Dongfeng tank trucks are generally rigorously inspected before being shipped from the factory. After the tank is formed, the workshop conducts airtight tests. After the completion of the subsequent vehicle assembly, there will be a test of water test. After the finished products are shipped out, the Technical Supervision Bureau will inspect and issue the test. Tank inspection report. In general, there are no quality problems in the tanks within a few years after they are shipped from the factory. Basic problems that are prone to problems are consumables. Summarized the 17 issues that should be paid attention to in daily maintenance of oil tankers.
1. The carrying part of the oil tank, popularly known as the car chassis. The general driver is more knowledgeable about this piece. The problem is that after the oil tanker installed the oil pump, we installed the drive shaft and power take-off device from the engine. With these two devices, we need special attention during operation. The device is scrapped.
2. The use and maintenance of the oil pump should be performed strictly in accordance with its instructions for use and maintenance.
3, the use and maintenance of tanker, please strictly follow the instructions for use, with the car are equipped with instructions.
4, the oil slowly, no oil, please check the safety valve, filter network. These should be checked and cleaned frequently.
5, tanks and piping systems should be cleaned regularly. Regularly check whether the joints of the pipeline system are well connected and the seal is reliable.
6. In order to ensure the cleanliness of the oil tank, the oil tank and the oil delivery system should be cleaned regularly. The internal and external joints at both ends of the oil hose should be lubricated with oil. It is easy to disassemble and disassemble. After each time the tubing is completed, cover the inlet and outlet end caps (caps) and the ends of the oil hoses (caps) to ensure that the tubing is clean.
7. The oil loading should not exceed the rated loading quality. (According to oil density conversion).
8, the ball valve through the medium should not be dirty, to protect the seal ring, improve the service life of the ball valve, the ball valve should not be long-term in the semi-closed state, otherwise easy to make the seal ring deterioration, in the driving of the ball valve handle should be in Disabled.
9, the pump network should be frequently dismantled and cleaned to prevent the oil residue blocking the filter screen, affecting the flow.
10, should keep the breathing valve clean, so that the breathing valve is in working condition, the spring in the valve can not be arbitrarily changed, so as not to affect the effect of suction, deflation. When the breathing valve is blocked, there is a danger of deforming the tank.
11. In order to prevent the oil tanker from a fire accident, parts of the oil tanker are not allowed to be hit with metal objects when the exhaust pipe, muffler is damaged, the pipeline leaks, the lead electrode is broken or broken, so as to avoid the generation of Mars, the oil tanker Fire equipment should be ready at all times.
12. If the sediment tank under the oil tank freezes, do not bake it with fire, use the hot steam to melt it, or open the car into the warm room to thaw it.
13. Before the refueling truck is operated, it must be inserted into the damp soil using a lightning rod. The grounding tape should be grounded, and the static conduction should be maintained during the operation.
14. Examine the fire extinguisher device before leaving the vehicle. Users of the fuel tanker should be familiar with the use of the fire extinguisher and inspect and maintain it in accordance with its instructions for use.
15. Before the tanker works, check whether the pipeline system leaks oil, if the grounding wire is disconnected, and if the exhaust pipe is damaged, find out that the problem should be resolved before operating.
16, when the amount of oil should be implemented in accordance with relevant regulations. In winter, if there is water in the self-priming pump, the water must be drained to prevent freezing of the pump body.
17. When working in the oil tank, attention should be paid to good ventilation, and there must be protection outside the tank. If necessary, wash the tank with soapy water before proceeding.
