Abstract
The utility model relates to a ceramic seal for water pumps, which belongs to water pump sealing parts. The ceramic seal for water pumps mainly comprises two friction pairs and a spring connecting part, and is characterized in that the friction pair is composed of a ceramic inner ring and a ceramic out ring sleeved with a sealing rubber ring, and the friction pairs and the spring connecting part are sleeved in a transparent oil cup cover. The utility model has low friction coefficient, high wearing resistance, large sealing pressure, fine sealing property and small resistance, and is slight in rotation of a pump shaft. Simultaneously, the transparent oil cup cover is internally filled with lubricating oil, thereby guaranteeing sealing lubrication of the friction pair visually.
Description
Technical field
The utility model belongs to the water pump accessory, particularly a kind ofly is installed in pump body sealing and seals with porcelain.
Background technique
The application area of water pump is very wide, mainly is made up of the pump housing and pump shaft, and pump shaft one end connects drive wheel, the other end stretches into the pump housing by pump housing ending cover hole, connects impeller, thus the impeller rotation, by centrifugal force water delivery operation.Sealing between the pump shaft and the pump housing now generally adopts formation such as filler, machinery envelope to compress sealing, guarantees the relative negative pressure in the pump housing.Sealability is relatively poor, and simultaneously because the pump shaft rotational speed is higher, and frictional force is bigger between the filler, and after long-time the use, this section pump shaft can form certain wearing and tearing, causes pump shaft to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of water pump to seal with porcelain, and sealing is strong, friction is little.
The utility model is achieved in that
Water pump seals with porcelain, mainly is made up of two friction pair, adds spring fastenings between two friction pair, it is characterized in that: each friction pair is made up of ring and ceramic outer ring in the pottery respectively, is set with O-ring seal on the ceramic outer ring; Described two friction pair and spring fastenings are sleeved in the lubricating cup cover by the transparent material making.
After the utility model adopts said structure, seal with the ceramic friction pair of being with O-ring seal, the relative friction ractor of friction pair is little, wear resistance is strong, and is little to the wearing and tearing of pump shaft, the working life of effectively having improved pump shaft; Middle spring fastenings has effectively guaranteed sealing load, good seal performance, and pump shaft rotates light and handy, and resistance is little.Install lubricant oil additional in the transparent lubricating cup cover simultaneously, guaranteed that the sealing of friction pair is lubricated, again intuitively as seen.Have novel structure, practical effect, effectively improved the running quality of whole water pump.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that spring fastenings, 2 is that ceramic interior ring, 3 is that ceramic outer ring, 4 is that cushion rubber, 5 is that lubricating cup cover, 6 is a lubricant oil.
As shown in drawings, the utility model is to seal between a kind of water pump end cap and the pump shaft to seal with porcelain, mainly be made up of two friction pair and a lubricating cup cover 5, each friction pair comprises 2 and round ceramic outer shrouds 3 that cooperate with it of the interior ring of the round ceramic of a ceramic material.Be installed with a pressure spring link 1 between the ring 2 in two potteries, be used to provide sealing load; Be respectively installed with O-ring seal 4 on two ceramic outer ring 3.Described lubricating cup cover 5 adopts transparent material to make, and is beneficial to observation internal operations situation directly perceived.Have an annular groove in lubricating cup cover 5 inner bottom, the profile of this annular groove and described ceramic outer ring 3 is corresponding, and a ceramic outer ring 3 is installed in this annular groove, makes two friction pair and spring fastenings 1 be sleeved in the lubricating cup cover 5.For guaranteeing lubrication effect, add lubricant oil 6 in the lubricating cup cover 5, lubricant oil 6 accounts for 1/3-3/5 of lubricating cup cover 5 volumes, to retain certain cooling space.
During use, ceramic outer ring 3 is installed in the annular groove in the lubricating cup cover 5, puts into a pottery and encircles 2, forms friction pair; Snap in spring fastenings 1 again, the other end of spring fastenings 1 clamps the friction pair that another one is made up of ring 2 and ceramic outer ring 3 in the pottery; Add required lubricant oil 6 in the lubricating cup cover 5.During installation, penetrate pump shaft, be installed at the ending cover hole of the pump housing.O-ring seal 4 on the ceramic outer ring 3 compresses ending cover hole under the effect of spring fastenings 1, make it to form sealing, and O-ring seal 4 also plays a part sealing lubricating cup cover 5 simultaneously, avoids the seepage of the lubricant oil 6 in it.
Claims (3)
