Description
Technical field
The present invention relates to a kind of hydraulic station energy saving device, is a kind of hydraulic station efficient energy-saving device of service intermittent specifically.
Background technique
At present the blast furnace hydraulic station is at production period, hydraulic pump motor works of not stopping work in 24 hours, or frequent in short-term heavy load starting work, and one side causes the waste of the energy, the working life of having reduced electric elements and hydraulic element on the other hand.The hydraulic pump motor of frequent short-term operation causes that the electric motor starting electric current is big, impact device, and energy waste is serious; Oil transportation or short-term operation repeatedly that oil pump does not stop 24 hours every days, the oil mass of oil pump output has only about 20% to be passed to operating cylinder, other about 80% oil mass has all flowed back to fuel tank at a high speed by relief valve, about 80% the oil stream that overflows back fuel tank has all been done idle work and has been converted to heat energy, cause oily temperature rise in the fuel tank, Sealings such as hydraulic system cushion rubber are produced harm, must be equipped with corresponding cooling equipment simultaneously and cool off, the device structure complexity, the user cost height.
Summary of the invention
In order to solve deficiencies such as hydraulic station structure complexity in the prior art, user cost height, energy consumption height, service life of equipment weak point, the invention provides a kind of simple in structure, need not set up cooling equipment, user cost is low, and motor service intermittent, energy consumption are low, the hydraulic station efficient energy-saving device of long service life.
The technological scheme that this gate adopts is: a kind of hydraulic station efficient energy-saving device, the oil pump that comprises control cabinet, hydraulic jack, hydraulic control valve and translator, the oil pump import connects hydraulic oil container, the oil pump outlet connects hydraulic jack through hydraulic control valve, hydraulic control valve all is connected control cabinet with motor, its technical characterstic is also to comprise pressure gauge with electric contact, electromagnetic relief valve, accumulator, one-way valve and intelligent control valve, described intelligent control valve is arranged between oil pump import and the hydraulic oil container, and intelligent control valve connects hydraulic control valve through accumulator; Described oil pump is provided with the little tubule of oil return that is communicated with hydraulic oil container, is provided with one-way valve and pressure gauge with electric contact successively between described oil pump outlet and the hydraulic control valve, and the pipeline between one-way valve and the pressure gauge with electric contact is communicated to fuel tank through electromagnetic relief valve; Described intelligent control valve, pressure gauge with electric contact and electromagnetic relief valve all are connected control cabinet.
Further, be provided with one-way valve between described intelligent control valve and the hydraulic oil container.
Again further, be provided with pressure gauge between described intelligent control valve and the accumulator.
When hydraulic jack must push the work forward, set the high-pressure of pressure gauge with electric contact, the control cabinet starting electrical machinery drives oil pump work, control cabinet control this moment intelligent control valve connects fuel tank and oil pump, electromagnetic relief valve are closed, oil pump suction hydraulic oil is delivered to hydraulic control valve through one-way valve, intelligent control valve, pressure gauge with electric contact, and hydraulic control valve control hydraulic oil promotes hydraulic jack work and controls hydraulic oil simultaneously to the accumulator hydraulic energy-accumulating; When pressure gauge with electric contact reaches the setting height for voltage pressure, control cabinet control motor stops, the connection between control cabinet control hydraulic control valve and accumulator is simultaneously closed, intelligent control valve turn-on accumulator and oil pump import, electromagnetic relief valve unlatching, hydraulic oil in the hydraulic jack is back to hydraulic oil container through hydraulic control valve, electromagnetic relief valve, and accumulator discharges hydraulic oil and is back to hydraulic oil container through intelligent control valve, oil pump, the little tubule of oil return.
Adopt above technological scheme, the beneficial effect that the present invention reaches is: hydraulic station is controlled the pressure stability of whole hydraulic system in the interval that pressure gauge with electric contact is set by this energy-conservation device, control cabinet is controlled the work of oil pump according to the pressure of system.Low when system pressure, when oil mass need be replenished, control cabinet control motor gets electric startup, oil pump does not have inrush current and starts replenishment system pressure, oil mass, oil pump stops when adding to system's pressure maximum.When system pressure, when oil mass arrives lower bound, the automatic once more soft start of oil pump; The accumulator stored energy, intelligent control valve may command system pressure, oil mass are replenished when the pressure oil mass arrives lower bound in the interval that pressure gauge with electric contact is set, and arrive high oil pump in limited time and stop.When accumulator released energy, oil return promoted oil pump and guarantees the incomplete stall of oil pump, and when motor started once more, motor need not inrush current; The hydraulic oil liquid of oil pump output overflows back fuel tank no longer at a high speed and flogs a dead horse, the oil pump acting obtains 100% and all utilizes, the oil that original oil pump overflows back fuel tank accounts for about 80% of the whole oil transportation amounts of oil pump, oil pump and hydraulic element have shortened for about 80% running time, thereby saving power, the working life that can strengthen oil pump and hydraulic element greatly simultaneously; No longer high speed overflow of hydraulic oil, the oil that can reduce hydraulic station is warm, need not be equipped with cooling equipment, reduces user cost, and the working life that has strengthened sealing and hydraulic oil greatly, also can stop the oil impregnate phenomenon, reaches the purpose of hygienic environment-protecting.
The present invention is simple in structure, need not set up cooling equipment, and user cost is low, adopt control cabinet to cooperate intelligent control valve to realize automatic supercharging, no high speed oil return and the unpowered continuous running of oil pump of hydraulic jack, whole energy consumption is low, equipment operation safety, long service life, environmentally safe.
