Abstract
The utility model relates to a filter press special pump, which is mainly used in chemical industry, through a mechanical seal, a shaft sleeve and a sealing box are arranged, especially through cooling water feed water arranged on the sealing box, the cooling water is injected into the sealing box, thereby high temperature of the mechanical seal brought because a pump shaft high speed operate is greatly decreased, the mechanical seal is capable of working well in low-temperature conditions, thereby playing a role of cooling and heat insulation, improving life of a pump body, reducing environment pollution, and decreasing production cost.
Description
Technical field: the utility model relates to a kind of pump, particularly relates to a kind of pressure filter dedicated pump that applies to chemical industry.
Background technique:, need a large amount of dedicated pumps that liquid is constantly recycled, but, be not suitable for general pump housing work because often working condition is very poor in chemical industry.Some pump does not use how long leakage phenomenon will occur, seriously influences working environment, causes the pollution in place, also can cause the increase of cost of production, makes enterprise increase unnecessary burden.For this reason, in order to solve the consequence that chemical industry uses this class pump to be caused, the utility model provides a kind of pressure filter dedicated pump with heat resisting and pressure resisting.
Summary of the invention: the purpose of this utility model just provides a kind of pressure filter dedicated pump with heat resisting and pressure resisting, it is by the pump housing, impeller nut is formed, it is characterized in that: the front end of described pump shaft is provided with impeller, rear end at impeller is provided with pump cover, and itself and the pump housing are joined, axle sleeve has been used at middle part at axle, the outside of axle sleeve is equipped with sealed case, described sealed case and rear pump cover are fixed, on sealed case, have the cooling water water filling hole, in sealed case, the outside of axle sleeve is provided with mechanical seal device, the afterbody of sealed case has used sealing gland and outside framework oil seal, used two-way bearing at the rear portion of axle, the utility model is owing to used the mechanical seal of high temperature resistance and anti-high pressure, and sealed case has been used in the outside in mechanical seal, and injection cooling water, make pump shaft under the high-speed motion of motor drives, the heat that produces is all done, guaranteed the sealing reliability of pump, simultaneously, this pressure filter dedicated pump is a kind of one step single sucking rear opening cantilever type centrifugal pump, adopts this structure to need not the pipeline that the pump housing links to each other is taken apart when maintenance or maintenance, make things convenient for maintenance widely, reduced cost of production.
Description of drawings: Fig. 1 is the structural representation of a kind of pressure filter dedicated pump described in the utility model
1. the pump housing 2. impeller nuts 3. impellers 4. pump covers 5. sealed cases
6. axle sleeve 7. mechanical seals 8. sealing glands 9. outside framework oil seals
10. axle 11. water filling holes 12. pumps
Embodiment: a kind of pressure filter dedicated pump described in the utility model is made up of the pump housing 1, impeller nut 2, impeller 3,10 on axle, it is characterized in that: the front end at described pump shaft 10 is provided with impeller 3, be provided with pump cover 4 in the rear end of impeller 3, and itself and the pump housing 1 are joined, used axle sleeve 6 at the middle part of axle 10, in the outside of axle sleeve 6 sealed case 5 is installed, described sealed case 5 is fixing with pump cover 4, has cooling water water filling hole 11 on sealed case 5; In sealed case 5, the outside of axle sleeve 6 is provided with mechanical seal 7, the afterbody of sealed case 5 has used sealing gland 8 and outside framework oil seal 9, has used two-way bearing 12 to support whole pump shaft 10 at the rear portion of axle 10.Because the utility model sealing has been adopted advanced combined mechanical sealing 7 and has been furnished with water cooling plant, cooling and temperature insulating have been played, the institute so that the utility model applying on the dyeing, have good high temperature resistance and high-voltage performance, significantly reduce the appearance of leakage phenomenon, reduced cost of production.
