Abstract
The utility model relates to a hydraulic energy-saving pump device of a hydraulic pump station, which includes an energy accumulator, an electric check valve, a throttle valve, a pump body and a motor main body, wherein the motor main body is connected with the pump body; an external oil circuit of the pump body is sequentially connected with the throttle valve, the electric check valve and the energy accumulator; and the energy accumulator is externally equipped with a pressure gage with an electric contact. The utility model has the benefits that the hydraulic energy-saving pump device not only can serve as an oil pump, but also can be switched to a hydraulic motor working mode, when the oil pump motor is restarted, pressure oil in the energy accumulator is released to the hydraulic pump/ the hydraulic motor through the throttle valve, so as to drive the motor to quickly start, the motor is electrified as long as the motor reaches a certain rotating speed, and then as the motor is started at a high rotating speed, the starting current is reduced and the energy is saved.
Description
Technical field
The utility model relates to hydraulic package, relates in particular to a kind of hydraulic energy-saving pump-unit of hydraulic power unit.
Background technique
Oil hydraulic pump is a kind of hydraulic element that pressurized liquid is provided for hydraulic transmission, belongs to a kind of of pump.Its function is the pressure energy that the mechanical energy of power engine (as motor and internal-combustion engine etc.) is converted to liquid.Its working principle is the variation that motion brings pump chamber, thereby compressed fluid makes fluid have the pressure energy.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 utility model provides a kind of 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 utility model 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 described in the utility model 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 utility model 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 utility model embodiment.
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 utility model embodiment, 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.
