The refueling gun of vehicle mounted refueling machine is an important tool for refueling, and most users don't know much about it, let alone how to maintain it
Structure of refueling gun of tanker:
① The switch handle of regular oil dispenser is equipped with a baffle. With the help of the limit plate, the switch handle of oil dispenser can be placed in three different gears, so that the main valve of vehicle mounted oil dispenser can be placed in three corresponding opening degrees, so that we can get different flow when using vehicle mounted oil dispenser.
② The outer surface of the nozzle of the refueling gun is equipped with springs, so that when we refuel, the gun can be placed in a certain position of the container, and it is not easy to slip off, contaminate the refueling gun, or even contaminate the oil.
③ Generally, there are three holes evenly distributed along the circumference at the upper end of the automatic control rod of the refueling gun of the refueling machine, and three steel balls are installed in the three holes. Lift the switch handle, and the three steel balls will block the automatic control rod by the inclined plane on the gun body, so as not to make the automatic control rod move downward; when the self sealing rod moves upward, the steel ball will close to the center of the automatic control rod, so as to make the automatic control rod move downward and close the main valve.
The above are the main parts and structure of the regular refueling gun. After we are familiar with the main structure of the refueling gun, it is more conducive for us to maintain the refueling gun.
Maintenance of refueling gun of refueling machine:
① In order to prolong the service life, lubricating oil should be often added to the top rod of the refueling gun;
② The O-ring at the lower part of the top rod of the refueling gun and the steel ball, self sealing rod and switch diaphragm of the self sealing gun should be inspected regularly. If it is found that it is not easy to use, it should be inspected at any time for maintenance and replacement;
③ When using the refuelling gun, it is necessary to avoid incorrect operation such as knocking the oil receiving container and pressing the switch with the refuelling pipe of the refuelling gun. This kind of operation can easily damage the root of the refuelling pipe, causing oil leakage and disconnection;
④ Irregularly check and tighten the screw on the filling pipe of the refueling gun of the on-board refueling machine.
The above is the structure and maintenance method of on-board refueling machine refueling gun of on-board refueling machine. Users can pay attention to understand, check and maintain their own refueling gun when using and operating on-board refueling machine, so as to ensure the accuracy of their own on-board refueling machine.
