By adopting the device provided by the utility model, the work efficiency is greatly improved, the safety of personnel is protected, and the safety and the reliability of equipment work are guaranteed.
Description
Technical field
The utility model relates to a kind of oil field distribution arrangements for speed regulation, is applied to oil recovery field, oil field.
Background technology
Oil field distribution arrangements for speed regulation are widely used in oil extraction process, and the stability of device, reliability all produce significant effects to the exploitation in oil field and staff's safety.Currently used distribution arrangements for speed regulation comprise sensor, frequency converter, this device transports sensor and directly is filled on the frequency converter at the 4-20mA direct current signal, but the control to flow, liquid level and the pressure of oil on the oil pump can not calculate and handle accurately, this control mode is a kind of control of extensive style, control accuracy is very low, anti-interference is poor, and frequency converter itself can produce powerful higher hamonic wave, causes equipment malfunction to take place frequently.When equipment manual forwards automatic transmission to, be easy to produce disturbance, therefore can the dragging motor rotating speed from high to low, circulation vibration from low to high reaches one minute oscillation period again, this situation is very easily damaged oil pump.This device can not show the various data when recovering the oil in real time simultaneously, can not report to the police automatically and trip protection to various accident conditions.
Summary of the invention
The purpose of this utility model is to avoid above prior art to propose a kind of oil field power distribution equipment in deficiency.The utility model is achieved through the following technical solutions:
A kind of oil field distribution arrangements for speed regulation, this device comprises oil field pump, frequency converter, sensor, this device also comprises programmable logic controller (PLC) PLC, touch-screen, one input end of described sensor links to each other with the endpiece of oil field pump, one output terminal of this sensor feeds back to an input end of oil field pump respectively through described programmable logic controller (PLC) PLC, frequency converter, described programmable logic controller (PLC) PLC also is connected with touch-screen.
Further, described sensor is connected by the profibus bus with described programmable logic controller (PLC) PLC.
Further, the described profibus bus gauze screen that is outside equipped with a ground connection.
Further, the signal of the output terminal output that links to each other with programmable logic controller (PLC) PLC of described sensor is the 4-20mA direct current signal
Advantage of the present utility model is:
1. Zhuan Zhi antijamming capability is strong, reliability, stability height;
2. this device can show service data in real time, and the memory function of accident and data is arranged;
3. this device has automatic protection and tripping alarm function.
Description of drawings
Fig. 1: structure principle chart of the present utility model;
Fig. 2: electrical schematic diagram of the present utility model.
Embodiment
Be illustrated in figure 1 as structure principle chart of the present utility model, Fig. 2 is an electrical schematic diagram of the present utility model.The utility model comprises oil field pump 1, sensor 2, frequency converter (VF) 3, programmable logic controller (PLC) (PLC) 4, touch-screen 5.One input end of described sensor 2 links to each other with the endpiece of oil field pump 1, one output terminal of this sensor 2 feeds back to an input end of oil field pump 1 respectively through described programmable logic controller (PLC) 4, frequency converter 3, described programmable logic controller (PLC) 4 also is connected with touch-screen 5.Described sensor 2 is connected by the profibus bus with described programmable logic controller (PLC) 4, and this profibus bus is outside equipped with the gauze screen 6 of a ground connection, and the application of this profibus bus and gauze screen greatly reduces undesired signals such as harmonic wave.
The endpiece of oil field pump 1 flow, liquid level or the pressure of gathering oil real-time pass to sensor 2, sensor 2 is converted to corresponding 4-20mA direct current signal with these data messages, pass to programmable logic controller (PLC) (PLC) 4 by the profibus bus, the CPU of this PLC carries out PID computing adjusting after reading signal, and the corresponding O-10V d. c. voltage signal of output is given frequency converter 3, the corresponding 0-50HZ frequency signal of output is given the motor of oil field pump after frequency converter 3 received signals, and rotating speed of motor is controlled and regulated.Described oil field pump 1, sensor 2, frequency converter 3, programmable logic controller (PLC) 4 form a closed loop feedback system, make oil production equipment to carry out stable running according to flow, liquid level or the force value set all the time.
The setting of flow, liquid level or force value is to be controlled by the touch-screen 5 that links to each other with programmable logic controller (PLC) 4, and touch-screen can be the display of PC.Simultaneously the utility model also has protection and tripping alarm function automatically, and when flow, liquid level or the force value of equipment collection surpasses when being set in advance in warning value, the alarm unit on the touch-screen can send alerting signal and take appropriate measures with the prompting staff.
Application of the present utility model has greatly improved work efficiency, has ensured security, the reliability of personnel and equipment work.
