Description
Technical field
The present invention relates to oil extraction in oil field lifting equipment submersible electric pump technical field, oiling Quick Connect Kit exempted from by a kind of submersible electric pump sensor specifically.
Background technique
At present, conventional submersible electric pump downhole sensor in the process of going into the well by Flange joint to oil-submersible motor pigtail connection place, sensor test lead-in wire to be gone between with oil-submersible motor asterism by wrap style Placement or contact pin type Placement and is connected.Wrap style connection set operating process more complicated, and limit due to construction site condition, 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 of every parts), be unfavorable for cost control.In addition, because wrap style connection set and contact pin type connection set all can not ensure that in connection procedure, oil-submersible motor inner chamber and sensor inner chamber dynamo oil do not lose, so these two kinds of devices all can not realize scene exempt from oiling function, needs to oil-submersible motor again oiling, reduce the working efficiency of site operation after connection completes.
Summary of the invention
In order to overcome existing submersible electric pump downhole sensor connection set quality of connection difference and cost high and after having connected, need the deficiency of oiling again, 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, the quality of connection of effective raising downhole sensor and oil-submersible motor, and low cost of manufacture.
Technological scheme of the present invention is: oiling Quick Connect Kit exempted from by a kind of submersible electric pump sensor, 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 block on socket, and socket is equipped with spring between block left side and oil-submersible motor lower contact, on socket, block center is equipped with the oil-submersible motor lead-in wire attachment post and terminal pin that are connected, and lead-in wire attachment post left end goes between with oil-submersible motor asterism and is connected,
Described sensor upper connection inside is fixed with block under socket, and under socket, block center is equipped with the female terminal and sensor lead wiring terminal that are connected, and the right-hand member of sensor lead wiring terminal goes between with sensor test and is connected;
On described socket, on block, substantially horizontal has oil-submersible motor oil-through hole, and under socket, on block, 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 by terminal pin and female terminal grafting, only simple Flange joint need be carried out during operation, sensor test can be made to go between to go between from being dynamically connected with oil-submersible motor asterism, 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 block on socket, sensor upper connection inside is equipped with block under socket, respectively oil-submersible motor inner chamber and sensor inner chamber are sealed, to prevent dynamo oil in connection procedure from flowing out, and after connecting, unit inner chamber does not have air, without the need to oiling again, further increase site operation efficiency, also reduce the pollution to environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's oil-submersible motor lower contact when not connecting;
Fig. 2 is the structural representation of the present invention's sensor upper connection when not connecting;
Fig. 3 is the structural representation of coupled condition of the present invention.
1-bolt in figure, the lower contact of 2-oil-submersible motor, 3-asterism goes between, 4-spring, block on 5-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, block under 11-socket, 12-female terminal, 13-sensor lead wiring terminal, 14-sensor test goes between.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1, Fig. 2, oiling Quick Connect Kit exempted from by a kind of submersible electric pump sensor, comprise oil-submersible motor lower contact 2, sensor upper connection 10, oil-submersible motor lower contact 2 inside is equipped with oil-submersible motor asterism lead-in wire 3, sensor upper connection 10 inside is equipped with sensor test lead-in wire 14, described oil-submersible motor lower contact 2 right-hand member internal diameter and sensor upper connection 10 left end external diameter match, and make the two mutually be plugged in together.
Described oil-submersible motor lower contact 2 inner right side is connected with block 5 on socket by bolt 1, and socket matches between block 5 outer wall and oil-submersible motor lower contact 2 inwall, to ensure sealing.On socket, on block 5, substantially horizontal has oil-submersible motor oil-through hole 7, and because oil-through hole 7 aperture is 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.Socket is equipped with spring 4 between block 5 left side and oil-submersible motor lower contact 2, on socket, block 5 center has 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 member is connected with terminal pin 8, and left end and oil-submersible motor asterism go between and 3 to be connected.
Described sensor upper connection 10 inside is fixed with block 11 under socket, and under socket, on block 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 diameter, position matches.Under socket, block 11 center substantially horizontal is equipped with female terminal 12, and the right-hand member of female terminal 12 is connected with sensor lead wiring terminal 13, and right-hand member and the sensor test of sensor lead wiring terminal 13 go between and 14 to be connected.Described female terminal 12 is corresponding with the position of the terminal pin 8 in oil-submersible motor lower contact 2.
Before oil-submersible motor is connected with sensor, on socket, block 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 12, complete oil-submersible motor asterism lead-in wire 3 with sensor test go between 14 connection.Now, on socket, under block 5 and socket, block 11 both ends of the surface contact, rear socket on block 5 joint 10 on a sensor effect under inwardly slide, Compress Spring 4, until connected, connect 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 and down-hole pressure is measured.Because whole connection procedure does not have dynamo oil to flow out from unit inner chamber, also do not have gas to enter unit inner chamber, therefore, this structure achieves in-site installation and exempts from oiling function, and owing to not having dynamo oil to flow out, reduces the pollution to environment.
