Detailed Description
The invention will be further described with reference to specific embodiments shown in the drawings.
Referring to fig. 2, the novel hydraulic steering engine for the ship comprises a steering mechanism 1, and further comprises an electromagnetic steering oil path 2 and a manual steering oil path 3 which are independent from each other and supply oil. The input end of the electromagnetic directional steering oil way 2 is connected with a first oil tank 4, and the output end of the electromagnetic directional steering oil way 2 is connected with the steering mechanism 1 through an automatic isolating valve 5. The input end of the manual steering oil path 3 is connected with a second oil tank 6, and the output end of the manual steering oil path 3 is connected with the steering mechanism 1 through an automatic isolating valve 5. The electromagnetic directional steering oil way 2 is provided with a first isolation oil way 7 connected with a first control end of the automatic isolation valve 5, and correspondingly, the manual steering oil way 3 is provided with a second isolation oil way 8 connected with a second control end of the automatic isolation valve 5. A motor pump 9, an electromagnetic directional valve 10 and a steering engine special valve 11 are sequentially arranged from the input end to the output end of the electromagnetic directional steering oil way 2, the motor pump 9 is driven by a motor, and one end of the first isolation oil way 7 is connected with the output end of the motor pump 9. A main engine pump 12, a manual hydraulic steering gear 13 and a steering engine special valve 11 are sequentially arranged from the input end to the output end of the manual steering oil circuit 3, the main engine pump 12 is driven by a ship main engine, and one end of a second isolation oil circuit 8 is connected with the output end of the main engine pump 12. By arranging the electromagnetic steering oil way 2 and the manual steering oil way 3 which are mutually independent in oil supply, when one oil way breaks down, the broken oil way can be completely isolated, and the other oil way is started to continue steering to enable the ship to sail normally, so that the steering safety can be effectively improved. By arranging the automatic isolation valve 5, the first isolation oil path 7 and the second isolation oil path 8, when the electromagnetic steering oil path 2 is started, hydraulic oil flows into the first control end of the automatic isolation valve 5 from the first isolation oil path 7, the hydraulic oil in the electromagnetic steering oil path 2 can be controlled to flow into the steering mechanism 1 from the automatic isolation valve 5, and the isolation of the manual steering oil path 3 is realized. When the manual steering oil path 3 is started, the hydraulic oil flows into the second control end of the automatic isolation valve 5 from the second isolation oil path 8, so that the hydraulic oil of the manual steering oil path 3 can be controlled to flow into the steering mechanism 1 from the automatic isolation valve 5, and the electromagnetic steering oil path 2 is isolated. Through the organic combination of the oil way, the automatic isolating valve and the isolating oil way which are mutually independent for oil supply, the fault oil way can be automatically and completely isolated, and meanwhile, the other oil way can be rapidly switched to continue steering to enable the ship to sail normally, so that the problem that in the prior art, a worker needs to manually close the fault pipeline to the stern rudder cabin to cause long time consumption is solved, the ship sailing is prevented from being influenced due to the fact that the steering engine cannot be controlled for a long time, and the safety is effectively improved. The first oil tank 4 corresponding to the electromagnetic steering oil circuit 2 and the second oil tank 6 corresponding to the manual steering oil circuit 3 are arranged, so that the situation that the whole hydraulic steering engine cannot work due to insufficient hydraulic oil in one oil tank can be avoided, and the working robustness of the whole hydraulic steering engine is improved.
The hydraulic component structure of hydraulic steering wheel is mostly the slide valve type, and it is sealed that no sealing washer is between case and the valve body, leans on fitting surface mechanical seal, and the fit clearance is 0.008 ~ 0.012 mm. The structure has the problem that the hydraulic oil in the oil tank of one set of oil way leaks into the oil tank of the other set of oil way due to the fact that a small amount of internal leakage exists in the gap between the valve core and the valve body and the pipeline pressure and the like. Therefore, the two oil tanks are installed to ensure that the liquid levels of the hydraulic oil are in the same horizontal plane, and the top of the first oil tank 4 is communicated with the top of the second oil tank 6 through the high-level communicating pipe 14, so that the balance of the liquid levels of the hydraulic oil in the two oil tanks can be ensured. High-order communicating pipe 14 is connected with reserve oil tank 15, and first oil tank 4, second oil tank 6 all are equipped with low liquid level alarm 16, and when the hydraulic oil in the oil tank was not enough, open the ball valve on the reserve oil tank 15 and can mend oil.
In the design of a hydraulic system, the flow of hydraulic components, pipelines and joints is important to check, the flow of each joint on the electromagnetic steering oil way 2 is not lower than 110% of the flow of the motor pump 9, the flow of each joint on the manual steering oil way 3 is not lower than 110% of the flow of the main pump 12, and in this case, the rise of the pressure is not more than 10% of the set pressure of the safety valve. Because the host computer drives host computer pump 12 and has the flow variation, check and need select according to the flow calculation of oil pump when the biggest navigation rotational speed, otherwise cause the backpressure very easily too high, system noise is big, it is serious to generate heat, the host computer takes the pump stall scheduling problem, and the security of hydraulic steering wheel is seriously influenced to the misuse, and then arouses the safe operation of boats and ships.
The specification and model of the automatic isolating valve 5 can be selected according to actual needs, and in the embodiment, the model of the automatic isolating valve 5 is 23 YG-E25B.
When the ship sails in a storm or runs down a torrential river beach, the rudder stock is acted by negative moment, if external interference energy is large and the direction is opposite to the rotation direction of the rudder blade, the one-way valve in the steering engine special valve 11 plays a role of non-return, the connection between the oil cylinder and the oil pump is cut off, and the oil pump is effectively prevented from being changed into an oil motor. If the direction of the external negative moment is consistent with the steering of the rudder, the piston of the oil cylinder is accelerated, when an oil pump does not supply oil in time, the hydraulic system generates evacuation phenomenon, a large amount of air enters the hydraulic system to generate impact, vibration and noise, under the negative moment, the piston of the oil cylinder moves and accelerates, the pressure of an oil inlet cavity is reduced, the oil pressure of an oil outlet cavity is increased rapidly, the area of a return channel of the steering engine special valve 11 can be gradually reduced at the moment, the throttling effect is achieved, the balance effect is achieved, and the phenomena of 'rudder pause' and vibration and noise caused by one-step stopping of the piston are avoided. In the embodiment, the model of the steering engine special valve 11 is HDF16/H2S 15.
In the steering working conditions of port entry and exit, bank stop, turning, end drop and the like of a ship, a host is generally in an idle running state, and at the moment, the steering time of a hydraulic steering engine is required to meet the requirement of being less than or equal to 20 seconds, specifically, the reasonable matching between a host belt pulley and a host pump 12 belt pulley is made by increasing the displacement of the host pump 12 during design and fully considering the change range of the host rotating speed and the idle speed of the ship in the normal sailing process, so that the steering time of the steering engine when the host is in the idle speed can be met, and the rated rotating speed of the host pump 12 driven by the host cannot exceed during normal sailing. When the steering time is too fast during normal navigation, the driver can control the flow rate into the steering mechanism by the steering speed of the manual hydraulic steering 13, thereby obtaining the desired steering speed.
The above is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that several variations and modifications can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
