Description
Technical field
The utility model relates to a kind of drive pump, relates in particular to a kind of magnetic drive pump.
Background technique
Magnetic drive pump in currently available technology relies on the non-contact transmission of magnetic force, is two sections by the axle of common motive sealing pump from sealing punishment, and shaft extension does not need to penetrate seal casinghousing, has complete leak free advantage.But also, just because of the rotor of magnetic drive pump in seal chamber needs the lubricated bearings of medium, the running clearance of bearing is very little, and makes common magnetic drive pump be only applicable to the conveying of cleaning medium.
In some fed sheet of a media, may contain a small amount of solids backflow, as the iron rust etc. in the silt in water, device.Although be a small amount of or micro-, once enter in sliding bearing, may cause the stuck fault of bearing or heavy wear and shorten the life-span.Therefore should prevent that solids backflow from entering into the part flowing liquid of cooling or lubricating bearings.
The measure of traditional anti-backflow wearing and tearing is, on pump inlet pipeline, filter is set.But because the perforate of filter can not be too little, otherwise liquid flowing resistance is too large, and easily cause filter cavity to stop up, cause the cavitation of pump or find time.And if once magnetic drive pump cavitation or find time and not in time do not shut down can cause that Magnetic Drive Pump Sliding Bearing is damaged, separation sleeve is not because having cooling liquid excess Temperature to cause magnet rotor demagnetization fault equally.The filter that perforate is larger can not stop that the solids backflow of reduced size enters the part stream for cooling and lubricating, therefore little to the effect of protection bearing.And if filter is placed in to part circulation road, although can not cause impeller inlet to stop up and the fault that causes, may cause part stream cooling because plugged filter can not get separation sleeve, the too high and fault of demagnetization of magnetic driver temperature rise; Sliding bearing is unavailable lubricated and dry running is cracked.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact structure is provided, and can make the solids backflow that damages bearing discharge, and can make again the magnetic drive pump of liquid lubricating bearings.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of magnetic drive pump, comprise hitch, the top of described hitch is provided with motor, the bottom of described hitch is provided with the pump housing, between the described pump housing and hitch, be provided with pump cover, in described hitch, be provided with outer magnet rotor, top and the motor of described outer magnet rotor are fixedly connected, in described outer magnet rotor, be provided with interior magnet rotor, between described interior magnet rotor and outer magnet rotor, be provided with separation sleeve, in described interior magnet rotor, be provided with pump shaft, the afterbody of described pump shaft is provided with impeller, described pump shaft extends pump cover downwards, between described pump cover and pump shaft, be provided with bearing support, the inwall of described bearing support top and bottom respectively and between pump shaft, be provided with bearing housing, between the top of described bearing housing and the bottom of interior magnet rotor, between bearing housing and impeller, be respectively equipped with thrust button, described separation sleeve and pump cover fix, between described impeller and pump cover, form clearance seal by casing wear ring, between described impeller inwall and pump cover, form introduction passage, described impeller inwall and casing wear ring outer wall form impeller seals czermak space, described casing wear ring outer wall and pump cover inwall form extraction channel, in described pump cover, be provided with guiding runner, described bearing support outer wall, between pump cover and interior magnet rotor, form and collect cavity, between the upper end outer wall and interior magnet rotor of described bearing support, between bearing support and thrust button, be provided with guide channel, in described impeller, be provided with and portal, described introduction passage, impeller seals czermak space, extraction channel, guiding runner, collect cavity, guide channel forms first medium lubrication channel, between described interior magnet rotor and separation sleeve, form rotor channel, in described pump shaft, be provided with return flow line, in described impeller, be provided with backflow discharge route, described described introduction passage, impeller seals czermak space, extraction channel, guiding runner, collect cavity, rotor channel, return flow line, backflow discharge route forms the second backflow discharge route.
As preferably, between described impeller and the pump housing, seal mutually by casing ring, between the described pump housing and pump cover, be respectively equipped with sealing gasket between pump cover and separation sleeve.
As preferably, between described bearing support and pump cover, between separation sleeve and pump cover, between the pump housing and hitch, fix by bolt respectively between hitch and motor, between described pump shaft and interior magnet rotor, lock mutually by lock-nut.
The radial clearance of impeller seals czermak space is very little, is generally 0.15～0.25mm, and therefore, impeller seals czermak space is exactly one threshold, and the solids backflow that is greater than sealing ring gap just enters not go;
Due to the centrifugal action that is subject to vane rotary and causes, the heavy solids containing in medium refluxes and is thrown toward centrifugal force direction and separates, and clean liquid is introduced in the impeller seals czermak space in inner side, for separation sleeve provides cooling liquid, for bearing provides lubricated.
Owing to relatively rotating between impeller ring and casing wear ring, although therefore gap is very little, and stop up never, having guaranteed between on-stream period provides cleaning medium uninterrupted for separation sleeve and sliding bearing.
The utility model provides a kind of magnetic drive pump, and compact structure, provides better usability at extension device working life, increases work efficiency.
