A pump is a machine that converts the mechanical energy of the prime mover into liquid energy. Pumps can be used to increase the potential, pressure or kinetic energy of a liquid. Usually by the prime mover, that is, the motor and diesel engine through the pump shaft to drive the impeller to rotate, work on the liquid, so that the energy of the required amount of liquid is transported by the suction tank through the flow parts of the pump to the required high place or pressure place.
There are many types of pumps, the use is very wide, can be said to be general machinery, wherever there is liquid flow, there is a pump in the work, in addition, pumps in rocket fuel supply, ship propulsion and other aspects, is also widely used.
Oil gun is a tool commonly used to lubricate workshops and garages. The purpose of an oil gun is to apply lubricant to a specific location through a hole, usually on a grease joint or “grease nipple”. The passage behind the lubrication nozzle leads to where lubrication is needed. The aperture can be a type that closely fits the receiving aperture on any number of mechanical devices. The tight fit of the pore size ensures that the lubricant is only used where it is specifically needed. There are generally three types of oil injection guns.
The working principle of the filling pump is to complete the inflation of the inflatable cylinder through the continuous reciprocating movement of the plunger on the compressor. That is to say, the start motor and the motor rotate, drive the crankshaft on the compressor to rotate through the pulley, rotate the crankshaft on the crankshaft, drive the plunger up and down through the connecting rod and crosshead to reciprocate at both ends of the cylinder are equipped with one-way valves, that is, suction valves and exhaust valves, its role is to control the flow direction of the airflow, so the quality of the suction valve and exhaust valve has a significant impact on the inflation efficiency.
How to fill the pump with oil gun to fill the grease? First of all, you have to take the oil gun in your hand and unscrew it from the head by rotating the barrel counterclockwise. Then after unscrewing the head, you need to pull the follower lever back and make sure it is firmly attached at all times, so that the follower rod and plunger are all smoothly returned to the barrel. And then pick up the cartridge case, which has two sides. One is the plastic side and the other is the lid side. To prevent air bubbles, be sure to store the lid size of the grease cartridge downwards. After removing the lid, place the open side in the bucket and make sure it is firmly attached underneath. Secondly, pop the top, sometimes there may be some grease on the lid, which can be put into the bucket as well. Next, you screw the barrel to the head of the grease gun while making sure it is safe, then move it about half a circle to allow the air to escape. In order not to have cross-threads, check again that the threads are correct. Push the bleed valve immediately after that, while returning the follower lever to the gun. The meshing follower lever begins to move inside the barrel, while remembering to push the bleed valve. After it has all passed, do not forget to tighten the barrel. Finally, remove the cap from the piston and prepare it for lubrication.
