Description

A kind of vulcanizer without sensor servo drive system
Technical field
The utility model relates to vulcanizer technical field, be specifically related to a kind of vulcanizer without sensor servo drive system.
Background technology
Energy-saving vulcanizer is made up of injecting systems, Clamping System, electric control system, lubricating system, temperature control system, safety monitoring system and servo drive system usually.Wherein, servo drive system is part comparatively crucial in whole device, along with the development of science and technology, the servo drive system of existing energy-saving vulcanizer generally adopts closed loop feedback to control, and does feedback signal by pressure sensor and the velocity sensor be installed on servomotor of detection system oil pressure to servo-driver.
Due to the increase of sensor, cause system destabilizing factor to increase, often because sensor fault causes vulcanizer to stop producing, cause economic loss; And because system adds the sensor control circuit of sensor and coupling, result in energy-saving vulcanizer cost higher.
Summary of the invention
The purpose of this utility model be in order to overcome prior art exist deficiency, provide a kind of vulcanizer without sensor servo drive system.
The utility model is achieved through the following technical solutions: a kind of vulcanizer without sensor servo drive system, described vulcanizer without sensor servo drive system by controller of vulcanizer, servo-driver, servomotor, oil pump, oil cylinder, proportional pressure valve, reversal valve, overflow valve, fuel tank forms, described servo-driver output interface is electrically connected with proportional pressure valve, the flow signal of described controller of vulcanizer is electrically connected with servo-driver, the fuel injection pressure signal of described controller of vulcanizer is electrically connected with servo-driver, described servo-driver built-in signal comparator, the signal comparison other of described signal comparator is servo-driver output current and fuel injection pressure signal, described servo-driver is by signal comparator running mode switching, described servo-driver operational mode is respectively velocity mode and oil pressure pattern, when described signal comparator detects that servo-driver output current is greater than fuel injection pressure signal, described servo-driver presses oil pressure mode operation, when described signal comparator detects that servo-driver output current is not more than fuel injection pressure signal, described servo-driver is pressed velocity mode and is run.
The signal type that described servo-driver output interface is electrically connected with proportional pressure valve is direct current 0-1A current signal.
Described servomotor is Speedless sensor type.
Described servo-driver is in velocity mode when running, and the described oil pump speed of service is per minutely be greater than 200 turns.
When described servo-driver is in oil pressure mode operation, described oil pump slows down as 0 turn per minute.
Described oil pump is gear pump or plunger displacement pump or screw pump.
The beneficial effects of the utility model are: the utility model adopts without sensor servo drive system, the signal comparison other of signal comparator is servo-driver output current and fuel injection pressure signal, servo-driver is by signal comparator running mode switching, due to without the need to pressure sensor and velocity sensor and corresponding match circuit, this servo drive system stability obviously increases, and simultaneity factor cost can significantly reduce.
Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, vulcanizer without a sensor servo drive system, being made up of controller of vulcanizer, servo-driver, servomotor, oil pump, oil cylinder, proportional pressure valve, reversal valve, overflow valve, fuel tank without sensor servo drive system of described vulcanizer.
Servo-driver output interface is electrically connected with proportional pressure valve, the flow signal of controller of vulcanizer is electrically connected with servo-driver, the fuel injection pressure signal of controller of vulcanizer is electrically connected with servo-driver, servo-driver is electrically connected with servomotor, servomotor is connected with oil pump, oil pump is connected with reversal valve, reversal valve is connected with oil cylinder, overflow valve is connected with oil pump, overflow valve is connected with fuel tank, and proportional pressure valve is connected with fuel tank, and proportional pressure valve is connected with oil pump, proportional pressure valve is connected with reversal valve, and reversal valve is connected with fuel tank.
Servo-driver built-in signal comparator, the signal comparison other of signal comparator is servo-driver output current and fuel injection pressure signal, servo-driver is by signal comparator running mode switching, and servo-driver operational mode is respectively velocity mode and oil pressure pattern.
When signal comparator detects that servo-driver output current is greater than fuel injection pressure signal, servo-driver presses oil pressure mode operation, when servo-driver is in oil pressure mode operation, described oil pump slows down as 0 turn per minute, simultaneously, servo-driver provides signal and drives proportional pressure valve, and fuel tank is got back in the release of system oil pressure passing ratio pressure valve.
When signal comparator detects that servo-driver output current is not more than fuel injection pressure signal, described servo-driver is pressed velocity mode and is run, and servo-driver is in velocity mode when running, and the described oil pump speed of service is per minutely be greater than 200 turns.
