Description

Middle-open-face sealing gasket of water pump

Technical Field

The application relates to the technical field of sealing gaskets, in particular to a split sealing gasket in a water pump.

Background

The cloisonne electric pumping irrigation engineering (called scene electric engineering for short) in Gansu province is a large II-type electric pumping irrigation engineering with cross-province, high lift, multi-step and large flow. Wherein, there is pump station 43 seats, there are all kinds of model water pump 263 platform covers, mainly regard double suction centrifugal pump as the main. Because the media pumped by the double-suction centrifugal pump contain a large amount of silt, overflowing parts such as an impeller, a sealing ring and the like are quickly abraded and have short service life, a pump cover needs to be uncovered for maintenance in each filling season, and the overflowing parts need to be periodically replaced to meet the normal operation of the system.

The double-suction centrifugal pump is overhauled on site, after the pump cover is opened, the sealing gasket on the middle opening surface generally needs to be replaced again, the sealing gasket manufacturing process is complex, the pump cover needs to be lifted by lifting equipment, the inner side of the pump cover is turned up, raw materials for manufacturing the sealing gasket are flatly laid on the pump cover of the water pump, along the contour of the middle opening surface of the water pump, an iron hammer is used for knocking the raw materials to obtain contour traces of the joint surface of the pump cover of the water pump, and then the sealing gasket consistent with the contour traces of the middle opening surface of the water pump is cut by scissors along the contour traces. Otherwise, when the water pump works, the high-pressure area stabs water to the low-pressure area, and the joint surface of the water pump is broken. In the process of manufacturing the sealing gasket, the difficulty of turning over the pump cover is high, potential safety hazards exist, the precision is high, and time and labor are wasted.

However, when the sealing gasket of the open face in the water pump is used, mechanical grease is usually applied to the joint face of the water pump and the sealing gasket, so that the sealing gasket is prevented from being damaged due to adhesion to the open face in the water pump when the open face in the water pump is opened in the maintenance process and the sealing gasket is extruded by tightening a screw of the pump cover and soaked in the water pump. However, the sealing gasket is easily damaged due to the fact that the screw of the pump cover tightly presses the sealing gasket, and the sealing gasket is soaked in the water pump for a long time. Therefore, no matter the service time of the sealing gasket is long, the sealing gasket can be damaged only by opening the pump cover of the water pump, and the sealing gasket needs to be machined again.

Fig. 1 shows a schematic structural diagram of an open-face gasket in a water pump according to an embodiment of the present application.

The split-surface sealing gasket comprises a sealing gasket body, wherein a plastic protective layer used for increasing strength and sealing performance is arranged on one side of the sealing gasket body, and a lubricating oil coating is arranged on the upper surface of the plastic protective layer.

The sealing gasket body is characterized in that a plastic protective layer is arranged on one side of the sealing gasket body far away from the middle opening surface of the pump body, and the plastic protective layer is usually a plastic film so as to isolate the sealing gasket from the middle opening surface of the water pump. Meanwhile, the plastic film has strong corrosion resistance and wear resistance, so that the service life of the sealing gasket can be greatly prolonged, and the problem that the sealing gasket is easily adhered to the water pump to be damaged when the pump cover of the water pump is opened is further solved. Be provided with the lubricating oil coating on one side of the plastics protective layer that is close to the pump cover to realize improving the lubricity of sealed pad, reduce the impaired risk of sealed pad.

It should be noted that: the shape of the plastic protective layer is consistent with that of the sealing gasket body, wherein the plastic protective layer is formed by cutting according to the middle opening surface of the water pump.

In some embodiments, the gasket body comprises an inner layer and an outer layer wrapping the inner layer, wherein the inner layer is made of highland barley paper or asbestos pad material, and the outer layer is made of butter coating. In some embodiments, the gasket body is further provided with a plurality of bolt positioning holes.

Wherein, the butter coating is in order to prevent that the water pump from opening the face in the water pump in the maintenance process, and sealed pad is because of the adhesion to the face and be damaged in the water pump.

Generally, the seal pad body is formed by knocking highland barley paper or an asbestos pad material by an iron hammer to leave a contour trace of a joint surface of the water pump cover, and cutting the seal pad body on the highland barley paper or the asbestos pad by scissors along the contour trace. The shape of the sealing gasket body is consistent with that of the middle opening surface of the water pump, otherwise, the water pump can be damaged by water stabbed from the high-pressure area to the low-pressure area when in work.
