Abstract

The utility model belongs to a pump, more exactly a self-suction type rotor pump, which is applicable to transmit high viscosity medium and low viscosity medium in the petroleum and chemical engineering field. The utility model has the advantages of small size, simple structure, low noise, and stable running. The self-suction type rotor pump is composed of an eccentric pump body, an end cover, a spacing ring, a main shaft, a rotor lead frame, a sliding blade assembly, a sealing gland, an external bearing frame, a bearing gland, bearings, etc. The main shaft is arranged in the eccentric pump body via the rotor, the lead frame, the sealing gland, and the bearings, and the sealing gland is buckled on a sealing ring and forms a tight fit with the lateral face of the end cover. The spacing ring is sheathed on the end cover and forms a sliding fit with the end cover. The lead frame is inlaid on the rotor, and both ends of the sliding blade assembly are fitted with the lead frame.

Description

Self-priming rotor pump

The utility model belongs to pump, more precisely is a kind of self-priming rotor pump, is applicable to that oil, chemical field transmit high and low viscosity medium.

Pump of a great variety, structure is different, and wherein centrifugal pump uses extensively, and the centrifugal pump volume is bigger, the component processed complex, amount of maintenance is big.Displacement pump efficient is higher, and flow is accurate, has preferably from absorption, uses extensively, and the rational displacement pump of development structure has broad application prospect.

Given this purpose of this utility model is to provide a kind of high performance self-priming rotor pump, and it is little, simple in structure that this pump has a volume, and installation and maintenance are convenient, and noise is low, operates steadily, and the characteristics that efficient is high are suitable for transmitting all kinds of flowing mediums.

The purpose of this utility model is achieved through the following technical solutions: self-priming rotor pump is by the eccentric pump housing, end cap, limited ring, main shaft, rotor helical pitch frame, slide plate assembly, sealing gland, the outboard bearing frame, bearing gland, compositions such as bearing, wherein bearing means is in external bearing bracket stand, bearing gland is solid on external bearing bracket stand by the button that is threaded, and main shaft is by rotor, helical pitch frame, sealing gland, bearing, device is in the eccentric pump housing, and sealing gland buckles on seal ring, with end cap side drive fit, limited ring is nested with on end cap, is slidingly matched with end cap, and helical pitch frame edge is enclosed within on the rotor, constitute rotor assembly, slide plate assembly two ends cooperate with the helical pitch frame, and the spindle nose of slide plate assembly cooperates with the shrinkage pool of limited ring, and the groove of slide plate assembly is built-in with spring, the wear compensation bar falls to putting in groove and cooperates with spring, by bolt with the outboard bearing frame, end cap, the eccentric pump housing connects as one.

In conjunction with the accompanying drawings concrete structure of the present utility model is described further.

Fig. 5 is the utility model limited ring structure sectional view.

Fig. 6 is the utility model slide plate assembly structure chart.

Fig. 7 is the utility model slide plate assembly structure sectional view.

With reference to Fig. 1-7, self-priming rotor pump is by the eccentric pump housing 8, end cap 4, limited ring 5, main shaft 9, rotor helical pitch frame 7, slide plate assembly 6, sealing gland 3, outboard bearing frame 2, bearing gland 1, bearing 11 compositions such as grade, its middle (center) bearing 11 devices are in external bearing bracket stand 2, and bearing gland 1 is solid on external bearing bracket stand 2 by the button that is threaded, main shaft is by rotor 10, helical pitch frame 7, sealing gland 3, bearing 11, device is in the eccentric pump housing 8, sealing gland 3 buckles on seal ring 12, and with end cap side drive fit, limited ring 5 is nested with on end cap 4, be slidingly matched with end cap 4, helical pitch frame 7 edges are enclosed within on the rotor 10, constitute rotor assembly, and slide plate assembly 6 two ends cooperate with helical pitch frame 7, the spindle nose 15 of slide plate assembly 6 cooperates with the shrinkage pool 16 of limited ring 5, the groove of slide plate assembly 6 is built-in with spring 14, and wear compensation bar 13 falls to putting in groove and cooperates with spring 14, by bolt 17 with outboard bearing frame 3, end cap 4, the eccentric pump housing 8 connects as one.

In the utility model, by rotor assembly, slide plate assembly and pump housing inner chamber form some Seal cages, rotor assembly rotates by main shaft, and each Seal cage produces volume-variation in rotation process, realizes the suction of medium, because slide plate assembly two spindle noses are packed in the limited ring, mushroom in the slide plate assembly is wiped the compensation bar and pump housing inner chamber is the bearing operation state in rotation process, helps reducing rotating friction, improves the complete machine operational efficiency.
