Pneumatic grease gun oiling machine working principle
Pneumatic butter machine, is connected by the air pump piston pump as one of the oil pump, by the butter storage tank, oil gun, high pressure rubber hose, quick change joints and other components. First, the upper part of the oil pump for the air pump, from the compressed air into the distribution room through the slider, slide valve and other air reversing device, so that the air into the cylinder piston or piston at the bottom, to achieve a certain stroke in the piston automatically Gas and exhaust, so as to reciprocate movement. The lower part of the oil pump is a plunger pump, its power from the air pump, the two connected by the connecting rod, synchronized with the air pump reciprocating motion. Piston pump has two one-way valve is set on the extraction rod is called the four-legged valve and the rod to make axial seal; another plunger rod at the end of a nylon piston, Cone and discharge valve seat linear seal, their work is synchronized with the oil pump from the work. When the plunger rod moves upward, the nylon plunger is closed, the lifting rod is connected with the lifting plate to raise the oil upwards, and the oil is pushed up to open the four-leg valve to enter the pump; when the plunger rod moves downward, The valve is closed down, the pump oil by the plunger plunger to open the nylon piston valve again row of oil, so that the oil pump as long as the reciprocating action, you can make the oil to produce high pressure to get oil. Second, the storage tank is equipped with rubber seal piston, the cylinder of oil in the screw under the pressure of the piston will continue to pressure to the oil, to isolate pollution to keep the oil clean.
The oiling gun is a tool during the oiling operation. The high pressure oil discharged from the pump is sent to the gun through the high pressure rubber tube. The gun nozzle is directly kissed with the required oiling point, and the trigger is injected into the required area.
The compressed air drives the pneumatic motor to drive the plunger to reciprocate the output of the butter
