Abstract
The utility model discloses a kind of internal messing water pump, comprise the pump housing (1), ring gear (2) and the pump shaft (4) with gear (3) is provided with in the described pump housing (1), between described ring gear (2) and gear (3), be provided with crescent (5) and diaphragm seal (6), the inwall of the inner chamber of the described pump housing (1) is provided with one deck wearing layer (7).The utility model has simple, the easily manufactured advantage of structure, owing to have employed wearing layer, when water pump carries out work, makes pump housing inwall, crescent inwall and diaphragm seal outer wall have stronger wear resistance, greatly reduces wearing and tearing, extend working life.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of internal messing water pump.
Background technique
Existing water pump, be generally centrifugal pump, although general pump water operation can be carried out, it is large to there is volume in centrifugal pump, inefficient problem, can only reach the power of about 40%, simultaneously, the self-priming of centrifugal pump can be poor, make its lift lower, can only reach about 40 meters, using scope has narrow limitation.And existing gear pump, as long as the operation of pump oil, if for the operation of pump water, because the viscosity of water is lower than oil viscosity, ring gear is in floating state, when for pump oil, can form oil film, and during pump water, just cannot form moisture film, cause wearing and tearing comparatively serious, working life is extremely short.
Model utility content
The purpose of this utility model is just to provide a kind of internal messing water pump of long service life.
The purpose of this utility model is realized by such technological scheme, a kind of internal messing water pump, comprise the pump housing, ring gear and the cogged pump shaft of band is provided with in the described pump housing, between described ring gear and gear, be provided with crescent and diaphragm seal, the inwall of the inner chamber of the described pump housing is provided with one deck wearing layer.
In order to simple process, between the inwall and wearing layer of the described pump housing, be provided with adhesive-layer.
In order to improve wear resistance, at the inwall of described crescent and with Gear Contact Surface on be provided with wearing layer; The outer wall of described diaphragm seal is provided with wearing layer.
Owing to have employed technique scheme, the utility model has simple, the easily manufactured advantage of structure, owing to have employed wearing layer, when water pump carries out work, pump housing inwall, crescent inwall and diaphragm seal outer wall is made to have stronger wear resistance, greatly reduce wearing and tearing, extend working life.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of internal messing water pump, comprise the pump housing 1, ring gear 2 and the pump shaft 4 with gear 3 is provided with in the described pump housing 1, between described ring gear 2 and gear 3, be provided with crescent 5 and diaphragm seal 6, the inwall of the inner chamber of the described pump housing 1 is provided with one deck wearing layer 7.
Easy in order to technique, facilitates the setting of wearing layer 7, between the inwall and wearing layer 7 of the described pump housing 1, is provided with adhesive-layer 8.
In order to improve the abrasion resistance of crescent 5 and diaphragm seal 6, increase the service life, at the inwall of described crescent 5 and with gear 3 surface of contact on be provided with wearing layer 7, the outer wall of described diaphragm seal 6 is provided with wearing layer 7.
