Description

Oil pipe resistance measuring device for oiling machine Technical Field The application relates to the technical field of oiling machines, in particular to an oiling machine oil pipe resistance measuring device. Background In fuel dispenser systems, the fuel dispenser tubing is typically made of metal (e.g., stainless steel) or a composite material that is well conductive. The metallic material itself has a certain resistivity. The electrical resistance of the oil pipe is an important electrical parameter, which is not only related to the electrical safety performance of the oiling machine, but also can influence the generation and release of static electricity in the oiling process, thereby influencing the safety of the oiling operation. The tubing serves as a passage for fuel delivery and is part of the electrical circuit. If the oil pipe has excessive resistance, more heat can be generated on the oil pipe according to Joule's law when current passes through the oil pipe in the oiling process. This heat may cause the temperature of the oil pipe to rise, and even cause safety accidents such as fire. In addition, excessive tubing resistance may also affect the effectiveness of the grounding system of the fuel dispenser. The grounding system has the function of timely guiding static electricity and leakage current on the oiling machine to the ground, so that the electrical safety of the oiling machine is ensured. If the oil pipe resistance is too large, the grounding resistance is increased, the performance of the grounding system is reduced, static electricity and leakage current cannot be released in time, and the risks of static electricity accumulation and electric shock are increased. At present, the resistance measurement of the oiling machine oil pipe adopts a multimeter method to measure, when production operation, two workers mutually cooperate, one worker holds two ends of the oil pipe to fix, the other worker holds probes at two ends of the multimeter to measure, when the multimeter probes are contacted with two ends of the oil pipe, the multimeter can apply current to the oil pipe to conduct, further the resistance is measured and displayed, and then the manual reading and the resistance measurement result recording are carried out.
