A urea condensate pump

Abstract

The invention discloses a urea condensate pump. The pump comprises a first shaft and a second shaft which are arranged coaxially, wherein the right end of the first shaft is detachably connected with the left end of the second shaft; a bearing sleeve, a third shaft sleeve and a couplingsleevesthe second shaft in sequence from the left end of the second shaft; a bearing seat and a bearing seat end cover connected with the bearing seat sleeve the bearing sleeve and the third shaft sleeve separately; a bearing sleeves the third bearing sleeve, and the axial movement of the bearing along the third shaft sleeve is limited by a round nut; the bearing seat end covercommunicateswith a bend pipe; the second shaft is sleeved by a stopper ring, a second shaft sleeve and a fixed sleeve from the left end to the right end; the second shaft sleeve is sleeved by a first shaft sleeve, a spring, a movable ring, a static ring and a cooling sleeve from the left end to the right end; a first pipe joint communicatingwith the side wall of the cooling sleeve is a coolant inlet, a second pipe joint communicatingwith the side wall of the first shaft sleeve is an outlet; a pump port, an impeller sleeve, an impeller and a medium shell sleeve the first shaft in sequence from the left end; a diversion disk communicating with the pump outlet sleeves the impeller sleeve by the bearing; and the axial movement of the impeller along the first shaft is limited by a fourth screw.

Description

Technical field: [0001] The invention relates to a urea condensate pump, which is used for transporting cooling liquid in the process of urea processing. Background technique: [0002] At present, the urea chemical industry will produce high-temperature and high-pressure steam during the production process, and it is necessary to cool the urea steam to prevent the occurrence of over-temperature and over-pressure hazards. The current condensation generally uses pumps to transport condensing media for cooling, which cannot solve the problem of over-pressure in the production process. temperature overpressure problem. Invention content: [0003] The object of the present invention is to provide a urea condensate pump aiming at the problems existing in the prior art. [0004] In order to achieve the above object, the present invention adopts following technical scheme to realize: [0005] A urea condensate pump, comprising a first shaft and a second shaft coaxially arranged,...
