Abstract
The invention relates to a hydraulic energy-saving pump device of a hydraulic pump station, which comprises an energy accumulator, an electric one-way valve, a throttling valve, a pump body and a motor main body, wherein the motor main body is connected with the pump body, an external oil path of the pump body is sequentially connected with the throttling valve, the electric one-way valve and the energy accumulator, and the energy accumulator is externally provided with an electro connecting pressure gauge. The invention has the advantages that the hydraulic energy-saving pump device is used as an oil pump and is also capable of being switched into a work mode of the hydraulic motor, when an oil pump motor is restarted, pressure oil in the energy accumulator is released to a hydraulic pump/hydraulic motor through the throttling valve so as to drive the motor to be rapidly started, and when reaching a certain rotating speed and then being electrified, the motor is started at high rotating speed, therefore, starting current is reduced and purpose of saving energy is achieved.
Description
Technical field
The present invention relates to the hydraulics field, relate in particular to a kind of hydraulic energy-saving pump-unit of hydraulic power unit.
Background technique
In hydraulic system, run into relief valve off-load constantly through regular meeting, pressurizing circulation, or the power failure machine, open situation such as motor cycle, though the relief valve off-load can reduce motor load, but still to consume the similar fully loaded electric energy more than 1/3; Though the power failure machine is consumed power not, when motor starts once more, can consume the very big electrokinetic energy that rises, Fraquent start is often the time, this waste meeting is very big, and electric current constantly impacts electrical network and causes line voltage moment decline greatly, can have influence on the safety and the life-span of other electrical equipment; Also have a lot of big motors in order to overcome these shortcomings, add the reduced voltage starting cabinet, but this only to be part reduced this infringement, and increased equipment cost.
Summary of the invention
At above defective, the invention provides and a kind ofly not only can work as that oil pump uses but also the hydraulic energy-saving pump-unit of changeable hydraulic power unit as the oil hydraulic motor mode of operation, to solve many deficiencies of prior art.
For achieving the above object, the present invention is by the following technical solutions:
A kind of hydraulic energy-saving pump-unit of hydraulic power unit, comprise accumulator, electronic one-way valve, throttle valve, the pump housing, motor main body, described motor main body connects the pump housing, and the outside oil circuit of this pump housing connects throttle valve, electronic one-way valve and accumulator successively, and described accumulator outside is furnished with pressure gauge with electric contact.
The beneficial effect of the hydraulic energy-saving pump-unit of hydraulic power unit of the present invention is: make it not only can work as that oil pump uses but also changeablely be the oil hydraulic motor mode of operation, when Oil pump electrical machinery prestart once more, pressure oil in the accumulator discharges to oil hydraulic pump/oil hydraulic motor by throttle valve, thereby drive motor quick starting together, after motor reaches certain rotating speed, give electrical power again, start under high rotating speed because of motor this moment, thereby reduced starting current, reached purpose of energy saving.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the hydraulic energy-saving pump-unit principle assumption diagram of the described hydraulic power unit of the embodiment of the invention.
Among the figure:
1, accumulator; 2, electronic one-way valve; 3, throttle valve; 4, the pump housing; 5, motor main body; 6, one-way valve; 7, pressure gauge with electric contact; 8, fuel tank; 9, level meter.
Embodiment
As shown in Figure 1, the hydraulic energy-saving pump-unit of the described hydraulic power unit of the embodiment of the invention, comprise accumulator 1, electronic one-way valve 2, throttle valve 3, the pump housing 4, motor main body 5, described motor main body 5 connects motor/pump body 4, and the pump housing 4 outside oil circuits wherein connect throttle valve 3, electronic one-way valve 2 and accumulator 1 successively; Described accumulator 1 outside is furnished with pressure gauge with electric contact 7, the described pump housing 4 outsides one-way valve 6 that is connected in series, and this one-way valve 6 connects the fuel tank 8 that has level meter 9.During work, be full of hydraulic oil (under the upper limit of pressure gauge with electric contact 7 is set) in its accumulator 1 of CTU hydraulic power unit of normal operation, prestart once more after its motor is shut down, electronic one-way valve 2 energisings are opened, but the pressure oil in the accumulator enters the oil hydraulic motor/hydraulic pump body 4 of dual-mode of operation through electronic one-way valve 2 and pre-set throttle valve 3, thereby the drive pump housing 4 and motor main body 5 fast turn-around are together got up, when pressure gauge with electric contact 7 reaches lower limit set value, the electrical power starting enters normal mode of operation; Motor has reduced the big electric current of starting owing to start under high rotating speed, saved electric energy.
