Description
Technical field
The utility model relates to a kind of test platform, relates in particular to a kind of high-pressure water pump Testing Platform.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, gaseous mixture and contain suspended solids.
In exploitation, development and the product testing process of all kinds of water pumps, need a large amount of Flow characteristics and drag characteristic laboratory data, these data are for improving product technology level, guaranteeing that quality of product is vital.Therefore the testing water pump platform that has a superior performance is extremely necessary.
Existing common water pump test platform is all the artificial closely size of manual control valve, by observing flow process, lift table carrys out independent record data, numerous and diverse and easily make mistakes.Particularly for high-pressure water pump, manual control valve reaches manual control valve and reaches more difficult while oneself wanting the fixation pressure of test and flow, and hydraulic pressure is very large, and safety is had to very large hidden danger.
Summary of the invention
The purpose of this utility model is defect and the deficiency that overcomes prior art, provides a kind of testing precision high, safe and reliable high-pressure water pump Testing Platform.
For realizing above object, technical solution of the present utility model is: a kind of high-pressure water pump Testing Platform, comprise water storage tank, inlet pipeline and rising pipe, it is characterized in that: on described rising pipe, be provided with high pressure steady-flow tank, the top of described high pressure steady-flow tank is provided with pressure transducer, the water outlet of described high pressure steady-flow tank connects electric control valve, on the rising pipe between electric control valve and water storage tank, be separately installed with temperature transducer and turbine flowmeter, described pressure transducer, electric control valve, the control end of temperature transducer and turbine flowmeter is connected with control centre respectively.
Described electric control valve is electric multi-stage axial flow labyrinth modulating valve.
Duct length between described electric control valve and turbine flowmeter is not less than 2 meters.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model, by rational pipe-line layout, has solved the problem of high-pressure water pump testing property difficulty, and whole system testing precision is high, reaction velocity is fast, general pump performance parameters all can be tested out, and rendering performance curve, use more convenient.
2, the utility model has been installed a high pressure steady-flow tank specially at the water outlet of high-pressure water pump, steady-flow tank can so that unsettled hydraulic pressure and the flow of water pump output here integrate, become a stable delivery pressure, and the working pressure of steady-flow tank is 35Mpa, can bear the high pressure in high-pressure water pump outlet port completely, use safer.
3, the utility model comes flow and the pressure of adjusting water outlet pipeline with electric multi-stage axial flow labyrinth modulating valve, this modulating valve can be controlled the flow velocity that flows through the medium in valve completely, significantly reduce the noise that pressurized gas or steam produce in valve, the liquid that stable multi-level step-down can effectively make can not produce cavitation erosion, is the control valve using in the stable performance of high-pressure medium place.
4, the distance between turbine flowmeter of the present utility model and electric control valve surpasses 2 meters, like this from high-velocity flow out steady-flow tank to arrive turbine flow timing flow velocity after a segment distance basicly stable, test data is more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: water storage tank 1, inlet pipeline 2, rising pipe 3, high pressure steady-flow tank 4, pressure transducer 5, electric control valve 6, temperature transducer 7, turbine flowmeter 8, control centre 9.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is described in further detail.
Referring to Fig. 1, a kind of high-pressure water pump Testing Platform, comprise water storage tank 1, inlet pipeline 2 and rising pipe 3, on described inlet pipeline 2, be provided with pipeline mounted pump, ball valve and flange assembly, flange assembly and high-pressure water pump suction flange match, on described rising pipe 3, be provided with high pressure steady-flow tank 4, the top of described high pressure steady-flow tank 4 is provided with pressure transducer 5 and bleeder port, the water intake of high pressure steady-flow tank 4 is wound around flexible pipe by high pressure and is connected with high-pressure water pump water outlet, in flexible pipe two assembling screw thread, tooth is so that connect tightr, the water outlet of described high pressure steady-flow tank 4 connects electric control valve 6, on the rising pipe 3 between electric control valve 6 and water storage tank 1, be separately installed with temperature transducer 7 and turbine flowmeter 8, duct length between described electric control valve 6 and turbine flowmeter 8 is not less than 2 meters, described pressure transducer 5, electric control valve 6, the control end of temperature transducer 7 and turbine flowmeter 8 is connected with control centre 9 respectively.
Electric control valve 6 in the utility model adopts the electric multi-stage axial flow labyrinth modulating valve that is more suitable for high-pressure medium field.
Working principle of the present utility model is: before test, the high-pressure water pump of needs test and the pipeline of test platform are connected.Start test platform and high-pressure water pump, water in water storage tank 1 is through the pipeline mounted pump on inlet pipeline 2, ball valve and flange assembly enter high-pressure water pump, water in high-pressure water pump enters from the water outlet of water pump the high pressure steady-flow tank 4 being arranged in rising pipe 3 after water pump pressurization, the pressure transducer 5 on high pressure steady-flow tank 4 tops can detect the hydraulic pressure in high pressure steady-flow tank 4 constantly, when the pressure in high pressure steady-flow tank 4 is about to exceed standard, can open bleeder port and lay down partial pressure, the tank internal pressure finally making is no more than 30Mpa, pressure transducer 5 passes to control centre 9 in real time by pressure data simultaneously, control centre 9 controls the opening degree of electric multi-stage axial flow labyrinth modulating valve according to the variation of pressure data, thereby reach the object of reconciling the pressure and the flow that pump mouth of a river pipeline, at current, pass through in the process of rising pipe 3, temperature transducer 7 and turbine flowmeter 8 can detect flow and the temperature rise of current, and data are sent to control centre 9, control centre 9 gathers all data and after detailed calculating, can generate on backstage a test curve figure, picture flow, lift, energy conversion efficiency, rotating speed, the pump performance that temperature rise etc. are general can comprise wherein, and in test process, also can obtain more full and accurate concrete data by controlling the rotating speed of high-pressure water pump.
