Abstract
A kind of diesel locomotive transmission oil heatexchanger pressure device, belong to diesel locomotive maintenance of equipment technical field, for being suppressed to diesel locomotive transmission oil heatexchanger.Its technical scheme is：It is a kind of annular end cap flange, there is connecting screw hole on the annulus of end cap flange, the position of connecting screw hole is corresponding with the installation screw position of heat exchanger barrel body end cover, the flange diameter of bore of end cap flange and the excircle diameter of the copper pipe end face of heat exchanger match, and the flange inner hole sleeve of end cap flange is on the copper pipe angle head cylindrical week of heat exchanger.The utility model instead of end cap when carrying out suppressing detection with two annular end cap flanges, and end cap flange is connected with cylinder, and the copper pipe end face of cylinder can find out seepage place exactly in the flange endoporus of the end cap flange of annular.The utility model is simple in construction, easy to use, thoroughly solves the drawbacks of end cap covers copper pipe end when heat exchanger suppresses maintenance, substantially increases inspection speed and repair quality.
Description
Technical field
A kind of device suppressed to diesel locomotive transmission oil heatexchanger is the utility model is related to, belongs to diesel locomotive
Maintenance of equipment technical field.
Background technology
GK1C locomotives are that the characteristic that the power of diesel engine is needed by hydraulic transmission gear box according to locomotive is carried out into power output,
In the course of the work, transmission oil heatexchanger cools to the working oil of transmission case, is crossed outside pipe and water is crossed in oil pipe, pass through water
The heat that tape loop goes rancid reaches cooling purpose.With the growth of the locomotive time limit and the corrosion of water, the copper pipe of heat exchanger can go out
Existing Seepage, causes motorcycle oil-water to mix, influences locomotive normal operation, it is necessary to be repaired in time.At present in working oil heat
Replacement o circle, bulge test after assembling are wanted in exchanger maintenance, qualified rear entrucking uses.But present in service work
Problem is：Heat exchanger outward appearance is tubular, and the main body in cylinder is made up of copper pipe and end plate, and cylinder one end is by flange by end plate and heat
Exchanger cylinder connects, and the other end of cylinder is to be connected by the end cap leaked water with cylinder, no flange apparatus, is suppressed to cylinder
When, there is one end of end cap because being blocked by end cap, the end copper pipe seepage is invisible, have impact on maintenance effect so that find out
The copper pipe of permeability is extremely difficult.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of diesel locomotive transmission oil heatexchanger pressure device,
This pressure device can expose the copper pipe of connection end after being connected with heat exchanger cylinder, can clearly be observed that and ooze
The copper pipe of leakage, enables to suppress work and quickly smoothly carries out, and ensures the quality of maintenance.
Solve above-mentioned technical problem technical scheme be：
A kind of diesel locomotive transmission oil heatexchanger pressure device, it is a kind of annular end cap flange, end cap flange
There is connecting screw hole on annulus, the position of connecting screw hole is corresponding with the installation screw position of heat exchanger barrel body end cover, end cap method
Blue flange diameter of bore and the excircle diameter of the copper pipe end face of heat exchanger match, and the flange inner hole sleeve of end cap flange exists
On the copper pipe angle head cylindrical week of heat exchanger.
Above-mentioned diesel locomotive transmission oil heatexchanger pressure device, the end cap flange are two, and they are placed side by side, point
It is not relative with two cylinders of heat exchanger, there is vertical breach on the annulus of the relative junction of two end cap flanges respectively, two
The vertical indentation, there of individual end cap flange is relative.
The beneficial effects of the utility model are：
The utility model instead of end cap, end cap flange and cylinder when carrying out suppressing detection with two annular end cap flanges
Body connects, and cylinder is fixed, so as to be suppressed；Because the copper pipe end face of cylinder is exposed to the method for the end cap flange of annular
In blue endoporus, if seepage, copper pipe end has liquid and oozed out, it is seen that, very intuitively, can look for exactly at a glance
Go out seepage place, handled in time.
The utility model is simple in construction, easy to use, thoroughly solves diesel locomotive transmission oil heatexchanger and suppresses maintenance
When end cap masking copper pipe end the drawbacks of, substantially increase inspection speed and repair quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state diagram of the present utility model.
Marked in figure as follows：End cap flange 1, connecting screw hole 2, flange endoporus 3, vertical breach 4, cylinder 5, copper pipe end face 6,
Copper pipe 7.
Embodiment
The utility model is a kind of annular end cap flange 1.
Show there is connecting screw hole 2, the position of connecting screw hole and heat exchanger on the annulus of annular end cap flange 1 in figure
The installation screw position of barrel body end cover is corresponding, is fixedly connected so that end cap flange 1 can substitute end cap with cylinder 5.
Shown in figure, the diameter of flange endoporus 3 of end cap flange 1 and the excircle diameter phase of the copper pipe end face 6 of heat exchanger
Matching, the flange endoporus 3 of end cap flange 1 are enclosed on the excircle of copper pipe end face 6 of heat exchanger.The copper pipe end of cylinder 5 can be made
Face 6 is in the flange endoporus 3 of the end cap flange 1 of annular, and if seepage, the port of seepage copper pipe 7 has liquid and oozed out, and one
Eye it is seen that, very intuitively, seepage place can be found out exactly, handled in time.
Shown in figure, in actual use, end cap flange 1 is two, and they are placed side by side, respectively with the two of heat exchanger
Individual cylinder 5 is relative, there is vertical breach 4 on the annulus of the relative junction of two end cap flanges 1 respectively, two end cap flanges 1
Relative at vertical breach 4, when avoiding two connections of end cap flanges 1, opposite site has lap to influence connection.
One embodiment of the present utility model is as follows：
No. 258 diesel locomotive transmission oil heatexchangers of certain enterprise are pulled down cylinder 5 from locomotive and beaten there occurs profit seepage
During pressure, pressure no longer declines from seven kilograms to four kilograms, in appearance oil circuit ne-leakage, water route also ne-leakage, only profit seepage,
Therefore judge that copper pipe and end plate have leakage, between end cap flange 1 and cylinder 5 good O-ring will be added to fasten after taking heat exchanger apart
It is good, then cylinder 5 is suppressed again, finds there is a leak of copper pipe 7 after suppressing, scene is handled, after processing again
Suppressed, worked well, then overall package is suppressed seepage does not occur again, ensure that the quality after maintenance.
