Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
The utility model provides an embodiment of a system for monitoring abnormal oil pressure of a press bar, in particular to a system for monitoring abnormal oil pressure of a press bar, as shown in fig. 1, which comprises the following components: an electric contact pressure gauge 1, an alarm 2, a controller 3 (which can be an original machine controller of a rod pressing machine or a PLC programmable controller), an oil pump motor 100 and a rod pressing motor 200;
the oil pump motor 100 is used for regulating and controlling oil pressure;
The rod pressing motor 200 is used for driving rod pressing start and stop operation of the rod pressing machine;
The controller 3 is respectively connected with the electric contact pressure gauge 1, the alarm 2, the oil pump motor 100 and the rod pressing motor 200 in a signal manner.
The electric contact pressure gauge is an instrument which is additionally provided with an electric device on the basis of the traditional pressure gauge and can output a switching value signal when indicating working pressure when equipment reaches set pressure so as to realize detection of oil pressure. Specifically, the electric contact pressure gauge 1 may include an indicating device, a contact device, an adjusting device, a casing and a junction box, more specifically, the indicating device of the electric contact pressure gauge 1 is a pointer, the adjusting device is at least two setting pins, contacts can be respectively installed on the pointer and the setting pins, and when in use, the upper limit setting pin and the lower limit setting pin are adjusted to required pressure points. When the pressure changes, the pointer reaches the upper limit or the lower limit setting needle, the contact point on the pointer is contacted with the contact point on the upper limit or the lower limit setting needle, and a switching value signal is sent to the controller through an electric circuit to trigger the alarm to work.
The alarm at least comprises any one of the following: visual alarm, audible alarm and audible and visual alarm.
Taking the audible and visual alarm as an example, in some preferred embodiments of the present utility model, the method specifically includes: in actual operation, the red light can be used for representing fault warning, for example, the oil pump pressure of the bar pressing machine is lower than the minimum value set by the electric contact pressure gauge; the green light represents a normal running state, for example, the normal oil pressure of the bar pressing machine is indicated; the yellow lamp state can be used as a fault early warning to indicate that the oil pressure of an oil pump motor of the bar pressing machine is increased, and the rotating speed of the oil pump motor needs to be reduced. And, when red light or yellow light output, the buzzer can cooperate to send out different sound effects (for example, according to different frequencies and preset sound templates).
In combination with the foregoing description, the usage mode of the controller may refer to that when the pressure of the electric contact pressure gauge is greater than a preset maximum value, the yellow lamp and the buzzer are triggered, and the oil pump motor may be driven to operate and control the rotation speed to decrease; for another example, the controller may trigger the red light and the buzzer when the pressure of the electric contact pressure gauge is less than a preset minimum value, and may control the rod pressing to stop electrically and resume to start subsequently.
The audible and visual alarm can be additionally arranged above the rod beating machine electric control cabinet, according to the example, the audible and visual alarm can be provided with three colors of lamps, a green lamp indicates that the oil pressure of the oil pump motor is in a range of a set value of the electric contact pressure gauge, a red lamp indicates that the oil pressure of the oil pump motor is lower than a set minimum value of the electric contact pressure gauge, and a yellow lamp indicates that the oil pressure of the oil pump motor is higher than a set maximum value of the electric contact pressure gauge. When the oil pressure detection value of the rod beating machine is within a normal setting range, the alarm displays a green light and no buzzer is output; when the oil pressure detection value of the rod making machine is smaller than the set minimum value, the condition that the oil way pipeline is abnormal is indicated, the crankshaft of the rod making machine is short in oil loss for a long time, the temperature of the crankshaft is increased due to the increase of friction force, the service life of the crankshaft is influenced, and the alarm is in an alarm state: displaying a red light and emitting a beeping sound to prompt an operator that the oil pressure is low and the oil pressure is required to be processed in time, namely, the normal starting can be performed only by manually overhauling to solve the fault, and correspondingly, the shutdown operation of the rod pressing motor can be triggered to avoid serious damage; when the oil pressure detection value of the rod beating machine is higher than the set maximum value, the oil pump motor is required to run at a reduced speed, the pressure output is reduced, the pressure of an oil way pipeline is reduced, the oil pipe is prevented from bursting, and the alarm is in an early warning state at the moment: the yellow lamp is displayed and beeps to prompt operators that the oil pressure is high, the rotation speed of the oil pump motor needs to be reduced, the oil pump pressure is inevitably and automatically reduced after the rotation speed is reduced, and the audible and visual alarm warning can be automatically reset. This is, of course, an illustrative example of an application and is not an emphasis on the present utility model.
Finally, it may be further added that the system may further include: and the display screen 4 is in signal connection with the controller 3 and is used for displaying the state of an oil pump motor of the bar pressing machine.
In summary, the main design concept of the utility model is that through the pressure detection of the electric contact pressure gauge and the fault warning of the alarm, the working personnel can find the fault in time, find the specific position of the fault in time and process the fault, and the damage of the crankshaft of the bar pressing machine caused by the abnormal pressure of the oil pump is prevented. Specifically, the system mainly comprises an electric contact pressure gauge, an alarm, a controller, an oil pump motor and a rod pressing motor, wherein the controller is respectively in signal connection with the electric contact pressure gauge, the controller, the oil pump motor and the rod pressing motor. The utility model can detect the oil pressure in real time and output pressure alarm information, thereby prompting the fault information of operators in time, achieving the purposes of reducing the equipment fault shutdown rate and the fault maintenance cost, and reliably and pointedly eliminating the hidden trouble of equipment.
