The air compressor is communicated with the spray gun through the gas conveying pipe. The gas conveying pipe is provided with the pressure gauge and the pressure control valve. The lower end of the spray gun is provided with the spray nozzle. The sample workpiece rotary table is positioned below the spray nozzle. The sample workpiece rotary table is driven to rotate by the variable frequency motor. The sand storage chamber is communicated with the spray gun through the sand conveying pipe. The spray gun and the sample workpiece rotary table are positioned in the sealed machine body. The sand storage chamber is positioned at the lower part inside the machine body. The air compressor, the pressure gauge, the pressure control valve, the control box, the dust remover and the variable frequency motor are positioned outside the machine body. The dust remover is used for removing dust inside the machine body. The spray gun has a spray angle of 10 degrees to 90 degrees. Due to the adoption of the jet-type gas-solid erosion testing device, a sample workpiece is simultaneously eroded by both gas and solid phase flows. In the working process of the jet-type gas-solid erosion testing device, a flow field is stable and the impact angle can be accurately controlled.

In use there are shortcomings such as the flow field is stable inadequately, angle of attack can not accurately be controlled in the said equipment.
Summary of the invention
Gu the purpose of this invention is to provide a kind of jetting type gas/erosion proving installation, Gu this jetting type gas/erosion proving installation is on industrial sand-blasting machine basis, in conjunction with ASTM-G76-83 standard and testing requirements, to the upgrading that existing erosion proving installation carries out, the present invention has overcome the shortcoming that the flow field is stable inadequately, angle of attack can not accurately be controlled that in use exists.The present invention is simple in structure, operates simple and easyly, and the exemplar sheet erosion wear testing that can be used for simulating lifting airscrew erosion operating mode provides the research technique support for selecting high-abrasive material and research erosive wear mechanism.
The present invention mainly is made up of three parts, the one, compressed-air supply system: the effect of this part is the dry gas that certain pressure is provided for this pilot system, by regulating the tensimeter on pressure control valve and the sand-blasting machine, effectively pilot-gas go out atmospheric pressure, and then change gas velocity and sandblast speed.The 2nd, the working cell: in work chamber, abrasive material at first mixes with high velocity air, Gu produce gas/two-phase mixed airflow, abrasive material sprays from nozzle with air-flow subsequently, strikes the exemplar surface and produces erosive wear.The 3rd, dust collecting system: main effect is health and the environmental protection that is used to guarantee operating personnel, absorbs dust.In addition, the arbitrarily angled realization of angle of gun of the present invention in 10 °～90 ° is to the exemplar sandblast, and testing table has the function of frequency control simultaneously.
The present invention specifically is by air compressor machine, tensimeter, pressure control valve, control box, fly-ash separator, spray gun, nozzle, the exemplar turntable, sand storage chamber, variable-frequency motor, air shooter, sand delivery pipe and organization, air compressor machine is communicated with spray gun by air shooter, air shooter is provided with tensimeter and pressure control valve, the spray gun lower end has nozzle, the exemplar turntable is positioned at the nozzle below, the exemplar turntable is driven by variable-frequency motor and rotates, sand storage chamber is communicated with spray gun by the sand delivery pipe, spray gun and exemplar turntable are positioned at the body of sealing, sand storage chamber is positioned at the below of internal body, air compressor machine, tensimeter, pressure control valve, control box, fly-ash separator and variable-frequency motor are positioned at engine body exterior, and fly-ash separator is used for the dedusting of internal body.
Described lance ejection angle is 10 °～90 °.
Principle of work of the present invention is: pressurized air flow at high speed in spray gun of utilizing air compressor machine to produce forms negative pressure, produce ejector action, the abrasive material of sand storage chamber below the unit room is sucked in the spray gun by sand spit, then with pressurized air, by nozzle, with different angles, speed, the exemplar surface of difference directive speed change rotation, by abrasive particle high speed impact effect within a certain period of time, come the erosive wear resistance of test material.The sample chamber is totally-enclosed, consider to be furnished with the fly-ash separator that constitutes by blower fan and sack cleaner based on environmental protection and operator ' s health aspect, be furnished with the sand storage chamber that abrasive material reclaims in the bottom, sample chamber, abrasive material after the ejection falls in the sand storage chamber, and dust then is inhaled in the interior dust suction cloth bag of fly-ash separator.
The invention has the beneficial effects as follows: the present invention makes exemplar be subjected to the erosion of gas/fixed double phase flow simultaneously; The present invention can be used for the selection and the research of erosive wear mechanism of high-abrasive material.The present invention flow field in the course of the work is stable, and angle of attack can accurately be controlled.
