A kind of salt mist environment device that is used for experiment on fatigue propertiesTechnical field
The utility model belongs to the experiment on fatigue properties technology, relates to a kind of salt mist environment device that is used for Fatigue Cracking Test under the salt air corrosion condition.
Background technology
For the fatigue break performance of test engine disc under the salt air corrosion condition, need be used for the salt mist environment device of Fatigue Cracking Test, present domestic this kind equipment that also do not have.Though this kind equipment is abroad arranged, and device is complicated, cost height, Operation and Maintenance inconvenience.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, cost is low, the salt mist environment device that is used for experiment on fatigue properties of convenient operating maintenance.
The technical solution of the utility model is: a kind of salt mist environment device that is used for experiment on fatigue properties, the upper grip and the lower chuck that comprise the experiment on fatigue properties machine, underproof sample is clamped between upper grip and the lower chuck, it is characterized in that, an environmental cabinet and a salt fog feed mechanism are arranged; Environmental cabinet is a closed box that is fixed on the experiment on fatigue properties machine, upper grip puts in the closed box from the top of environmental cabinet, between the tank wall of upper grip and environmental cabinet, sealing mechanism is arranged, lower chuck puts in the closed box from the below of environmental cabinet, between the tank wall of lower chuck and environmental cabinet sealing mechanism is arranged, at the bottom of the case of environmental cabinet leakage fluid dram is arranged, this leakage fluid dram is communicated with catch box by discharging tube, on the tank wall of the side of environmental cabinet shower nozzle is arranged, the spout of shower nozzle is towards underproof sample; The salt fog feed mechanism is made up of woven hose, hydrocone type thrower, air flow rate adjustment valve, air pump and liquid reserve tank; One end of woven hose is communicated with shower nozzle, the other end of woven hose is communicated with the output port of hydrocone type thrower, the air-in of hydrocone type thrower is communicated with the delivery outlet of air flow rate adjustment valve by pipeline, the input port of air flow rate adjustment valve is communicated with the delivery outlet of air pump by pipeline, the liquid inlet of hydrocone type thrower is communicated with liquid reserve tank by U trap, and the liquid level of the salt fog liquid that stores in the liquid reserve tank is higher than siphonal liquid sucting port.
The utility model has the advantages that: simple in structure, cost is low, and convenient operating maintenance has solved the needs that carry out experiment on fatigue properties under the salt mist environment in the new work engine development.

Embodiment
Below the utility model is described in further details.Referring to Fig. 1, a kind of salt mist environment device that is used for experiment on fatigue properties comprises the upper grip 1 and thelower chuck 2 of experiment on fatigue properties machine, andunderproof sample 12 is clamped between upper grip 1 and thelower chuck 2, it is characterized in that anenvironmental cabinet 3 and a salt fog feed mechanism are arranged;Environmental cabinet 3 is closed boxes that are fixed on the experiment on fatigue properties machine, upper grip 1 puts in the closed box from the top ofenvironmental cabinet 3, between the tank wall of upper grip 1 andenvironmental cabinet 3, sealing mechanism 1a is arranged,lower chuck 2 puts in the closed box from the below ofenvironmental cabinet 3, between the tank wall oflower chuck 2 andenvironmental cabinet 3, sealing mechanism 1a is arranged,leakage fluid dram 1b is arranged at the bottom of the case ofenvironmental cabinet 3, thisleakage fluid dram 1b is communicated withcatch box 4 bydischarging tube 5, on the tank wall of the side ofenvironmental cabinet 3shower nozzle 6 is arranged, the spout ofshower nozzle 6 is towardsunderproof sample 12; The salt fog feed mechanism is made up of woven hose 7,hydrocone type thrower 8, air flowrate adjustment valve 9,air pump 10 andliquid reserve tank 11; One end of woven hose 7 is communicated withshower nozzle 6, the other end of woven hose 7 is communicated with the output port ofhydrocone type thrower 8, the air-in ofhydrocone type thrower 8 is communicated with by the delivery outlet of pipeline with air flowrate adjustment valve 9, the input port of air flowrate adjustment valve 9 is communicated with by the delivery outlet of pipeline withair pump 10, the liquid inlet ofhydrocone type thrower 8 is communicated withliquid reserve tank 11 byU trap 13, and the liquid level of the salt fog liquid that stores in theliquid reserve tank 11 is higher than the liquid sucting port ofU trap 13.
Principle of work of the present utility model is: the salt solution that the utilization siphon principle will store up certain proportion concentration in the case at night is transferred to environmental cabinet and is injected into vaporific by the salt fog feed mechanism, fatigue sample in the environmental cabinet is worked in reach test objective in the salt fog, and the big I of salt fog is regulated the fog size by air flow rate adjustment valve.
Among the embodiment of the present utility model,hydrocone type thrower 8, air flowrate adjustment valve 9 andair pump 10 all are finished parts.
