Abstract
The invention relates to a hot water circulating pump suspension body of a coiler cooling structure. The hot water circulating pump suspension body of the coiler cooling structure is composed of a suspension body, a shaft sleeve, a pump main shaft, a guiding bearing, a coiler and a packing sealing body. When a hot water circulating pump works, an impeller working area with a higher temperature is separated from a mechanical sealing working area and a bearing working area by the suspension body, heat exchanging can be conducted between most heat, transmitted by the suspension body, of high-temperature media and the external environment through by means of cooling fins, the coiler serves as a cooling pump shaft, the packing sealing body can reduce leakage and insulate heat, and therefore the heat transmitted to mechanical sealing by the high-temperature media can not influence the sealing life. The hot water circulating pump suspension body of the coiler cooling structure is used for transformation of an existing hot water circulating pump, and efficient and safe working of the hot water circulating pump is achieved.
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 that is applied to carry High Temperature High Pressure hot water or liquid medium, is applied to the industries such as chemical industry, electric power, metallurgy.
Background technique
In the fields such as chemical industry, electric power, metallurgy, residual heat and energy, can need to use water pump to be used for the hot water circuit in system 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 carrying high-temp liquid system at all, so hot water circulating pump has had good application prospect.
What use was more at present is to 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, avoid mechanical seal and bearing to be subject to the impact of high temperature, make recycle pump can keep stable operation, but when this structure not only will be cast, on bearing support, cast a cavity, and will be provided with at the opening of cavity cooling chamber gland.Be exactly in addition, if cooling chamber when casting defective words also easily there is the situation that sand holes etc. are leaked, also exist because of casting defect, to cause the potential problems such as bearing grease chamber water inlet, and then cause mechanical seal and bearing at high temperature to move, cause end wear, produce leakage problem.In addition, in the suspension body as rotor supports, bearing is housed, has equally above-mentioned cooling problem.
Summary of the invention
The object of the invention is in order to guarantee that hot water circulating pump moves steadily in the long term, strengthen radiating effect, improve operational safety and the working life of guide bearing, avoid causing pump operation accident because cooling water is not enough, avoid causing because of casting defect the problem of bearing grease chamber water inlet 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 on suspension body 1, main shaft 1 passes on one end of through hole axle sleeve 2 is housed, 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, is also provided with radiating fin 6 on the periphery wall of suspension body 1.
The hot water circulating pump suspension body of above-mentioned coil pipe cooling structure, described coil pipe 5 is made by 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 circumferentially evenly arranged radiating fin 6 thickness 4mm, high 45mm along suspension body 1 periphery wall.
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.
In the time of 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 cooling chamber when casting defective words easily there is the situation that sand holes etc. are leaked, traditional structure is normally worked in order to guarantee sealing and the bearing of pump simultaneously, need to utilize a large amount of cooling waters by the higher pump housing of chilling temperature, to avoid heat to conduct and cause sealing case bearing by intermediate support.The present invention changes the cooling cavity of complexity that former hot water circulating pump adopts, and by being wound around coil pipe at pump main shaft, has strengthened the radiating effect to main shaft, compare original type of cooling, greatly reduce cooling water amount, saved operating cost, avoided causing because cooling water is not enough pump operation accident.In addition, on the periphery wall of suspension body, be also provided with 4 radiating fins, greatly strengthened the convection heat exchange effect of suspension body and air, solved well that hot water circuit pump mechanical sealing and bearing cannot bear high temperature media and the problem damaged.Moreover the effect of protection guide bearing is played in the application of O type circle shock reducing structure, has realized the operation of hot water circulating pump long-term stability.
