Technical Problem

[0002]磁力泵的隔离套(也称为磁力隔离套、磁隔离套)是磁力驱动泵的关键组成部分,通常由磁性材料制成,为了满足特殊的使用环境,同时要保证隔离套自身的使用功能,所以磁力套需要采用磁性材料制成,而为了对抗腐蚀性液体,需要采用耐腐蚀性的PFA塑料材质作为内外衬,减少对隔离套的腐蚀,但是由于隔离套和衬垫采用的是粘胶连接,粘胶在腐蚀性液体中容易被溶解破坏,而高温高压的环境又会造成衬垫脱落,影响使用,而衬垫和隔离套的连接在常规技术中无法避免使用粘胶,因此现如今的磁力泵隔离套仍旧无法满足极端的使用环境

Description

Technical Field

[0001] This utility model relates to the skeleton of a high-temperature resistant isolation sleeve for a magnetic pump. Background Technology

[0002] The isolation sleeve (also known as the magnetic isolation sleeve or magnetic isolation jacket) of a magnetic pump is a key component of the magnetically driven pump. It is usually made of magnetic materials. In order to meet the special operating environment and ensure the functionality of the isolation sleeve itself, the magnetic sleeve needs to be made of magnetic materials. In order to resist corrosive liquids, corrosion-resistant PFA plastic material is required as the inner and outer lining to reduce corrosion of the isolation sleeve. However, since the isolation sleeve and the gasket are connected by adhesive, the adhesive is easily dissolved and destroyed in corrosive liquids, and the high temperature and high pressure environment will cause the gasket to fall off, affecting the use. Since the connection between the gasket and the isolation sleeve cannot avoid the use of adhesive in conventional technology, the current magnetic pump isolation sleeve still cannot meet the requirements of extreme operating environments.

[0003] To ensure the adhesive's seal and achieve one-time inner and outer wrapping, a new isolation sleeve skeleton is needed to achieve one-piece molding. Utility Model Content

[0004] This utility model aims to provide a skeleton for a high-temperature resistant isolation sleeve of a magnetic pump. By connecting the skeleton and the gasket of the isolation sleeve through a structure, a covering and limiting effect is formed, reducing the use of adhesive. When the adhesive fails, the skeleton can still support the gasket, ensuring the use of the isolation sleeve in corrosive environments.

[0005] To solve the above problems, the frame of the high-temperature resistant isolation sleeve for a magnetic pump provided by this utility model adopts the following technical solution: A frame for a high-temperature resistant isolation sleeve for a magnetic pump includes a mounting flange, a main body, and a tail end; the mounting flange is located at one end of the main body and is used to mount the entire isolation sleeve; the main body has a cylindrical shape, with the mounting flange and the tail end connected to its two ends respectively, and is covered by a bushing inside and out; the tail end is located at the other end of the main body, connected to the magnetic pump, and also connected to the bushing. The main body is provided with a covering hole, which penetrates the outer wall of the main body and connects the inside and outside of the main body.

[0006] Furthermore, both the mounting flange and the tail end are provided with mounting grooves, which are dovetail grooves that mate with the bushing.

[0007] Furthermore, multiple mounting slots are provided, arranged in a ring on the mounting flange.

[0008] Furthermore, the mounting flange surface is provided with a recessed platform for supporting the bushing, and a mounting groove is also provided on the vertical side wall of the recessed platform.

[0009] Furthermore, a connecting platform is provided on the tail end, one side of which is connected to the end of the main body and extends towards the center. The diameter of the tail end is smaller than that of the main body.

[0010] Furthermore, a covering hole is provided at the tail end and on the connecting platform, which is the same as the covering hole of the main body and extends through the tail end and the connecting platform.

[0011] Furthermore, the covering holes are provided in multiple quantities and arranged in an array on the main body and the tail end.

[0012] Furthermore, the tail end is provided with a central hole that extends axially through the tail end and is sealed by the connector between the outer liner and the inner liner.

[0013] The beneficial effects of this utility model are as follows: The skeleton of the high-temperature resistant isolation sleeve for magnetic pump provided by this utility model can not only meet the magnetic requirements of the isolation sleeve through the skeleton and the liner, but also ensure the corrosion resistance of the isolation sleeve in the high temperature and high pressure environment. It has higher strength and better stability than the isolation sleeve made of pure plastic material, and can achieve durable operation in extreme environments, reducing the maintenance costs of enterprises.
