Abstract
The utility model discloses a hydraulic system of a pressure oil tank of a side thruster, comprising the pressure oil tank, wherein an air inlet of the pressure oil tank is connected with a pressure-reducing valve which is connected with an air source; an oil inlet of the pressure oil tank is connected with an oil tank; and an oil passage of the pressure oil tank is communicated with the oar grain inner cavity of the thruster. The utility model provides hydraulic system of the pressure oil tank of the side thruster, which can be conveniently installed and simplifies the pipeline.
Description
Technical field
The utility model belongs to shipbuilding industry, relates in particular to a kind of boats and ships side thruster pressure oil tank hydraulic efficiency pressure system.
Background technology
Adjustable pitch propeller is made up of five big parts such as blade, propeller hub mechanism, oil distributor, hydraulic efficiency pressure system and electronic telecontrol system or system.Hydraulic efficiency pressure system is made up of roll adjustment oil circuit and gravity oil circuit: ship advances, retreats the roll adjustment oil circuit to provide, speed change and requirement such as stop; The gravity oil circuit is suspended on the gravity oil that is deep to few two meters gravity tank from draft extreme by one provides certain pressure to guarantee that the hydraulic pressure outside propeller hub internal pressure and the oar housing balances each other.But in actual ship form, stem can provide required height to hang gravity tank, and the height of ship stern is often all not enough; Therefore a lot of shipyards all hang over fore with the gravity tank of bow thruster and stern thruster, are pulled to the stern thruster by long pipe runs, and it is complicated that this makes that pipeline connects, waste material not only, and cause unnecessary trouble to site operation.
Summary of the invention
For the installation inconvenience that overcomes existing boats and ships side thruster gravity tank hydraulic efficiency pressure system, the deficiency of pipeline complexity, the utility model provides a kind of easy for installation, side thruster pressure oil tank hydraulic efficiency pressure system of simplifying pipeline.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of side thruster pressure oil tank hydraulic efficiency pressure system, comprise pressure oil tank, the admission port of described pressure oil tank connects reducing valve, and described reducing valve connects source of the gas, the oil inlet of described pressure oil tank connects fuel tank, and the fluid passage of described pressure oil tank is communicated with angle of rake Jiang Grains inner chamber.
Further, safety valve is installed in the described pressure oil tank.
Further again, low pressure alarm is installed in the described pressure oil tank.
Further, the oil inlet of described pressure oil tank is provided with switch valve, and liquid level detector is installed in the described pressure oil tank, and described liquid level detector is connected fluid level controller with switch valve.
The beneficial effects of the utility model mainly show: easy for installation, simplification pipeline.
Description of drawings
Fig. 1 is the scheme drawing of side thruster pressure oil tank hydraulic efficiency pressure system;
Fig. 2 is the constructional drawing of pressure oil tank.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, a kind of side thruster pressure oil tank hydraulic efficiency pressure system, comprise pressure oil tank 1, the admission port of described pressure oil tank 1 connects reducing valve, described reducing valve connects source of the gas, the oil inlet of described pressure oil tank connects fuel tank, and the fluid passage of described pressure oil tank is communicated with angle of rake Jiang Grains inner chamber.
Safety valve is installed in the described pressure oil tank.Low pressure alarm is installed in the described pressure oil tank.The oil inlet of described pressure oil tank is provided with switch valve, and liquid level detector is installed in the described pressure oil tank, and described liquid level detector is connected fluid level controller with switch valve.
The working process of present embodiment: the roll adjustment oil circuit: pump is by driven by motor, pressure oil arrives the 3-position 4-way solenoid directional control valve by pressure filter and check valve, when electromagnetic valve during at meta, system is in unloading condition, and fluid directly flows back to fuel tank through check valve and return filter; When being in commutation position, system is in the roll adjustment state: positive car roll adjustment: pressure oil A mouth arrives propeller hub oil cylinder rodless cavity promotion piston and finishes positive car roll adjustment to the right, and rod chamber fluid flows back to fuel tank by the B mouth; The reversing roll adjustment: pressure oil B mouth arrives propeller hub oil cylinder rodless cavity promotion piston and finishes the reversing roll adjustment left, and rodless cavity fluid flows back to fuel tank by the A mouth.The pressure of total system is controlled by by pass valve, and the roll adjustment time is controlled by governor valve.
The pressure oil circuit: shipyard provides the source of the gas that is roughly 1Mpa, arrives pressure oil tank by reducing valve to required pressure, and the fluid of pressure oil tank leads to oar Grains inside, and the outer hydraulic pressure of certain pressure of its maintenance and oar housing is balanced each other; Safety valve is housed on the pressure oil tank, guarantees that its pressure is unlikely to too high and influences the leak tightness of Qi Jiang Grains; The low pressure alarming signal is housed simultaneously, in case hypotony is just reported to the police.Scurry mutually for the fluid that prevents hydraulic reservoir and pressure oil tank and to make that the oil level of pressure oil tank is too high or too low, fluid level controller and electromagnetic switch valve are housed on pressure oil tank, and have a drain tap, when the liquid level full level alarm in the fuel tank bottom, electromagnetic switch valve is opened, and pressure oil tank begins draining; Report to the police until the liquid level meta, electromagnetic switch valve is closed; Cross when low when liquid level, the fluid level controller low alarm needs to give the pressure oil tank oiling.
In the present embodiment, changing the gravity tank of prior art into pressure oil tank Jiang Grains pressure inside is not that gravity by fluid provides, but provide required pressure and oar housing hydraulic pressure outward to balance each other by air pressure, so just do not exist because the not high enough problem that does not provide required pressure and hang fuel tank nowhere of ship type; Do not need the fuel tank of stern thruster is placed in stem yet, be connected to the stern thruster by long pipe runs.Not only simplified the pipeline connection by improving, saved material, but also greatly reduced fault rate.
Gravity tank is for providing required pressure, must hang over specific height, and pressure oil tank is to provide pressure by air pressure, there is not the certain location requirement, only need to come the placement force fuel tank to get final product according to on-site actual situations, not only simplified the pipeline connection, returned the shipyard site operation and bring great convenience.
