Embodiment Construction
[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] figure 1 , figure 2 , including cover body 1, bolt hole 2, fillet 3, etc.
[0013] like figure 2 As shown, the present invention is a mechanical gland of a centrifugal pump, which includes a cover body 1 and a plurality of bolt holes 2 evenly distributed on the cover body 1 .
[0014] The cover body 1 is square; the four corners of the square cover body 1 are all rounded corners 3 .
[0015] There are four bolt holes 2, which are respectively located on the four corners of the square cover body 1. The bolt holes 2 are grooves with an open round bottom; the axis of the groove with a round bottom is coincident with the diagonal of the square cover 1 .
[0016] The bolt hole 2 and the cover body 1 in the present invention are cast integrally.
[0017] The cover body 1 in the present invention is square, which can save material co...

The invention relates to a mechanical seal gland of a centrifugal pump. The mechanical seal gland comprises a quadrate cover body, and a plurality of bolt holes uniformly distributed on the quadrate cover body, wherein the quantity of the bolt holes is four, and the four bolt holes are respectively formed on four corners of the quadrate cover body; the bolt holes are in the shapes of opened grooves with round bottoms; and the bolt holes and the cover plate are integrally casted and formed. According to the mechanical seal gland of the centrifugal pump, the cover body is quadrate, so that the materials of the cover body are fewer than those of a circular-plate-shaped cover plate; the bolt holes and the cover body are integrally casted and formed, the bolt holes can be directly casted without being processed, and only the cover body is processed, so that the processes can be saved, and the processing cost can be reduced; and the bolt holes are in the shapes of the opened grooves with the round bottoms, so that the mechanical seal gland can be conveniently adjusted and mounted.
Description
technical field [0001] The invention relates to a centrifugal pump, in particular to a mechanical gland of a centrifugal pump. Background technique [0002] Horizontal single-stage centrifugal pump, including pump body, impeller, pump cover, mechanical seal gland, suspension and shaft, the pump cover is fixed on one side of the pump body, and the pump cavity for installing the impeller is formed between the pump cover and the pump body. The suspension is fixed on one side of the pump cover, the shaft is supported in the suspension by bearings and one end of the shaft extends into the pump chamber, the impeller is arranged in the pump chamber of the pump body and fixed at the end of the shaft, the distance between the pump cover and the shaft There is a mechanical seal chamber for installing a mechanical seal in between, and a mechanical seal gland for positioning the mechanical seal is installed on the outside of the pump cover. [0003] like figure 1 As shown, the existin...
