XCMG Chu Sheng Tanker has always been in the leading position in the industry. Due to more and more users, it is not very familiar with certain aspects of operation. Now our technicians talk about the use of flowmeters for tank cars.
( 1 ) .Flowmeter system precision instrument, the detection chamber in the measurement room is very small. Therefore, large particles and other impurities must not enter the flowmeter. It is forbidden to use the flowmeter without a filter.
(2) The flow meter may not exceed a predetermined flow rate and pressure range, during continuous operation, the flow conduit should generally not exceed (600 ~ 800) L / min , the maximum flow rate in order to meet a sudden increase in flow rate occurs while etc. Specified, used only for a short time or in an instant.
( 3 ) The flow meter should be operated under conditions of high pressure fluctuations and overload shocks. Therefore, it is necessary to switch the fuel ball valve and the fuel gun (connector) smoothly and slowly during use, and prevent the measured medium from flowing backward into the flowmeter.
( 4 ) When installing the flowmeter, the shaft of the waist wheel should be installed horizontally. The flow direction through the flowmeter should be consistent with the direction indicated by the arrow on the housing; the flowmeter should not be subjected to expansion, contraction, deformation, and vibration.
( 5 ) . The flow meter has a zero-return knob on the meter head . Before the work, check whether the count and pointer return to zero. After each refueling operation, turn the knob clockwise to return the hands and one count to zero. It is forbidden to move the pointer when the flowmeter is working.
( 6 ) In the pipeline system equipped with the flow meter, it is necessary to avoid generating or entering the air, otherwise the measurement will be inaccurate. Therefore, the flowmeter should be used when the entire system is full of oil.
