Description
Technical field
The present invention relates to erosive wear measuring technology, particularly a kind of experiment dress for simulating marine propeller erosive wear
It puts.
Background technology
Soil erosion aggravates caused by being reduced due to vegetation coverage, and many river load contents in China are larger.Silt
Main component is quartzy (SiO2), and quartz particles are the erosion of silt flow and gas with its wedge angle or half wedge angle abrasion hydraulic set
The main reason for erosion creates condition, this is hydraulic set abrasion.Hydraulic set median year is in the part of appliance of underwater operation,
The repeated stock and cutting of the blade and gear drive of such as propeller silt in by river, eventually due to serious wear
It scraps.It is reported that the Yellow River pumping plant flow passage components are scrapped in operation after 2000~4000 hours, and the high pump of lift is only run
It just scraps within 1000 hours.The economic loss that China thereby results in every year is up to several hundred million yuans.
For this reason, it may be necessary to the anti-silt Erosive Properties to water conservancy equipment are studied, wherein to by silt erosive wear
More serious marine propeller, which carries out erosive resistance, which to be researched and analysed, more seems necessary.
Invention content
The purpose of the present invention needs to provide a kind of experimental provision for simulating marine propeller erosive wear aiming at above-mentioned.
The experimental provision of simulation marine propeller erosive wear provided by the invention, by rack, the sand positioned at frame lower
When starching case, the propeller being placed in mortar case, rack-mounted propeller driving mechanism and being rotated for measuring propeller
The weight beam composition of the propulsive force of generation.
The propeller driving mechanism includes frequency control motor, and frequency control motor passes through the tooth that is mounted in gear-box
Wheel drive mechanism drives the propeller, and gear-box is fixedly connected with the platform that the sliding rail that can be set along upper rack slides, becomes
Frequency modulation speed motor is mounted on platform；
One end of the weight beam is fixed in rack, and the other end connects with the gear-box.
When testing the erosive resistance of propeller with experimental provision of the present invention, first by the sediment concentration of setting in sand
Deployed mortar in case is starched, then starts frequency control motor, frequency control motor drives propeller by gear drive
By the rotating speed rotation of setting in mortar in mortar case, the propulsive force that propeller rotation generates is transmitted to platform by gear-box,
Make platform forward slip on sliding rail, weight beam is stretched by gear-box, when the pulling force of weight beam and pushing away for propeller
During into dynamic balance, platform stops forward slip on sliding rail, and propeller stops moving ahead, only rotate on the spot, the reading of dynamometer at this time
Number is the propulsive force that propeller rotation generates；After propeller is rotated up to the examination time of setting, frequency control motor is shut down,
Propeller stops rotating, under the pulling force effect of weight beam, propeller, gear-box and platform reset；Then by propeller
Remove, by detection, measure the erosive wear amount of propeller, so as to obtain propeller erosive wear amount and mortar sediment concentration,
Relationship between revolution speed of propeller, propeller rotational time and propeller propulsive force, as researching and analysing the anti-mud of tested propeller
The foundation of husky Erosive Properties.
Structure of the present invention is brief, low cost, can simulate steamer in the river containing silt when driving propeller by silt
The process of erosive wear can measure the erosive resistance of propeller by simulated experiment, and the design studies for propeller carry
For foundation.

Into.
Wherein rack 6 is square framework type structure, and the mortar case 9 equipped with mortar is placed on the lower part of rack.The spiral
Paddle driving mechanism is：The platform 8 that installation can be slided along sliding rail on two 3. sliding rails of sliding rail is fixedly mounted on the top of rack, flat
Frequency control motor 7 is installed on platform, frequency control motor by being mounted in gear-box 1, by being arranged above and below and intermeshing
The gear drive 2 that four gears are formed drives propeller 5 to rotate, and gear-box is fixedly connected with platform, and 5 front end of propeller is stretched
Go out gear-box, be laterally disposed in mortar case, the tank wall of front end and mortar case keeps a determining deviation (to ensure that propeller rotation moves ahead
To the tank wall for not touching mortar case during the tension balanced of its propulsive force and weight beam), propeller rear end passes through with gear-box
Bearing 4 connects.One end of the weight beam 10 is fixed in rack, and the other end is connect with gear-box, works as weight beam
The rotation of pulling force and propeller generate propulsion dynamic balance when, propeller stops moving ahead, and rotates on the spot, at this time the reading of dynamometer
The propulsive force that as propeller rotation generates.
