The bottom of a high level water tank is connected with a low level water tank through a connecting pipe, after the cavitation adjustment device, the fluid is respectively connected with a pump A4 and a valve A6 through a tee, and the serial bypass is respectively connected with the outlets of the valve A6 and the pump A4 after addedly arranged with a valve 7, the pipeline passing through a pump A5, a valve A8, a flowmeter A9 and another pipeline are joined through the tee and are back flown into a high level water tank 1 through a valve A12.The utility model has the advantages of truly realize the multi-functions integrated: in a system, the performance test, serial test, parallel test, cavitation test, variable speed adjustment test, and automatic water supply control test, etc. can be realized simultaneously; the system adopts the ''open'' type design, and it can be also reassembled or the function can be expansed when necessary.
Description
Technical field
The utility model belongs to the device in the fluid machinery teaching research.
Background technology
Pumps ﹠ Fans is important fluid machinery, and it is the power-equipment that mechanical energy is converted into fluid potential energy and kinetic energy, is widely used in national economy all departments.For this reason, specialties such as chemical industry, heat energy, plumbing have all been offered this subject, and fundamental purpose is to make the student grasp rudimentary knowledge and pump performance and method of testing that basic theories, primary structure and the parts of pump, relevant type selecting and operation are regulated.Achieve the above object, theory teaching and practical teaching are two important steps.
And at present, the test unit of domestic relevant pump can not satisfy the needs of this respect far away, is mainly reflected in: 1, insufficiency: generally can only finish performance test, tandem test, test in parallel; 2,, therefore, produce the test that a large amount of corrosion products has a strong impact on pump owing to corroding in the system after operation a period of time, and then equipment manufacturing cost is too high if adopt stainless steel material because device adopts metal material; 3, existing system is the design of " sealing " formula, can't carry out secondary development to device, greatly reduces the value of device.
Summary of the invention
The utility model provides a kind of centrifugal pump multifunction test device, the problems referred to above that exist with the test unit that solves present domestic pump.The technical scheme that the utility model is taked is: the left-sided system of device is: connected with position, end water tank a2 through connecting pipe by elevated tank 1 bottom, cavitation regulating device a3 is arranged in this low flush tank a2, link to each other with valve a6 with pump a4 respectively by threeway, inline bypass is after installing valve a7 additional, be connected in the endpiece of valve a6 and pump a4 respectively, after above-mentioned connection, pipeline is respectively through pump a5, valve a8, flowmeter a9 and another road, be valve a11, flowmeter a10, converge and be connected with elevated tank 1 through valve a12 through threeway; The right-sided system of device: connect with position, end water tank b2 through connecting pipe by elevated tank 1 bottom, cavitation regulating device b3 is arranged in this low flush tank b2, link to each other with valve b6 with pump b4 respectively by threeway, inline bypass is after installing valve b7 additional, be connected in the endpiece of valve b6 and pump b4 respectively, after above-mentioned connection, pipeline is respectively through pump b5, valve b8, flowmeter b9, reverse checkvalve b21 and another road, and promptly valve b11, flowmeter b10, reverse checkvalve b22 converge and are connected with elevated tank 1 through valve 12, teletransmission tensimeter 23 and valve 24 through threeway; Vacuum meter 13 and 17 is connected to the two ends of pump a4, and vacuum meter 14 and 18 is connected to the two ends of pump a5, and vacuum meter 16 and 20 is connected to the two ends of pump b4, and vacuum meter 15 and 19 is connected to the two ends of pump b5.
The flow process of fluid of the present utility model: with the left side is example, because of symmetrical right side as the same.
By water filling in elevated tank and open each valve and reach setting until water level, stop to add water then, during operation, water enters status water tank a2 by elevated tank 1 through the connecting pipe gravity flow, through cavitation regulating device a3 and pump a4, pump a5 connects, wherein again, valve a6 only opens when doing experiment in parallel, and other situation is closed condition.
When the performance test of single pump, shut-off valve a6, a7, a8, open valve a11, a12, fluid will flow back to elevated tank along pump a4, valve a11, flowmeter a10 and through valve a12, finish the performance test to pump a4; On the contrary, shut-off valve a7, a11, open valve a6, a8, a12, fluid will flow back to elevated tank along pump a5, valve a8, flowmeter a9 and through valve a12, finish the performance test to pump a5.
When the series connection experiment, valve-off a6, a11 open valve a7, a8, a12, and fluid will flow back to elevated tank through pump a5, valve a8, flowmeter a9, valve a12 along pump a4 outlet, valve a7.
When parallel connection is tested, shut-off valve a7, open valve a6, a11, a8, a12, fluid will be divided into two-way pass through respectively valve a6, pump a5, valve a8, flowmeter a9 then with another road fluid promptly: the fluid through pump a4, valve a11, flowmeter a10 converges mutually, and flows back to elevated tank through valve a12;
Cavitation experiment and speed change are regulated experiment, and the flow process of fluid is identical with the performance test of single pump.The variable frequency control experiment is then identical with the parallel connection experiment.
Advantage of the present utility model is: 1, really realized one-machine-multi-function: in a cover system, can finish performance test, tandem test, test in parallel, cavitation experiment, speed change adjusting test, self water feeding control test etc. simultaneously; 2, system adopts the design of open to the outside world type, can re-assembly where necessary or the function expansion; 3, adopt full anti-corrosion material design, thoroughly solved and adopted anti-corrosion material and finish contradiction between the cavitation experiment; 4, make full use of various test instrumentations, make in a covering device and can independently finish two groups of experiments simultaneously, that is: a covering device is equivalent to two covering devices, thereby has improved its cost performance.
