Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

Examples

This embodiment pump cover comprises two parts, can fix the fixed external member 1 of pump body outer wall promptly and be used for sealing action's sealing member 2, utilizes the cooperation of the two can realize the sealed also more convenient when installation and dismantlement of the pump body, and equipment needs customize special fixed external member 1 and the sealing member 2 that accords with pump body size according to the pump body size not.

As shown in fig. 1-4, a pump cover convenient for disassembly comprises a fixed set 1 and a sealing member 2, the fixed set 1 comprises symmetrically arranged fixed half rings 101, the fixed half rings 101 are fixedly connected with each other through a fixing bolt 102, the bottoms of the outer walls of the two fixed half rings 101 are fixedly connected with fixing plates 104 with holes on the tops, the tops of the outer walls of the two fixed half rings 101 are rotatably connected with a first pressing arm 107 and a second pressing arm 108 through a connecting rotating shaft 106, the bottoms of the first pressing arm 107 and the second pressing arm 108 are fixedly connected with symmetrically arranged pressing blocks 110, the bottoms of the pressing blocks 110 are contacted with the top of the sealing member 2, the first pressing arm 107 is fixedly connected with the fixing plate 104 fixed on the fixed half ring 101 connected with the second pressing arm 108 through a fastening bolt 109, the second pressing arm 108 is fixedly connected with the fixing plate 104 fixed on the fixed half ring 101 connected with the first pressing arm 107 through a fastening bolt 109, the holes on the top of the fixing plate 104 are fixedly connected with a rubber gasket 105, the inner wall of the fixed half ring 101 is fixedly connected with a friction ring 103, and the inner wall of the friction ring 103 is provided with semi-circular grooves at equal intervals.

The pump cover installation position should be known in advance when the fixed installation of the fixed suite 1 is carried out, the well fixing suite 1 is installed on the outer wall of the pump body in a short distance, the pump cover installation is different from the traditional pump cover installation, a bolt hole for installation does not need to be reserved on the pump body for the installation of the equipment, therefore, the well fixing suite 1 can be used for the pump bodies of most specifications and models, in the actual installation, the fixed half ring 101 is firstly fixed on the outer wall of the pump body and locked by using the fixing bolt 102, the sealing element 2 is pre-fixed at the sealing position of the pump body, then, the first pressure arm 107 and the second pressure arm 108 are pressed downwards by using the fastening bolt 109, and the four corners of the well sealing element 2 are pressed by using the pressing block 110, so that the sealing of the pump body is ensured.
