1, pneumatic grease gun
The working principle of grease gun is basically the same, and the difference between different grease guns is mainly the difference of power source. Pneumatic grease gun is suitable for lubrication system and complete butter shunting equipment. Super-large cylinder design can improve the oil delivery pressure and oil output, which is suitable for high viscosity grease and cold areas. It can also be equipped with a mobile electric lubricating device consisting of a mobile trolley, a hose and an oil gun, which is specially used for the mobile lubricating oil supply of a single device with low lubricating frequency, few lubricating points and large oil supply, and it is inconvenient to adopt centralized lubrication. Widely used in mines, ports, power plants, production workshops and other occasions.
2, pedal grease gun
The ergonomic design of the operating mechanism of the pedal butter machine is compact and reasonable. This product is safe, reliable, light, labor-saving and easy to move. Suitable for filling grease in metallurgy, ports, automobiles, construction machinery and various places without gas source.
3. Electric grease gun
The electric grease gun directly uses 220V/380V power supply without compressed air, which is convenient, fast and energy-saving. Its advantages are low noise, stable working pressure, high production efficiency and low labor intensity. Adopt precision pressure relay control circuit and grease gun switch, the motor is also powered off to protect the motor and seal, and the output pressure can be adjusted according to your needs. It is suitable for pressure regulating valves with many lubricating points and wide distribution range, and has the advantages of stable and reliable operation, convenient displacement derivation, compact structure, small vibration and low noise. According to the need, a capacity indicator can be arranged in the oil tank, and the corresponding electric control box can realize automatic operation.
4. Manual grease gun
Manual grease gun injects grease into the lubrication part of beam pumping unit by using the pressure rod grease gun, which is characterized by light and simple equipment and convenient use. The disadvantage is that workers are labor-intensive and easily tired, which seriously affects work efficiency.
Second, the correct use of grease gun
With the fierce competition in the market, the styles of grease guns are becoming more and more diversified, but the basic principles of grease guns are similar. The nozzles are divided into two types: sharp nozzles and flat nozzles, and the accessories are also hoses and hard pipes. The general structure of grease gun is composed of gun head, barrel, handle and handle, and the interior is composed of leather cup, spring, steel ball, pull rod and exhaust screw. On the surface, everyone is diverse. The grease guns appearing on the market now are generally prone to problems such as oil leakage, sand feeding and oil pressure failure, which is also the most headache for users. One reason is the problem of the grease gun itself, and another reason is that some of them are novices and don't know much about the use of the grease gun. Improper use of grease gun due to operational error. In view of some faults in use. We can avoid it as much as possible, such as checking whether the grease nozzle on the machine is intact before refueling, and choosing a grease manufacturer with a bigger brand first. Once no grease is selected, the best grease gun will quickly decompose the machinery. So be sure to keep the nozzle of the butter gun clean, don't use unclean tools to refuel, and cover the oil container in time. In addition, you can go to the screen window shop to ask for some yarn, cut it into the size of the gasket in the grease gun cover with scissors, put it in the grease gun cover, put a few pieces of butter on it, and you can look at the screen. This method is very useful. Another fault in use is that the oil cannot be pressed out. Actually, it's just our oil gun with air. I wonder how many inexperienced novices are at a loss because of this small mistake.
If it is hard butter, you can use suction refueling (be careful not to look at the instructions and expect to suck the oil up, but push it down with the gun shell when the pull rod is relatively static, with no gap in the middle); If the oil is soft, you can take a shovel and fill it up. Never fill the jar, but leave a passage while adding it, so that when you throw oil by hand, the air inside will come out (of course, throwing oil by hand is also a good choice). Some refueling skills are mentioned above, but in actual use, there may still be air inside, which is not easy to refuel. At this time, some targeted measures should be taken.
Troubleshooting of manual grease gun
1. If you have a hard pull rod, you can pull it several times to mix the air and grease inside, and reducing the volume of a single bubble may solve the problem, but the effect is not good every time.
2. The most effective method is deflation, but it needs the support of hardware. Generally, the gun body has an exhaust port design. When you slowly open the exhaust screw, the air inside will come out.
3. When you feel that there is gas in it and you can't pump it out, turn the joint between the oil gun body and the pump body several times or back and forth several times (it is best to press while turning) to ensure your success.
