The high-pressure pneumatic butter machine is a combination of an air pump and a plunger pump, which is called an oil-filling pump.
(1) The upper part of the oil injection pump is an air pump. The compressed air enters the air distribution chamber and passes through the air flow reversing devices such as sliders and slide valves, so that the air enters the upper end of the cylinder piston or the lower end of the piston, so that the piston can be automatically reversed within a certain stroke. Intake and exhaust, so as to make a reciprocating movement. 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 reciprocate synchronously with the air pump. There are two one-way valves in the plunger pump, one is sleeved on the lifting rod, which is called a four-legged valve disc and the lifting rod is used for axial sealing; the other is a nylon piston at the oil discharge port at the end of the plunger rod. The cone surface and the discharge valve seat are linearly sealed, and their work is to work back and forth synchronously with the oil injection pump. When the plunger rod moves upward, the nylon plunger is closed, the lifting rod is connected to the lifting plate to lift the oil up, and the oil pushes open the four-leg valve and opens upward into the pump; when the plunger rod moves downward, the four legs The valve is closed downwards, and the oil in the pump is squeezed by the plunger rod to open the nylon piston valve to drain oil again, so that the oil injection pump can generate high pressure for oil discharge as long as the oil injection pump reciprocates up and down.
(2) The oil storage cylinder is equipped with a rubber sealing piston, so that the oil in the cylinder can continuously press the piston to the oil surface under the action of the screw pressure, which can isolate the pollution and keep the oil clean.
(3) The oiling gun is a tool during the oiling operation. The high-pressure oil discharged from the pump is transported to the gun through the high-pressure rubber tube, and the nozzle of the gun directly kisses the required oiling point. Pull the trigger and inject the oil into the required oil. part.
