  As a special transport vehicle, refrigerated box trucks must check the precautions before driving to prevent unnecessary troubles during driving. It is recommended to carry out the following inspections before each loading and driving: 1. The fuel supply of the refrigerated truck must be sufficient to keep the engine running at least until the next checkpoint. 2. The engine oil level of the refrigerated truck is supplied at the full mark, do not overfill (replace once a year). 3. Refrigerated truck coolant, check the coolant level gauge to see if the coolant volume is correct, and the pointer should be within the white range. If the coolant level is within the red range, add coolant to the coolant tank. Usually the coolant is a mixture of ethylene glycol and water (different ratios are used according to the actual situation of the product), and it should provide protection from freezing at -34°C. Note: Do not open the lid of the coolant tank when the coolant is hot. 4. T...

 The vacuum suction truck uses a vacuum pump to evacuate the tank and then uses atmospheric pressure to press sewage into the tank. Normally the vacuum suction truck will be equipped with an anti-overflow valve. The anti-overflow valve can prevent the tank from being pumped to a certain extent. But because the principle of the anti-overflow valve is to connect the air inside and outside the tank after being floated by the sewage, so that the air pressure can be balanced, and the vacuum environment can be destroyed to prevent the full suction effect. There is no sound in actual use. If you do other things and don’t pay attention when suctioning sewage, it will lead to flooding. Because after the anti-overflow valve of the sewage suction truck is opened, it will take time for the air pressure inside and outside the tank to balance, about a few seconds. It may have filled the tank in a few seconds. And if it is working at high power, the air flowing into the tank from t...
