Abstract
The utility model discloses a hydraulic oil pump test bed hydraulic system, which comprises an oil storage box, a test bed, a filter device and a cooler which are connected through pipelines, wherein an electric heating device is arranged on the oil storage box, and a circulating pump which is used for self circulation of hydraulic oil is arranged between the oil storage box and the filter device. The hydraulic oil pump test bed hydraulic system effectively improves test efficiency of a hydraulic oil pump, increases cleanliness of system test oil liquid, effectively balances system oil temperature, can prevent rehandling, reduces cost, and can be used for mass production, and is not high in demands of equipment and investments.
Description
Technical field
The utility model relates to a kind of hydraulic-pressure pump test stand hydraulic system.
Background technique
The hydraulic-pressure pump manufacturer that is used on automobile and the engineering machinery on the Domestic market at present adopts the oil outlet high-pressure filteration mostly, an oil circuit, a fuel tank independently; Must quit work when oil circuit has dirt filter screen is removed cleaning, and the dirt of high pressure filter to receive dirt amount little, must often dismantle; Like this; The oil hydraulic pump that test is come out still maybe be because the untimely inside of filter rinsed be unclean, and the requirement that does not reach turbidity test also needs flushing separately; When so not only taking a lot of work but also costly power material resources, very calculate.Simultaneously since when test because oil cleanliness is not high, residual in the hydraulic-pressure pump have a metallic dust, this can aggravate the oil hydraulic pump inter deterioration again, has reduced the working life of hydraulic-pressure pump.
Summary of the invention
The utility model is to the deficiency of existing technology; Designed and developed out and a kind ofly can effectively improve the hydraulic-pressure pump test efficiency; Improve the turbidity test of system test fluid; The hydraulic-pressure pump test stand hydraulic system of balanced system oil temperature, this test stand hydraulic system can avoid the duplication of labour to reduce cost, and can be used for mass-produced and to equipment and drop into less demanding.
The hydraulic-pressure pump test stand hydraulic system of the utility model; Comprise the fuel reserve tank, test stand, filtrating equipment and the cooler that are connected through pipeline; Said fuel reserve tank is provided with electric heater, it is characterized in that: between said fuel reserve tank and the filtrating equipment through pipeline be connected one be used for the hydraulic oil self-loopa recycle pump.
Said filtrating equipment is the oil purifier of two-way parallel connection, is the two-way oil strain station that the two-way oil purifier forms through parallel way.
A kind of filter type of hydraulic-pressure pump experimental bench system fluid is stipulated in the test method; " the solid pollution grade of test oil must not be higher than 19/16 for pass the test article (code name C) ", satisfy this index we design a two-way oil strain station and guarantee in experimental bench system.Make fluid also reach abundant filtration.The measure of filtering fluid is recycle pump to be installed start recycle pump during whole test or when needing in system.Fluid by fuel reserve tank through fuel supply line → recycle pump → return tube → two-way oil strain station → cooler → get back to fuel reserve tank.Heater cartridge is in fuel reserve tank.The formation closed loop cycle is reciprocal.Fluid is through continuous the filtering repeatedly in two-way oil strain station.The oil outlet design of fuel tank makes the fuel tank internal memory not live any impurity and dirt at the lowest part of fuel tank.Dirt all is intercepted in the circulating filtration process in the oil purifier in the two-way oil strain station in the system.So not only can satisfy pressure testing has required also to solve the cleaning fuel reserve tank with the turbidity test of oil trouble and the worried oil pump tested that also cleaned simultaneously.His another effect is exactly to make whole system oil temperature balanced, and it is too high can not produce the oil temperature in the part.
Adopting the two-way oil strain in addition is to stop up more renew cartridge for fear of the single channel oil strain and stop experiment work, and delays the situation of production.The two-way oil purifier can switch to a road subsequent use oil strain and use after No. one oil purifier stops up generation.Can realize the work of not shutting down like this.Two-way oil strain station will be designed and adopt 630 liters of oil purifiers of peak rate of flow to receive the dirt amount greatly, can prolong the more renew cartridge cycle, reduces and changes number of times.Fuel filter element is used in 40 microns, and 30 microns, 20 microns, 10 microns level Four, the filtration repeatedly that improves filter precision step by step.The pressure testing luboil cleanness not only can surpass the C class precision of stipulating in the experimental technique like this, and can reach the requirement of B class precision.Most critical be that the pressure testing of high cleanliness can be cleaned in test the residue of oil pump in production process that oil pump is with oil and all tackled in filter.Thereby the product that obtains the inner chamber cleaning reaches more reliably oil pump turbidity test when dispatching from the factory and guarantees.
The utility model has effectively improved the hydraulic-pressure pump test efficiency; The turbidity test of system test fluid have been improved; Efficient balance system oil temperature, this test stand hydraulic system can avoid the duplication of labour to reduce cost simultaneously, and can be used for a large amount of produce and to equipment and drop into less demanding.
Description of drawings
Accompanying drawing 1 is the total arrangement schematic representation of hydraulic-pressure pump delivery test platform and hydraulic system.
Among the figure: 1, test stand; 2, noise barrier; 3, recycle pump; 4, fuel reserve tank; 5, electric heater; 6, cooler; 7, oil purifier.
Embodiment
Shown in accompanying drawing; The hydraulic-pressure pump test stand hydraulic system of the utility model; Comprise the fuel reserve tank 4, test stand 1, filtrating equipment and the cooler 6 that are connected through pipeline; Fuel reserve tank 4 is provided with electric heater 5, between fuel reserve tank 4 and the filtrating equipment through pipeline be connected one be used for the hydraulic oil self-loopa recycle pump 3, filtrating equipment is the two-way oil strain station that forms through parallel way for the two-way oil purifier.Regulation " the solid pollution grade of test oil must not be higher than 19/16 for pass the test article (code name C) " in the ordinary test standard method, satisfy this index we design a two-way oil strain station and guarantee in experimental bench system.Make fluid also reach abundant filtration.The measure of filtering fluid is recycle pump to be installed start recycle pump during whole test or when needing in system.Fluid by fuel reserve tank through fuel supply line → recycle pump → return tube → two-way oil strain station → cooler → get back to fuel reserve tank.Heater cartridge is in fuel reserve tank.The formation closed loop cycle is reciprocal.Fluid is through continuous the filtering repeatedly in two-way oil strain station.The oil outlet design of fuel tank makes the fuel tank internal memory not live any impurity and dirt at the lowest part of fuel tank.Dirt all is intercepted in the circulating filtration process in the oil purifier in the two-way oil strain station in the system.So not only can satisfy pressure testing and also clean oil pump tested with trouble and worried while that oily turbidity test have required also to have solved the cleaning fuel reserve tank, another effect is exactly to make the warm equilibrium of whole system oil, and it is too high can not produce oily temperature in the part.
