Background technology
When flow media is liquid-solid mixture in fluid device, due to depositing for the solid particle that is entrained in liquid flow
, there can be very serious wear erosion to flow passage components, such as in pipeline, pump, the hydraulic turbine, heat exchanger etc., this can cause to set
Standby degraded performance, reliability reduction and operation lifetime reduction, the use to equipment produce serious influence.Therefore, solid-liquid two-phase
The measure of abrasion and quantization are very important in industrial equipment is designed and is safeguarded.
At present, wear test is carried out generally by the following manner.This mode is usually directly to use fluid machines
Tested, by prolonged operating, the sample that last wear test is obtained is analyzed.But, in this way
Have the following disadvantages：1. test period is long, compares and loses time；2. abrasion condition is observed after experiment every time, is relatively difficult to reality
It is existing, abrading section stripping and slicing can only be handled, then be placed under ESEM and observe.What so each experiment will more renew sets
It is standby, waste of resource；3. the independent variable factor that can be typically tested is excessively single.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of that above-mentioned background technology can be used for test solid-liquid two-phase to wear and tear there is provided a kind of
Experimental rig, the device should be able to carry out under numerous conditions sample plate abrasion condition measurement, and with test period it is short,
The characteristics of testing efficiency is high.
The technical scheme that the present invention is provided is：
A kind of experimental rig for being used to measure the abrasion of solid-liquid two-phase, it is characterised in that the device includes：For collection belt
Grain liquid liquid collection tank, can be rotatably arranged at around vertical axis in liquid collection tank and be provided with several specimen holders
Rotating circular disk, be arranged on above rotating circular disk for the nozzle disc to sample jet band particle-liquid, be spray by pipeline
Mouth disk is provided with particle-liquid and carried out by the second motor-driven pump and to the band particle-liquid that liquid collection tank is exported
The suspension tank of pump is conveyed to after processing again.
The axis vertical arrangement of the nozzle disc, the upper surface of nozzle disc connects described pipeline, spray by flange
The circumferencial direction of mouth disk is evenly equipped with some mouth sprays.
The rotating circular disk is fixed in a rotating shaft arranged vertically, and the first motor drives described turn by gearbox
Axle.
Described suspension tank is configured with agitator.

Being made on the rotating circular disk has some radial arrangements and the regulating tank for fixing specimen holder.
The present invention use principle be：Sample can be fixed on specimen holder and followed by rotating circular disk to set
Rotating speed rotates, and is sprayed with particle-liquid from the mouth spray of nozzle disc with the speed set up and sample is sprayed, unrestrained liquid
Body flows into suspension tank again from liquid collection tank, is then pumped out and transports to rotating circular disk by pipeline again；By setting time
After operating, you can the abrasion condition of measurement sample.
The beneficial effects of the invention are as follows：Rotating speed due to rotating circular disk, the flow velocity with particle-liquid can be adjusted as needed
Section is determined, it is thus possible to variable grain concentration, variable grain particle diameter, different in flow rate, the different angle of shocks, different impact distance,
The abrasion condition of sample plate under the conditions of different rotation rates etc. are a variety of；And due to being provided with several samples on rotating circular disk
Product frame, thus the wear testing of several samples can be carried out simultaneously, so as to save considerably the testing time, survey is greatly improved
Try efficiency.
