Description
Technical field
The utility model relates to a kind of crude oil oil pumper intelligent type energy saving control device, particularly a kind of beam pumping unit intelligent type energy saving control device.
Background technology
Oil pumper is the requisite a kind of machinery equipment of crude oil extraction in petroleum industry, its version is varied, wherein beam pumping unit occupies critical role and is commonly called as " machine of kowtowing ", its operation principle is that motor power passes to crank after speed changer slows down, crank passes through connecting rod again, beam, horse head drives sucker rod and moves up and down, realization becomes rotation into the vertical reciprocating type motion, in this process, because the up-down stroke demand motive force is different, so solve the dynamic equilibrium of two strokes, energy savings reduces the interference to electrical network, it is the main target of this beam type fuel charger design, equilibrate to the counterweigh of balance weight by vapour-pressure type, though larger progress has been arranged, the energy in oil recovery process subtracts the deficiency of still doing aspect the consumption, " gas lock ", " liquid is stifled " phenomenon happens occasionally, cause the loss of parts, along with industrial automation, the propelling of intelligent control process, this fuel charger still have huge technical development space.
The utility model content
In order to make fuel charger more energy-conservation, more intelligent, the purpose of this utility model provides a kind of oil pumper intelligent type energy saving control device, makes oil pump running control freely, saves energy.
The utility model is by the following technical solutions: a kind of oil pumper intelligent type energy saving control device is characterized in that comprising frequency conversion drive module, microcomputer controller, crank position detector and torque measurement parts; The crank position detector is made of Hall element and circular inductive disks, the inductive disks curved edge is evenly distributed with permanent magnet, inductive disks is connected with the crank of reduction box of oil pumping unit driving shaft is coaxial, the fixing Hall element in the position of corresponding permanent magnet running orbit on oil pumper, Hall element is connected with microcomputer controller by cable, the torque measurement parts are connected with microcomputer controller, and microcomputer controller is connected with the frequency conversion drive module.
Described oil pumper intelligent type energy saving control device, it is characterized in that on this circle inductive disks, being provided with a permanent magnet two or projection outside the permanent magnet annular track, corresponding permanent magnet two or projection are provided with Hall element or travel switch at oil pumper, and the signal that produces during operation is used for microcomputer controller location crank original position.
Described oil pumper intelligent type energy saving control device is characterized in that these torque measurement parts are made of current sampling circuit, reference circuit and comparison analog to digital conversion circuit, are connected with the frequency conversion drive module through microcomputer controller.
Described oil pumper intelligent type energy saving control device is characterized in that the inductive disks periphery is zigzag, and corresponding zigzag projection is electromagnetic inductor.
The utility model can be automatically according to torque, degree of filling automatic control motor rotating speed when up-down stroke; regulate realization by the intelligence of jig frequency and eliminate " gas lock " and " liquid is stifled " phenomenon; keep the crude oil liquid level constant; reduce the rate of wear of parts; it is more convenient, more reliable that equipment operating is used, and reduces downtime and maintaining expense.
Description of drawings:
Fig. 1, the overall structure schematic diagram of the utility model embodiment.
Fig. 2, the electric control structure schematic diagram of the utility model embodiment.
Fig. 3, location of the present utility model inductive disks and transducer.
Accompanying drawing indicates title: 1 Hall element; 2 inductive disks; 3 permanent magnets; 4 permanent magnets two; 5 crank drive shaft; 6 electrical control casings.
Embodiment:
The utility model embodiment, such as Fig. 1, shown in Figure 2, for being provided with coaxial inductive dish 2 in the beam type fuel charger crank drive shaft 5 of commonly seeing, this inductive disks 2 is circular, inductive disks 2 curved edges are evenly distributed with permanent magnet 3, corresponding permanent magnet 3 is fixed with a Hall element 1 in frame, along with crank drive shaft 5 is rotated inductive disks 2 rotations, permanent magnet 3 moves, Hall element 1 detects magnetic signal and converts the signal of telecommunication to, the signal of telecommunication is passed to microcomputer controller in the electric control box 6, sample circuit is taken a sample from the frequency conversion drive module, sampled signal output one digital signal after analog to digital conversion circuit and reference signal contrast computing arrives microcomputer controller, microcomputer controller is with two signal-data processing computings, the frequency conversion drive module is exported a speed control signal, because the most direct response data of operating state when torque is the oil pumper up-down stroke, so what the speed controling signal that draws according to real-time torque and the computing of sucker rod position data can be real-time adjusts jig frequency, realized the control to oil pumper up-down stroke speed, " gas lock " when being discontented with from solving to the full extent degree of filling, " liquid is stifled " phenomenon, keep the page constant, improve degree of filling, in energy efficient, reduce greatly the loss to oil well pump and sucker rod, also improved the intellectuality control of oil pumper.
Location for the crank starting point, permanent magnet 3 annular traces were outer on the inductive disks 2 when the utility model was implemented can be provided with a permanent magnet 24 or projection, corresponding permanent magnet 24 or projection are provided with Hall element 1 or travel switch at oil pumper, the signal that produces during operation is used for microcomputer controller location crank original position, be the sucker rod position, the process of monitoring stroke.
Only be an embodiment of the present utility model in sum, all equivalences of doing according to the application are modified and all are considered as the utility model technology category.
