Abstract
The utility model provides an oil supply system for a hydraulic steering engine, which can directly drive an oil pump of steering engine equipment by using a pulley for a main engine of a ship so as to fulfill the aim of saving oil. The system comprises the oil pump connected with an oil supply pipeline and an accumulator, wherein the accumulator and the oil pump are connected in parallel on the oil supply pipeline. In the oil supply system, hydraulic oil provided when the ship is not steered is stored by using the accumulator, and after the accumulator reaches a saturated state, the accumulator and the oil supply pump supply oil to the hydraulic steering engine for steering during the steering of the ship, so that an oil pump smaller than a common steering engine can be used; therefore, driving power required by the oil pump is greatly reduced; and when the main engine of the ship works normally, the oil supply of the oil supply pump is increased to be enough for the normal and continuous steering of the ship. The design can ensure that a larger ship can directly drive the oil pump of the steering engine equipment by using the main engine (or an auxiliary engine), so that the fuel consumption of the ship can be reduced.
Description
Technical field
The utility model relates to the fuel-feed system of hydraulic sterring engine.
Background technology
Hydraulic sterring engine is the steering equipment that is used on the boats and ships.Present present situation is: the hydraulic sterring engine of small-sized boats and ships is because of using power less, there are many steering wheels to be to use the oil pump (be called for short main frame band pump) of the main frame (diesel engine) of boats and ships with belt pulley direct drive hydraulic sterring engine equipment, and a standby cover electric motor driven oil pump (be called for short motor band pump) or subsidiary engine drive oil pump as back-up power source, when reaching normal navigation, boats and ships are the purpose of starter-generator in addition, for boats and ships have been saved the fuel oil of supply generator work, reduce oil consumption.And the hydraulic sterring engine of bigger boats and ships is because of using power bigger, and the main frame of boats and ships (diesel engine) belt pulley driving power does not have obvious increase, be difficult to drive the oil pump of steering wheel equipment with the main frame belt pulley, so big boats and ships have to use generator for electricity generation, the oil pump of direct motor drive steering wheel equipment is supplied with in electricity consumption again, has increased the oil consumption of boats and ships greatly.
In sum, if on some bigger boats and ships, the main frame (diesel engine) that can utilize boats and ships is with the oil pump (fuel-feed system) of belt pulley direct drive steering wheel equipment, and the oil consumption that then can save boats and ships becomes many shipowner users' hope.
Summary of the invention
The purpose of this utility model provides a kind of fuel-feed system of hydraulic sterring engine, and this fuel-feed system can utilize the oil pump of the main frame of boats and ships with belt pulley direct drive steering wheel equipment, thereby reaches the purpose of fuel-economizing.
The fuel-feed system of hydraulic sterring engine of the present utility model comprises the oil pump that links to each other with oil feed line, and it also comprises with oil pump and is connected in energy storage on the oil feed line.
The beneficial effects of the utility model: according to the hydraulic sterring engine practical working situation, the applicant analyzes and draws, steering wheel is under the situation that main frame is worked at a slow speed, route speed is very slow, need continuous steering hardly, oil pump then provides hydraulic oil endlessly under the driving of the main frame of boats and ships, so the applicant utilizes energy storage that the hydraulic oil reservoir that boats and ships provide when the not steering is stored away, energy storage is reached capacity behind the state, when the boats and ships steering, supply with the hydraulic sterring engine steering with pump fuel feed, so just can select the oil pump work littler for use than general steering wheel, thereby reduced the required driving power of oil pump greatly, and when the main frame normal operation of boats and ships, the pump fuel feed amount increases, and foot is purchased the normal steering continuously of boats and ships.Such design can make bigger boats and ships use the directly oil pump of machine driving steering wheel equipment of main frame (or subsidiary engine), reduces marine fuel oil consumption.
Above-mentioned fuel-feed system, it also comprises the energy storage safety valve group that is connected with energy storage.Energy storage safety valve group comprises unloader valve and safety valve in parallel; Energy storage links to each other with oil return line by shutoff valve; The actuator port of energy storage safety valve group and shutoff valve communicate with pipeline between the energy storage; The oil outlet of energy storage safety valve group connects oil feed line; The oil inlet of energy storage safety valve group connects described oil pump.Preferably it also comprises governor valve, and the oil outlet of energy storage safety valve group connects the oil inlet of governor valve, and the oil outlet of governor valve connects oil feed line.
Description of drawings
Fig. 1 is the hydraulic system principle figure of the high-power main frame band of hydraulic sterring engine pump.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Referring to the schematic diagram of the hydraulic sterring engine fuel-feed system shown in 6 in the wire frame among Fig. 1, fuel-feed system mainly is made up of oil pump 4, unloader valve 21, safety valve 22, governor valve 3, energy storage 1 that main frame 5 drives, but the requirement additions and deletions that all the other annexes use according to the user.
Energy storage 1 comprises energy storage body 11 and shutoff valve 12.The energy storage body links to each other with oil return line T by shutoff valve.Energy storage safety valve group 2 comprises unloader valve 21 and safety valve 22 in parallel.The oil inlet of unloader valve 21 (oil inlet of energy storage safety valve group) joins with the oil pump oil outlet.The oil outlet of unloader valve 21 (also being the oil outlet of energy storage safety valve group) communicates with the oil inlet (actuator port of energy storage safety valve group) of safety valve, and the return opening of safety valve, the return opening of unloader valve all link to each other with oil return line T.The actuator port of energy storage safety valve group and shutoff valve communicate with pipeline between the energy storage.Cascade control valve 3 between the change-over valve in the oil outlet of energy storage safety valve group and the hydraulic tubing.
At the oil pump that main frame (when working at a slow speed) drives, the oil pump constantly hydraulic oil of output enters unloader valve, and this moment, the oil pump delivery rate only was 40%～80% of an actual required flow.When not steering, these hydraulic oil flow into energy storage by oil circuit A, and when the pressure in the energy storage arrived the setting pressure of unloader valve, unloader valve was connected oil-feed and oil return line T, and hydraulic oil flows back to fuel tank by oil return circuit T off-load.
When the hydraulic sterring engine steering, hydraulic oil in the energy storage because pressure higher (this pressure is far longer than actual working pressure (a.w.p.)) is joined with the hydraulic oil that oil pump supplies of host driven, is supplied with hydraulic sterring engine work together.Too fast for preventing the energy storage fuel feeding, in oil circuit C, be provided with governor valve 3 control fuel supply flow rates, guarantee hydraulic sterring engine with constant speed work, except that using the governor valve valve, also can the usage ratio change-over valve, flow regulating valve etc. has the valve member control rate of certain speed governing ability.
Safety valve plays protection energy storage (according to the related specifications regulation), generally is failure to actuate in the real work.
Pressure in the energy storage is approximately higher than more than 25% of maximum working pressure (MWP).The energy storage volume must guarantee at marine main engine during slow work speed, hydraulic sterring engine can the as prescribed time of rudder movement and load carry out once complete steering from meta → hard-over angle → meta.
