Abstract
The utility model discloses a high-temperature pump, which comprises a pump cavity, a mechanical sealing cavity and a bearing cavity, wherein the mechanical sealing cavity is separated from the pump cavity, a cooling jacket is arranged outside the mechanical sealing cavity, a rapid cooling cavity is arranged on one side of the mechanical sealing cavity and filled with rapid cooling liquid, a rapid cooling liquid inlet and a rapid cooling liquid outlet are respectively formed in the rapid cooling cavity, and the rapid cooling liquid flows into the rapid cooling cavity from the rapid cooling liquid inlet and flows out through the rapid cooling liquid outlet. Due to the arrangement, the working temperature of mechanical seal is greatly reduced, and the effective protection to various conditions during the sealing failure is carried out by taking multiple safeguard measures. The high-temperature pump is suitable for delivering various high-temperature media.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of high temperature pump.
Background technique
High temperature pump is the very extensive equipment of a kind of use that is used for carrying high temperature media in the present various industrial production.Existing high temperature pump, because the defective on its structural design, make it exist some shortcomings aborning: its Seal cage and pump chamber are adjacent, the heat of high temperature media is easy to be passed to Seal cage in the pump chamber, make Seal cage be in the condition of high temperature, sealing material can produce thermal expansion, and different materials thermal expansion difference, therefore can produce leakage-gap, reduce sealing effect.When sealing goes wrong, leakage fluid can leak to bearing bore along pump shaft, and leakage fluid enters bearing bore can cause that bearing lubrication lost efficacy; The sealing surface of machine envelope is owing to be in high temperature, and the oil that is transferred is easily charing at high temperature, can form carbon granule after the charing, attached to sealing surface, can cause seal failure; Behind the pump operation certain hour, may produce gas and foreign matter in the mechanical seal chamber, if gas and foreign matters are discharged, then can cause mechanical seal to be lost efficacy.
The model utility content
For solving the aforementioned problems in the prior, the utility model proposes a kind of new type high temperature pump structure, may and overcome its issuable damage in back of losing efficacy with what reduction mechanical seal was lost efficacy.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
A kind of high temperature pump comprises pump chamber, mechanical seal chamber, bearing bore, and described pump chamber and mechanical seal chamber are separated;
Be provided with cooling jacket and cooling liquid inlet and cooling liquid outlet outside the mechanical seal chamber, cooling liquid enters in the cooling jacket from cooling liquid inlet, flows out from cooling liquid outlet;
The mechanical seal chamber is made of pump cover, axle sleeve and machine sealed cover, mechanical seal chamber one side is provided with the chilling chamber, logical quench liquid in the chilling chamber, and described chilling chamber is provided with quench liquid import and quench liquid outlet, quench liquid enters the chilling chamber from the quench liquid import, flows out from the quench liquid outlet;
The chilling chamber is between machine sealed cover and axle sleeve, be provided with liquid port and flow-off, described liquid port is positioned at the bottom of machine sealed cover, described flow-off is positioned at machine sealed cover side-lower, when mechanical seal was lost efficacy, leakage fluid can be discharged by liquid-discharging tube and flow-off, avoids pumped medium to enter bearing housing and damages bearing;
The mechanical seal top of chamber is provided with the outlet valve that is used for discharging the gas that produces in the running mechanical seal chamber;
Bottom, mechanical seal chamber is provided with the drain that is used to discharge the foreign matter in the Seal cage;
Be provided with little gap between pump cover and the axle sleeve, the gap can be made as 0.4～0.6 millimeter, prevents that the liquid of mechanical seal chamber and pump chamber from forming heat transfer by convection.
The employing of technique scheme, reduced the operating temperature of mechanical seal on the one hand widely, guaranteed sealing effect, the various situations when taking measures to seal failure have on the other hand been done effective protection, increase multiple guarantee for equipment normally moves, be applicable to the conveying of various high temperature medias.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a Seal cage structural representation of the present utility model.
Fig. 3 is that the A of Fig. 2 is to the interface schematic representation.
Embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
As shown in Figure 1, a kind of high temperature pump of the present utility model comprises pump chamber 1, mechanical seal chamber 2, bearing bore 3, and pump chamber 1 separates with mechanical seal chamber 2, and mechanical seal chamber 2 heat diffusion area increase, and helps reducing the temperature of Seal cage.
As Fig. 2, shown in Figure 3, the mechanical seal chamber 2 of a kind of high temperature pump of the present utility model, form jointly by pump cover 21, axle sleeve 22, machine sealed cover 23, be provided with cooling jacket 24 and cooling liquid inlet 31 and cooling liquid outlet 32 outside the mechanical seal chamber 2, cooling liquid enters in the cooling jacket 24 from cooling liquid inlet 31, flows out from cooling liquid outlet 32, take away the heat in mechanical seal chamber 2, mechanical seal chamber 2 temperature are descended;
Be provided with chilling chamber 4 between mechanical seal chamber 2 and the bearing bore 3, chilling chamber 4 is provided with quench liquid import 33 and quench liquid outlet 34, and logical quench liquid in chilling chamber 4, quench liquid prevent that by outside framework oil seal 25 sealings quench liquid from leaking.Quench liquid enters chilling chamber 4 from quench liquid import 33, flows out from quench liquid outlet 34, and quench liquid reduces the temperature in mechanical seal chamber 2 on the one hand, play air-isolation on the one hand simultaneously, the sealing surface that prevents the machine envelope produces oily charing, forms carbon granule attached to sealing surface, causes seal failure.
2 tops, mechanical seal chamber are provided with the outlet valve 27 that is used for discharging the gas that produces in the running mechanical seal chamber 2.
2 bottoms, mechanical seal chamber are provided with the drain 28 that is used to discharge the foreign matter in the Seal cage 2.
Radius clearance is 0.5 millimeter between pump cover 21 and the axle sleeve 22, prevents that the mechanical seal chamber 2 and the liquid of pump chamber 1 from forming heat transfer by convection, to guarantee that Seal cage 2 is in lower temperature.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
