Stone Construction Machinery Co., Ltd. Jining to introduce you to run a small hydraulic crane

1. First, you have a tank containing hydraulic oil, hydraulic oil supplied to the pump.
(2) Next, the form must have a pump oil flow, but small crane pump oil from the tank can not. Gravity causes the oil into the pump.
3. Small crane pump each rotation, it will release the oil. An important point to remember is to just move the pump capacity. Hand pallet jacks capacity determines the speed of movement. Load the formation pressure, small crane pump does not generate pressure.
4. Small crane pump and control valve connected between the pipes. Small crane pump out the oil flow to the valve. Valve's task is to make the oil flow to the cylinder or tank.
5. The next step is the fuel tank system, the fuel tank for the actual work. There are two tubing connecting the control valve cylinder.
6. Small crane pump out the oil flow through the control valve piston at the bottom of a large cavity. Load flow resistance generated and shaped raw pressure.
7. System seems to be very complete, in fact, still incomplete. It also requires a very important part. We must consider suddenly overloaded or other fault in the case of the protection of all the components from damage. Even if the system fails, the pump continues to turn to the oil supply system. If the pump out oil with nowhere to go, the pressure will accumulate until some of the parts are damaged. We mount a relief valve to prevent damage. Often, it is turned off, but the pressure reaches the set amount, the valve will open and allow the oil tank.
8. Small crane tanks, pumps, control valves, cylinders, connecting piping and pressure relief valve consisting of the basic hydraulic system. All of these components are required. Now that you have a clear understanding of the working process of the hydraulic system
