Practice of hydraulic system starting

 1. Monitoring.

- Check equipment. Hydraulic systems installed in more appropriate placements available for use as filters, pumps, pressure limit valve, directional control valves, cylinders, pipe joint, gas, pipeline and etc..

2. Refueling.

- Make sure the tank room was already clean and free from impurities other waste materials.

- Fuel oil as guides or qualified as a specification to fill the tank without telling than the highest rating.

- In the case of tank capacity does not tell level. The fuel quantity required.

- The fuel should be added via a specific device for a filter is installed.

3. The starting system

- Open the valve closed – open the oil suction pipe in the first case of the installation in it.

- Adjust the valve to limit pressure in the open position flows into the oil tank room at low pressure. Or near zero

- Check the direction of rotation of the pump with the correct direction of rotation of the powered device. (Electric motors, engines), the pump is starting to follow most carefully. Especially lubricating oil, usually based on hydraulic pump that uses the c starting first often in the worst condition. Due to lack of flow of oil Therefore necessary to add fuel to fully pump before starting pump first, and for pump adjusts the flow rate was (Variable Displacement) should start walking at low pressure will best part of starting electric motors, it should be done by using triggered moment to ensure that the oil shock occurred. Distinguishable from the sound of the pump has changed. If the pump does not work to stop sending oil pump hire immediately. To prevent damage inspection of the oil viscosity. More typical oil filter and remove the jam Pump see nothing inside the pump to speed up work will be to check the oil level is higher than said low limit.

4. Punching the air.

- Due to air in the system resulting in wear and high interfere with other, so it is necessary to chase air from the system out after the start operation by the chase through the exit tube fittings in the open that the highest position of the system. We can observe that the exhausted air from the system. Based on the oil that flows out continuously at the open pipe. No oil in tank foam No sound system disorders. And equipment work. (Cylinder or motor – Hydraulic A) is functioning correctly.

5. And the pressure for use.

- Set pressure limit valve (Relief Valve) or pressure compensation valve (Pressure Compensating Valve) in the pump flow rate was adjusted. To control the maximum pressure of the system to suit the work load. Based on internal pressure on the pressure gauge. Which generally come from areas of origin. The pressure read at the source should be greater than the pressure that occurs destination (Pressure work that occurs when cylinder or motor Hydraulic acrylic work driving or driving load is) not much, or may say that should set the pressure at the source rather than the pressure drop across arising from the flow of oil at the source end นั่นเอง in practice to ensure that While the cylinders or hydraulic motors driving a loaded work. Limit pressure valve or valve pressure compensation. Must be open so that the adjustment is considered appropriate.

6. The accumulated power control pressure tank. (Accumulator).

- Tank pressure should be controlled to successfully accumulate energy in the first week of operation and in case of no leakage If the control can work as usual every year I check once a year to check the gauge pressure of the hydraulic system, a collection tank connected to power directly The compression test fuel tank to accumulate energy and then gradually release the gas pump stops the accumulation of power cylinder pressure under control. Observation of the pressure gauge. Indicator will fall to zero as soon as the pressure in the tank to accumulate energy before compression pressure before compression pressure reading from the first position the needle will fall to zero.
