The invention relates to a calibration device and a calibration method for an oil and gas recovery detector. The calibration device comprises an outer casing, an air inlet, a main control module, a pressure generating device, at least one pressure sensor, a flow meter module, a fan, a first electromagnetic valve, a second electromagnetic valve and a communication interface; according to a preset pressure, the main control module connects at least a part of the pressure sensors whose pressure ranges are not less than the preset pressure in the pressure sensors to the air inlet; the main controlmodule controls the pressure generating device to pressurize or depressurize according to the preset pressure and a preset pressure error so that a comparison value between the pressure detected by the pressure sensors and the preset pressure is within a preset error range; and the main control module receives the gas flow output by the flow meter module and controls a comparison value between the fan rotation speed flow and a preset flow within a preset flow error according to the preset flow and the preset flow error. The calibration device and the calibration method are used for reducing the calibration tasks, can improve the calibration efficiency, can avoid human intervention, and can improve the calibration accuracy.
Description
technical field [0001] The invention belongs to the technical field of environmental detection instruments, and in particular relates to a calibration device and a calibration method for an oil gas recovery detector. Background technique [0002] The oil gas recovery detector used in gas stations or tank trucks has certain strict requirements on pressure and flow, so it is necessary to perform pressure calibration and flow calibration on the oil gas recovery detector. At present, the oil gas recovery detector provides pressure and flow calibration The equipment is usually an independent pressure calibrator and an independent flow calibrator. The pressure calibration provided in the pressure calibrator is pressurized and decompressed by manual cranking, which needs to be manually adjusted to the target pressure required for calibration. In addition, the flow calibrator only has the function of flow measurement and has no power source for pumping air, so it needs to be equippe...
