The measurement of coal calorific value, methanol calorific value, gasoline calorific value, heavy oil calorific value, and diesel calorific value will be selected when Hebi Yinghua Instrument Co., Ltd. If the analysis result is low, the valve on the filter switch can be closed to observe whether the float of the “pumping” flowmeter is slowly descending. If it can be lowered to below 1L/min, the airtightness is good, otherwise the airway may leak or block. Part. When the pneumatic system fails, the following steps can be checked. 1. First check whether the silicone rubber tube from the exhaust pipe joint of the quartz tube in the high temperature furnace to the air switch is damaged and replaced in time (generally, it is easy to break at the suction pipe joint); 2. Check if the Vaseline of the filter switch starts To the sealing effect, add Vaseline evenly, and check if the absorbent cotton in the filter switch is suitable as long as it can filter the gas path. It is not good or it can block the gas path; 3. Check the inlet and outlet silicone rubber tubes of the electrolysis cup. Whether the joint is leaking, re-install after the removal to confirm; 4, check whether the sealing ring of the upper and lower joints of the drying pipe is intact, and add Vaseline to prevent air leakage, and check whether the lower joint has silica gel falling in order to prevent blockage of the gas path; Adjusting the one-way throttle valve in the gas path makes the pumping capacity be about 2.0L/min, the blowing flow rate is 1200±200mL/min, and the one-way throttle valve is locked to prevent the micro vacuum pump from vibrating to change the flow rate. 6. Check if the micro vacuum pump (exhaust pump) is faulty or leaking. If it is, replace it with a new one (recommended to use original accessories). Original link: http://
