Abstract
In a slurp pump abrasion test, in order to determine abrasive resistance of a slurry pump in slurry with given concentration including grains with certain size is a core content of the test. In the test bench, negative feedback regulation is introduced under the help of a sensor; a motor drives a screw nut mechanism to quickly determine a position of a suction inlet. A newly designed circulation system keeps concentration of the slurry in a blending tank and stability of grain size in coordination of the sensor, ensures that the test condition of the slurry pump is close to an actual situation, shortens the test period and improves the test accuracy and reliability. In the test process, the test condition can be changed according to the requirement, and different slurry pump performance tests can be compatible so that the service life of the slurry pump test bench is prolonged. The slurry pump test bench is characterized in that the slurry flowing inside the test bench can be detected and automatically regulated, stable test condition and high reliability.
Description
Technical field
The present invention relates to a kind of slag stock pump test stand of adjustable suction slag slurry concentration, the occasion in particular for quick online adjustment suction particle size of needs and concentration belongs to the testing apparatus field.
Background technique
In slag stock pump wear test, confirm the abrasive resistance of slag stock pump in the slag slurry of the particle with certain size of set concentration, be the core content of test.This test stand must help down at sensor, introduces reverse feedback and regulates, and confirms the suction port position fast by the motoring screw-nut body.The newly-designed circulatory system must cooperate down at sensor, keeps slag slurry concentration in the mixing tank, and stablizing of particle size guarantees that slag stock pump test conditions is near actual conditions.Shortened the test period, improved the accuracy of test,, in process of the test, can change test conditions as required with reliability, can compatible different slag stock pump performance tests, the life-span of improving test stand.
Summary of the invention
In order to improve the accuracy of slag stock pump performance test; Designed the slag stock pump test stand of adjustable concentration and particle size, in the circulatory system, under the help of measuring system; Compatible most of slag stock pump performance test improves the accuracy of test and the life-span of whole test platform.
Technological scheme of the present invention is:
Slag stock pump test stand, it is mainly by mixing tank, the water pump fixed pedestal, test pump, pump entrance, wearable valve, flowmeter, exit of pump and associated pipe are formed.Its main innovation is: slag stock pump test stand is made up of major loop, circulation loop, measurement of concetration loop, feed screw nut entrance location regulating mechanism.The major loop pipeline sucks slag slurry, the import that gets into the test pump from the middle part of mixing tank.The test pump is got slag slurry, through rising pipe from mixing tank top return in the mixing tank.Three valves that the adjustment lift is arranged on the rising pipe, a pressure transducer and a ultrasonic flowmeter of measuring flow of measuring lift.The suction port of intake pipe is made up of one section sludge suction rubber pipe, is convenient to adjust the slag slurry concentration that the suction port height is adjusted suction.The water pump suction port can change the suction port position through motor driving screw-nut body curved spout.The reversing arrangement by solenoid actuated is installed in the pipeline outlet port, and on-line weighing slag slurry quality under the cooperation of ultrasonic water level gauge, is confirmed slag slurry concentration fast, reconciles the suction port position.In order to solve slag slurry settlement issues, adopt recycle pump, stir the inner slag slurry of mixing tank.The recycle pump pipeline is connected the mixing tank bottom, can the slag slurry that settle down be returned so again, thereby keep the dynamic stability in slag slurry flow field.If suck from the bottom, therefore then inevitable blocking pipeline, adopts backflushing type, from the top relatively water layer diversion of clarification, stirs the slag slurry.Also have an additional innovation to be: after water pump was out of service, the solid impurity in the slag slurry can precipitate and stop up the whole pipeline in bottom, hinders circulation loop to restart work.In order to address this problem, can in the recycle pump pipe-line system, draw a branch, wash the silt of part deposition earlier open through branch line; Form whirlpool in the mixing tank bottom; Close fork pipeline is again washed the silt of all the other depositions open with the major cycle pipeline, guarantees the circulation loop proper functioning.
The invention has the beneficial effects as follows, design a kind of novel slag stock pump test stand, satisfy the most test requirements document of slag stock pump, and offer reference for further improving slag stock pump test stand performance.

In Fig. 4, the position of electromagnet (1) control outlet, electronic scale (2) cooperates the ultrasonic water level appearance to measure the concentration of outlet slag slurry.Baffle plate (3) prevents the slag slurry lunch environment that splashes.After measuring completion, the flexible pipe of hanging up (4) is put into mixing tank (5), discharge the weighing sample, ready for measuring next time.
In Fig. 5, in order to prevent slag slurry deposition, before test, open recycle pump (1), throttle down (3) is opened breeches pipe (2) and is located valve (4), stirs the slag slurry, and after mixing tank inside was fully stirred, throttle down (3) was opened valve (2), the circulation loop proper functioning.After the off-test, open flushing valve (5).
Claims (4)
1. the slag stock pump test stand of an adjustable suction slag slurry concentration, it is mainly by major loop, circulation loop, the measurement of concetration loop, feed screw nut entrance location regulating mechanism is formed.The water pump suction port changes the position through motor driving screw-nut body curved spout.
2. pump entry connects the mixing tube bottom, adopts backflushing type to stir the slag slurry, keeps the transient equiliblium of slag slurry in the mixing tube.
3. bifurcated pipeline of design in the circulation loop is washed too much deposition open, guarantees the circulation loop proper functioning.
