Abstract
The utility model discloses an efficient energy-saving and water-saving hydraulic pressure station which comprises a motor, a high pressure oil pipe, an electromagnetic relief valve, an energy accumulator, a pressure transmitter, a programmable logic controller (PLC) program control cabinet and oil tank elements. The PLC program control cabinet and a zero current converter control the pressure of a whole hydraulic pressure system. The zero current converter controls working state of an oil pump and the motor according to the pressure and oil volume of the system. An oil pressure can be read from a pressure meter. When the system pressure is low, oil volume needs supply, the PLC program control cabinet sends out signals, and under the assistance of the zero current converter, the motor starts without starting current. When the system pressure is complemented to the largest, the motor stops operation with commands of the pressure transmitter. The efficient energy-saving and water-saving hydraulic pressure station has the advantages that the efficient energy-saving and water-saving hydraulic pressure station can not only save a large mount of electric energy, but also maintain oil temperature of the hydraulic pressure station within the most reasonable temperature, strengthens the hydraulic elements, prolongs service life of the hydraulic oil, keeps sanitary and lean of a hydraulic pump station, and enables the hydraulic equipment to achieve the purpose of being safe, energy-saving, water-saving, environment-friendly and reductive in emission.
Description
Technical field
The utility model relates to a kind of hydraulic station temperature control device, especially a kind of new and effective hydraulic station that can energy-saving and water-saving.
Background technique
Original hydraulic station; In order to guarantee the scene of using sufficient pressure source is arranged such as the hydraulic station of steel mill, the running oil transportation of using the driven by motor plunger pump not stop 24 hours every days, pressure oil through relief valve be fed to use on-the-spot; Fluid unnecessary when pressure arrives the upper limit is by relief valve high speed flow oil sump tank; Relief valve cuts out when pressure arrives the lowest limit, and pressurization again comes to stablize on-the-spot working pressure by this way.
In such working procedure; Fluid is all through the relief valve friction work that circulates at a high speed; Cause the oily temperature rise of hydraulic station, just need motor pump to be drawn to cooler to the high temperature hydraulic oil in the fuel tank, cool with water-cooled mode; Guarantee the viscosity of fluid with this, prolong the working life of fluid.
So oil transportation of not stopping 24 hours every days of the oil pump of hydraulic station at present; It is on-the-spot to using that pressure oil is fed to the control valve platform through relief valve, but operating cylinder only account for about 25% of total fuel delivery with oil mass, the oil 75% or more flows and has all flowed back to fuel tank at a high speed through relief valve; The oil stream more than 75% that overflows back fuel tank has all been done idle work; And cause the temperature rise of fuel tank oil, and whole hydraulic system has been caused very big drawback, wasted a large amount of electric energy and water.More serious is, because oily temperature height causes oil vapour pollution, hydraulic oil and Sealing easy ageing, reduces service life of equipment, increases maintenance cost and has increased working strength of workers.
So the requirement that traditional hydraulic station has been difficult to keep pace with the times and the rhythm of production.
The model utility content
The model utility purpose: to the deficiency of existing technology, the exploratory experiment that our process is carried out in places such as steel mills has designed kind efficient energy-saving water-saving hydraulic station.
Technological scheme: in order to realize above-mentioned model utility purpose; The technological scheme that the utility model adopted is: a kind of efficient energy-saving water-saving hydraulic station; Form by motor, high-pressure oil pipe, electromagnetic relief valve, accumulator, pressure transmitter, PLC program control cabinet and fuel tank element; The termination of motor is provided with a plunger pump and no current frequency variator; High-pressure oil pipe connects plunger pump and electromagnetic relief valve, and an end of electromagnetic relief valve is provided with pressure transmitter, and said pressure transmitter front end is provided with a pressure gauge.Through pressure, the flow reasonably stability of PLC program control cabinet and the whole hydraulic system of no current Frequency Converter Control, the working state that the no current frequency variator is controlled oil pump and motor according to the pressure and the oil mass of system, oil pressure can be read by pressure gauge.
Low when system pressure, when oil mass need be replenished, PLC program control cabinet sends signal, motor no inrush current under the help of no current frequency variator starts, replenishment system pressure.When adding to system's pressure maximum, motor shuts down under the instruction of pressure transmitter.
Beneficial effect: the utility model compared with prior art; Its beneficial effect is: 1, not only can practice thrift a large amount of electric energy, and the oil temperature that can control hydraulic station strengthens hydraulic element in rational temperature; Prolong the working life of hydraulic oil, thoroughly eradicate the oil impregnate phenomenon of hydraulic station; 2, the hygiene that keeps hydraulic power unit makes hydraulic equipment reach the purpose of safe, energy-conservation, water saving, environmental emission reduction; 3, under logical PLC control cabinet of package unit and the effect of no current frequency variator, intermittent running has shortened a large amount of hydraulic station operating times every day; This device is local on probation at the iron works 2# of Hong Xing joint-stock company of wine steel group blast furnace etc. on August 13rd, 2010, facts have proved, use this device after; Motor is changed into and is worked four to five hours every day by the commentaries on classics of not stopping transport of original twenty four hours, economize on electricity 50% to 80%; Stop using the water cooling recycle pump, conserve water resource 100%.
