Technical field
The utility model relates to a kind of simulation locomotive traction motor vent flow and pressure test device, and it is the device of the test various traction electric machines of railway electric locomotive actual ventilation state on locomotive.
Background technology
Modern electric locomotive traction motor ventilating system adopts the car body draft type; (negative pressure is about 100～200Pa) in the general locomotive to utilize the traction blower fan to produce negative pressure at the air intake oral-lateral; The locomotive outer air is sucked in the car through side wall filtrator and window shutter (2); Be inhaled into traction blower fan (5) then,, flow to traction electric machine (9) through air channel and light air road (7) and make the traction electric machine cooling again by the pressurization of traction blower fan.
Present electric locomotive traction motor some problems below actual ventilation state has on locomotive: one, it is (generally to be about 1.8m through the compressor flow data that obtained behind the traction blower fan routine tests
3About/s) and blower pressure data (generally being about about 5000Pa).Two, because getting into the arrival traction electric machine from air intake, cooling air passed through five parts; The size and the shape of each parts have nothing in common with each other; The resistance that is produced is also different, also just has very big error so finally flow to flow and blast and the Theoretical Calculation of the cooling air of traction electric machine.Three, receive structural limitations,, just can not detect flow and the blast of the cooling air of traction electric machine again in case each parts installs.Traction electric machine can not get the flow and the blast of enough cooling airs in sum, finally causes the traction electric machine too high insulating property that influence traction electric machine of generating heat, and causes traction electric machine scaling loss generation machine broken, causes heavy economic losses to locomotive operation.Perhaps, cause production cost too high, produce unnecessary waste because the flow and the blast parameter designing of cooling air are too high.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and a kind of simulation locomotive traction motor vent flow and pressure test device are provided; It is before traction electric machine comes into operation, just the flow and the blast of the cooling air that finally flows to traction electric machine to be carried out simulation test, makes the design of traction electric machine ventilating system and manufacturing cost be in optimum condition, guarantees the traction electric machine safe operation.
The technical scheme of the utility model is: a kind of simulation locomotive traction motor vent flow and pressure test device, comprise air inlet, window shutter, intake stack, traction blower fan, traction blower fan mount pad, traction electric machine, and it is characterized in that:
Be provided with air inlet in described simulation locomotive traction motor vent flow and the pressure test device and measure air channel, light air road, air outlet measurement air channel, traction electric machine installation and moving dolly, damper and measuring table, above-mentioned each parts are according to locomotive actual installation mode connection to be installed;
Described air inlet is measured the air channel and is arranged between intake stack and the traction blower fan, and this air inlet is measured the air channel and is provided with six pressure survey nozzles and six wind quantity test holes;
Described light air road and air outlet are measured the air channel and are arranged between traction blower fan and the traction electric machine, and ` is that two ends, light air road are communicated with outlet of traction blower fan and air outlet measurement air channel import respectively, and air outlet is measured ducting outlet and is connected with traction electric machine; This air outlet is measured the air channel and is provided with six pressure survey nozzles and six wind quantity test holes;
It is the measuring wind speed appearance to be inserted respectively note six data in six measured holes and calculate mean wind speed according to formula again that described air inlet is measured air channel and air outlet measurement air channel one
Wherein, the ventilation total area is: S
0=_ _ _ _ _ _ m
2Calculate air quantity at last:
The 2nd, pressure-measuring device is connected to respectively on six gaging nozzles calculates mean pressure P again;
Described damper is one and regulates the flow of cooling air and the porous plate of blast that this damper is arranged on traction electric machine cooling air channel endpiece; Described damper is a porous plate, the one, and the measuring wind speed appearance inserted in the measured hole note wind speed V, the 2nd, pressure-measuring device is connected to notes pressure P on the gaging nozzle, the adjusting that how much reaches air quantity and pressure of the quantity through adjustment hole;
Described traction electric machine installation and moving dolly is to connect to form through adjusting screw(rod) and setting nut by wheeled framework and traction electric machine mounting platform, and this traction electric machine installation and moving dolly is to move under the measuring table.This traction electric machine is installed and travelling car is for the traction electric machine with about three tons of weight moves under the measuring table, also has a up-down adjustment device on the dolly, so just can satisfy the installation needs of the traction electric machine of different model, different size.
Described traction blower fan ventilating system proving installation for this reason provides wind regime and is provided with, and it makes the locomotive outer air through the pressurization of traction blower fan, through air channel and light air road, flows to traction electric machine, makes the traction electric machine cooling.
Described measuring table is a platform of building for the installation needs of the traction electric machine that satisfies different model, different size, can also make things convenient for the tester to measure and respectively organize data.
The innovative point of the utility model is: one, it is that the data on flows and the pressure data that are obtained through simulation locomotive traction motor actual installation mode installation testing are truly error free.Two, passed through five parts because cooling air gets into the arrival traction electric machine from air intake, the size and the shape of each parts have nothing in common with each other, and the resistance that is produced is also different, and this system can measure the flow and the pressure loss of each parts.Three, it not only can detect the traction electric machine of different model, different size but also not receive structural limitations, in case each parts installs, can also increase and reduce flow and blast that parts detect the cooling air of traction electric machine.Traction electric machine can obtain the flow and the pressure of enough cooling airs in sum, and reduce production cost the serviceable life that prolongs traction electric machine, produces better economic benefit.
