Abstract
The utility model discloses a high -efficient stable -type stator device of centrifugal pump, including pump middle section (1), stator (3) neck bush (2) are equipped with between pump middle section and the stator water conservancy diversion sealing ring (4) are equipped with in the hole department of pump middle section and neck bush. The stator department of being close to of water conservancy diversion sealing ring (4) has smooth fillet (7) of passing through, the water conservancy diversion sealing ring passes through screw (5) dress on pump middle section (1). Adorn in the neck bush stator after reforming transform and can be under the unchangeable condition of the pump middle section of former centrifugal pump mounting dimension cooperate with the pump middle section, for fluid after the stator transformation carries out the transition to the next stage better, more uniformly, make efficiency of pump loss minimum, this water conservancy diversion sealing ring forms sealed pair of friction with the impeller choma department of centrifugal pump, can play the refluence of effective prevention next stage pressurization medium again and return supreme one -level, has improved the stability of pump operation.
Description
Technical field
This utility model relates to a kind of centrifugal pump, is specifically related to one and adapts to centrifugal multistage pump multiple centrifugal pump
Stator apparatus.
Background technology
At present, the water injection technology in some oil fields changes greatly, first wife overlap the output pressure of water injecting pump with
Flow margin space is very big, as used outlet regulating valve excessively to regulate, the efficiency of pump can be caused too low,
It runs also unstable, thus results in energy dissipation, can have a strong impact on cost for oil production.It is satisfied
Centrifugal water-injection pump fall holds transformation, in line with principle of simplifying administration and practicing economy, utilizes zero, water-injection station original annotation water pump
Transformation it is updated on the basis of part and plumbing arrangements.For meeting in transformation process its basis not
In the case of change, a kind of stator apparatus adapting to multiple centrifugal multistage pump multiple centrifugal pump need to be designed, this transformation
Method can significantly improve the stability that water injecting pump runs, and can save again substantial amounts of capital expenditure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of high efficiency, fortune
The efficient stable formula stator apparatus of the centrifugal pump of line stabilization.
This utility model purpose realizes by following technical solution: the efficient stable formula of centrifugal pump
Stator apparatus, including pump stage casing, stator, equipped with neck bush between described pump stage casing and stator,
Equipped with water conservancy diversion sealing ring at the endoporus of described pump stage casing and neck bush.
Having the fillet smoothly transitted at the close stator of described water conservancy diversion sealing ring, described water conservancy diversion is close
Seal ring is contained on pump stage casing by screw.
After using this utility model, being loaded on improved stator in neck bush can be at former centrifugal pump
Matching with pump stage casing in the case of pump stage casing installation dimension is constant, after transforming for stator, fluid is more
Well, more uniformly it is transitioned into next stage, makes efficiency of pump loss reduction；This water conservancy diversion sealing ring with from
Friction sealed pair (diameter is about 0.45mm～0.60mm) together is formed at the impeller port ring of heart pump,
Can play again and effectively stop the refluence of next stage high pressure sealing medium to be back to upper level, improve
The stability of pump operation.
Accompanying drawing explanation
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the efficient stable formula stator apparatus of this utility model centrifugal pump.
Detailed description of the invention
Understand with reference to Fig. 1, the efficient stable formula stator apparatus of this utility model centrifugal pump, including
Pump stage casing 1 (being illustrated as wherein one section), stator 3, between described pump stage casing 1 and stator 3
Equipped with neck bush 2, equipped with water conservancy diversion sealing ring at the endoporus of described pump stage casing 1 and neck bush 2
4.At the close stator of described water conservancy diversion sealing ring 4, (i.e. the left side shown in Fig. 1) has smooth
The fillet 7 of transition (corresponding with at impeller eye, uniform for guaranteeing stator back of the body runner flow-passing surface
Be transitioned into impeller eye, make upper level liquid medium under impeller high velocity effect by stator and
Water conservancy diversion sealing ring flow velocity is transitioned into next stage impeller eye equably, hence it is evident that improve the efficiency of pump),
Described water conservancy diversion sealing ring 4 is contained on pump stage casing 1 by screw 5.
Described water conservancy diversion sealing ring 4 and sealing surface 6 thereof are straight together with being formed at next stage impeller port ring
Footpath is the friction sealed pair of 0.45mm～0.60mm, can effectively stop next stage high pressure sealing to be situated between
Matter flows backwards and is back to upper level.
