Abstract

The utility model discloses an empty pumping controller, which comprises a casing, the casing is internally equipped with a single chip, the single chip is connected with a power sensor which is mounted on a motor of a pumping unit via an A/D converter module, and a data output end of the single chip is respectively connected with a warning device and a motor driving module. The empty pumping controller directly collects operation data of the motor of the pumping unit through the power sensor, employs current curve to realize intermittent pumping judgment and control, and changes the current situation that the energy-saving and intelligent automatic control of the existing pumping unit employs a load sensor to control main parameters. The empty pumping controller is high in reliability and stability, low in cost and convenient in mounting, and therefore, the empty pumping controller is easy to be accepted by users, and has wide application prospect and market.

Description

Sky is taken out controller

Technical field

The utility model sky is taken out controller

Background technique

The production in the most oil fields of China at present enters the middle and later periods, obviously descends with landing surface throughput, and the phenomenon of well deliverability deficiency is very general.Because produce and take out imbalance, oil well pump is in the inefficient operation state for a long time, energy dissipation is serious, and the invalid wearing and tearing aggravation of equipment causes economic benefit to descend.From improving pump efficiency and energy-conservation angle, the easiest method is to adopt the batch operation mode, i.e. termination of pumping when the pumping well annulus liquid level is reduced to minimum permission position is treated to start shooting again after annulus liquid level gos up again.

The model utility content

The purpose of this utility model is to provide a kind of sky to take out controller, and it is simple in structure, can carry out sky to pumping unit effectively and take out control, thereby reduce waste of energy and mechanical wear, reduces production costs.

The purpose of this utility model is achieved in that a kind of sky takes out controller, the housing of single-chip microcomputer is housed in comprising, single-chip microcomputer links to each other by the power sensor that A/D modular converter and is installed on the pumping-unit motor, and the data output end of single-chip microcomputer is connecting warning facility and motor drive module respectively.

The utility model is directly gathered the operational data of pumping-unit motor by power sensor, utilize to take out between the current curve realization and judge and control, changed oil pump energy-saving, intelligent automation control in the past and adopted the present situation of load transducer as the control major parameter, the electrical quantity sensor is compared with load transducer, in reliability, incomparable advantage is arranged on the stability, because cost is low, convenient for installation and maintenance, hold susceptible to user acceptance, therefore the power-type sky is taken out controller and is had broad application prospects extensive market in the oil field.I﹠M of the present utility model is convenient.Need to gather the way of two parameters of power and walking beam position simultaneously different with taking out controller between early stage power method, this product is because of having adopted the intelligent analysis technology of microprocessor, only need analyze and can obtain the feed flow status information the current of electric parameter of pumping unit, so just overcome because of need be on walking beam mounting point sensor and lay the I﹠M problem that the connection lead causes.The installation of this product is very simple, and entire controller (comprising sensor) all is loaded in the electric control box, can come into operation through simple wiring.The utility model is exclusively used in the automatic intermittence control of beam pumping unit under the not enough operating mode of feed flow.Can solve present oil field: take out the tangible well of phenomenon between existence such as limit prospect pit, stripper well, enhancing efficiency by relying on tapping internal latent power well, reach energy-saving and cost-reducing purpose.

Embodiment

A kind of sky is taken out controller, as shown in Figure 1, the housing of single-chip microcomputer is housed in comprising, single-chip microcomputer links to each other by the power sensor that A/D modular converter and is installed on the pumping-unit motor, and the data output end of single-chip microcomputer is connecting warning facility and motor drive module respectively.Single-chip microcomputer becomes the power of motor signal conversion of pumping unit can supply the numerical information of computer identification, and this product adopts 12 high-precision A/D conversion chips, and power resolution can reach 0.03A/Bit, and speed can reach 100Hz.Single-chip microcomputer is the intelligent kernel of this product, should select the high-performance single-chip microcomputer for use, and its built-in big capacity electrically-erasable program storage has significantly reduced the quantity of peripheral hardware chip, and the reliability of system is strengthened greatly.Display/keyboard is human computer interaction's interface, adopts digital demonstration of 4 high-brightness LEDs and hermetically sealed film key.Storage is used for preserving the parameter of setting, guarantees after the power down that parameter can not disappear.

As shown in Figure 2, the light beam adjuster 1 that links to each other with single-chip microcomputer is being set also on housing 2, in order to show the liquid level height.3 is the LED display modular.

As shown in Figure 3,4 is power sensor among the figure, and 5 is the utility model controller.Use general operation process of the present utility model as follows: 1, control automatically: after throw over switch being pushed " automatically " gear, controller 5 powers on, pumping unit starting simultaneously; If judge to reach evacuated (real-time empty is taken out the critical sky that coefficient equals to set and taken out coefficient), pumping unit is with autostop.When remaining last 40 seconds, alarm is rung and is finished until countdown, and pumping unit will start automatically, and so far once intermittence, control procedure was finished.2, manually control: throw over switch is allocated to can be by manually controlling the starting of pumping unit by " starting button " or " stop button " or stopping behind " manually " gear.It is irrelevant whether this control function and controller 5 are connected in the electric control box, even thereby controller 5 break down, can not influence the manual control operation of pumping unit yet.3, disconnect control: throw over switch is allocated to whole controls that " disconnection " gear can cut off pumping unit, makes it to be in outage state.At the pumping unit operation process, throw over switch switched to " disconnection " or switched to " disconnection " by " manually " by " automatically " all make pumping unit out of service pressure.

Claims

1, a kind of sky is taken out controller, the housing of single-chip microcomputer is housed in comprising, it is characterized in that: single-chip microcomputer links to each other by the power sensor that A/D modular converter and is installed on the pumping-unit motor, and the data output end of single-chip microcomputer is connecting warning facility and motor drive module respectively.
