Abstract
The invention discloses a driving technology of a hydraulic press pump and an energy accumulator in the field of ship building. A rocking bar type four-valve distributor is arranged between a liquid filling tank and an air tank; an the energy accumulator is mounted on the rocking bar type four-valve distributor; high-pressure liquid is stored in the rocking bar type four-valve distributor; return cylinder draining valves are respectively arranged on two sides of the bottom of the rocking bar type four-valve distributor; a work cylinder water inlet valve is arranged at the top of the rocking bar type four-valve distributor; a movable cross beam is controlled by one draining valve to move downwards by means of dead weight from an upper stopping position; when the work cylinder water inlet valve is opened, the high-pressure liquid from the a high-pressure pump or the energy accumulator enters a work cylinder formfrom a liquid-filled valve cavity and acts on a plunger; the movable cross beam carries out pressure processing on workpieces; and a pressurizer consists of a low-pressure cylinder and a high-pressure cylinder is additionally arranged between the work cylinder and the corresponding valve. The driving technology disclosed by the invention has the beneficial effects that a load can be balanced; the hydraulic work efficiency can be increased; the operational capacity of equipment can be improved in an assisting manner; and meanwhile, the meeting of the requirement on transportation, mounting and stand adjustment is facilitated.
Description
Technical field
The present invention relates to the hydraulic technique field, relate in particular to a kind of hydraulic pressure pump for the shipbuilding field and accumulator drive technology.
Background technology
Hydraulic system has that power is large, operating pressure and the flow adjustability is good, heat can be brought back the advantages such as fuel tank, adopt hydraulic system to produce more power than other devices, under equal power, the volume of hydraulic means is little, lightweight, power density large, compact conformation; Simultaneously, the hydraulic means Comparision is steady because lightweight, inertia is little, reaction is fast, hydraulic means is easy to realize quick startup, braking and commutating frequently.Along with the development of China's industry and science and technology, hydraulic transmission technology has obtained at aspects such as auto industry, shipbuilding industry, power industries using more and more widely, and hydraulic press is more and more welcomed by the people also.The working cycles of hydraulic press generally comprise stop, eharge stroke, impulse stroke and backhaul, above-mentioned different strokes are realized by the action of various valves in the control system control hydraulic system.But the hydraulic system transmission component for the hydraulic press that has the shipbuilding field now exists a lot of problems from method of operating, working method, numerous and diverse different angles such as structure, and this causes work poor efficiency, heavier, the high expensive of weight of equipment.
Summary of the invention
But the purpose of this invention is to provide a kind of balanced load, can improve hydraulic efficient, good stability, can reduce labour intensity, the auxiliary hydraulic pressure pump and the accumulator drive technology that are used for the shipbuilding field that improves the equipment operation ability, with many deficiencies of solution prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of hydraulic pressure pump and accumulator drive technology for the shipbuilding field mainly are comprised of following steps:
⑴ at first arrange rocker-type four valve distributors between pressure-loaded prefilling tank and air tank, accumulator and storage high pressure liquid are installed, when backhaul or when stopping, the highly pressurised liquid of pump output can partly be stored in the accumulator, and when hydraulic press needs a large amount of highly pressurised liquid, is then supplied simultaneously by pump and accumulator;
⑵ install respectively a kicker cylinder draining valve in four valve dispenser bottom both sides, be positioned at four valve dispenser top a working cylinder water intaking valve is installed, descending by deadweight from upper stop position by one of them draining valve control moved cross beam, the liquid in the kicker cylinder flows back to low pressure tank or pressurized can;
⑶ be filled with the compressed air of 5 * 105Pa on pressurized can top, under the hydraulic pressure effect in working cylinder and pressurized can, prefill valve is backed down, and the liquid in the pressure-loaded prefilling tank is under low-pressure compressed air or action of gravitation, the a large amount of inflow in the working cylinder realized the downward eharge stroke of moved cross beam idle running;
⑷ last, when the working cylinder water intaking valve is opened, from high-pressure pump or the next highly pressurised liquid of accumulator, enters working cylinder through the topping up valve pocket, and act on the plunger, by moved cross beam workpiece carried out pressure processing;
⑸ set up the booster that is comprised of low pressure (LP) cylinder and high pressure cylinder between working cylinder and corresponding valve, low pressure (LP) cylinder is supplied with the liquid of certain pressure by pump or accumulator.
Of the present inventionly for the hydraulic pressure pump in shipbuilding field and the beneficial effect of accumulator drive technology be: but balanced load, can improve hydraulic efficient, the auxiliary equipment operation ability that improves, simultaneously, be conducive to adapt to the demand of transportation, installation, accent frame, can improve the operation controllability, reduce labour intensity.
The specific embodiment
The embodiment of the invention described hydraulic pressure pump and accumulator drive technology for the shipbuilding field, its key step comprises:
⑴ at first arrange rocker-type four valve distributors between pressure-loaded prefilling tank and air tank, accumulator and storage high pressure liquid are installed, when backhaul or when stopping, the highly pressurised liquid of pump output can partly be stored in the accumulator, and when hydraulic press needs a large amount of highly pressurised liquid, is then supplied simultaneously by pump and accumulator;
⑵ install respectively a kicker cylinder draining valve in four valve dispenser bottom both sides, be positioned at four valve dispenser top a working cylinder water intaking valve is installed, descending by deadweight from upper stop position by one of them draining valve control moved cross beam, the liquid in the kicker cylinder flows back to low pressure tank or pressurized can;
⑶ be filled with the compressed air of 5 * 105Pa on pressurized can top, under the hydraulic pressure effect in working cylinder and pressurized can, prefill valve is backed down, and the liquid in the pressure-loaded prefilling tank is under low-pressure compressed air or action of gravitation, the a large amount of inflow in the working cylinder realized the downward eharge stroke of moved cross beam idle running;
⑷ last, when the working cylinder water intaking valve is opened, from high-pressure pump or the next highly pressurised liquid of accumulator, enters working cylinder through the topping up valve pocket, and act on the plunger, by moved cross beam workpiece carried out pressure processing;
⑸ set up the booster that is comprised of low pressure (LP) cylinder and high pressure cylinder between working cylinder and corresponding valve, low pressure (LP) cylinder is supplied with the liquid of certain pressure by pump or accumulator.
