Abstract
The utility model discloses a novel control cabinet for vibrating screens. The novel control cabinet comprises a cabinet body and an internal circuit. The internal circuit comprises a detection unit used for directly detecting the running state of a motor power supply cable, a controller used for judging whether the running state of the motor power supply cable is normal and controlling a motor driver according to a judgment result, and an alarm used for sounding an alarm for an abnormal working condition of a motor power supply, wherein the output of the detection unit is connected with the controller, the controller is respectively connected with the alarm and the motor driver, and the motor driver is connected with a motor. The novel control cabinet adopts a commonly-used current phase-lacking detection device and is simple in circuit structure and low in cost. When any motor power supply is abnormal, the controller immediately issues a 'shutdown' command and automatically controls normal work of a vibrating screen. The problem that severe vibration causes power supply cable breakage and motor phase-lacking running damage faults to cause malfunction of a vibrating screen can be effectively solved.
Description
Technical field
The utility model relates to a kind of control cubicle, particularly a kind of novel used by oscillating screen control cubicle.
Background technology
Development along with petroleum exploration and development work, drilling depth constantly increases, drilling strata is day by day complicated, particularly development and the application of some New well drilling technology both at home and abroad in recent years, as deep-well, Ultradeep Drilling Technology, horizontal well drilling technology and under-balanced drilling technology etc., drilling fluid solid control is had higher requirement, and drilling fluid and solid control technology are the keys that guarantees that normal drilling technology is implemented.
Vibrating screen is as a kind of Solids control for drilling fluids equipment; drilling fluid density can be effectively controlled in reasonable design and use; remove the harmful solid phase in drilling fluid; to improving rate of penetration, improve follow-up equipment as the useful life of drilling pump, drilling tool, downhole instrument etc., save the aspects such as mud drug dosage, protection oil-gas Layer and be significant.In order to overcome high vibration, cause feed cable fracture to cause the phenomenon of motor phase failure operation damage, some producers carry out power phase shortage detection by multifunctional three phase power source control relay is installed.What detect due to this kind of method is whether phase shortage of front end, and the motor being equipped with on vibrating screen is two or three, only has the motor same phase time of phase shortage simultaneously, and inlet wire front end just can detect phase shortage.And this kind of phenomenon of the failure at the scene in operating open-phase fault phenomenon proportion minimum, thereby this kind of scheme possesses significant limitation.In order to solve thoroughly high vibration, cause feed cable fracture to cause the phenomenon of motor phase failure operation damage, need a kind of new checkout gear and method.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of conventional electric current phase shortage detecting element that adopts is provided, and circuit structure is simple, with low cost; Can effectively solve because high vibration causes feed cable fracture, motor phase failure moves a kind of novel used by oscillating screen control cubicle of damaging fault and causing the accidents such as vibrating screen fault.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel used by oscillating screen control cubicle, it comprises cabinet and internal circuit, described internal circuit comprises the detecting unit for the running status of direct-detection motor power cable, for judging motor power cable running status whether normal and the controller of motor driver being controlled according to judged result and the alarm that motor power non-normal working situation is given the alarm, the output of detecting unit is connected with controller, the output of controller is connected with motor driver with alarm respectively, motor driver is connected with motor.
Described cabinet is flame proof cabinet.
Described detecting unit is electric current phase shortage detecting element.
The beneficial effects of the utility model are:
1, adopt conventional electric current phase shortage detecting element, circuit structure is simple, with low cost;
2, when any motor power is undesired, controller is made the order of " shutdown " immediately, to controlling the normal operation of vibrating screen, automatically control, can effectively solve because high vibration causes feed cable fracture, motor phase failure operation is damaged fault and is caused the accidents such as vibrating screen fault;
3, have good explosion-proof effect, all devices is installed in anti-explosion cabinet, without other auxiliary equipment, installs and convenient transportation.
Accompanying drawing explanation
Fig. 1 is system configuration schematic diagram of the present utility model;
Fig. 2 is workflow diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model, but the content that the utility model is protected is not limited to the following stated.
As shown in Figure 1, a kind of novel used by oscillating screen control cubicle, it comprises cabinet and internal circuit, described internal circuit comprises the detecting unit for the running status of direct-detection motor power cable, for judging motor power cable running status whether normal and the controller of motor driver being controlled according to judged result and the alarm that motor power non-normal working situation is given the alarm, the output of detecting unit is connected with controller, the output of controller is connected with motor driver with alarm respectively, and motor driver is connected with motor.
Described cabinet is flame proof cabinet.
Described detecting unit is electric current phase shortage detecting element.
As shown in Figure 2, operation principle of the present utility model is:
S1: Vibration on Start-up screen system;
S2: whether the electric current that detecting unit detects motor power is normal, detects if electric current normally keeps equipment normally to move and continue, and carries out next step detection if undesired;
S3: whether the abnormality that judges motor power electric current is phase shortage, if not phase shortage keeps equipment normally to move and returns to step S2 and proceed to detect, if phase shortage, controller sends halt command, controls motor driver and stops drive motors, and control alarm and give the alarm;
S4: stop shaker systems and overhaul.
