Abstract
The utility model discloses a horizontally split surface sealing structure of a horizontally split pump, which comprises a pump body and a sealing groove, wherein the combination position of the horizontally split surface of the pump body and a pump cover is provided with the sealing groove, the sealing groove is internally provided with a sealing ring, and the sealing ring is O-shaped. As for the utility model, all the pump parts except the pump body are not modified, and the modification to the pump body is very small, the sealing groove is milled on the pump body which is originally processed and formed, so that the expense for modification investment is little, and the general standard degree is high; the horizontally split surface sealing groove is internally provided with the O-shaped sealing ring, after the pump is assembled, under the pulling force of an horizontally split surface bolt, the O-shaped sealing ring deforms to play the sealing role, therefore, the high-pressure liquid in a high-lift pump cavity can be effectively prevented from leaking, the problem that a sealing gasket can not be reused is solved, simultaneously, both the assembling speed of the pump and the reliability of the whole unit during operation are improved.
Description
Technical field:
The utility model relates to the middle-opening pump field of sealing technology, relate in particular to a kind of middle-opening pump in open surface seal structure.
Background technique:
The single-stage double-suction centrifugal pump of early stage design generally all is big flow low lift, lift is mostly below 125m, in to open face seal all be to rely on the thick fish paper pad of 0.25mm to seal, significant limitation is arranged, for example it can only be used for the face seal of opening of low-lift pump; Whole pump to be disintegrated during for easily damaged partss such as water pump replacing impeller, axle sleeves, opening the face seal pad in on-the-spot the discovery all damages after pump disintegrates, so sealing gasket can only use once mostly, can not reuse, cause very big trouble when therefore keeping in repair pump at the scene.This sealing gasket is opened in pump factory also slowly is placed on fish paper by the master worker and is pounded out on the face, therefore sealing gasket system to make efficient lower, thereby influenced the efficiency of assembling of water pump to a certain extent, middle-opening pump demand to high-lift is very big in the market, and the single-stage double-suction pump is gradually to the high-lift development of big flow.In open face sealing very big design improvement never, but use blue or green shell sealing gasket can not satisfy seal request for high-lift middle-opening pump.
Recently, have many clients also advise with in open face sealing do some improvement, will damage and can only use once because of the pump back sealing gasket that disintegrates, pump use field fabrication is very inconvenient again.Consider from design angle, use the fish paper pad can not satisfy seal request to high-lift pump, for this reason, it is very urgent to propose to open in novel face seal.Open face seal pad during some factory incites somebody to action for this reason and be improved to asbestos packing sheet, though this improvement can solve high-lift or pump pump high-temp liquid in open the face seal problem but a lot of shortcomings arranged, for example the thickness of asbestos packing sheet thickening simultaneously its intensity and toughness also improve thereupon, success rate and speed were lower than fish paper sealing gasket when the assembling master worker made this sealing gasket.Can largely influence the water pump assembling speed.And can not reuse, therefore this improvement neither optimally design.
The utility model has been done a very little improvement for the pump housing of middle-opening pump (all horizontal, vertical classes), in the pump housing, open and be milled with a seal groove on the face, the O RunddichtringO is housed in seal groove, be used for effectively preventing that high-head pump pump chamber mesohigh liquid from revealing outside pump chamber, also having solved the conventional seals pad can not reusable problem.
The model utility content:
The purpose of this utility model provide a kind of middle-opening pump in open surface seal structure, be used for effectively preventing that high-head pump pump chamber mesohigh liquid from revealing outside pump chamber, also having solved the conventional seals pad can not reusable problem.
The technical solution of the utility model is as follows:
Open surface seal structure in a kind of middle-opening pump, comprise the pump housing, seal groove, it is characterized in that: open in the described pump housing on the face and be provided with seal groove, in the described seal groove seal ring is installed with the pump cover junction.
Open surface seal structure in the described middle-opening pump, it is characterized in that: described seal ring is the O RunddichtringO.
The beneficial effects of the utility model are:
1. a whole pump component other part except that the pump housing is changed is not all changed, and the change of the pump housing is also very little, is milled with seal groove on original pump housing that machines, and it is few therefore to transform the expense that drops into, universal standardization degree height.
2. open in the O RunddichtringO is housed in the face seal groove, pump assembling back in open and under the tension of face bolt the O RunddichtringO be out of shape to play seal action, prevented that effectively high-lift pump pump chamber mesohigh liquid from outwards revealing, also having solved sealing gasket can not reusable problem, improved the pump assembling speed simultaneously, and the reliability when having improved whole unit operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Open surface seal structure in a kind of middle-opening pump, comprise the pump housing 1, seal groove 2, open in the pump housing 1 on the face and be provided with seal groove 2 with the pump cover junction, seal ring 3 is installed in the seal groove 2, seal ring 3 is the O RunddichtringO.
Seal groove 2 is symmetrical structure on the pump housing, after in O RunddichtringO 3 is installed on seal groove 2, the upper end that again pump cover is installed on the pump housing 1 compresses, in open and make 3 distortion of O RunddichtringO play seal action under the tension of face bolt, prevented that effectively high-lift pump pump chamber mesohigh liquid from outwards revealing, also having solved sealing gasket can not reusable problem.
Claims (2)
- A middle-opening pump in open surface seal structure, comprise the pump housing, seal groove, it is characterized in that: open in the described pump housing on the face and be provided with seal groove, in the described seal groove seal ring is installed with the pump cover junction.
