Abstract
The utility model discloses a ball mill DCS stops control circuit of high -pressure pump, including two parallel circuit, still include DCS and auxiliary relay KA25, independent and the auxiliary relay KA25 series connection of DCS, this current circuit and two parallel circuit parallel connection, auxiliary relay KA25 includes 2 contact signal, wherein first contact signal and relay contact signal KA21 parallel connection, a second contact signal and relay contact signal KA22 parallel connection. The utility model discloses DCS comes out alone with the ball mill, changes original DCS department into auxiliary relay's contact signal, can realize same control effect, only needs to give one master -control room stop the high -pressure pump signal, make stop signal simplify difficult produce chaotic.
Description
Technical field
This utility model relates to a kind of control circuit, particularly relates to a kind of ball mill DCS and stops the control circuit of high-pressure pump, belongs to technical field of electric device control.
Background technology
DCS system is as constantly rising and the day by day complicated complex control system arisen at the historic moment of process control requirements of the modern large scale industry production automation, it is computer technology, system control technique, the product that network communications technology and multimedia technology combine, it is possible to provide the man machine interface of window close friend and powerful communication function.It is complete process control, the sophisticated equipment of process management.In the running of ball mill, DCS plays important remotely controlling and supervisory function bit, the DCS stopping high-pressure pump operation of ball mill control system at present is completed (as shown in Figure 1) by two DCS signals, has two to stop high-pressure pump signal to the signal of master control room, easily causes signal chaotic.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, it is provided that a kind of ball mill DCS stops the control circuit of high-pressure pump.
For solving this technical problem, this utility model provides a kind of ball mill DCS and stops the control circuit of high-pressure pump, including two shunt circuits, also includes DCS and auxiliary reclay KA25, described DCS is individually connected in series with auxiliary reclay KA25, and this series circuit and two shunt circuits are connected in parallel；Described auxiliary reclay KA25 includes 2 contact signals, and wherein first contact signal is connected in parallel with relay contact signal KA21, and second contact signal is connected in parallel with relay contact signal KA22.
This control circuit provides a stopping high-pressure pump signal to master control room.
Beneficial effect: this utility model is by ball mill DCS the most out, the contact signal of auxiliary reclay will be changed at original DCS into, same control effect can be realized, the most only need one to stop high-pressure pump signal to the signal of master control room, make stopping signal simplifying, be not likely to produce confusion.
Accompanying drawing explanation
Fig. 1 is the control circuit figure that traditional ball mill DCS stops high-pressure pump；
Fig. 2 is circuit diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is specifically described by embodiment.
Fig. 2 show circuit diagram of the present utility model.
This utility model includes two shunt circuits, also includes DCS and auxiliary reclay KA25, and described DCS is individually connected in series with auxiliary reclay KA25, and this series circuit and two shunt circuits are connected in parallel.
Described auxiliary reclay KA25 includes 2 contact signals, and wherein first contact signal is connected in parallel with relay contact signal KA21, and second contact signal is connected in parallel with relay contact signal KA22.
Being combined Fig. 1, auxiliary reclay KA25 of the present utility model from Fig. 2 and include 2 contact signals, wherein the DCS1 in first contact signal existing control circuit of replacement is connected in parallel with relay contact signal KA21；DCS2 in second contact signal existing control circuit of replacement is connected in parallel with relay contact signal KA22.
Control circuit of the present utility model provides only a stopping high-pressure pump signal to master control room.
After described optimization circuit is supplied to master control room stopping high-pressure pump signal, master control room performs to stop high-pressure pump operation, and signal is single to be clearly not likely to produce confusion and is capable of same control effect.
This utility model by ball mill DCS the most out, will change the contact signal of auxiliary reclay into, can realize same control effect, the most only need one to stop high-pressure pump signal to the signal of master control room, make stopping signal simplifying, be not likely to produce confusion at original DCS.
This utility model the embodiment above, is merely illustrative, and is not only, and all changes in the range of this utility model or in the range of equivalent this utility model are all surrounded by this utility model.
