Abstract
The present invention relates to a novel thermal structure of mechanically sealed non-normal temperature chemical flow pump including: a pump shaft, a shaft sleeve, a mechanically sealed chamber, a pump cover, a pump body. The structure is characterized in that: the hollow pipe including the heat preservation agent is connected to the mechanically sealed chamber through a hole on the pump body, and the hollow pipe which is around the shaft sleeve in the mechanically sealed chamber extends out the pump body through the hole on the pump body to connect with a circular pump. The advantage of the structure is: the heat preservation effect being improved, taking full advantage of the space, and dispensing with a heat-preservation chamber which occupies a lot of space.
Description
Technical field
The utility model relates to a kind of insulating structure, particularly a kind of non-normal temperature chemical flow-process pump mechanical seal novel heat insulation structure.
Background technique
Chemical flow-process pump is applied to some low temperature and high temperature occasion through regular meeting; for the working life that increases pump and the Security of application; the liquid of meeting external cooling on the pump housing or pump cover usually (or insulation) is to reach the use that makes pump temperature unlikely too high (or low excessively) and influence pump.Pump key position just is mechanical seal place so, sealing because effect of itself and structure to be doomed be an easily damaged parts, cooling (or insulation) chamber all to be set during high temperature (or low temperature) usually outside Seal cage, to increase life-span and the reliability that seals.Its shortcoming just is that cooling (or insulation) the common spatial volume in chamber of outside is very big, still to connect cooling tube simultaneously, and, so both waste the space owing to the reason heat-transfer effect of pump cover wall thickness is bad, with regard to expensive chemical pump, also more wasted material for original material.
Summary of the invention
The purpose of this utility model is that mechanical seal place that solves chemical flow-process pump in the prior art is provided with cooling (or insulation) existing the problems referred to above in chamber, and a kind of non-normal temperature chemical flow-process pump mechanical seal novel heat insulation structure is provided.The utility model designs non-normal temperature chemical flow-process pump mechanical seal novel heat insulation structure, comprise pump shaft, axle sleeve, mechanical seal chamber, pump cover, the pump housing, it is characterized in that: the hollow tube that will be connected with heat preserving agent is inserted in the mechanical seal chamber by the through hole on the pump housing, hollow tube is around the axle sleeve that is positioned at the mechanical seal chamber, and hollow tube stretches out the pump housing by the through hole on the pump housing again and connects recycle pump.The utility model has the advantages that the enhancing heat insulation effect, made full use of the space, save the very large incubation cavity of volume.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise pump shaft 1, axle sleeve 2, mechanical seal chamber 3, pump cover 4, the pump housing 5 among the figure, it is characterized in that: the hollow tube 6 that will be connected with heat preserving agent is inserted in the mechanical seal chamber 3 by the through hole on the pump housing 57, hollow tube 6 is around the axle sleeve 2 that is positioned at mechanical seal chamber 3, and hollow tube 6 stretches out the pump housing 5 by the through hole on the pump housing 58 again and connects recycle pump.Incubation cavity on the common pump postoperculum is removed, and take thermal insulation pipe is directly fed in the mechanical seal chamber, and take the mode of coil pipe type, to strengthen heat insulation effect around whole axle sleeve 2.Do the material that to save pump cover 4 greatly like this, be positioned at before the mechanical seal owing to thermal insulation pipe simultaneously, and directly contact,, also can not influence other structural change, made full use of the space so can strengthen heat preservation effect with medium.
