Abstract
The utility model relates to an axially split pump and particularly relates to an axially split pump for a general-purpose pump shaft. The axially split pump comprises a pump body, an impeller, a sealing ring, a round nut, a shaft shoulder retaining ring, a water retaining ring, a shaft sleeve nut, a packing gland, a pump cover and a coupler. The pump is characterized in that the pump cover and the packing gland are connected through a bolt and a nut, one end of the pump shaft is fixed axially through the shaft shoulder retaining ring, the other end of the pump shaft is connected with the coupler, two ends of the pump shaft are respectively assembled inside a bearing of a bearing body and are connected fixedly through the round nut, the water retaining ring, the shaft sleeve nut and the impeller are arranged on the pump shaft, and the sealing ring is connected with the pump shaft in a sleeving mode. The axially split pump for the general-purpose pump shaft is impact in structure and convenient to maintain and repair.
Description
Technical field
The utility model relates to a kind of middle-opening pump, is exactly specifically to be used for general pump shaft middle-opening pump.
Background technique
In the various middle-opening pump models of domestic production at present, the generalization degree of its pump shaft is very low, and what specifications are basically has the how many kinds of pump shaft is just arranged; Because the more so difficult tissue production of type of axle; Cause quantity in stock bigger easily, the occupation of capital is more, and it is higher to make cost of production.
Summary of the invention
The utility model is poor for the matching that solves between existing pump shaft and the middle-opening pump, in case the not problem of easy care that breaks down, the technological scheme of employing is: a kind of middle-opening pump; Comprise the pump housing, impeller, seal ring, round nut, retaining ring for shaft shoulder, water retaining ring, sleeve nut, Gland, pump cover, coupling; It is characterized in that: pump cover is connected through bolt and nut with Gland, and pump shaft carries out axial restraint through retaining ring for shaft shoulder, and the other end of pump shaft is connected with coupling; The two ends of pump shaft are assemblied in respectively in the bearing of bearing support; Be fixedly connected through round nut, pump shaft is provided with water retaining ring, sleeve nut and impeller, and is socketed with seal ring.
The utility model has mainly been made suitable adjustment to the pump structure of models such as 150S100; And according to the match power size of various pump pump shaft has been carried out optimal design, the structure decrease of this series pump the kind of pump shaft kind nearly 1/2 nearly 2/3, bearing support improved the generalization degree of these series product.
Because the kind of axle and bearing support has reduced; Part specification on the bearing of corresponding series pump and the axle has also reduced; Organization of production and storage keeping, the corresponding reduction of operating cost and sales expense, the corresponding raising of economic benefit and social benefit have been made things convenient for greatly.The utility model structure is compact more, maintains convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
A kind of general pump shaft middle-opening pump 1; Pump cover 12 and Gland 11 are connected through bolt and nut, and pump shaft 6 carries out axial restraint through retaining ring for shaft shoulder 8, and the other end of pump shaft 4 is connected with coupling 13; The two ends of pump shaft 4 are assemblied in respectively in the bearing of bearing support 5; Be fixedly connected through round nut 7, water retaining ring 9, sleeve nut 10 and impeller 2 be installed on the pump shaft, and be socketed with seal ring 3.
