Abstract
The utility model discloses an energy-conserving oil feeding system, including oil tank, oil hydraulic cylinder, the oil feed way is equipped with between oil tank and oil hydraulic cylinder, and the oil pump passes through the servo motor drive, and for the fluid pressurization in the oil feed way, servo motor can adjust operating power according to real-time oil pressure, provides stable oil pressure, avoids extravagant electric power, reduces oil feeding system's energy consumption, reduction in production cost.
Description
Technical Field
The utility model relates to an oil supply field especially relates to an energy-conserving oil feeding system.
Background
In the existing oil supply system, an oil pump is controlled by a motor to pump oil into an oil pressure cylinder, and a piston in the oil pressure cylinder is pushed by oil pressure to start working of the piston, but the power of the motor is kept unchanged all the time.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides an energy-saving oil supply system.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an energy-conserving oil feeding system, includes oil tank, oil hydraulic cylinder, the oil tank with even there is the oil feed way between the oil hydraulic cylinder, even there is the direction valve on the oil feed way, the direction valve pass through return oil way with the oil tank intercommunication, the oil feed way pass through the oil pump to oil hydraulic cylinder pump oil, the oil pump passes through the servo motor drive, be equipped with oil pressure monitoring devices on the oil feed way, oil pressure monitoring devices electricity links to have P L C, P L C control servo motor.
Preferably, the oil pump is an internal gear pump.
Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic diagram of the present invention.
Detailed Description
Referring to fig. 1, an energy-saving oil supply system comprises an oil tank 1 and an oil hydraulic cylinder 2, wherein an oil supply path 3 is arranged between the oil tank 1 and the oil hydraulic cylinder 2, an oil pump 6 is driven by a servo motor 7 and used for pressurizing oil in the oil supply path 3, and the oil pump 6 adopts an internal gear meshing pump; the pressure required for pushing the piston in the oil hydraulic cylinder 2 is P1The oil pressure in the oil supply path 3 is monitored in real time by the oil pressure monitoring device 8 on the oil supply path 3, and the pressure value is fed back to the P L C9, when the real-time oil pressure is lower than the P1In the time, the P L C9 controls the working power of the servo motor 7 to be increased, so that the oil pump 6 increases the pressure of the oil liquid, and the oil pressure is increased to P1So that the oil can push the piston; when the piston is required to maintain the pressure P during the production process2When the pressure in the hydraulic cylinder 2 needs to be maintained, the hydraulic monitoring device 8 monitors the oil pressure in the oil supply passage 3 in real time, and the servo motor 7 is controlled to maintain the output power by P L C9 so that the oil pressure is maintained at P2When the oil pressure monitoring device 8 monitors that the oil pressure fluctuates, the pressure value is fed back to the P L C9, the P L C9 controls the servo motor 7 according to the real-time oil pressure, if the oil pressure decreases, the output power of the servo motor 7 is increased, and the oil pressure is increased to P2And maintaining that, if the oil pressure rises, the output power of the servo motor 7 is reduced to reduce the oil pressure to P2And maintain(ii) a Make servo motor 7 in this oil feeding system can come the adjustment operating power according to real-time oil pressure, provide stable oil pressure, avoid extravagant electric power, reduce oil feeding system's energy consumption, reduction in production cost.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
