Abstract
Provided is a mechanical sealing device for a water pump, relating to a water pump sealing device. The utility model solves the problems of high maintenance cost and manpower resource waste because the rubber sleeve is disengaged from the graphite ring to result in water leakage due to the deterioration and fracture of the rubber sleeve under an outside force after a water pump in the mechanical sealing manner of the prior art runs about 1-2 months. The mechanical sealing device includes a movable gasket (1) and a stationary gasket (2) which are successively arranged from the left to the right, and the mechanical sealing device further 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 movable gasket (1). The mechanical sealing device provided reduces the wearing between the movable gasket and the stationary gasket, prevents the water leakage phenomenon, and reduces the waste of the maintenance cost and the manpower resources. The mechanical sealing device provided is suitable to be used in the sealing process of water pumps.
Description
Technical field
The utility model relates to a kind of water pump gland, is specifically related to a kind of mechanical seal device that is used for water pump.
Background technique
Mechanical seal device is the critical piece in the water pump packing process, causes the water pump can not normal operation, befouling environment and waste energy after the Sealing of water pump damages easily.The rotating ring of existing machinery seal arrangement is the form that adopts rubber sleeve to match with graphite annulus, utilizes the elasticity of rubber to contact with stationary ring, thereby realizes airtight water shutoff; Yet at pump operation after 1 month to 2 months; Rotating ring still is in operating condition, and rubber sleeve is broken away from graphite annulus by the fracture of external force deterioration, causes and leaks; Promptly increase maintenance expenses, wasted human resources again.
The model utility content
The purpose of the utility model be for solve the existing machinery seal arrangement at pump operation after 1 month to 2 months; Rubber sleeve is broken away from graphite annulus by the fracture of external force deterioration; Cause and leak; Promptly increase maintenance expenses, waste of manpower problem of resource again, and then a kind of mechanical seal device that is used for water pump is provided.
The technological scheme of the utility model is: a kind of mechanical seal device that is used for water pump comprises motion diaphragm seal and standstill seal sheet; Motion diaphragm seal and standstill seal sheet set gradually from left to right; Said mechanical seal device also comprises setting sleeve and spring; Setting sleeve is dismantled and assembled to be arranged on the pump shaft of water pump, and spring is arranged between setting sleeve and the motion diaphragm seal.
The utility model compared with prior art has following effect: 1. the utility model flexibly, has effectively been regulated the distance between motion diaphragm seal and the standstill seal sheet through spring; The wearing and tearing between motion diaphragm seal and the standstill seal sheet have been reduced; Avoid the generation of water leakage phenomenon, also reduced maintenance expenses and waste of manpower resource.2. after the utility model used device running, do not have in 1 year and leak.3. the utility model is simple in structure, is easy to realize that cost of production is low, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment one: combine Fig. 1 that this mode of execution is described; A kind of mechanical seal device that is used for water pump of this mode of execution comprises motion diaphragm seal 1 and standstill seal sheet 2; Motion diaphragm seal 1 sets gradually with standstill seal sheet 2 from left to right; Said mechanical seal device also comprises setting sleeve 3 and spring 4, and setting sleeve 3 is dismantled and assembled to be arranged on the pump shaft of water pump 5, and spring 4 is arranged between setting sleeve 3 and the motion diaphragm seal 1.
Embodiment two: combine Fig. 1 that this mode of execution is described, the motion diaphragm seal 1 and the standstill seal sheet 2 of this mode of execution are the graphite grazing sheet.So be provided with, wear-resistant, long service life.Other composition is identical with embodiment one with annexation.
Claims (2)
1. mechanical seal device that is used for water pump; It comprises motion diaphragm seal (1) and standstill seal sheet (2); Motion diaphragm seal (1) and standstill seal sheet (2) set gradually from left to right; It is characterized in that: said mechanical seal device also comprises setting sleeve (3) and spring (4), and setting sleeve (3) is dismantled and assembled to be arranged on the pump shaft of water pump (5), and spring (4) is arranged between setting sleeve (3) and the motion diaphragm seal (1).
2. according to the said a kind of mechanical seal device that is used for water pump of claim 1, it is characterized in that: motion diaphragm seal (1) and standstill seal sheet (2) are the graphite grazing sheet.
