Description

A kind of portable liquid pressure tester
(1) technical field under
The utility model relates to a kind of tester of hydraulic engineering equipment, the particularly a kind of portable liquid pressure tester that can realize measuring in real time each technical indicator of hydraulic system.
(2) background technology
In recent years, continuous development along with capital constructions such as national highway sciences of bridge building, various engineering machinery are widely used in the engineering construction more, and hydraulic system is the indispensable important component parts of these equipment, but get rid of main dependence experience or undertaken for the fault of hydraulic system, do not have a kind of measurement testing apparatus easy to carry that can carry out comprehensive evaluation to hydraulic system by large-scale checkout equipment.At present domestic reaching in the world got rid of large-scale testing equipments such as main use hydraulic system multi-function test stand for the performance evaluation or the fault of hydraulic system, this makes troubles for the maintenance of main equipment, not only the expense of increase equipment transportation has also been wasted the time, has influenced the economic benefit of engineering machinery.
(3) summary of the invention
The utility model provides a kind of portable hydraulic system testing device in order to overcome the deficiency of above technology, can be done in real time the measurement of hydraulic system technical data, and it is low to have a cost, and volume is small and exquisite, is easy to carry, can adopt powered battery, be convenient to field work.
The technical solution of the utility model is achieved in that
The utility model relates to a kind of portable liquid pressure tester, comprises flow sensor, Flow Measurement Display Meter, temperature sensor, temperature indicator, and tensimeter, power supply, and corresponding inlet and outlet, above-mentioned parts are fixedly installed in the portable casing.Import, temperature sensor, flow sensor, outlet are in series, and import is connected with high pressure gauge, and temperature sensor is connected with temperature indicator, and flow sensor is connected with Flow Measurement Display Meter.
Portable liquid pressure tester of the present utility model is in series with integrated charge valve group between import and the temperature sensor, integrated charge valve group is made up of surplus valve that is in parallel and retaining valve.
Portable liquid pressure tester of the present utility model also is connected with the low-pressure meter that is used for subtest low pressure assembly in the portable casing, low-pressure meter is connected with test splice.
Portable liquid pressure tester of the present utility model, in order to be fit to open-air the use, described power supply is a battery.
Portable liquid pressure tester of the present utility model, by pipeline and test solution pressing system or unit Series, the numerical value of the flow when on-line measurement hydraulic system or parts work, pressure, temperature etc.
This tester can provide operating load for hydraulic system by integrated charge valve group, for the combination property of evaluation system provides foundation.
The beneficial effects of the utility model are that described device has been accomplished under the prerequisite that guarantees the complete stable performance of measurement function: volume is little, in light weight, powered battery, and especially the maintenance for camp equipment provides good surveying instrument.
