Tanker tanker used;

(1) on-board pump refiner Oil and temperature probe calibration is equipped with a filter, which consists of copper mesh and blankets mesh sets, separator side wall has a triangular cover can be removed filter. The filter of the combined pump refiner is installed in the inlet port. Submersible pump type tanker installed with a special filter box, open the end cap to remove the filter. The filter should be cleaned regularly (at least once a month) with gasoline to clean the copper mesh cover, damage should be replaced, and remove dirt from the oil machine to protect the pump and flow meter.
(2) on-board pump and the combination of the pump on the relief valve adjustment screw used to adjust the pump pressure, and then adjust the tanker's oil discharge. Factory has been adjusted. After long-term use, such as the amount of oil dropped, the adjustment screw can be tightened in order to increase the pressure of the pump, but not more than 0.3MPa, so that the amount of oil to meet the requirements.
(3) Combination of pump-type gasoline meter is only suitable for underground tanks, such as the use of high oil tank, there will be exhaust pipe oil phenomenon, then be sure to block the exhaust pipe.
(4) the use of oil guns to avoid the oil gun with the oil pipe percussion by oil containers, press the switch and other abnormal operation, so as not to damage the oil gun, causing oil spills. To check regularly, tighten the screw on the tubing to prevent the oil pipe root loose, damaged, underground storage tank regularly cleaned to keep the oil clean.
(5) the accuracy of the adjustment of the machine should be "JJG443-86 metering tanker test procedures," the relevant provisions.
(6) overhaul the electrical part of the power must be cut off, should not take electricity repair. Do not damage the explosion-proof surface when opening the explosion-proof case. When the explosion of dust inside the dust should be clean, the cable seal should be good, metal pads, gaskets can not be lost, the number of screws is not missing, tightened and reliable to ensure that the electrical components of the explosion-proof performance.
