Abstract
The utility model relates to a novel starting device for an oil pumping unit. The device adopts the technical scheme that an automatic air switch (QS), an AC contactor (KM), a thermorelay (FR), a intermediate relay (ZJ) and a motor (M) are included, wherein the motor (M) is electrically connected with a three-phase circuits (L1, L2 and L3) through the thermorelay (FR) and the AC contactor (KM); two circuits of the three-phase circuits (L1, L2 and L3) are connected with the intermediate relay (ZJ); and the rest one circuit is connected with the thermorelay (FR), the intermediate relay (ZJ), start buttons (SB1 and SB2), a timer (SJ) and the AC contactor (KM). The utility model has the benefits of realizing regular start and stop of an oil well which has the problems of low permeation liquid supplying shortage and intermittent oil leakage, and achieving the purposes of saving the electric energy, reducing the labor intensity and improving the work efficiency.
Description
One, technical field:
The utility model relates to a kind of petroleum machinery equipment, particularly a kind of new pumping unit starting drive.
Two, background technology:
At present, the oil field line that recovers the oil uses the oil pumping machine control cabinet starting drive mainly to adopt electronic products such as " comprehensive protector of motor ", and the motor used to oil pumper can only carry out the phase failure, overcurrent protection.Because oil pumping machine control cabinet uses for a long time in the open air; natural conditions are abominable; especially the moisture of sleety weather is very big to the electronic product influence; very easily cause its damage, cause " comprehensive protector of motor " misoperation or be failure to actuate, and the fault that this series products occurs is difficult for being found by the post workman; and it is bigger to repair difficulty; make motor can not get effective protection, cause motor overheating even burn, influenced the ordinary production of oil well.In addition; in line with energy-saving and cost-reducing principle; " open " system is carried out to hyposmosis feed flow deficiency, intermittently fuel-displaced oil well in the oil field, and original " comprehensive protector of motor " product of etc.ing does not possess the function that timing automatic starts, and can't satisfy the actual needs at the scene of oil recovery.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of new pumping unit starting drive is provided, and has open phase protection, and overcurrent protection and timing start function, and it is simple in structure, dependable performance, and installation and maintenance are convenient, and are energy-saving and cost-reducing.
Its technical scheme is: mainly be made up of automatic air-break switch (QS), A.C. contactor (KM), thermal relay (FR), auxiliary relay (ZJ), motor (M), described motor (M) is electrically connected with three-phase electricity (L1, L2, L3) by thermal relay (FR), A.C. contactor (KM), two-way in the described three-phase electricity (L1, L2, L3) connects auxiliary relay (ZJ), remaining road connection thermal relay (FR), auxiliary relay (ZJ), start button (SB1, SB2), timer (SJ) and A.C. contactor (KM).
Above-mentioned three-phase electricity is electrically connected timer (SJ) by mains switch (K1).
The beneficial effects of the utility model are: the utility model adopts electric elements such as " auxiliary relay ", " thermal relay ", " timer ", finishes the phase failure, overcurrent, protection and the timing start and stop function of motor.Electric elements dependable performances such as " auxiliary relay ", " thermal relay ", " timer ", economy and durability is convenient to maintenance and replacing.Utilize " auxiliary relay " to realize that the advantage of open phase protection is a line clear, action obviously is easy to rapid failure judgement." thermal relay " technology maturation is quick on the draw, and setting value is set simple.This new device has also utilized " timer " function, has realized hyposmosis feed flow deficiency, the intermittently timing start and stop of fuel-displaced oil well, the purpose of played saves energy, reduce labor intensity, increasing work efficiency.
Four, description of drawings:
Accompanying drawing 1 is a circuit connection diagram of the present utility model;
Among the last figure: automatic air-break switch (QS), A.C. contactor (KM), thermal relay (FR), auxiliary relay (ZJ), motor (M), three-phase electricity (L1, L2, L3), fuse (FU1, FU2, FU3), start button (SB1, SB2), timer (SJ, SJ1, SJ2), mains switch (K1).
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model is mainly by automatic air-break switch QS, A.C. contactor KM, thermal relay FR, intermediate relay ZJ, motor M is formed, described motor M is by thermal relay FR, A.C. contactor KM and three-phase electricity L1, L2, L3 is electrically connected, described three-phase electricity L1, L2, two-way among the L3 is by fuse FU1, FU2 connects intermediate relay ZJ, the remaining fuse FU3 of leading up to connects thermal relay FR, intermediate relay ZJ, start button SB1, SB2, timer SJ and A.C. contactor KM, road L3 in the three-phase electricity is electrically connected timer SJ by mains switch K1.
Closed automatic air-break switch QS during use, the intermediate relay ZJ adhesive, auxiliary relay normally opened contact ZJ1 closure is pressed start button SB2, and A.C. contactor KM coil gets electric adhesive, and motor rotation also passes through normally opened contact KM1 maintenance.
Open phase protection principle: because the coil of intermediate relay ZJ is by L1 and L2 power supply; L1; L2 is if then not adhesive of intermediate relay ZJ of the phase failure; auxiliary relay normally opened contact ZJ1 disconnects in the control circuit; motor is out of service, is connected on the L3 owing to control circuit again, as the L3 phase failure; control circuit does not have electricity, and motor can't start or stop running.
The overcurrent protection principle: thermal relay FR is serially connected in the main circuit, raises as make electric current because of somewhere loose contact in electrical fault or the main line, surpasses setting value; the thermal relay action, thermal relay normally closed contact FR disconnects, the control circuit dead electricity; motor is out of service, plays overcurrent protection.
Timing start and stop principle: intermittently fuel-displaced for hyposmosis feed flow deficiency, the oil well that need fix time out, this novel starting drive has adopted in control circuit, installs timer additional, has realized oil pumper timing start and stop function.As figure, the mains switch K1 of the timer that closes sets the start-stop time, and as 23 startups, 6 stop, and timer adopts battery charge, and not being subjected to have a power failure influences.Arrive start-up time, timer contact SJ2 closure, electric motor starting operation.Arrive dwell time, timer contact SJ1 disconnects, and motor is out of service.The motor automatic start-stop is finished SJ1, and SJ2 resets and prepares next period start and stop.
