected with an oil port P of the three-position four-way solenoid directional valve, an oil port O of the three-position four-way solenoid directional valve is connected with the throttle valve, and the throttle valve is connected with the oil tank through an oil path. An oil port A of the three-position four-way solenoid directional valve is connected with a left cavity oil inlet of the oil cylinder. An oil port B of the three-position four-way solenoid directional valve is connected to a right cavity oil inlet of the oil cylinder. The oil returning throttling speed-adjusting loop is adopted, the steering speed is better controlled to enable a steering engine to work stably, and the hydraulic steering engine control system is simpler, more convenient to manage and suitable for small ships.

Description

technical field [0001] The invention belongs to the field of hydraulic control, in particular to a hydraulic steering gear control system. Background technique [0002] A steering gear is a large deck machinery on a ship. At present, the marine steering gear is mostly electro-hydraulic, that is, the hydraulic equipment is remotely operated by the electric equipment. There are two types: one is the reciprocating plunger steering gear, its principle is to produce linear motion through the conversion of high and low pressure oil, and convert it into rotary motion through the tiller. The other is the rotary vane steering gear. Its principle is that the high and low pressure oil directly acts on the rotor. It is small in size and efficient, but the cost is relatively high. [0003] The control system of the steering gear can be divided into mechanical type, electric type, hydraulic type, etc. The hydraulic control system has the advantages of small size, light weight, small foo...
