Embodiment Construction

[0017] Such as figure 1 As shown, a horizontal barrel pump includes a cylinder cover 2, a cylinder 3, a pump core, an outlet flange 10, an inlet flange 14, a bearing component 15, a shaft 16, a balance pipe 18 and a bearing component 2 28 , the pump core is set on the shaft 16, a cylinder 3 is installed on the outside of the pump core, a cylinder cover 2 is installed on one end of the cylinder 3, and an outlet flange is welded on the cylinder 3 10. Inlet flange 14, bearing part 1 15 is installed on one side of the shaft 16, bearing part 2 28 is installed on the other side, sliding bearing 1 is installed in the bearing part 28, and the balance tube 18 One end of the pump is connected to the cylinder cover 2, and the other end is connected to the cylinder 3. The balance pipe 18 makes the medium pressure at the sealing end of the outlet end only the inlet pressure. The pump core includes a return section 5, a middle casing 6, guide vanes 7. Interstage transition section 8, middl...

Abstract

The invention discloses a horizontal barrel pump which comprises a barrel body cover, a barrel body, a pump core, an outlet flange, an inlet flange, a bearing component I, a shaft, a balance tube and a bearing component II, wherein the pump core is sleeved on the shaft, and the barrel body is arranged outside the pump core; one end of the barrel body is provided with the barrel body cover, and the outlet flange and the inlet flange are arranged on the barrel body; one side of the shaft is provided with the bearing component I, while the other side of the shaft is provided with the bearing component II; and one end of the balance tube is connected with the barrel body cover, while the other end of the balance tube is connected with the barrel body. The horizontal barrel pump disclosed by the invention is applicable to a design structure of a high-temperature pump with high rotating speed and high reliability; and each impeller acts on a medium, so that the pressure of the medium rises level by level, and the highest pressure is achieved on the last level, therefore, the reliability and the service life of the shaft are improved and prolonged, most axial force can be balanced out, and the horizontal barrel pump is good in tightness.

Description

technical field [0001] The invention relates to the technical field of high-pressure and high-temperature fluid conveying machinery, in particular to a horizontal barrel pump. Background technique [0002] With the expansion of the scale of petrochemical projects, the capacity of a single unit is getting bigger and bigger, and the process parameters are getting higher and higher. The design of the pump in the previous device can no longer meet the requirements of the existing device. Among these key pump equipment, the design pressure requirements for pumps are getting higher and higher, reaching or exceeding 45MPa, such as boiler feed water pumps, reactor raw material pumps, etc. The characteristics of these pumps: First, the flow rate is large, basically around 500~1500m3 / h; the head is relatively high, generally between 1500~3600m; the temperature is high, between 260℃~450℃. Contents of the invention [0003] The object of the present invention is to overcome the above...
