Abstract
The utility model discloses a main shaft sliding bearing of a magnetic pump, which is characterized in that the main shaft sliding bearing on a sliding bearing block of a pump cover is formed by combining a sliding bearing made of a graphite material and a sliding bearing made of a silicon carbide material so as to form a combined sliding bearing. Due to the impact resistance of graphite and the abrasions resistance of silicon carbide, the impact resistance and the service life of the whole sliding bearing are improved, particularly, the using safety and reliability of the sliding bearing are improved.
Description
Technical field
the utility model relates to the sliding bearing structure form of magnetic drive pump, particularly magnetic drive pump main shaft.
Background technique
The main shaft of
magnetic drive pump is rotatably assorted through sliding bearing with pump cover and is connected; The sliding bearing of existing technology magnetic drive pump main shaft is the single material material of integrated type; Because sliding bearing belongs to easily damaged parts; Magnetic drive pump is in operation process, and factors such as the uneven perhaps peripheral passage obstruction of the axial force of pump shaft cause sliding bearing to damage easily, cause the parking of magnetic drive pump; Therefore the fragment of sliding bearing also possibly cause the scuffing of magnetic drive pump inner piece, and it is very big the use of magnetic drive pump and user to be produced influence.
The model utility content
novel purpose of this use is to improve to the shortcoming deficiency of above-mentioned existing technology, provides a kind of usability good, long service life, the magnetic drive pump main shaft sliding bearing mechanism that Security is good.
in view of this consideration; The utility model improves the structural type of magnetic drive pump main shaft sliding bearing, and the sliding bearing of former single material is changed into by graphite material sliding bearing and two combined type sliding bearings of forming side by side of carbofrax material sliding bearing.
the utility model magnetic drive pump main shaft sliding bearing adopts two sections fabricated structures arranged side by side, and the main shaft sliding bearing that promptly is installed on the pump cover plain bearing housing is constituted by one section graphite material sliding bearing 1 and one section carbofrax material sliding bearing 2 side by side.
the utility model is rational in infrastructure, is constituted side by side by graphite material and silicon carbide material, and the graphite material shock resistance is good; Be not easy to pulverize; But wear resistance is poor than silicon carbide, and the silicon carbide material wear resistance is good, but impact resistance is poor than graphite; Adopt these two kinds of material structures to be combined into sliding bearing side by side, utilized the advantage of wear resistance of impact resistance, the silicon carbide of graphite, make whole sliding bearing impact resistance and being improved working life; The safety and reliability of sliding bearing have particularly been improved, when factors such as axial force imbalances, when causing sliding bearing silicon carbide partly to damage; The graphite bearing of sliding bearing is according to playing a role; The rotor system of pump can guarantee to be in concentric equally, and holding pump runs well, and plays the effect of second protection; Rotor can not occur and be ground to separation sleeve, the serious accident that causes pump to leak takes place.Need in the time of can preventing to damage stop to magnetic drive pump immediately, is provided the sufficient reaction time, take corresponding measure, the influence of the reduction of minimum producing to production work because of Magnetic Drive Pump Sliding Bearing.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
the utility model magnetic drive pump main shaft sliding bearing is installed on the plain bearing housing 3 of pump cover; The main shaft sliding bearing is constituted by one section graphite material sliding bearing 1 and one section carbofrax material sliding bearing 2 side by side, forms the combined type sliding bearing.Corresponding graphite material sliding bearing 1 is provided with sliding bearing expanding ring 10,20 with carbofrax material sliding bearing 2 on plain bearing housing 3, be that a side of graphite material sliding bearing 1 or carbofrax material sliding bearing 2 is provided with flexible buffer pad 4 on plain bearing housing 3 stopping tables.
Claims (1)
1. magnetic drive pump main shaft sliding bearing, the main shaft sliding bearing that it is characterized in that being installed on the pump cover plain bearing housing is constituted by one section graphite material sliding bearing (1) and one section carbofrax material sliding bearing (2) side by side, forms the combined type sliding bearing.
