Structure and function of manual hydraulic oil pump

Manual hydraulic pump station Introduction <br> <br> manual hydraulic pump is manually mechanical energy into hydraulic energy of a small hydraulic pump station.

In the case of the use of supporting oil cylinders and special tools, various operations such as lifting, bending, straightening, shearing, riveting, assembly, disassembly, construction and military construction can be carried out. The main features of the oil pump are: high pressure, manual, ultra-small, easy to carry, simple operation, and wide application range.

The main structure and function of the manual hydraulic pump <br> <br> manual hydraulic pump portion by each of the following components: 1, the body part; 2, the handle portion: 3, the hose part; 4, storage tanks; 5, Seating part.

1. Pump body: The pump body is the main part of the pump, high pressure working chamber, low pressure working chamber, two one-way valves, high pressure valve (safety valve), low pressure valve, unloading valve, two check valves, and oil inlet Mouth and so on are above. Holes are organically linked. The two one-way valves prevent pressure oil from flowing back, and their specifications and functions are the same. The role of the low pressure valve and the high pressure valve is pressure control, controlling the pressure to 1Mpa and 63Mpa, respectively. The two steel balls at the inlet are check valves. After the work is completed, the unloading valve is opened, and the pressure oil flows back to the oil storage pipe to complete the unloading work.

2, handle part: mainly by the pressure rod, pressure handle composition. Connect two pins to the pump body and plunger. Hand dynamics act on the pressure rod to drive the plunger to reciprocate and generate the pressure of the oil. There is M20×1.5 screw hole on the pressure handle, which is used for the vertical installation of the pressure rod. You can choose vertical or horizontal position operation according to the convenience of operation.

3, the hose part: It is the part that connects the oil pump and the oil tank to convey the pressure oil. When not in use, the hose is disconnected from the cylinder, the head of the hose is plugged with a rubber cap, and the connector of the cylinder is plugged with a connector to prevent dirt from entering the tubing and the cylinder.

4. The oil filling and air evacuation device is installed on the rear seat or the oil tank. When the oil pump is working, the air screw must be loosened to avoid generating negative pressure in the oil storage tank and affect the normal work. After the work is completed, tighten the air screw. Install a hook on the back end and use a hook to lock the lever when carrying the oil pump.
