Abstract
The utility model relates to a plunger seal cover, including the plunger, V type sealing washer and U type spring, V type sealing washer has V type opening, the plunger is connected with one side that V type opening is adjacent to V type sealing washer, U type spring include the bulge and with the lug of the both ends body coupling of bulge, the bulge is installed in type opening, the lug is fixed in V type open-ended both sides, V type sealing washer is installed on quiet ring, quiet ring butt rotating ring, the rotating ring is installed on the plunger, rotating ring butt clamping ring, the clamping ring stretches into the bulge of U type spring and compresses tightly U-shaped spring and V type sealing washer. The utility model has the advantages that: a U-shaped spring is arranged between the V-shaped sealing ring and the pressing ring, and a protruding part of the U-shaped spring is in a compressed state in the V-shaped opening. After the V-shaped sealing ring is abraded due to long-time work, the deformation quantity is released by the protruding part of the U-shaped spring, so that the V-shaped sealing ring is attached to the plunger, the abrasion quantity is automatically compensated, and the service life of sealing is prolonged.
Description
Technical Field
The utility model relates to a high-pressure reciprocating pump especially relates to a plunger seal cover.
Background
A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, causing the liquid energy to increase. The pump is mainly used for conveying liquid such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also be used for conveying liquid, gas mixture and liquid containing suspended solid. Pumps can be generally classified by their operating principle into three types, positive displacement pumps, dynamic pumps and other types of pumps. In addition to classification by theory of operation, classification and naming may be by other methods. For example, the driving method may be classified into an electric pump, a turbine pump, and the like; can be divided into a single-stage pump and a multi-stage pump according to the structure; can be divided into a boiler feed pump, a metering pump and the like according to the application; the liquid can be divided into a water pump, an oil pump, a slurry pump and the like according to the property of the transported liquid. According to the structure with or without shaft, the linear pump and the traditional pump can be divided. The water pump can only convey material flow taking fluid as a medium, and can not convey solids.
The prior art pumps require a seal at the plunger. One common sealing method is a V-seal. The V-shaped seal is matched with the pressure ring through the V-shaped seal ring to prevent leakage. However, when the plunger of the high-pressure reciprocating pump moves at a high speed, the V-shaped sealing ring is seriously abraded, and the sealing failure can be caused after long-time use.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a plunger seal cover, solve the problem that V type sealing washer wearing and tearing became invalid.
The utility model discloses a realize through following technical scheme:
the utility model provides a plunger seal cover, includes plunger, V type sealing washer and U type spring, V type sealing washer has V type opening, the plunger is connected with one side that V type opening is adjacent to V type sealing washer, U type spring include bulge and with the lug of the both ends body coupling of bulge, the bulge is installed in the type opening, the lug is fixed in V type open-ended both sides, V type sealing washer is installed on quiet ring, quiet ring butt rotating ring, the rotating ring is installed on the plunger, rotating ring butt clamping ring, the clamping ring stretches into the bulge of U type spring and compresses tightly U-shaped spring and V type sealing washer.
The utility model has the advantages that: a U-shaped spring is arranged between the V-shaped sealing ring and the pressing ring, and a protruding part of the U-shaped spring is in a compressed state in the V-shaped opening. After the V-shaped sealing ring is abraded due to long-time work, the deformation quantity is released by the protruding part of the U-shaped spring, so that the V-shaped sealing ring is attached to the plunger, the abrasion quantity is automatically compensated, and the service life of sealing is prolonged.
Drawings
Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.
In the figure: 1. plunger, 2.V type sealing washer, 3.U type spring, 4. quiet ring, 5. rotating ring, 6 compression ring.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to a plunger seal cover, including plunger 1, V type sealing washer 2 and U type spring 3, V type sealing washer has V type opening, the plunger is connected with one side that V type opening is adjacent to V type sealing washer, U type spring include bulge and with the lug of the both ends body coupling of bulge, the bulge is installed in type opening, the lug is fixed in V type open-ended both sides, V type sealing washer is installed on quiet ring 4, quiet ring butt rotating ring 5, the rotating ring is installed on the plunger, rotating ring butt clamping ring 6, the clamping ring stretches into the bulge of U type spring and compresses tightly U type spring and V type sealing washer.
The utility model has the advantages that: a U-shaped spring is arranged between the V-shaped sealing ring and the pressing ring, and a protruding part of the U-shaped spring is in a compressed state in the V-shaped opening. After the V-shaped sealing ring is abraded due to long-time work, the deformation quantity is released by the protruding part of the U-shaped spring, so that the V-shaped sealing ring is attached to the plunger, the abrasion quantity is automatically compensated, and the service life of sealing is prolonged.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
