Description
One, affiliated field:
The present invention relates to mechanical equipment technical field, particularly a kind of hydraulic machinery energy storage apparatus.
Two, background technique:
At present, vegetable oil pressing machine tool equipment is used more pressing machine that pair roller and biconjugate roller pressing machine are arranged both at home and abroad.This class pressing machine can be divided into two kinds of the tight roller of spring and liquid pressure rollers by the tight roller mode of roll.The former regulates inconvenience because roll gap pressure is little, and the strip plate effect is bad; The latter is because its roll gap pressure is larger, and rotating speed is also very fast, therefore the treating capacity of unit roller length is just large, is widely used.The hydraulic accumulating device of the tight roller pressing machine of hydraulic pressure that this application is wider is also not ideal.The accumulator of common this hydraulic accumulating device is that a kind of pressure energy hydraulic oil in hydraulic accumulating device is stored up, the energy storage device again it discharged again when needed.Commonly used have two kinds of piston type and bladder accumulators.Piston accumulator is comprised of piston, cylinder body, gas charging valve, and epicoele gas is filled with from gas charging valve; Cavity of resorption fluid is communicated with hydraulic system through oilhole, and piston separates gas and fluid, and during use, oilhole is communicated with hydraulic system, and piston separates gas and fluid.During use, be filled with the nitrogen of predetermined pressure, then fluid entered through hole promote piston to rise to piston in state of equilibrium, make system reach desired pressure.The accumulator structure of this structure is simple, and stable working is reliable, convenient for installation and maintenance, and the life-span is long.Its shortcoming is the impact due to piston inertia and surface friction drag, reacts sensitive not, and capacity is less, due to the sealability requirement being arranged between cylinder barrel and piston, so manufacturing expense is higher.Be generally used for accumulation of energy or pulse for middle high-pressure system absorption pressure.The air bag that bladder accumulator is made by gas charging valve, synthetic rubber, housing that homogeneous is seamless, poppet valve etc. form.First inflate (being generally nitrogen) by gas charging valve to air bag before accumulator work, close all the time during gas charging valve work.Poppet valve can make fluid enter in accumulator, and in the time of preventing again that fluid from all discharging, air bag expands outside container.The advantage of bladder accumulator is that air bag inertia is little, is quick on the draw, and easily safeguards.Shortcoming is that capacity is little, and air bag and housing are manufactured difficulty.Above-mentioned accumulator due to the pressing machine use, while bringing into operation, can obtain comparatively ideal strip plate effect, but, along with the prolongation of working time, usually there will be following point: the one, hydraulic-pressure pump needs operation continuously, can cause hydraulic oil temperature to raise, reduced viscosity, oil cylinder working-pressure reduces, and the material of race phenomenon is arranged during roll, directly affects the strip plate quality; The 2nd, because oil pump moves continuously, power consumption is large, wastes energy; The 3rd, in hydraulic system, each component are fragile, and fault is many, and the life-span is short, and maintenance and amount of maintenance are large; The 4th, yield poorly.Present stage is in the urgent need to a kind of improvement joint and economize the energy, in the time of can realizing starting shooting, hydraulic-pressure pump only needs to start the very short time (for example 3 minutes) in every 24 hours, the system that just can guarantee is normally moved, power consumption (electricity) is 1/400 of original hydraulic rolling mill, extend the working life of oil pump, can realize that a hydraulic system can be for 4-6 platform pressing machine simultaneously, pressure is large, flexible adjustment, easy to operate, easily safeguard, can realize automatically tight roller and minute roller, reasonable in design, floor space is little, a kind of hydraulic machinery energy storage apparatus that cost is lower.
