Description

Two-way oil transportation machine
Technical field
This utility model relates to a kind of two-way oil transportation machine.
Background technology
Load ratio bridging switch is the core component that transformator completes pressure regulation, is the most frequent assembly of transformer operating, and the maintenance to load ratio bridging switch is main transformer maintenance important component part, if the repair time is long, main transformer power off time will be extended, reduce transformator availability coefficient, reduce power supply reliability.According to the first index request of wound in 2014, transformator availability coefficient to reach 99.975%, and this just requires, under the premise ensureing work quality, to compress the main transformer interruption maintenance working time, improves service work efficiency.
According to working experience, when on-load tap switch maintenance operation accounts for more: the suspended core of shunting switch and internal overhaul are safeguarded, oil extraction and cleaning, and oiling, wherein the suspended core of shunting switch and internal overhaul safeguard that the shared time is 33.4%, but the suspended core of load ratio bridging switch and internal overhaul safeguard that the required time is rigidity, the spatiality that can promote is little, and oil extraction and to clean the shared time be 38.07%, time shared by oiling is 10.15%, these two flow process times of accounting for altogether are 48.22%, oil within load ratio bridging switch is also few, and arrange oiling and cleaning takes the so long time, obviously unreasonable.It has been investigated that, causing row's filling pump equipment that the main cause of the problems referred to above is currently used is be all unidirectional, does not possess two-way oil transportation function, and each oiling or oil extraction all there is a need to exchange oil fuel tube and oil exit pipe, therefore consuming time longer.
Utility model content
The purpose of this utility model is in that for drawbacks described above of the prior art, it is provided that a kind of rational in infrastructure, easy and simple to handle, possesses the two-way oil transportation machine of two-way oil transportation function.
For realizing above-mentioned utility model purpose, this utility model adopts the technical scheme that a kind of two-way oil transportation machine, it includes the oil pump, the first entry/exit hydraulic fluid port and the second entry/exit hydraulic fluid port that are interconnected by petroleum pipeline, and wherein, described oil pump has inlet side mouth and goes out port;It is provided with the first inlet valve between described first entry/exit hydraulic fluid port and the inlet side mouth of oil pump, and going out of oil pump is provided with the first delivery valve between port;It is provided with the second inlet valve between described second entry/exit hydraulic fluid port and the inlet side mouth of oil pump, and going out of oil pump is provided with the second delivery valve between port.
Additionally, this utility model also provides for following attached technical scheme:
It is provided with filter before the inlet side mouth of described oil pump.
Described first entry/exit hydraulic fluid port and the second entry/exit hydraulic fluid port are connected to quick connecting pipe.
Compared to prior art, advantage of the present utility model is in that: disclose a kind of two-way oil transportation machine, this two-way oil transportation owner to include oil pump, first entry/exit hydraulic fluid port, second entry/exit hydraulic fluid port, first inlet valve, second inlet valve, first delivery valve, and second delivery valve, rational in infrastructure, by controlling aforementioned four valve, first entry/exit hydraulic fluid port and the second entry/exit hydraulic fluid port can realize oil-feed and fuel-displaced switching, easy and simple to handle, possesses two-way oil transportation function, eliminate each oiling or oil extraction in prior art and all there is a need to exchange the work of oil fuel tube and oil exit pipe, repair time has been greatly shortened, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of two-way oil transportation machine of the present utility model.
Fig. 2 is the structural representation of two-way oil transportation machine of the present utility model.
Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Two-way oil transportation machine of the present utility model is mainly used in transformer overhaul, and on-load tap switch maintenance and daily oil strain etc. relate to transformer oil service work.Seeing figures.1.and.2, two-way oil transportation owner to include oil pump the 10, first entry/exit hydraulic fluid port the 1, second entry/exit hydraulic fluid port the 2, first inlet valve the 11, second inlet valve the 12, first delivery valve 21 and the second delivery valve 22 that are interconnected by petroleum pipeline 100.Oil pump 10 is power source, and it has entrance point 10a and port of export 10b, is provided with filter 15 before entrance point 10, for transformer oil is filtered cleaning.First entry/exit hydraulic fluid port 1 and the second entry/exit hydraulic fluid port 2 are used equally to oil-feed and fuel-displaced.First inlet valve 11 is arranged between the first entry/exit hydraulic fluid port 1 and the entrance point 10a of oil pump 10, and the first delivery valve 21 is arranged between the first entry/exit hydraulic fluid port 1 and the port of export 10b of oil pump 10;Second inlet valve 12 is arranged between the second entry/exit hydraulic fluid port 2 and the entrance point 10a of oil pump 10, and the second delivery valve 22 is arranged between the second entry/exit hydraulic fluid port 2 and the port of export 10b of oil pump 10;Aforementioned four valve is provided with opening and closing function, and when the valve is closed, the pipeline at its place is blocked.
The caliber of the petroleum pipeline 100 of the two-way oil transportation machine of the present embodiment is 30 millimeters, solve should meet flow, lift technology requires to consider again the caliber preferentially problem of economy.
