Abstract
A kind of sweat oil pump of tool heat preservation cylinder, including the pump housing, middle section shell, heat-insulated cylinder, middle section outer cover suit both ends are equipped with the heat-insulated cylinder of annular convex platform, and heat-insulated cylinder is set with steel pipe, and steel pipe both ends and heat-insulated cylinder both ends boss seam allowance position, closed heat-insulated cavity is set between heat-insulated cylinder and steel pipe, annular partition is set in heat-insulated cavity.The heat insulation cylinder body of the utility model can change the influence of the external boundary's heat radiation of high temperature wax oil; wax oil leaks into atmosphere when high temperature and pressure being avoided to run; the personnel around pumping unit and equipment instrument are protected, greatly improves the safety of equipment, stability and to extraneous environmental protection；During pump is stopped using, the insulating layer between heat-insulated cylinder and doughnut-shaped steel plate effectively can carry out isothermal holding to the medium inside equipment, prevent from solidifying after pumping interior medium temperature reduction, pump is caused to be unable to operate normally.
Description
Technical field
The utility model relates to industrial pump technical fields, are specifically related to a kind of sweat oil pump of tool heat preservation cylinder.
Background technique
With the development of oil refining factory, centrifugal multistage pump multiple centrifugal pump has in multiple fields such as petroleum, petrochemical industry, chemical industry is widely answered
With.It is not that be directed to high temperature, high pressure wax oil operating condition requirement individually designed since existing chemical flow-process pump is general-purpose pump
Production, and wax oil itself has particularity, demand pressure is big, and the operation and parking to pump have particular/special requirement, often exists
Pump body generates solidification phenomenon when parking, can not operate normally, or even power of motor can be caused to overload, causes motor damage.
Further, since such pump needs to keep higher temperature to ensure that wax oil low viscosity is run in the process of running, lead to existing stone
Sweat oil that oiling factory uses pump use temperature high, and pump case temperature can be made to generate 300 DEG C or so of high temperature, general multistage from
Heart pump is unable to satisfy this industrial and mineral requirement, therefore needs to improve in structure and design, is wanted with meeting the use of sweat oil pump
It asks.
Summary of the invention
To make up for the shortcomings of the above existing technologies, the purpose of the utility model is to provide under a kind of wax of tool heat preservation cylinder
Oil pump changes the influence of the external boundary's heat radiation of high temperature wax oil, avoids jeopardizing the personnel around pumping unit when high temperature, high-voltage operation
And equipment instrument etc., greatly improve safety, the stability of equipment.
The utility model is achieved through the following technical solutions, a kind of sweat oil pump of tool heat preservation cylinder, including the pump housing,
Middle section shell, heat-insulated cylinder, it is characterized in that：Middle section outer cover suit both ends are equipped with the heat-insulated cylinder of annular convex platform, heat-insulated barrel jacket
Steel loading pipe, steel pipe both ends and heat-insulated cylinder both ends boss seam allowance position, and closed incubation cavity is arranged between heat-insulated cylinder and steel pipe
Body, heat-insulated cavity is interior to be arranged annular partition.
The utility model has the advantages that：Heat insulation cylinder body can change the influence of the external boundary's heat radiation of high temperature wax oil, avoid height
Wax oil leaks into atmosphere when warm high-voltage operation, protects the personnel around pumping unit and equipment instrument, greatly improves equipment
Safety, stability and to extraneous environmental protection；During pump is stopped using, the insulating layer between heat-insulated cylinder and doughnut-shaped steel plate can
Effectively to carry out isothermal holding to the medium inside equipment, prevents from solidifying after pumping interior medium temperature reduction, cause pump can not be just
Often operation.
Detailed description of the invention
Fig. 1 is the structure schematic diagram of the utility model.
In Fig. 1：Heat-insulated cylinder 1, heat-insulated cavity 2, steel pipe 3, annular partition 4, middle section 5, middle section shell 6, the pump housing 7, boss
8。
Utility model is described in further detail by example below in conjunction with attached drawing, but following examples is only this
Utility model example therein does not represent rights protection scope defined by the utility model, the power of the utility model
Sharp protection scope is subject to claim.
Specific embodiment
Seeing Fig. 1, the specific structure of the utility model is：The middle section shell 6 of the pump housing 7 be set with both ends be equipped with annular convex platform every
Hot cylinder 1, two semi-circular sheet steels of seam allowance localization criteria specification on the boss 8 at heat-insulated 1 both ends of cylinder, by two semicircle steel
Closed steel pipe 3 is made in plate welding, guarantees welding quality, sealed thermal insulating chamber between heat-insulated cylinder 1 and steel pipe 3 by hydrostatic test
Annular partition 4 is set in body 2.
The working principle of the utility model：Isolation level is carried out by first layer middle section 5 when the pump operation and grade is excessive, institute
Stating heat-insulated cylinder 1 is the second layer, is thermally shielded and protects to liquid, and heat-insulated cavity 2 and steel pipe 3 form third layer, to medium
With insulation effect.
