Abstract
The utility model provides a water filter shaft seal convenient to repair. The water filter seal comprises an antifouling support sleeve, sealing packing and a gland all of which are orderly arranged outside a shaft from bottom upwards, wherein the antifouling support sleeve is fixedly connected to the water filter body; a plurality of O-shaped seal washers are arranged on the contact surface of the antifouling support sleeve with the shaft; and the gland is fixedly connected with the antifouling support sleeve. The water filter shaft seal convenient for repair is simple in structure, and has the characteristics of long service life, low attrition, no leakage, high pressure resistance, automatic elastic compensation on the seal surfaces and the like. Polytetrafluoroethylene is employed; the water filter shaft seal has excellent self-lubricating property; the frictional resistance of the shaft seal is 1/2-1/4 of that of an O-shaped ring; crawling movement at low speed and under low pressure can be eliminated; the service life of more than five years can be guaranteed; the shaft seal can be replaced without splitting the speed reducer and mounting parts thereof in less than 20 minutes; the operation and maintenance cost is greatly reduced; the work load of the maintenance personnel is reduced; the equipment reliability is improved; and the online operation capacity of the water filter is improved.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of water filter axle envelope of being convenient to keep in repair.
Background technique
Domestic majority water filter manufacturer all adopts sealing of " O " type circle or lip-type packing for the main shaft seal of water filter at present, and working life, the following life-span of bad working environments was shorter about 1 year.Seal arrangement takes time and effort in case wearing and tearing and leakage just must be shut down the maintenance replacing, and needed lifting speed reducer and assembly thereof, influences water filter on-line operation ability.
The model utility content
The technical problem that the utility model will solve is for a kind of water filter axle envelope of being convenient to keep in repair is provided, and it is simple in structure, improves equipment reliability, improves water filter on-line operation ability, prolongs the repair cycle, reduces maintenance cost, ensures unit safety stable operation.
The purpose of the utility model is achieved in that
A kind of water filter axle envelope of being convenient to keep in repair; It is included in outer antifouling supporting sleeve, stuffing box packing and the gland of being provided with successively from bottom to up of axle; Described antifouling supporting sleeve is connected on the water filter body; Antifouling supporting sleeve is provided with a plurality of O grommet type seal circles with the axle surface of contact, and said gland and antifouling supporting sleeve are connected.
Above-mentioned antifouling supporting sleeve is connected on the water filter body through bolt.
Technique effect below the utility model has been obtained:
The utility model is simple in structure, and the water filter gland seal device of being convenient to safeguard has long-life, low friction, do not have and leak, characteristics such as high pressure resistant, the automatic elastic compensating of sealing surface.Teflon and have good self-lubricating property, surface friction drag is the 1/2-1/4 of " O " type circle, can eliminate " creeping " phenomenon of moving under low speed, the low pressure.Can guarantee working life more than 5 years; And can under the situation of speed reducer and assembly thereof of not disintegrating, change, less than consuming time 20 minutes reduces operation and maintenance cost greatly; Alleviate the work of maintenance personnel load, improve equipment reliability, improve water filter on-line operation ability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Like Fig. 1-2, a kind of water filter axle envelope of being convenient to keep in repair, it is included in outer antifouling supporting sleeve 1, stuffing box packing 4 and the gland 3 of being provided with successively from bottom to up of axle, and described antifouling supporting sleeve is connected on the water filter body through bolt 2.Antifouling supporting sleeve is provided with a plurality of O grommet type seal circles 5 with the axle surface of contact, and said gland and antifouling supporting sleeve are connected.
The utility model has adopted composite structure, and packing seal 4 is adopted in the upper strata sealing, and the oil immersed type asbestos packing of standard size is adopted in stuffing box packing; Antifouling supporting sleeve 1 is adopted in lower floor's sealing, and sealing material is the O shape circle 5 of teflon, and it act as and forms the water ring sealing, prevents that in sealing dirt impurity from getting into bearing, quickens the wearing and tearing of bearing, has prolonged the working life of bearing greatly.When routine maintenance, the user only need carry out that correcting property is fastening to get final product to the gland stud of upper strata sealing.The sealing material O of lower floor shape circle 5 is embedded in antifouling supporting sleeve 1 inside groove, and antifouling supporting sleeve 1 is through being bolted on the water filter body, and the upper strata packing seal compresses packing gland 3 through regulating bolt 2.
