This is a strange installation, which can be done for very basic hydraulic needs where flow rate, direction and pressure are not necessary. On the other hand it should be understood that skipping valves means avoiding the normal safeguards and controls that make a hydraulic system flexible and safe. This is how to create such a setup.
Safety Precautions
First, safety is essential .Make sure all joints are tight and can handle the maximum pressure produced by your pump. When working with hydraulic systems always wear goggles or gloves as protective clothing. Clear the area of objects and people before testing the system.
Assembling Components
- Hydraulic Pump: The first component you will need for your system is a hydraulic pump from which you will derive your source of power. Ensure that you refer to the specifications of pump to ascertain its suitability for any specific application.
- Hydraulic Lines: Take high-pressurized hoses from departure point of the pump and connect them to cylinders or motors, which act like actuators in this case.
- Hydraulic Reservoir: Connect return line hitting back to hydraulic fluid reservoirs after being used up in actuators. It has breather cap relieving pressure at this level, which should be capable of accommodating entire mass of fluid during operation.
- Power Source: Link an electric motor, an internal-combustion engine or even another machine’s Power Take-off(PTO) to drive your hydraulic pump.
Filling and Priming
Fill the appropriate container with proper kind of oil then prime manually by purging air out from machine hence filling up both lines together with pumps before starting it up.
Initial Testing
Start running on power source so that pump may work circulating liquid via whole system; look at actuators in order to verify their correct movement characteristics.
Monitoring and Troubleshooting
The top most important thing here is that without valves there are no force control, directions speed control over acts occurring between actuator’s pistons and cylinders. Check for any leakage, abnormal sounds or erratic motion. Maintain the levels of hydraulic fluid in correct reservoirs.
Limitations
There are severe limitations to operating a hydraulic system without valves:
- The flow rate cannot be controlled, which means that you also can’t control actuator speed.
- Pressure cannot be relieved from the system leading to dangerous situations.
- Hydraulic fluid does not have an ability to change its course hence making actuators move in one direction all the time.
- Thus, most applications do not advise using valve-less hydraulic systems except for basic requirements or specific uses.
Conclusion
However simple it may seem, connecting a pump with no valves is a dangerous process that should only be done after one has well understood its limits and safety issues. Always seek advice from experts when considering such setup.
