Description
Technical field
The utility model relates to the technical field of structures of water pump.
Background technique
In the fields such as metallurgy, chemical industry, electric power, heating, usually adopt a kind of hot water circulating pump to finish the conveying of hot water or organic heat exchange medium.
Hot water circulating pump has natural circulation and two kinds of forms of pump circulation, and wherein the heat utilization rate of pump circulation form is higher, and the usage requirement of pump also is higher than the natural circulation form.In recent years, the pump circulation form is subject to extensive use, thereby common recycle pump can't satisfy its requirement on serviceability temperature and inlet pressure.
The water-cooled hot water circulating pump has and differs from common recycle pump, it utilizes cooling water to come mechanical seal and the cooling chamber of circulating cooling pump, but this structure need to be arranged corresponding recirculating cooling water system usually at the scene, also there are the potential problems such as external refrigeration water shortage and cooling line obstruction, if cooling water system breaks down, will cause mechanical seal and bearing at high temperature to move, and then produce end wear, cause on-the-spot leakage, the safety of threat personnel and system's operation.In addition, suspension is equipped with a sleeve radial bearing and a pair of back-to-back thrust-bearing, has equally the cooling problem.
Summary of the invention
The purpose of this utility model is the hot water circulating pump suspension body with heat sinking function in order to guarantee that hot water circulating pump moves steadily in the long term under the operating mode that does not adopt extraneous cooling water.
The utility model comprises the suspension body, in the suspension axon to axial hole is set, in described axial hole, place the pump main shaft, the axial hole two ends that it is characterized in that described suspension body are large, the middle part is little, between the axial hole of suspension body one end and suspension body, guide bearing is set, bearing and mechanical seal device are set in the axial hole of the suspension body the other end, described pump main shaft is set in described guide bearing, in mechanical seal device and the bearing, the middle part of pump main shaft is set in the middle part of axial hole, described mechanical seal device is arranged in the inboard of bearing, arrange bearing cap in the outside of described bearing, connect fan at the pump main shaft of the external end of suspension that is provided with bearing cap.
Because above design, hot water circulating pump is when work, separate pump operation local and mechanical seal operation area that the suspension body is higher with temperature, the high temperature media heat that passes to mechanical seal just is not enough to exerting an influence sealing life like this, and the ceramic bearing that suspension body front end is installed has self-lubricating function, can realize selflubricating by the thermal medium of pump body, heat resistant and wear resistant decreases and resistance to chemical attack, so just guaranteed the long-time steady operation of mechanical seal and bearing, can being used for of this structure transforms existing hot water circulating pump, thereby realizes the air cooling of hot water circulating pump.In addition, the utility model has also installed fan additional in suspension body rear end, plays the effect of forced heat radiation, further reduces the heat that is transferred to mechanical seal and bearing by the suspension body.The utility model can guarantee effectively that hot water circulating pump can move steadily in the long term under the operating mode that does not adopt extraneous cooling water, avoid adopting complicated water-cooled structure, simultaneously can using water wisely, avoid the pump operation accident that causes owing to cooling water deficiency or line clogging.
The utility model also arranges radiating fin in the external side of suspension, can play preferably thermolysis, stops the heat of high temperature fluid in the pump housing to transmit mechanical seal and the bearing that send the back.
In addition, in order to ensure the sealing of bearing, the utility model also arranges the spacer ring of sealing in the axial hole of the suspension body of placement of mechanical seal arrangement and bearing, described mechanical seal device and bearing are arranged in the both sides of spacer ring, offer through hole at the suspension body sidewall of placement of mechanical seal arrangement.
In order to make things convenient for the utility model to be connected with the installation of pump case, at the suspension end of body that guide bearing is set the pump case attachment hole is set.
