Description
Technical field
The utility model relates to small pump control technology field, particularly relates to a kind of moisturizing frequency conversion tank.
Background technology
In recent years, along with the fast development of society, robotization and the intelligence degree of water system are constantly improved, and small pump is as the important step of in water system, and the reliability of its control procedure and security directly have influence on reliability and the security of water system; At present, traditional moisturizing frequency conversion tank is mainly divided into Non-follow control and Based Intelligent Control two kinds, but found by practice, all there is different defects in above-mentioned two kinds of moisturizing frequency conversion tank, such as: the moisturizing frequency conversion tank of Non-follow control mainly relies on Non-follow control and the operation of slip-stick artist, therefore often there is maloperation or the generation of other accident; The moisturizing frequency conversion tank of Based Intelligent Control mainly relies on the program of establishing in PLC to complete control to moisturizing frequency converter, therefore whole control procedure does not need slip-stick artist to intervene, but at some in particular cases, slip-stick artist needs the control procedure changing moisturizing frequency converter, then need the control device disassembling intelligent moisturizing frequency converter, be then adapted as manual just can realizing; Therefore, a kind of to integrate manually and the moisturizing frequency conversion tank of intelligentized control method seems particularly important is designed and developed.
Utility model content
The technical problems to be solved in the utility model is: provide the moisturizing frequency conversion tank that a kind of flexible operation, safety coefficient are high.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A kind of moisturizing frequency conversion tank, comprises cabinet, is provided with moisturizing frequency conversion control circuit in described cabinet; It is characterized in that: described moisturizing frequency conversion control circuit comprises soft initiator, the model of described soft initiator is XPR1-CN, and the second terminal of described soft initiator is connected with A.C. contactor; 7th terminal of described soft initiator is connected with the 8th terminal by auxiliary reclay, 8th terminal of described soft initiator and the electrical connection of the 9th terminal, 7th terminal of described soft initiator and the electrical connection of the tenth terminal, the 3rd terminal and the 4th connecting terminals of described soft initiator are connected to A.C. contactor and signal lamp; Be Non-follow control input terminal after 3rd terminal of described soft initiator, Five-terminals, the first terminal short circuit; Described second terminal is successively by being electrically connected by data line with PLC after A.C. contactor, auxiliary reclay.
Also comprise the reometer of the working current for detecting described moisturizing frequency conversion control circuit, for detecting the voltage table of the operating voltage of described moisturizing frequency conversion control circuit; Described reometer is series at moisturizing frequency conversion control circuit between power supply; Described voltage table is in parallel with moisturizing frequency conversion control circuit.
The advantage that the utility model has and good effect are: by adopting technique scheme, Non-follow control and PLC control to be integrated in one by the utility model, therefore moisturizing frequency conversion tank, in the process used, both can realize Non-follow control, also can realize Automated condtrol; Meanwhile, because the utility model also adds reometer and voltage table, therefore can detect the working current of moisturizing frequency conversion control circuit and operating voltage, prevent trouble before it happens.

Fig. 2 is current measurement circuit circuit diagram of the present utility model;
Fig. 3 is voltage measurement circuit circuit diagram of the present utility model.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of moisturizing frequency conversion tank, comprises cabinet, is provided with moisturizing frequency conversion control circuit in described cabinet; Described moisturizing frequency conversion control circuit comprises soft initiator, and the model of described soft initiator is XPR1-CN, and the second terminal of described soft initiator is connected with A.C. contactor KM; 7th terminal of described soft initiator is connected with the 8th terminal by auxiliary reclay KA, 8th terminal of described soft initiator and the electrical connection of the 9th terminal, 7th terminal of described soft initiator and the electrical connection of the tenth terminal, the 3rd terminal and the 4th connecting terminals of described soft initiator are connected to A.C. contactor KM and signal lamp; Be Non-follow control input terminal after 3rd terminal of described soft initiator, Five-terminals, the first terminal short circuit; Described second terminal is successively by being electrically connected by data line with PLC after A.C. contactor KM, auxiliary reclay KA.For the ease of the working state administration to PLC, be connected with multiple control knob at PLC and auxiliary reclay KA, the button SS such as in diagram is scram button; As shown in Figure 1, for the ease of the display to duty, in moisturizing frequency conversion control circuit, be also provided with multiple working station indicator; In order to improve the security performance of equipment, the connection wire between cabinet and power supply is in series with fuse FU; The principle of work of this specific embodiment is, when needs carry out Non-follow control, slip-stick artist manually control input terminal can input a low and high level, such as high level is for opening soft initiator, low level for closing soft initiator, when needs carry out Automated condtrol, slip-stick artist can open PLC, and now PLC controls soft initiator process, when an emergency happens, PLC can be closed by scram button SS.
Because moisturizing frequency conversion tank belongs to powerful equipment, therefore often can transship, for this reason, in order to prevent trouble before it happens, on the basis of above-mentioned specific embodiment, moisturizing frequency conversion tank also comprise the working current for detecting described moisturizing frequency conversion control circuit reometer, for detecting the voltage table of the operating voltage of described moisturizing frequency conversion control circuit; Described reometer is series at moisturizing frequency conversion control circuit between power supply; Described voltage table is in parallel with moisturizing frequency conversion control circuit.Such slip-stick artist namely by reometer and voltage table the duty to moisturizing frequency conversion tank monitor in real time, improve its security performance.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
