Abstract
The utility model provides an evacuation proofing magnetic transmission pump that can make the medium in the bearing box circulate and is provided with double cooling system. The utility model is increased with a small impeller and a water cooling pipe coil double cooling system which are not provided in the common magnetic force drive pump; wherein the water cooling pipe coil system not only has the cooling function to the circular media in the bearing box but also directly cools an external magnetic cylinder and an isolation sleeve. When the pump is evacuated and is normally running, the front and back bearings and the internal and external magnetic cylinders can be well lubricated and cooled and cannot have the phenomenon that temperature is excessively high, bearing is abrased and internal and external magnetic cylinder are burned out, so the magnetic pump has the evacuation proofing capacity.
Description
Technical field
The utility model belongs to chemical machinery field, relates to a kind of magnetic drive pump, relates in particular to a kind of magnetic drive pump with anti-pumpage.
Background technique
Magnetic drive pump is owing to replaced coupling, mechanical seal device with the separation sleeve between inside and outside magnet steel and inside and outside magnet steel, change is sealed into static seal, fundamentally solved the seal leakage problem of pump, therefore magnetic drive pump has leak free advantage, is used widely in industries such as petrochemical industries.But, magnetic drive pump also has fatal defective: under the pump depletion state, forward and backward bearing and inside and outside magnetic cylinder be not owing to there is the lubricated and cooling of medium, the very fast rising of temperature, cause bearing wear, magnetic cylinder to burn out, need often to change, improved the user cost of magnetic drive pump greatly, simultaneously because frequent bearing and the magnetic cylinder changed influenced working efficiency.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that conventional magnetic drive pump can not move under evacuated, a kind of magnetic drive pump with anti-pumpage to be provided.
The anti-magnetic drive pump of finding time of the present utility model comprises pump assembly, bearing box assembly, magnetic driver and runs through the rotor assembly of the pump housing, bearing housing, cooling tank assembly that the rotor assembly in its middle pump body is provided with impeller successively; Rotor assembly in the bearing box assembly is provided with forward and backward bearing, is provided with small impeller between the forward and backward bearing, and forward and backward bearing outer ring is provided with the aqueous cold plate guard system; Magnetic driver comprise interior magnetic cylinder, outer magnetic cylinder and be located in separation sleeve between the magnetic cylinder, outer magnetic cylinder.
The utility model is compared with the prior art has following advantage:
Owing between the forward and backward bearing on the bearing housing internal rotor assembly, be provided with small impeller, make the medium in the bearing housing produce enough pressure, thereby media flow is entered in interior magnetic cylinder and the separation sleeve annular space by cooling tank assembly, flow in the small impeller by the main shaft endoporus again, form circulation, simultaneously, the medium that flows in the bearing housing with the small impeller outlet port constantly exchanges, the circuit medium is walked the eddy current torrid zone that produces in the separation sleeve, plays the effect of interior magnetic cylinder of cooling and separation sleeve.When pump depletion, the axial force that the rotation of small impeller produces, promoting the forward thrust dish compresses place, fore bearing medium inlet, in bearing housing, form the dielectric space of a sealing, this space is owing to there is the cooling of water-cooled coil pipe, the externally cooling of magnetic cylinder, separation sleeve of aqueous cold plate guard system itself in addition, medium temperature can sharply not raise, when pump runs well, forward and backward bearing, inside and outside magnetic cylinder can both obtain well lubricated and cooling, can not exist temperature too high, the phenomenon that bearing wear, inside and outside magnetic cylinder burn out, thus make magnetic drive pump have anti-pumpage.
Adopt the design of aqueous cold plate guard system, not only circuit medium in the bearing housing is played cooling action, simultaneously, directly externally magnetic cylinder, separation sleeve cool off the aqueous cold plate guard system.The circuit medium produces enough pressure by the effect of small impeller in the bearing housing, on the one hand forward and backward bearing is lubricated, and magnetic cylinder and separation sleeve annular space in flowing through again on the other hand, internally magnetic cylinder and separation sleeve play cooling action.

Embodiment
With reference to Fig. 1, a kind of anti-magnetic drive pump of finding time comprises the pump housing 4, casing ring assembly 2, bearing housing 6, cooling tank assembly 13, magnetic driver successively and runs through the rotor assembly 1 etc. of the pump housing, bearing housing, cooling tank assembly.Rotor assembly 1 in the pump housing 4 is provided with impeller 3; Rotor assembly in the bearing box assembly 6 is provided with forward and backward bearing 11,12, is provided with small impeller 7 between the front and back bearings; The aqueous cold plate guard system 5 of cooling tank assembly 13 is provided with the outer ring of front and back bearings 11,12; Magnetic driver comprise interior magnetic cylinder 10, outer magnetic cylinder 8 and be located in separation sleeve 9 between the magnetic cylinder 10, outer magnetic cylinder 8.
When 8 rotations of magnetic cylinder outside the motor drives, rotate synchronously with impeller 3 by magnetic cylinder 10 in the effect drive in magnetic field, thereby reach the purpose of pumping liquid.Front and back bearings 11,12 adopts the graphite sliding bearing with greasy property, by carrying the directly lubricated and cooling of liquid; Interior magnetic cylinder 10 and separation sleeve 9 are also by the medium cooling, and outer magnetic cylinder 19 and separation sleeve 9 are by the cooling of the circulating water in the aqueous cold plate guard system 5.So when pump ran well, forward and backward bearing, inside and outside magnetic cylinder can both obtain well lubricated and cooling, can not exist temperature too high, the phenomenon that bearing, inside and outside magnetic cylinder burn out.When pump depletion, the axial force that the rotation of small impeller 7 produces, promoting the forward thrust dish compresses place, fore bearing medium inlet, in bearing housing, form the dielectric space of a sealing, this space is owing to there is the cooling of water-cooled coil pipe, the externally cooling of magnetic cylinder, separation sleeve of aqueous cold plate guard system itself in addition, medium temperature can sharply not raise, and can not cause burning out of bearing wear and inside and outside magnetic cylinder within a certain period of time.
The anti-magnetic drive pump test stand of finding time of the utility model test situation of finding time: turn on pump turned round under rated flow after half an hour, change flow to the cavitation state, until closing inlet valve fully, under the pump depletion state, the pump running was near 25 minutes, the temperature rise of the pump housing and noise ratio find that pump housing temperature rise and noise are normal during to pump housing temperature rise and noise situations and normal operation.20 ℃ of pump housing initial temperatures, 45 ℃ of maximum temperatures.Test back pump is dismantled that finish and check that the main friction member of this pump and magnetic driver are excellent, illustrate that the anti-pump-down performance of this pump is good.And common magnetic drive pump is under evacuated, and friction pair will be moment heavy wear, scaling loss demagnetization in the magnetic driver 5 minutes.
