Abstract
The utility model discloses a mobile type pneumatic oil feeding pump, which pertains to the technical field of oil pipe design and manufacture. The oil pump consists of an air way reversing valve, an air cylinder and an oil storing tank. Wherein, the air way reversing valve consists of a sliding valve and a scavenging air valve; the air way reversing valve is positioned on the upper cover of the air cylinder, and the oil storing tank is jointed on the lower cover of the air cylinder. The utility model is integrated through a pushing and pulling rod, piston rod, and an oil suction pipe. The air reversing valve is fixed on the left valve of the air way reversing valve, and also consists of a sliding plate, a big sliding block and a small sliding block. The sliding block is provided with three pairs of small ducts, a couple are communicated with the sliding valve, the second group are connected with an air releasing window and the last one group are connected with the lower cover of the air cylinder. The compressed air pushes the bottom of an aluminum piston through the lower cover of the air cylinder, and pushes further the big and small sliding blocks so as to reverse the directions of the air feeding and releasing for the upper and lower cavities of the air cylinder. The pushing and pulling rod and the piston rod drive the upper line of oil releasing valve oil feeding piston and the lower oil releasing valve to vertically move. The oil is drew off through the oil drawing hole and then is released out through the upper oil releasing valve, and finally is conveyed to the oil feeding machine through an oil releasing sprayer. The utility model has the advantages of simple structure, reasonable design, smaller volume than the present product, light weight, energy saving and excellent oil releasing effect, etc.
