Abstract
The utility model relates to an overpressure protective device of a diamond press. The overpressure protective device of the diamond press comprises a pressure transducer, a relay, a programmable logic controller (PLC) and an automatic air switch, wherein one side of the PLC is electrically connected with a pressure transducer, the other end of the PLC is connected with the automatic air switch, and the relay is arranged between the pressure transducer and the PLC. The overpressure protective device of the diamond is capable of cutting off the power promptly to stop the work of the hydraulic pump when the device pressure is too high, thereby avoiding equipment damage, and reducing running cost of the device.
Description
Technical field
The utility model relates to a kind of building block of diamond press, is specifically related to a kind of over-pressure safety device of diamond press, belongs to the diamond press technical field.
Background technology
When catastrophic discontinuityfailure appearred in diamond press, the AC relay of control super-pressure pump work will be burnt out.Though the control circuit of PLC meeting automatic disconnection; Yet the AC relay of control super-pressure pump can be inhaled to stubbornly refuse in time to break off and work on because of electric current; The hypertonia that will cause diamond press like this; The hydraulic press main frame can't stand that because of holding excess pressure bursts apart, and causes the personal safety accident to increase the apparatus maintenance cost simultaneously.
Therefore, for solving the problems of the technologies described above, necessary a kind of over-pressure safety device with structure improved diamond press is provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem, it is a kind of simple in structure that the purpose of the utility model is to provide, and can effectively keep away the over-pressure safety device of the diamond press of hypertonia.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of over-pressure safety device of diamond press, and it comprises pressure sensor, relay, PLC controller and automatic air-break switch; Wherein, said PLC controller one side is electrically connected with pressure sensor, and opposite side is electrically connected with automatic air-break switch; Said relay is arranged between pressure sensor and the PLC controller.
The over-pressure safety device of the diamond press of the utility model further is set to: on said pressure sensor, further be provided with a pressure display unit.
Compared with prior art; The utlity model has following beneficial effect: the over-pressure safety device of the diamond press of the utility model can in time be cut off the electricity supply when the equipment hypertonia hydraulic pump is quit work; Thereby avoided device damage, the operating cost of the equipment of reduction.
Description of drawings
Fig. 1 is the schematic diagram of over-pressure safety device of the diamond press of the utility model.
Embodiment
See also shown in the Figure of description 1, the utility model is a kind of over-pressure safety device of diamond press, and it is made up of several parts such as pressure sensor 1, relay 2, PLC controller 3 and automatic air-break switches 4.
Wherein, said PLC controller 3 one sides are electrically connected with pressure sensor 1, and opposite side is electrically connected with automatic air-break switch 4.And this PLC controller 3 also is connected with power supply.
On said automatic air-break switch 4, be connected with the hydraulic pump 9 of various models, open this automatic air-break switch 4 and can make each hydraulic pump 9 be in the stand-by operation state.
Said relay 2 is arranged between pressure sensor 1 and the PLC controller 3.
On said pressure sensor 1, further be provided with a pressure display unit 5, thereby can the pressure value in the system be shown intuitively.
The operation principle of the over-pressure safety device of the diamond press of the utility model is following: when equipment produces pressure above set point; Detect concrete force value by pressure sensor 1; Feed back to PLC controller 3 simultaneously, PLC controller 3 sends instruction and gives relay 2, makes the breaking coil of relay 2 timely breaking inners; Thereby stop the work of all big primary hydraulic pumps 9, can resume work after waiting to ascertain the reason.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
Claims (2)
1. the over-pressure safety device of a diamond press is characterized in that: comprise pressure sensor, relay, PLC controller and automatic air-break switch; Wherein, said PLC controller one side is electrically connected with pressure sensor, and opposite side is electrically connected with automatic air-break switch; Said relay is arranged between pressure sensor and the PLC controller.
2. the over-pressure safety device of diamond press as claimed in claim 1 is characterized in that: on said pressure sensor, further be provided with a pressure display unit.
