The hot summer has made our demand for frozen products more urgent, and the increase in temperature has made the preservation of most meat products even more inconvenient. In this case, the 4m 3t refrigerated truck has become the biggest demand for fresh seafood merchants. However, under such high temperature outdoor conditions, there may be a danger of spontaneous combustion when the vehicle is running for a long time. So, how can we avoid the emergence of spontaneous combustion? The first is to check if there is a short circuit in the 4m 3t refrigerated truck before departure. Because when the engine is working at a high temperature, the temperature of the ignition coil of the machine will increase. After long-term use, the insulating layer on the high-voltage ignition wire of the machine will also become softened, aged, and even Cracked. For the 4m 3t refrigerated vehicle at this time, the most likely is the leakage of electricity. So we must check the oldness of the vehicle at any time and check the details of the line. In addition, measures to avoid the high temperature and natural nature of a refrigerated truck can also be the maintenance of mechanical friction. We all know that if the surface area between the object and the object is too large, then the frictional index will increase, which may eventually lead to the appearance of a flame. Therefore, during daily maintenance, we can apply some lubricant to the engine of a 4m 3t refrigerated truck. The purpose is also to reduce the frictional heat during relative movement. The last point is the problem of parking. When we do not properly park our cars, the 3-ton refrigerated trucks we use may also have spontaneous combustion. Because when we use it for a long time, the exhaust pipe of the refrigerated truck must be in a state of high temperature. This is because if our parking is improper, it will make it easier to come into contact with flammable substances, then it may cause fire. Summer is the high season of fire. Therefore, when we use a 4m 3t refrigerated truck , we need to conduct a careful inspection and make a good circuit. Oil spill inspections are regularly sent to a regular maintenance shop for maintenance and maintenance. At the same time, fire extinguishers are prepared in the car to meet the needs of the occasion. Magnetic gear pump beed used to transfer many kind of oil and chemical liquid. pump have cast iron and stainless steel two kind of material. cast iron material pump also be used to transfer the lubricating oil, diesel fuel oil, engine oil etc oil. stainless steel material pump usually be used to transfer food grade oil or corrosive oil. pump with magnetic seal (magnetic seal) will have no leakage, more hygienic and safe. It's widely used in the food and chemical industries. it's a hot sales pump.
