美國*KIMRAY高壓調(diào)節(jié)器/凱姆鐳電液動執(zhí)行器  電液動執(zhí)行器Electro Hydraulic actuatorINTRODUCTION
As requirements for low emission processes make your job more difficult, Kimray has a solution. Using our rich experience in the oil and gas industry, we have developed the Kimray Electro-Hydraulic Actuator. Using a high efficiency hydraulic pump, you can now actuate your valves with no emissions. And with a small solar panel, this solution becomes self contained and energy independent. This can be used with any size Kimray topworks, or and spring return topworks requiring 30 psi to actuate.
美國*KIMRAY高壓調(diào)節(jié)器/凱姆鐳電液動執(zhí)行器 OPERATIN G PRINCIPLE
For all versions of the EHA, hydraulic oil is shuttled from the area on top of the diaphragm to the area underneath the diaphragm through a manifold. For a Pressure Opening (PO) valve the volume on the top of the diaphragm acts as a storage space for hydraulic oil at atmospheric pressure. The volume underneath the diaphragm is pressurized to actuate the valve open. An oil reservoir is attached to the top of the valve actuator to allow for hydraulic oil input and visual measurement of the hydraulic oil level. The EHA can be used with either a pressure to open valve or a pressure to close valve. When a signal is received through the control
circuit to open a PO valve, the pump is activated and begins to move and pressurize the hydraulic oil out of the top of the diaphragm space and into the volume underneath the diaphragm. The valve actuator begins to open the valve.
For the Discrete (ON/OFF) version, the pump continues with pressure being monitored by the pressure transducer until the maximum set point is reached. At that point, the pump is deactivated and the valve remains open. The Discrete version does not have position feedback. Two discrete inputs (such as a GEN II electronic level controller) are monitored for operation. The first discrete input notifies the controller to begin opening the valve by changing from an open contact to a closed contact. The second discrete input notifies the controller to begin closing the valve by changing from an open to a closed contact.
