Description
Technical field
The present invention relates to oil extraction in oil field lifting equipment submersible electric pump technical field, a kind of submersible electric pump sensor is exempted from oiling Quick Connect Kit specifically.
Background technique
At present, conventional submersible electric pump downhole sensor is connected to oil-submersible motor afterbody joint by flange in the process of going into the well, and sensor test lead-in wire is connected with oil-submersible motor asterism lead-in wire by wrap style Placement or contact pin type Placement.Wrap style connection set operating process more complicated, and because job site condition is limit, quality of connection is easily affected; The operation of contact pin type connection set is fairly simple, but contact pin cost higher (about three or four thousand yuan every) is unfavorable for cost control.In addition, because wrap style connection set and contact pin type connection set all can not guarantee oil-submersible motor inner chamber and the not loss of sensor inner chamber dynamo oil in connection procedure, so these two kinds of devices all can not be exempted from oiling function in the scene of realizing, need to, to oil-submersible motor again oiling after connection completes, reduce the working efficiency of site operation.
Summary of the invention
In order to overcome that existing submersible electric pump downhole sensor connection set quality of connection is poor and cost is high and need the deficiency of oiling again after connection to complete, the invention provides a kind of submersible electric pump sensor and exempt from oiling Quick Connect Kit, what this submersible electric pump sensor exempted from that oiling Quick Connect Kit can realize oil-submersible motor and downhole sensor exempts from the quick linkage function of oiling, significantly reduce field operation amount, effectively improve the quality of connection of downhole sensor and oil-submersible motor, and low cost of manufacture.
Technological scheme of the present invention is: a kind of submersible electric pump sensor is exempted from oiling Quick Connect Kit, comprise oil-submersible motor lower contact, sensor upper connection, oil-submersible motor lower contact inside is equipped with oil-submersible motor asterism lead-in wire, sensor upper connection inside is equipped with sensor test lead-in wire, described oil-submersible motor lower contact inner right side has been bolted piece on socket, and between piece left side and oil-submersible motor lower contact, be equipped with spring on socket, on socket, piece center is equipped with oil-submersible motor lead-in wire attachment post and the terminal pin being connected, and lead-in wire attachment post left end is connected with oil-submersible motor asterism lead-in wire,
Described sensor upper connection inside is fixed with piece under socket, and under socket, piece center is equipped with female terminal and the sensor lead wiring terminal being connected, and the right-hand member of sensor lead wiring terminal is connected with sensor test lead-in wire;
On described socket, on piece, substantially horizontal has oil-submersible motor oil-through hole, and under socket, on piece, substantially horizontal has sensor oil-through hole, and oil-submersible motor oil-through hole and sensor oil-through hole position match.
The present invention has following beneficial effect: owing to taking such scheme, this connection set is pegged graft by terminal pin and female terminal, during operation, only need carry out simple flange connection, can make sensor test lead-in wire and oil-submersible motor asterism lead-in wire certainly be dynamically connected, simple to operate, quality of connection is reliable, and low cost of manufacture.Simultaneously, the oil-submersible motor lower contact inside of this connection set is equipped with piece on socket, sensor upper connection inside is equipped with piece under socket, respectively oil-submersible motor inner chamber and sensor inner chamber are sealed, to prevent that in connection procedure, dynamo oil flows out, and after connecting, unit inner chamber does not have air, without oiling again, further improve site operation efficiency, also reduced the pollution to environment.

1-bolt in figure, the lower contact of 2-oil-submersible motor, 3-asterism lead-in wire, 4-spring, piece in 5-gang socket, 6-motor down-lead attachment post, 7-oil-submersible motor oil-through hole, 8-terminal pin, 9-sensor oil-through hole, the upper connection of 10-sensor, piece under 11-gang socket, 12-female terminal assembly, 13-sensor lead attachment post, 14 sensor test lead-in wires.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1, Fig. 2, a kind of submersible electric pump sensor is exempted from oiling Quick Connect Kit, comprise oil-submersible motor lower contact 2, sensor upper connection 10, oil-submersible motor lower contact 2 inside are equipped with oil-submersible motor asterism lead-in wire 3, sensor upper connection 10 inside are equipped with sensor test lead-in wire 14, described oil-submersible motor lower contact 2 right-hand member internal diameters and sensor upper connection 10 left end external diameters match, and the two can be plugged in together mutually.
Described oil-submersible motor lower contact 2 inner right side are connected with piece 5 on socket by bolt 1, match, to guarantee sealing on socket between piece 5 outer walls and oil-submersible motor lower contact 2 inwalls.On socket, on piece 5, substantially horizontal has oil-submersible motor oil-through hole 7, and because oil-through hole 7 apertures are less, under capillary effect, dynamo oil can not flow out from oil-through hole, does not also have gas and enters into oil-submersible motor inner chamber and sensor inner chamber.On socket, between piece 5 left sides and oil-submersible motor lower contact 2, be equipped with spring 4, on socket, piece 5 centers have the through hole of substantially horizontal, hole is built-in with oil-submersible motor lead-in wire attachment post 6, and oil-submersible motor lead-in wire attachment post 6 right-hand members are connected with terminal pin 8, and left end is connected with oil-submersible motor asterism lead-in wire 3.
Described sensor upper connection 10 inside are fixed with piece 11 under socket, and under socket, on piece 11, substantially horizontal has sensor oil-through hole 9, and described sensor oil-through hole 9 is identical with oil-submersible motor oil-through hole 7 diameters, position matches.Under socket, piece 11 center substantially horizontals are equipped with female terminal 12, and the right-hand member of female terminal 12 is connected with sensor lead wiring terminal 13, and the right-hand member of sensor lead wiring terminal 13 is connected with sensor test lead-in wire 14.Described female terminal 12 is corresponding with the position of terminal pin 8 in oil-submersible motor lower contact 2.
Before oil-submersible motor is connected with sensor, in gang socket, piece 5 outwards ejects under the effect of spring 4, when oil-submersible motor is connected with sensor, first, terminal pin 8 is inserted in female terminal assembly 12, completes oil-submersible motor asterism lead-in wire 3 and sensor test and goes between 14 be connected.Now, in gang socket, under piece 5 and gang socket, piece 11 both ends of the surface contact, in gang socket, piece 5 inwardly slides under the effect of sensor upper connection 10 afterwards, Compress Spring 4, until connected, connected rear oil-submersible motor inner chamber and sensor inner chamber and realized pressure balance by oil-submersible motor oil-through hole 7 and sensor oil-through hole 9, do not affected sensor down-hole pressure is measured.Because whole connection procedure has dynamo oil, from unit inner chamber, do not flow out, also do not have gas to enter unit inner chamber, therefore, this structure has realized on-the-spot installation and has exempted from oiling function, and owing to not having dynamo oil to flow out, has reduced the pollution to environment.
