Abstract
The utility model discloses a sand-dust and humidity testing stand for an air braking system. The dust and humidity testing stand comprises a seal box, a sand-dust spraying device, and a humidity control device. The air braking system is placed inside the seal box. The sand-dust spraying device comprises a sand inlet pipe communicated with the seal box, a sand container, and a dust concentration sensor arranged inside the seal box. The sand inlet pipe is communicated with an external wind source through a control valve. A discharge port of the sand container is connected with the sand inlet pipe through a control valve. The humidity control device comprises a liquid inlet pipe communicated with the seal box, a humidifier arranged on the liquid inlet pipe, and a temperature and humidity sensor arranged inside the seal box. The liquid inlet pipe is communicated with an external water source. The humidifier is connected with a PLC. Through the sand-dust spraying device and the humidity control device, the sand-dust and humidity testing stand simulates, inside the seal box, the working state of the whole-set air braking system in the sand-dust environment and within a certain humidity range, thereby realizing the objective of verifying the reliability and the stability of the air braking system.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
as illustrated in fig. 1 and 2, a kind of Pneumatic brake systems sand and dust humidity testing table, comprise seal box 1, dirt device and humidity conditioner sandblast, Pneumatic brake systems is placed in described seal box 1, the described dirt device that sandblasts comprises the sand inlet tube 2 that is communicated with seal box 1, fill husky container 3 and be arranged on the interior sensor of dust concentration 4 of seal box 1, described sand inlet tube 2 is communicated with outside wind regime by solenoid valve 11, the discharging opening of the husky container 3 of described dress is communicated with sand inlet tube 2 by electrical ball valve 12, described humidity conditioner comprises the feed tube 5 that is communicated with seal box 1, be arranged on the humidifier 6 on feed tube 5 and be arranged on the interior wet temperature sensor 7 of seal box 1, described feed tube 5 is communicated with external water source, described humidifier 6 is connected with the wet temp controller with PLC13 respectively and is connected.
Wherein, described seal box 1 top is communicated with seal box 1 bottom by circulation airduct 9, is provided with suction blower fan 10 on described circulation airduct 9.The suction blower fan can guarantee that in seal box, dust can fast moving circulate, and satisfies testing requirements.
Principle of work of the present utility model: the valve class of various Pneumatic brake systems is arranged on the valve installing plate that is arranged in seal box, sandblast dirt device and humidity conditioner simulates duty in Sand Dust Environment and certain humidity range, the reliability and stability of checking Pneumatic brake systems in seal box.
As shown in Figure 1, when dust concentration is inadequate in sensor of dust concentration detects seal box, send signal to control system, control system controls solenoid valve and electrical ball valve is opened simultaneously, injects dust in seal box; When in seal box, dust concentration reached testing requirements, control system was controlled solenoid valve and electrical ball valve is closed, so circulation.
As shown in Figure 2, during test, the wet temp controller will be tested wet temp and set, and simultaneously same wet temp will be set also in touch-screen, and whole like this control system data are united.During test, when relative humidity did not reach requirement of experiment in wet temperature sensor detects seal box, PLC sent signal by the charged work of humidifier, and when reaching testing requirements, time-delay a period of time, humidifier quits work, so periodic duty.
