Abstract
本发明涉及一种双密封结合盘管冷却结构的热水循环泵悬架体，由悬架体、轴套、泵主轴、导轴承、盘管、填料密封体组成，热水循环泵在工作时，悬架体将温度较高的叶轮运行区域与机械密封及轴承工作区域分隔开，高温介质通过悬架体传输的大部分热量可以通过散热翅片与外界环境进行热交换，盘管起到冷却泵轴的作用，填料密封起到减少泄露和隔热的作用，这样高温介质传递给机械密封的热量就不足以对密封寿命产生影响。本发明可以用于对现有的热水循环泵进行改造，从而实现热水循环泵的高效安全工作。
The invention relates to a suspension body of a hot water circulation pump with double seals combined with a coil cooling structure, which is composed of a suspension body, a shaft sleeve, a pump main shaft, a guide bearing, a coil pipe, and a packing sealing body. When the hot water circulation pump is working , the suspension body separates the high-temperature impeller operating area from the mechanical seal and bearing work area, and most of the heat transmitted by the high-temperature medium through the suspension body can exchange heat with the external environment through the cooling fins, and the coil plays a role The pump shaft is cooled, and the packing seal plays the role of reducing leakage and heat insulation, so that the heat transferred from the high-temperature medium to the mechanical seal is not enough to affect the life of the seal. The invention can be used to transform the existing hot water circulation pump, so as to realize efficient and safe operation of the hot water circulation pump.
Description
Technical field
The invention belongs to field of fluid machinery, relate to a kind of cooling unit, particularly a kind of hot water circulating pump suspension body being applied to conveying High Temperature High Pressure hot water or liquid medium, is applied to the industries such as chemical industry, electric power, metallurgy.
Background technique
Hot water circuit can need to use water pump for system in the fields such as chemical industry, electric power, metallurgy, residual heat and energy in pipeline or loop.
Ordinary cycle pump does not have cooling unit, and its mechanical seal and bearing cannot bear high temperature media and damage, and ordinary cycle pump cannot meet the service condition of conveying high-temp liquid system at all, and therefore hot water circulating pump has had good application prospect.
What current use was more is adopt water-cooled hot water circulating pump, this pump utilizes the circulation of cooling water to isolate the temperature of fed sheet of a media, mechanical seal and bearing is avoided to be subject to the impact of high temperature, recycle pump is made to keep stable operation, but on bearing support, cast a cavity time this structure not only will be cast, and cooling chamber gland will be provided with at the opening of cavity.Be exactly in addition, if cooling chamber defective words when casting also easily occurring the situation that sand holes etc. are leaked, also existing and causing the potential problems such as bearing grease chamber water inlet because of casting defect, and then causing mechanical seal and bearing at high temperature to run, cause end wear, produce leakage problem.In addition, as the suspension body of rotor supports built with bearing, there is above-mentioned cooling problem equally.
Summary of the invention
The object of the invention is to ensure that hot water circulating pump runs steadily in the long term, strengthen radiating effect, improve operational safety and the working life of guide bearing, avoid because cooling water is not enough and cause pump operation accident, avoiding the problem because casting defect causes bearing grease chamber to intake simultaneously.
The hot water circulating pump suspension body of coil pipe cooling structure of the present invention, comprises suspension body 1, axle sleeve 2, main shaft 3, guide bearing 4, coil pipe 5, radiating fin 6, stuffing box packing 7; Main shaft 3 is through the through hole in suspension body 1, axle sleeve 2 is equipped with in one end that main shaft 1 passes through hole, guide bearing 4 is arranged between axle sleeve 2 and suspension body 1, main shaft 1 passes between the other end of through hole and suspension body 1 and is provided with stuffing box packing 7, coil pipe 5 is arranged on main shaft 1 periphery wall, and the periphery wall of suspension body 1 is also provided with radiating fin 6.
The hot water circulating pump suspension body of above-mentioned coil pipe cooling structure, described coil pipe 5 is made up of metallic material, and the external diameter of coil pipe 5 is 12mm, and wall thickness is 1mm.
The hot water circulating pump suspension body of above-mentioned coil pipe cooling structure, described radiating fin 6 arranges 4, is evenly arranged along suspension body 1 periphery wall circumference, radiating fin 6 thickness 4mm, high 45mm.
The hot water circulating pump suspension body of above-mentioned coil pipe cooling structure, also comprises O type circle shock reducing structure, and described O type circle shock reducing structure is arranged between guide bearing 4 and suspension body 1.
When hot water circuit pump operation, suspension body is static, pump main shaft High Rotation Speed, and suspension body left-hand component is directly connected with the pump cover of hot water circulating pump, right-hand component connection bearing case and mechanical sealing base.
Device tool of the present invention has the following advantages: the cooling structure of traditional hot water circulating pump, if easily there is the situation that sand holes etc. are leaked in cooling chamber defective words when casting, simultaneously traditional structure normally works in order to the sealing and bearing ensureing pump, need to utilize a large amount of cooling water by the pump housing higher for chilling temperature, cause sealing case bearing to avoid heat by intermediate support conduction.The present invention changes the complexity cooling cavity that former hot water circulating pump adopts, and by being wound around coil pipe at pump main shaft, enhances the radiating effect to main shaft, compare original type of cooling, greatly reduce cooling water amount, saved operating cost, avoid because cooling water is not enough and cause pump operation accident.In addition, the periphery wall of suspension body is also provided with 4 radiating fins, significantly enhances the convection heat exchange effect of suspension body and air, solve the problem that hot water circuit pump mechanical sealing and bearing cannot bear high temperature media and damage well.Moreover the effect of protection guide bearing is played in the application of O type circle shock reducing structure, achieves the operation of hot water circulating pump long-term stability.
