Technical field

The utility model belongs to the anti-seawater corrosion field, particularly a kind of seawater that is used for environmental test simulation test device that splashes.

Background technology

The seawater simulation test device (chamber) that splashes is a kind ofly can reflect the corrosion condition of material at the seawater splash zone truly, and the environment test device that the corrosive nature of material under this environment is estimated and screened.Usually, the seawater simulation test case that splashes adopts the mode of rotor, splashes by adjusting the seawater that rotor that rotating speed of motor driven with control forms in various degree, thereby realizes simulation to seawater splash zone wave size.But rotor produces to splash its intrinsic shortcoming is arranged: the size of rotor rotating speed and the rotor determining positions in solution drop be splashed to the size of the power of specimen surface, and to the seawater of the such design simulation test case that splashes, drop splashes and impacts the power that specimen surface produces and can't regulate, thereby test findings is caused very big influence.And present seawater splashes, and the control of dissolved oxygen amount is simply by air pump air to be injected solution to realize in the simulation test case solution, and this can't regulate and control the variation of dissolved oxygen amount height in the solution.In addition, the simulation test case has temperature control equipment though existing seawater splashes, and does not have the function of relative humidity control, and can not gather and record temperature, relative humidity, therefore, be difficult to the ANOMALOUS VARIATIONS that occurs in the complete process of the test is studied.

Along with the improvement of seawater splash zone corrosion test standard and the needs of further investigation, people often need to change seawater the splash impulsive force of splash droplet and the size of oxygen level in the simulation test, and also more and more higher to the splash requirement of the reliability of simulation test device and control accuracy of seawater.Therefore need the novel seawater of the design simulation test device that splashes to satisfy above-mentioned requirement.

The utility model content

The purpose of this utility model be to provide one can change droplet impact power size and dissolved oxygen content just, can be to seawater seawater that simulation test the temperature inside the box and relative humidity reliably controls and gather in real time and the write down simulation test device that splashes that splashes.

A kind of seawater that is used for environmental test simulation test device that splashes, it is characterized in that test unit structurally is made up of chamber, liquor box and control box three parts, comprise spray head, shower, recirculatory pipe, anti-corrosion solution pump, the time relay, sample, specimen mounting, pressure transducer, Temperature Humidity Sensor, condenser, well heater, liquid level sensor, oxygen or nitrogen cylinder, control box, industrial computer, chamber, liquor box.

Specimen holder, spray head, shower and pressure transducer, Temperature Humidity Sensor, well heater, condenser are set in the chamber; Sample is statically placed on the specimen holder of bottom in the chamber, uniform spray head in the chamber, and shower connects recirculatory pipe, anti-corrosion solution pump and the time relay, and pressure transducer is in the test stand bottom; Industrial computer in the control box is connected with well heater with condenser by control circuit; Liquid level sensor is set in the liquor box and is connected, the solution of saturated nitrogen or saturated oxygen is provided with nitrogen or welding bottle.

Sample is statically placed on the packaged type specimen holder of the interior bottom of chamber, by controlled swing spray head uniform on it, realize that specimen surface is subjected to the impact of the drop under certain hour, the certain pressure, the size of the power of the droplet impact that the testing requirements specimen surface is subjected to and attack time be by the comprehensive adjustment of the recirculatory pipe, anti-corrosion solution pump and the time relay that are connected with shower, and with the monitoring of the pressure transducer of the test stand bottom incompatible realization that matches; The control of humiture can be according to the setting of operation circuit in the chamber, and by the monitoring of Temperature Humidity Sensor, applicable industry control microcomputer is realized cooling, fallen wet and intensification by control circuit switch condenser or radiator valve.Feed nitrogen or oxygen in the liquor box, the solution of saturated nitrogen or saturated oxygen is provided, and realize the droplet impact specimen surface by the anti-corrosion solution pump.

The solution spraying of certain dissolved oxygen amount that the shower nozzle of the utility model by can rule swing will require is to the sample that leaves standstill, by the adjusting of anti-corrosion solution pump, recirculatory pipe and the control of the time relay, the size of impulsive force of random adjustment drop and the time of impact have been realized; Adopt condenser and well heater with control seawater splash temperature and relative humidity in the simulation test case, thereby improve the stability and the reliability of chamber; In addition, adopt industrial computer by real-time temperature/humidity data collection and record with the monitoring of realization to entire test in the chamber.
