Detailed Description
As described in the background art, the process heat preservation pump is a requirement of market development, medium materials in certain working conditions need to work at constant temperature, the materials are guaranteed to be in a solution state, crystallization and scaling are avoided, and flow channels of a pump body and an impeller are prevented from being blocked, otherwise, the normal operation of the whole system is influenced, and serious influence is brought to other equipment of the system.
The existing flow heat preservation pump is shown in fig. 1, the pump body is formed by casting, the pump body is assembled and welded with a first pump sealing plate 1, a second pump sealing plate 2, a third pump sealing plate 3 and a fourth pump sealing plate 4 and a pump tower 5, the shapes of all parts are irregular, assembly and welding parts are more, the working procedure is complex, and the processing time is long.
Based on this, the inventors created the flow heat preservation pump of the present utility model to solve the above technical problems.
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
Examples
Referring to fig. 2 to 4, a process heat preservation pump includes a pump body 10 and a sleeve 20, the pump body 10 includes an inlet flange 11, a first joint 12 and a second joint 13, a first end of the sleeve 20 is sleeved on and welded to the periphery of the inlet flange 11, and a second end of the sleeve 20 is welded to the outer wall of the pump body 10, so that a closed chamber is formed between the sleeve 20 and the pump body 10. Here, the inlet flange 11 refers to the inlet of the material transported by the process heat pump. The first connector 12 and the second connector 13 are both suitable for being connected with a mechanical seal water pipe, the first connector 12 is communicated with an inlet of a constant temperature water source of the pump body 10, and the second connector 13 is communicated with an outlet of the constant temperature water source of the pump body 10. For example, the medium flowing in the mechanical seal water pipe can be heat preservation steam so as to maintain a basic constant temperature state in the pump body 10, so as to ensure that the material is in a solution state, so that crystallization and scaling are avoided, and even flow channels of a pump body and an impeller are blocked.
