Abstract
The utility model relates to a modular upper sealing seat for a protector of an electric submersible pump, which is composed of a modular sealing seat A. One end of the sealing seat A is a mounting point of a lower capsule seat of the protector and the other end is the mounting point of a shaft protecting pipe. A bearing shell B and a mechanical sealing piece chamber are arranged in the inner wall between mounting points of the lower capsule seat of the protector and the shaft protecting pipe. Both ends of the outer wall of the sealing seat A are respectively provided with outer threads which are connected with a housing of the protector, and the middle part is provided with an exhaust hole. Both ends of the exhaust hole are provided with symmetrical sealing grooves and outer stopping openings. The end surface outer edge of the mounting point of the shaft protecting pipe of the sealing seat A is respectively provided with a check valve mounting point and an oil pipe mounting point, wherein a communicating hole is arranged between the check valve mounting point and the exhaust hole. A breathing hole which is parallel to the bearing shell B is arranged between the oil pipe mounting point and the mounting point of the lower capsule seat of the protector. The utility model has the advantages that the specificity design of components is changed into versatility design, and thus the modular upper sealing seat for a protector of an electric submersible pump has better interchangeability; design speed is accelerated, and thus the utility model has the advantages of low cost, easy manufacture, easy assembly, easy repair and structure change of the protector.
Description
(1) technical field:
The utility model relates to a kind of petroleum machinery sealing seat, particularly a kind of submersible electric pump protector modular type upper seal support.
(2) background technique:
At present, the upper seal support of submersible electric pump protector all is to carry out narrow spectrum design at a certain product, and specificity is very strong, and the component purposes that often designs is single-minded, lacks versatility, interchangeability.Be placed on the protector that other places or other plant structure and promptly can not use.As want to change structure and must redesign, increased design cost.Once remodeling will cause some wastes, and cause a lot of difficulties to the repairing of product in earlier stage.So just can not adapt to current society needs fast-developing and that change at any time, also often miss opportunity of sales, the development of restriction submersible electric pump.
(3) summary of the invention:
The purpose of this utility model is to design a kind of submersible electric pump protector modular type upper seal support, and it makes the nonstandard design of selectivity of product become the general modular designs of standard, is a kind of practical nonpetroleum machinery sealing seat.
The technical solution of the utility model: a kind of submersible electric pump protector modular type upper seal support; it is characterized in that it is to be made of modular type sealing seat A; modular type sealing seat A one end is capsule seat installation place under the protector; the other end is for protecting the central siphon installation place; capsule seat installation place and protect in the inwall between the central siphon installation place bearing shell B and mechanical sealing element chamber are housed under the protector; place, modular type sealing seat A outer wall two ends has the outside thread that connects with protector housing respectively; the middle part is an exhaust port; there is the seal groove and the outer stopper of symmetry at the exhaust port two ends; the place, end face outer that protects the central siphon installation place of modular type sealing seat A has one-way valve installation place and oil pipe installation place respectively; between one-way valve installation place and exhaust port intercommunicating pore is arranged, under oil pipe installation place and the protector between capsule seat installation place design the spiracle parallel with bearing shell B arranged.
Above-mentioned said one-way valve installation place can be selected to install one-way valve or one-way valve is not installed.
Above-mentioned said oil pipe installation place can be selected to install long tube or short tube is installed.
Using method of the present utility model is: the one-way valve installation place of this case modular type upper seal support is selected one-way valve is installed, and promptly becomes capsule-type protector modular type upper seal support, does not select to install one-way valve, promptly becomes decanter type protector modular type upper seal support; The oil pipe installation place of upper seal support is selected long tube is installed, and promptly becomes decanter type protector modular type upper seal support, selects short tube is installed, and promptly becomes capsule-type protector modular type upper seal support.
Superiority of the present utility model is: 1, the design of modular type upper seal support success, and changing in the past, the selectivity of component is designed to the versatility design and has good interchangeability; 2, because of the versatility design of product structure, can in design, carry out permutation and combination, accelerate design speed by mathematic(al) mode, increase the structure kind greatly, reduced cost, be easy to production management, be easy to processing, be easy to assembling, be easier to the repairing of protector and change structure; 3, shorten the construction cycle, save development cost; 4, upper seal support changes the versatility alternate configuration into by in the past selectivity utilization structure, can make the product structure kind quantity of protector reach maximum thus; 5, reduce frock, improved technology capability and work efficiency and saved a large amount of man-hours; 6, the structure kind reaches at most, and also can derive from this basis, provides maximum choice to the user, gives preparation the most rational of submersible electric pump system, has also brought into play the best protection performance of protector simultaneously, has prolonged the working life of unit; 7, owing to adopt the protector structure form of standard module design many, client choice as required is big, can obtain rational purchase price, has also reduced the operating cost of unit simultaneously; 8, the design of this standard module success is in time promoted the use of and is made submersible electric pump protector product have good cost performance; 9, market prospects are wide, and product has good competitive capacity, can greatly satisfy customer demand both domestic and external.
(4) description of drawings:
Accompanying drawing is the related a kind of submersible electric pump protector of a utility model modular type upper seal support overall structure schematic representation.
Wherein: A is a upper seal support; B is a bearing shell, and 1 is capsule seat installation place under the protector, and 2 is the outside thread that connects with protector housing; 3 is the mechanical sealing element chamber; 4 is seal groove, and 5 is exhaust port, and 6 is outer stopper; 7 is spiracle; 8 is the one-way valve installation place, and 9 for protecting the central siphon installation place, and 10 is the oil pipe installation place.
(5) embodiment:
Embodiment: (seeing figure) a kind of submersible electric pump protector modular type upper seal support; it is characterized in that it is to be made of modular type sealing seat A; modular type sealing seat A one end is capsule seat installation place 1 under the protector; the other end is for protecting central siphon installation place 9; capsule seat installation place 1 and protect in the inwall between the central siphon installation place 9 bearing shell B and mechanical sealing element chamber 3 are housed under the protector; place, modular type sealing seat A outer wall two ends has the outside thread 2 that connects with protector housing respectively; the middle part is an exhaust port 5; there is the seal groove 4 and the outer stopper 6 of symmetry at exhaust port 5 two ends; the place, end face outer that protects central siphon installation place 9 of modular type sealing seat A has one-way valve installation place 8 and oil pipe installation place 10 respectively; 5 of one-way valve installation place 8 and exhaust ports have intercommunicating pore, and 1 design in capsule seat installation place has the spiracle parallel with bearing shell B 7 under oil pipe installation place 10 and the protector.
