Common faults and countermeasures of electric grease gun

The electric grease gun is a miniature electric grease gun, which consists of a casing, a frame, a plunger pump mechanism, a crank-slider mechanism, a gear reduction mechanism, an oil supply system, an operating system and a power system: its structure is small and the battery is built-in, An external charger can be installed, driven by a DC motor, the price is moderate, labor-saving, fast, easy to operate, high pressure, and can meet the general mechanical oiling requirements.
major failure
First, the leather bowl is not good. This is a common problem with almost all domestic oil guns. However, it is no wonder that the structure of an oil gun is more complicated than that of ordinary tools. It can only be sold for a dozen yuan. Bar;
The second is that the oil pressure mechanism is not good, but if there is no problem with the spring and the non-return steel ball, it probably cannot be repaired.
The third is some faults in use. Many of the faults in use are caused by their own operations, and you can find ways to avoid them. For example, sand, once a few grains of sand are mixed into the butter, and you are using a pointed grease nozzle, it is guaranteed that you will be so angry that you have to throw the grease gun to relieve the hatred, and it is absolutely useless for the equipment. However, Most of this is actually self-inflicted. Therefore, it is necessary to keep the butter used clean, do not use unclean tools to refuel, and cover the oil container in time.
Responses
1. If there is a hard pull rod, you can pull the rod several times so that the air inside can be mixed with the grease, reducing the volume of a single bubble may solve the problem, but the effect is not very good every time.
2. The most effective method is the deflation method, but this requires the support of hardware. Some gun bodies have an exhaust port design. When you slowly open the exhaust screw, the air inside will come out.
3. The last one is the ultimate skill, and it has been tried and tested repeatedly. When you feel that there is gas in it and you can't shoot it out, you just need to turn the wire port that combines the oil gun body and the pump body a few times or back and forth a few times (preferably the side Turn and press) to ensure your success. The reason is not difficult, that is, when you rotate, the gas bubble inside is actually rotating to another part, and the original part is filled with lubricating oil, so the problem is solved.
