Abstract
The invention provides a digital display micro-pressure and micro-flow comprehensive detection bed and relates to a comprehensive detection system for the accurate detection on the micro positive pressure, micro negative pressure and flow of gas. The invention integrates micro positive pressure detection, micro negative pressure detection and flow classification detection into the detection system, adopts a uniform voltage regulator and an energy-saving micro pump which can simultaneously produce positive pressure and negative pressure in the same body. In addition, the invention solves the problem of low efficiency and energy and time consumption when detecting micro positive pressure, micro negative pressure and flow. Meanwhile, the detection bed is provided with a display system used by a digital display flow display, a flow sensor and a float flow meter and is also provided with a self-calibrating system for ensuring flow detection accuracy. The invention is mainly used for detecting the micro positive pressure, micro negative pressure and flow of vehicle fuel tank locks, micro valves as well as the intake and exhaust systems of a fuel tank and is also suitable for research units and detection departments which detect micro pressure and micro flow as well as other industries.
Description
Affiliated technical field
The comprehensive detection system that the present invention relates to the pressure-fired to gas, little negative pressure and micrometeor is accurately detected.
Background technology:
At present at needs to pressure-fired, little negative pressure; Can only go separately respectively to detect when under little positive condition of negative pressure, detecting flow; Efficient was very low when expense consuming time can detect the volume production product; Accuracy is lower, can't be accurate to testing result from imitating, and all do not have both at home and abroad and have this type of to have the checkout equipment of combination property.
Summary of the invention:
The present invention concentrates on the original classification detection system of pressure-fired and little negative pressure and flow in this detection system; In positive negative pressure system, all adopted buffer tank to guarantee the stability in the detection of positive/negative pressure source; And adopted the energy-saving minitype pump that can produce positive negative pressure consubstantiality simultaneously, solved the very low problem of expense energy efficiency consuming time when pressure-fired and little negative pressure and flow detected.The accuracy that is provided with digital display type appearance, flow sensor and suspended body flowmeter simultaneously and comes dependable flow to detect with system.
The present invention also utilizes U-tube manometer to form the self-calibration system of little intuitively positive negative pressure and flow, has guaranteed that detection system often can be accurate.
The present invention also is respectively equipped with the relay indicating light of power supply, micropump, display instrument.
Combined test stand source of the gas power of the present invention has adopted positive negative pressure consubstantiality micropump, and power consumes energy far below the conventional sense mode less than 3W.
The air-channel system of combined test stand of the present invention also is provided with the glueballs pump drainage gas system that manually produces positive negative pressure when not having electricity.
The whole gas circuit valves of combined test stand of the present invention have all adopted little shape needle valve, connect pipeline and all adopt silicon rubber hose.
Combined test stand of the present invention has also adopted pressure-fired and little vacuum table that can return to zero in pressure-fired and little detection of negative pressure system, guaranteed the accuracy that detects.
Comprehensive detection bench control system of the present invention also is respectively equipped with the working station indicator of power supply, little shape pump and digital indicator.
