Embodiment Construction

[0007] The scheme of the present invention integrates the oil tank and the pump body, and the plunger rod, the oil inlet and outlet pressure limiting valves and the oil circuit are placed inside the oil tank, and the pressure difference between the pump body and the outside is formed by the lifting of the plunger, and the oil is released. The oil is sucked into the oil tank from the oil inlet, and then the oil in the oil tank is discharged from the oil outlet through the extrusion of the plunger, thus forming an oil supply cycle.

[0008] Combine below figure 1 Describe in detail the details and working conditions of the specific device proposed according to the present invention.

[0009] The device mainly includes handle part 1, plunger rod part 2, pump body 3, pressure limiting valve a4, screw plug a5, screw plug b6, screw plug c7, oil outlet nozzle 8, pressure limiting valve b9, fuel tank 10, Oil inlet nozzle 11.

[0010] Wherein the pump body 3 is equipped with a total ...

Abstract

Disclosed is a small oil supply device with an oil tank and a plunger pump. Three oil circuits are arranged in the oil tank, are connected with an oil inlet, an oil outlet and a plunger rod movement chamber correspondingly, and communicate with one another. A pressure limiting valve a and a pressure limiting valve b are installed in a pump body, the pressure limiting valve a is installed in oil inlets of the oil circuits, and the pressure limiting valve b is installed in oil outlets of the oil circuits. An oil outlet pipeline connecting nozzle and an oil inlet pipeline connecting nozzle are installed in an oil outlet and an oil inlet of the pump body. A handle component and a plunger rod component are connected with each other, the handle component is fixed to a handle base of the pump body in a threaded connection mode, and the handle component is shaken to drive the plunger rod component to move. According to the small oil supply device, the oil tank and the pump body are integrated,the size is small, the space is greatly saved, the oil filtering function is fulfilled, installation is convenient and fast, the oil supply efficiency is improved, and the oil supply amount is increased.

Description

technical field [0001] The invention belongs to the field of hand pumps for oil supply of hydraulic systems in airplanes and helicopters, in particular to a small plunger pump oil supply device with an oil tank. Background technique [0002] At present, domestic hand-operated plunger pumps are commonly used hydraulic components in aircraft hydraulic transmission systems. Traditional hand-operated plunger pumps need to be equipped with an additional fuel tank, connected to the fuel tank through oil pipes, and have defects such as low fuel supply efficiency and low fuel volume. Contents of the invention [0003] The purpose of the present invention is to provide a small plunger pump oil supply device with an oil tank, which integrates the oil tank and the pump body, is small in size, greatly saves space, has its own oil filtering function, and is easy to install, improving the oil supply. efficiency and fuel delivery. [0004] The technical solution to realize the purpose o...
