Abstract
The utility model discloses a control cabinet of a brake screw pump oil pumping unit. A shell is internally divided into a first chamber and a second chamber by a diaphragm; the first chamber is provided with an operating handle of an automatic air circuit breaker, a digital display screen of an intelligent motor protector, a start button, a stop button and an indicating lamp; the second chamber is provided with the automatic air circuit breaker, a vacuum AC contactor, the intelligent motor protector, a motor brake, a brake contactor, a load side outlet terminal and a power side inlet terminal; and the operating handle of the automatic air circuit breaker of the first chamber is connected with the automatic air circuit breaker of the second chamber. When the oil pumping unit stops pumping, the motor brake is connected to a motor stator winding through the brake contactor to generate brake torque, limit the reversing speed of the unit, slowly release the reverse torque and ensure the safety of oil pumping equipment and personal safety of operating personnel, so that the control cabinet has obvious economic and social benefits.
Description
Technical field
The utility model relates to a kind of screw pump oil pumping machine control cabinet, particularly a kind of brake type screw pump oil pumping machine control cabinet.
Background technology
There is following defective in the screw pump oil pumping machine control cabinet in production run: 1, the screw pump oil pumper is when stop pumping, can produce very big opposing torque, when particularly the holddown fault takes place in the down-hole, huge opposing torque can make the motor high speed reverse rotation, make the motor pulley fragmentation, fly out at a high speed, in the time of damage equipment, serious threat staff's personal safety, existing control cubicle does not have braking function, can't eliminate this serious hidden danger; 2, control cubicle forceful electric power road part and operation part mix, and coefficient of safety was low when the staff operated, and electric shock or electricity easily take place hinder accident; 3, existing control cubicle easily comes in contact device main contact adhesion accident in start-up course.
Summary of the invention
The purpose of this utility model is a kind of brake type screw pump oil pumping machine control cabinet of design, when the screw pump stop pumping, produce braking moment, the potential safety hazard when eliminating screw pump oil pumper stop pumping or holddown, improve device security, the personal safety during the safeguard work personnel operation.
The purpose of this utility model is achieved in that by housing; automatic air circuit breaker; intelligent motor protector; the vacuum A.C. contactor; motor brake; braking contactor is formed; it is characterized in that: enclosure interior is divided into a chamber by dividing plate; two chambers; one chamber is equipped with the operating grip of automatic air circuit breaker; the digital display screen of intelligent motor protector; start button; stop button; indicator light, two chambers are equipped with automatic air circuit breaker; the vacuum A.C. contactor; intelligent motor protector; motor brake; braking contactor; load side outlet binding post; mains side inlet wire binding post.The input of motor brake links to each other with automatic air circuit breaker, and the output of motor brake links to each other with the braking contactor input, and the braking contactor output links to each other with the load side binding post.
The beneficial effects of the utility model are: motor brake and braking contactor are installed in the control cubicle, the screw pump oil pumper is when stop pumping or holddown shutdown, produce braking moment, braking moment increases along with the rising of rotating speed, limited the speed reversal of motor effectively, eliminate the major hidden danger that the motor pulley fragmentation flies out, protected the safety of equipment and staff's personal safety; Fitting operation part in one chamber, be installed as forceful electric power element chamber in two chambers, dividing plate separates two chambers, two chambers can be separated with the external world, solved the defective that existing oil pumping machine control cabinet exists, barrier propterty is good, effectively reduce the rate of failure that sleety weather causes, long service life, operate in the chamber and finish, handling safety coefficient height is guaranteed staff's personal safety, can effectively improve the reliability and the processing safety of oil well electric power system, have remarkable economic efficiency and social benefit.
Description of drawings
Accompanying drawing 1 is the utility model one chamber schematic diagram.
Accompanying drawing 2 is the utility model two chamber schematic diagrames.
Among Fig. 1,2, the 1st, housing; The 2nd, dividing plate; The 3rd, the automatic air circuit breaker operating grip; The 4th, the digital display screen of intelligent motor protector; The 5th, start button; The 6th, stop button; The 7th, indicator light; The 8th, automatic air circuit breaker; The 9th, intelligent motor protector; The 10th, the vacuum A.C. contactor; The 11st, motor brake; The 12nd, braking contactor; The 13rd, load side outlet binding post; The 14th, mains side inlet wire binding post.
Embodiment
1,2 couples of embodiment of the present utility model describe below in conjunction with accompanying drawing.
Embodiment of the present utility model is by housing 1; dividing plate 2; automatic air circuit breaker operating grip 3; the digital display screen 4 of intelligent motor protector; start button 5; stop button 6; indicator light 7; automatic air circuit breaker 8; intelligent motor protector 9; vacuum A.C. contactor 10; motor brake 11; braking contactor 12; load side outlet binding post 13; mains side inlet wire binding post 14 is formed; housing 1 inside is divided into a chamber by dividing plate 2; two chambers; one chamber is equipped with the operating grip 3 of automatic air circuit breaker; the digital display screen 4 of intelligent motor protector; start button 5; stop button 6; indicator light 7; two chambers are equipped with automatic air circuit breaker 8; vacuum A.C. contactor 10; intelligent motor protector 9; motor brake 11; braking contactor 12; load side outlet binding post 13; mains side inlet wire binding post 14; the operating grip 3 of the automatic air circuit breaker of one chamber is connected with the automatic air circuit breaker 8 of two chambers; the input of motor brake 11 links to each other with automatic air circuit breaker 8; the output of motor brake 11 links to each other with the input of braking contactor 12, and the output of braking contactor 12 links to each other with load side binding post 13.
When stop pumping of screw pump oil pumper or holddown shutdown, braking contactor gets electric adhesive, motor brake makes motor produce braking moment, braking moment increases along with the rising of motor reverse speed, this braking moment has limited the speed reversal of motor effectively, eliminate the major hidden danger that the motor pulley fragmentation flies out, protected the safety of equipment and staff's personal safety; Housing 1 is a stainless steel, the top is a waterproof domatic structure, Qianmen and back door are housed close a chamber and two chambers respectively, two chambers are isolated operation part and strong power part separately, opening, stop well operation and reference record finishes in a chamber, handling safety coefficient height is guaranteed staff's personal safety.Vacuum A.C. contactor 10 is starting and is stopping in the process of oil pumper, the electric arc that produces is extinguished in the enclosed vacuum arc control device fast, arc extinction performance is good, long service life, can eliminate the problem of main contact adhesion, be applicable in the hazardous environment of oil wells in field to have higher explosion-proof security.
