Embodiment Construction

[0029] based on the following Figure 1 to Figure 5 , specifically explain the preferred embodiment of the present invention.

[0030] In the ABS composite material production device, the instrument cables in the two redundant vacuum systems are first connected to the field junction box, then introduced into the instrument cabinet room through the instrument bridge, then connected to the cabinet terminal block, and finally connected to the PLC card of the control system .

[0031] Such as figure 1 As shown, the present invention provides a method for troubleshooting an instrumentation of an ABS composite material production device, comprising the following steps:

[0032] Step S0, the control system judges whether the ABS composite material production device fails, and if so, proceed to step S1;

[0033] Step S1, check whether the field junction box connected to the meter is faulty, if so, go to step S2, if not, go to step S3;

[0034] Step S2, performing fault repair on t...

Abstract

An instrument fault elimination method used for an ABS composite material production device comprises the steps of checking whether an on-site junction box in which an instrument accesses goes wrong,if yes, repairing the fault of the on-site junction box, if not, checking whether a cabinet terminal line in which the instrument accesses goes wrong, if yes, repairing the fault of the cabinet terminal line, if not, checking whether a PLC fastening member in which the instrument accesses goes wrong, if yes, replacing the damaged PLC fastening member, if not, orderly checking whether all instruments go wrong, and replacing the faulted instruments. The instrument fault elimination method of the present invention can effectively eliminate the instrument faults of the ABS composite material production device, guarantees that a vacuum system is located in a redundant state, and guarantees the safe and stable production of the ABS composite material production device.

Description

technical field [0001] The invention relates to the field of instrument power supply, in particular to an instrument troubleshooting method for an ABS composite material production device. Background technique [0002] When the ABS composite material production device is in production, the raw material is first collected from the raw material tank area, and the raw material enters the sol tank and dissolves together with the rubber block after the rubber cutting system, and then the dissolved material is sent to the reactor, and the additive is added for reaction. The reacted product enters the devolatilizer for devolatilization, and the vacuum system extracts the incompletely volatilized material from the devolatilizer for re-reaction, while the fully volatilized material is drawn and diced, and then enters the air delivery system for finished product packaging. If there is no purification by the vacuum system, there will be impurities in the material drawn from the wire dr...
