Abstract
The water-suction-discharge section of a pump comprises a suction chamber and a discharge chamber the two of which are formed by two concentric circles, the inner circle chamber is as suction chamber and the outer circle chamber is as discharge chamber. The suction chamber is communicated with an inlet tube by a closed passage and the discharge chamber is directly communicated with an outlet tube. One end of the pump axle passes through the suction chamber and connects with the motor axle and the other end connects with the impeller. There is provided with a sealing device at the connection part of the pump axle and the suction chamber. The invention radically solves the problem in existing technology that mechanical sealing device set in high pressure area needs bearing whole pressure produced by impeller so as to reduce the structure request of sealing device for bearing high pressure and increase the reliability and service life of sealing device.
Description
Technical field
The present invention relates to pump part and make the field, mainly is a kind of pump water inlet-outlet segment with detachable mechanical sealing structure.
Background technique
Be not with the sealing mounting structure on the water inlet-outlet segment of present existing pump or the pump housing, sealing all is to be contained on the pump cover that matches with the water inlet-outlet segment or the pump housing, promptly is positioned at the position, the back side of impeller.Sealing is in the delivery chamber zone of high pressure of the water inlet-outlet segment or the pump housing.Its deficiency: the one, sealing need be born the high pressure that impeller produces, and the specific pressure that sealing is born increases, and shorten working life.The 2nd, the applying working condition of sealing is restricted, and can not be used for high voltage structures or ultrahigh pressure structure.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of pump water inlet-outlet segment with detachable mechanical sealing structure is provided.
The present invention solves the technological scheme that its technical problem adopts: the pump water inlet-outlet segment of this band detachable mechanical sealing structure, mainly comprise water inlet-outlet segment, the suction chamber of described water inlet-outlet segment and delivery chamber are made of inside and outside two concentric circles, the internal round chamber body is as suction chamber, the cylindrical cavity is as delivery chamber, wherein suction chamber is connected with inlet tube by the runner of sealing, and delivery chamber then directly is connected with outer pipe; One end of pump shaft passes with motor shaft from suction chamber and is connected, and the other end is connected with impeller; The joint of pump shaft and suction chamber is provided with seal arrangement.
The effect that the present invention is useful is: fundamentally solved the problem that the mechanical seal that exists in the background technique is positioned at the zone of high pressure, need bears whole pressure that impeller produces.Thereby reduced the structural requirement that sealing is born high pressure, improved the reliability and the working life of sealing.
Description of drawings
Fig. 1 is a mounting structure cross-sectional schematic of the present invention;
Fig. 2 is the structural representation of looking up of the present invention;
Description of reference numerals: inlet tube 1, water inlet-outlet segment 2, suction chamber 3, seal arrangement 4, pump shaft 5, delivery chamber 6, outer pipe 7, impeller 8.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As illustrated in fig. 1 and 2, the pump water inlet-outlet segment of this band detachable mechanical sealing structure, mainly comprise water inlet-outlet segment 2, the suction chamber 3 of described water inlet-outlet segment 2 and delivery chamber 6 are made of inside and outside two concentric circles that are provided with at grade, the internal round chamber body is as suction chamber 3, the cylindrical cavity is as delivery chamber 6, and wherein suction chamber 3 is connected with inlet tube 1 by the runner of sealing, and delivery chamber 6 then directly is connected with outer pipe 7; One end of pump shaft 5 passes with motor shaft from the center 3 of suction chamber and is connected, and the other end is connected with impeller 8; Pump shaft 5 is provided with seal arrangement 4 with the joint of suction chamber 3.
The top of installation process: Fig. 1 is a motor side, and bottom is an overcurrent part side in the pump, and water inlet-outlet segment 2 is installed on the electric machine support, and hydraulic parts such as impeller 8 and stator are installed then.Again mechanical seal device 4 from the back side, the electric machine support of water inlet-outlet segment 2 pump shaft 5 of packing into, pump shaft 5 adopts coupling to be connected with motor shaft.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
