The high-pressure pneumatic grease pump is an air tool that is connected with a plunger pump by an air pump, and is also called an air powered grease pump. Air operated grease pump machine is composed of grease storage tank, air grease gun, high pressure grease hose, quick change joint and other components.

• The upper part of the oil injection pump is an air pump. After the compressed air enters the air distribution chamber, the air enters the upper end of the cylinder piston or the lower end of the piston through the air flow reversing device such as the slider and the slide valve. Then the piston automatically enters and exhausts within a certain stroke, thereby making reciprocating motion.
• The lower part of the oil injection pump is a plunger pump. Its power comes from the air pump. The two are connected by a connecting rod and move synchronously with the air pump. There are two single valves in the plunger pump, one of which is sleeved on the lifting rod, called a four-angle valve, which is axially sealed with the lifting rod. The other is the nylon piston at the oil discharge port at the end of the plunger rod, which is linearly sealed with a tapered surface and a discharge valve. Their function is to work synchronously with the injection pump. When the plunger rod moves upward, the nylon plunger is closed, and the lifting rod is connected to the lifting plate to lift the oil up, and the oil is pushed open the four-corner valve to open up and enter the pump. When the plunger rod moves downwards, the four-corner valve closes downwards, and the oil in the pump is squeezed by the plunger rod to open the nylon piston valve to drain the oil again. As long as the oil injection pump reciprocates up and down, the oil can generate high pressure to discharge oil.
• The oil storage cylinder of the pneumatic drum grease pump is equipped with a rubber sealing piston, so that the oil in the cylinder will continuously press the piston to the oil surface under the pressure of the screw rod, which can isolate the pollution and keep the oil clean.
• The grease gun of the air pressure grease pump is a tool during the grease filling operation. The grease injection gun transports the high-pressure oil discharged from the pump to the gun through the high-pressure grease hose, and the nozzle of the grease gun directly contacts the required oil injection point, and the oil can be injected into the required part by pulling the trigger.
