specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 This embodiment is described. A mechanical seal device for a water pump in this embodiment includes a moving sealing plate 1 and a stationary sealing plate 2. The moving sealing plate 1 and the stationary sealing plate 2 are sequentially arranged from left to right. The mechanical sealing device It also includes a positioning sleeve 3 and a spring 4, the positioning sleeve 3 is detachably arranged on the pump shaft of the water pump 5, and the spring 4 is arranged between the positioning sleeve 3 and the moving sealing plate 1.

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 This embodiment will be described. Both the moving sealing sheet 1 and the stationary sealing sheet 2 in this embodiment are graphite sealing sheets. With such setting, it is wear-resistant and has a long service life. Other compositions and connections are the same as in the first embodiment.

Abstract

The invention relates to a mechanical sealing device for a water pump, relating to a water pump sealing device, and solving problems of increase of maintenance cost and waste of manpower resources due to water leakage caused by separation of a rubber sleeve from a graphite ring due to outer force deteriorated breakage after a water pump runs for one to two months in the traditional mechanical seal. The mechanical sealing device comprises a movable sealing sheet (1) and a fixed sealing sheet (2) which are sequentially arranged from left to right. The mechanical sealing device further comprises a locating sleeve (3) and a spring (4), wherein the locating sleeve (3) is detachably arranged on a pump shaft of a water pump (5), and the spring (4) is arranged between the locating sleeve (3) and the movable sealing sheet (1). According to the mechanical sealing device for the water pump, disclosed by the invention, abrasion between the movable sealing sheet and the fixed sealing sheet can be reduced, water leakage situation is avoided, and the wastes on maintenance cost and manpower resource can be also reduced. The mechanical sealing device for the water pump, disclosed by the invention, is suitable for a sealing process of the water pump.

Description

technical field [0001] The invention relates to a water pump sealing device, in particular to a mechanical sealing device for a water pump. Background technique [0002] The mechanical seal device is the main part in the sealing process of the water pump. If the seal of the water pump is damaged, it will easily cause the water pump to malfunction, pollute the environment and waste energy. The dynamic ring of the existing mechanical seal device is in the form of matching the rubber sleeve and the graphite ring, and uses the elasticity of the rubber to contact the static ring to achieve airtight water sealing. However, after the water pump has been running for 1 to 2 months, the dynamic ring It is still in the running state, but the rubber sleeve is degraded by external force, breaks and separates from the graphite ring, causing water leakage, which increases maintenance costs and wastes human resources. Contents of the invention [0003] The purpose of the present inventio...
