The solution supplementing device of the cyclic immersion corrosion test comprises a test tank, a solution storage tank, a pump, a solution supplementing tank, a solution supplementing pipe and sealing pipe. One end of the solution supplementing pipe is connected with the bottom of the solution supplementing tank, and the other end is extended to the bottom of a test tank. One end of the sealing pipe is connected with the top of the solution supplementing tank and the other end is extended to the test tank, and a port of the sealing pipe is parallel and level with the required lowest liquid level of the test tank. The solution supplementing tank is in series connection with the pump and the solution storage tank via a liquid transporting pipe, the liquid transporting pipe for connecting the pump and the solution supplementing tank is equipped with an inlet valve, and the solution supplementing pipe is equipped with an outlet valve. The solution supplementing device of the cyclic immersion corrosion test of the utility model utilizes the atmospheric pressure balance to control the liquid level of the test tank, utilizes the solution supplementing pipe to supplement the solution in the test tank, and utilizes the liquid transporting pipe to supplement the solution in the solution supplementing tank, thereby being low in use cost, being safe and reliable and being able to realize the full-automatic operation.
Description
Technical field
The utility model relates to and a kind of week soaks the corrosion test liquid supply device.
Background technology
Corrosion test often the time longer, and most under higher temperature, carry out, the solution evaporation capacity is larger.For keeping testing liquid that one fixing liquid level is arranged, will constantly fill into new solution.As cycle wheel soaks corrosion test, iron mark TB/T2375 regulation, in chamber, air themperature is 45 ℃, the specimen surface temperature 70 C, solution evaporation is very serious, requires constantly to fill into new soln.
Supplementary new soln adopts fluid infusion system more.Now mainly adopt in two ways: a kind of is to adopt the electronic circuit control mode, this class fluid infusion system over-borrowing helps liquid level sensor and solenoid valve to carry out liquid level control, its advantage is that the supplementary precision of solution is high, the fluid infusion process can realize the automatic control under computer management, but, in harsh corrosion test environment, its shortcoming is also more outstanding, be that liquid level sensor, solenoid valve are easily malfunctioning, often cause controlling unsuccessfully, in addition, use cost is too high; Another kind is to utilize atmospheric pressure, by pressure equilibrium, carries out liquid level control, although safe and reliable, use cost is low, and the necessary manually-operated of fluid infusion process, can not realize fully automatically controlling.
Summary of the invention
The purpose of this utility model is to overcome the prior art defect, provides a kind of week to soak the corrosion test liquid supply device.
The technical solution of the utility model is achieved in that soaks the corrosion test liquid supply device in a kind of week, comprise test flume, hopper and pump, it is: also comprise fluid infusion groove and liquid supplementation pipe, sealed tube, liquid supplementation pipe one end is connected with the fluid infusion trench bottom, and the other end stretches into the test flume bottom; Sealed tube one end is connected with fluid infusion groove top, and the other end stretches into test flume and port is concordant with the test flume minimum level of requirement, and fluid infusion groove and pump and hopper are contacted by woven hose.
Preferably, on the woven hose be connected with the fluid infusion groove at pump, be equipped with inlet valve, be equipped with outlet valve on liquid supplementation pipe.
The utility model utilizes atmospheric pressure Force balance control test flume liquid level, utilizes liquid supplementation pipe complementary testing groove solution, utilizes woven hose to supplement fluid infusion groove solution, and use cost is low, safe and reliable, and can realize full-automatic operation.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, the 1-test flume; The 2-hopper; 3-fluid infusion groove; The 4-liquid supplementation pipe; The 5-sealed tube; The 6-inlet valve; The 7-outlet valve; The 8-pump; The 9-woven hose.
Embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, a kind of week is soaked the corrosion test liquid supply device, comprises test flume 1, hopper 2 and pump 8, also comprises fluid infusion groove 3 and liquid supplementation pipe 4, sealed tube 5, and liquid supplementation pipe 4 one ends are connected with fluid infusion groove 3 bottoms, and the other end stretches into test flume 1 bottom; Sealed tube 5 one ends are connected with fluid infusion groove 3 tops, the other end stretches into test flume 1 and port is concordant with test flume 1 minimum level of requirement, fluid infusion groove 3 is contacted by woven hose 9 with pump 8 and hopper 2, be equipped with inlet valve 6 on the woven hose 9 be connected with fluid infusion groove 3 at pump 8, be equipped with outlet valve 7 on liquid supplementation pipe 4.
After testing liquid volatilization in test flume 1, the liquid level of testing liquid descends, break away from liquid level with the end opening of the adjacent sealed tube 5 of testing liquid liquid level, air enters in airtight fluid infusion groove 3 by the end opening of sealed tube 5, under the effect of liquid level difference, testing liquid in fluid infusion groove 3 successively flows into test flume 1 by outlet valve 7, liquid supplementation pipe 4, and the liquid level of testing liquid rises, and reaches the purpose of complementary testing solution.When testing liquid rises to certain altitude, the end opening of sealed tube 5 can be again be sealed by test solution, and the blocking-up air enters into the passage of fluid infusion groove 3, and when the atmospheric pressure balance of the pressure of fluid infusion groove 3 interior solution and outside, solution is supplementary to be stopped.
After the interior solution of fluid infusion groove 3 is finished, outlet valve 7 cuts out, and inlet valve 6, pump 8 are opened simultaneously, and the testing liquid in hopper 2 joins fluid infusion groove 3 by pump 8, and in adding the process of solution, the air in fluid infusion groove 3 enters atmosphere by the end opening of sealed tube 5.When fluid infusion groove 3 is filled it up with, pump 8 quits work, and inlet valve 6 cuts out, and outlet valve 7 reopens, and system returns to the fluid infusion state.Outlet valve 7, inlet valve 6 can adopt solenoid valve, together with pump 8, with existing control system, are connected, and by detecting fluid infusion groove 3 interior solution levels, realize unlatching, closure automatically.
