1. Static grounding should not be ignored. From the tanker's point of view, the primary site of static electricity is the pump, the filter and the pipeline. The amount of static electricity generated by tanker filling systems is much higher than that of the above-ground pipelines. With respect to electrostatic hazards, it is necessary to adopt the following methods: 1 Connect the grounding cable before loading, and always check whether the absence of the grounding wire and the grounding resistance are in conformity with the anti-static standards. 2 When the oil is loaded, the crane pipe must extend to the bottom of the tank. The pipe mouth should be about 15cm from the bottom of the tank , and strictly control the filling speed at 1m/s until the oil outlet is submerged and gradually increase the flow rate. However, the maximum flow rate must not exceed 4.5m/s in order to eliminate the electrostatic discharge caused by the slopping. 3 After the oil is complete, it is necessary to disconnect the ground after 5 minutes of oil stabilization . Because after loading the oil, because the oil in the tank activities, so that the oil surface potential to adhere to a few minutes. 2. Avoid personal energization. During loading and unloading work, the human body must be in touch with the working target tank trucks and work objects to make contact with each other, which is very simple to cause static electricity, and can constitute electrostatic discharge. If flammable and explosive oil vapors happen at the moment, they will Onset of explosion. The operator must wear anti-static overalls and anti-static shoes during the operation. The intention is to ground the human body. In addition, the shoes worn should be thin nylon socks or other conductive socks. It is forbidden to put insulation film on anti-static soles and should be checked regularly. 3. Use equipment that meets technical standards and safety requirements. The automatic control, remote control, metering instruments, valves and other equipment of hair oil stations are subject to regular inspections and calibrations, and related management systems are formulated, especially for the raw materials of oil distribution equipment. Together with the electrostatic grounding device can not be, we must strictly follow the standard, careful installation, regular inspection. For the current use of clamps and magnetic joints grounded, should not be randomly caught or adsorbed in the random parts of the tanker , or even the appearance of the paint. This is a helium gas for the antistatic electrode, and it is a big danger. Many users are greedy for cheap when buying a car, but they don't know how to pay for it. The equipment is very simple and leads to troubles. It should pay more attention to dangerous goods vehicles such as tank cars . 4. trouble "means converting oil" should be configured to meet the focus. This kind of incident mainly takes place when using canned gasoline to store diesel fuel. The flash point of gasoline is lower than that of diesel. If diesel is written into a tank full of gasoline vapor, the gasoline vapor is absorbed by the dumped diesel. As the pressure is reduced, the air is sucked into the tank, and a flammable mixture is formed somewhere between the liquid surface and the air suction point. When the discharge is accumulated, the explosion event occurs. Therefore, when it is required to “ convert oil †, it is necessary to cleanse the gasoline in the tank first and strictly follow the operating procedures.
CNC milling machining is a CNC machine tool trajectory by means of computer controlled machine, using high speed rotating cutting tool if you want to shape the material. With the size of products have become increasingly demanding, machining from the original two gradually changed to 3 axis machining, 4 axis machining, 5 axis machining center, precision can reach 0.001mm. us the maximum machine processing size: 500mm * 1000mm *600mm, 800kg machine under the maximum weight of workpiece, Machine tool spindle speed 20000RPM to ensure that the surface of the workpiece is smooth and clean.we often processed material of aluminum,steel, copper, stainless steel, titanium, POM, Teflon and so on. At the completion of high quality, high dimensional accuracy of CNC milling machining parts process, we will divided into rough machining and processing method fine to get the best effect, the margin size coarse and finish machining is 0.5 * 1mm. after processing some of the products after surface treatment such as plating polishing surface passivation.Sand (powder), anodic treatment (aluminum common CNC anodized black red blue anode, anode, anode). CNC milling machining is widely used in aviation, automotive, communications, medical equipment, electrical appliances, drone.
