Technical field
The present invention relates to the attached toolings of current transformer, the specially fluid injection of water cooling current transformer and pumping equipment.
Background technique
The type of cooling of current transformer is divided into: natural cooling, forced air cooling, liquid cooling, Phase cooling.Electric locomotive unsteady flow
Device is cooling using liquid, and every current transformer fills 50~70 liters of coolant liquid.Existing liquid injection industrial installation is a kind of manual form, by pipe
Road, manual pump, quick coupling, hose composition, have a single function, can only carry out fluid injection operation, it is difficult to meet cooling system exclusion
Partially liq or the demand that liquid is discharged, also, low efficiency hand-manipulated, convenience are poor, as production scale expands, increasingly
It is difficult to meet the production requirement that cooling system frequently fills coolant liquid.
Summary of the invention
The present invention solves existing hand liquid injection industrial installation and has a single function, and the problem of low efficiency, convenience difference provides a kind of water
Cold current transformer fluid injection and pumping equipment.
The present invention is achieved by the following technical scheme: the fluid injection of water cooling current transformer and pumping equipment, including by the first mistake
The fluid injection pipeline that filter, the first electric three passes ball valve, water pump, the second electric three passes ball valve, quick coupling are connected in sequence；?
Three-way connection, the third nozzle (first and second of three-way connection are also serially connected between second electric three passes ball valve and quick coupling
Nozzle is connected to fluid injection pipeline) with the third valve port of the first electric three passes ball valve (the first and second valve ports are connected to fluid injection pipeline)
Between be connected with pipe, the third valve port of the second electric three passes ball valve by drain and be connected thereto the drain master for being serially connected with the second filter
Pipe.When needing fluid injection, quick coupling is docked with the liquid injection port of current transformer；Control the first and second electric three passes ball valves first,
The conducting of second valve port, turns on the power switch, is on pump switch, coolant liquid is through first filter, the first electric three passes ball
Valve, water pump, the second electric three passes ball valve, the first and second nozzles of three-way connection, quick coupling enter current transformer；Need drain
When, the leakage fluid dram position of quick coupling and current transformer is constant, second, third valve port conducting of the first electric three passes ball valve of control,
Second electric three passes ball valve first, the conducting of third valve port, change-over switch is opened, is on pump switch, in current transformer
Coolant liquid through quick coupling, the second of three-way connection and third nozzle, pipe by drain, the first electric three passes ball valve third and
Second valve port, water pump, the first of the second electric three passes ball valve and third valve port, the second filter, discharge coolant liquid.
The present invention realizes automatic fluid injection and the row of water cooling current transformer using a water pump by unique circuit design
Liquid, while fluid injection efficiency and operation convenience are improved, the needs of current transformer batch, large-scale production are met, while also full
Draining function when foot maintenance.
