Brief description of the drawings
Fig. 1 is the experimental rig partial schematic sectional view of the present invention.
In figure：Test stand 1, water tank 2, water pump 3, intake pipe 4, regulating valve 5, compressed air rubber hose 6, articulation 7, plug
Door 8, snap joint 9, screen pack check-valves 10, castor 11, handle 12.
Embodiment
The present invention is further described below with reference to specific embodiment：
Referring to Fig. 1, the present invention provides fixed on a kind of railcar rain test device, including test stand 1, test stand 1 connect
It is connected to be welded with iron plate, iron plate on water tank 2, water tank 2 and is fixedly installed water pump 3, the import of water pump 3 is connected with intake pipe 4, takes
The one end of water pipe 4 away from water pump 3 is stretched into water tank 2, the outlet of water pump 3 is connected with the water inlet of regulating valve 5, and regulating valve 5 goes out
The mouth of a river is connected with compressed air rubber hose 6, the one end of compressed air rubber hose 6 away from regulating valve 5 along away from regulation
The direction of valve 5 is connected with articulation 7, cock 8, snap joint 9 in turn., can be with adding technology in water tank 2 in practical operation
Required antirust solution, the caliber for determining connecting water pipe is φ 20mm, and regulation pressure is to not less than 0.2MPa, to meet railcar car
Whole technological requirements that ceiling portion salt fog test is checked, it is easy to operate, it is practical.
As a further improvement on the present invention, intake pipe 4, which is stretched on one end of water tank, is fixedly connected with screen pack check-valves
10.So it is to ensure in water tank 2 that debris is not drawn into water pump 3 to prevent water pump 3 from dallying cause thermal damage, and filter check valve 10
It can ensure that water (flow) direction will not be passed back into water tank 2 in system, prevent water pump 3 from damaging.
As a further improvement on the present invention, it is welded with water tank 2 on test stand 1.Water tank 2 can be improved by the way of welding
With the stability being fixed on experimental rig, prevent the wheel rotation in the course of work of the charging pump 3 of water tank 2 from driving water pump 3 to shake
Move and cause the factors such as the change in location of water tank 2, change in shape, reduce the reliability of experimental rig.
As a further improvement on the present invention, the bottom of test stand 1 is fixedly connected with castor 11, and castor 11 is provided with 4, Gu
Surely it is connected to the bottom at four angles of test stand 1.Because workshop platform interdigit span is larger, for convenience of movement and the experiment people of device
