Abstract

The utility model discloses a vertical-type single-stage centrifugal pump. The vertical-type single-stage centrifugal pump is characterized by comprising a pump body (17), an impeller (14), a pump cover (8), a motor (1) and a mechanical sealing (7). The pump body (17) is provided with a medium inflow channel, an impeller installment cavity and a medium outflow channel. The impeller (14) is installed in the impeller installment cavity, the axial line of the impeller is mutually perpendicular to that of the medium outflow channel, and the impeller installment cavity is provided with a sealing ring (16) matched with the impeller. A pump body is provided with the pump cover (8), and a paper cushion (13) is arranged between the pump cover (8) and the pump body. The pump cover is provided with the motor (1), the impeller is connected at the power output end of the motor through a coupler (2), and the coupler is provided with a water-stopping ring (3). The mechanical sealing (7) is installed between the pump cover and the impeller and is sleeved on the coupler of the impeller. The vertical-type single-stage centrifugal pump is compact in structure, low in size and occupied area, and convenient to install. The diameter of an inlet of the pump and the diameter of an outlet of the pump are the same, the inlet and the outlet are on the same center line, and pipelines do not need changing. The vertical-type single-stage centrifugal pump is smooth in operation, low in noise and high in assembly concentricity.

Description

Vertical single stage centrifugal pump
Technical field
The utility model relates to a kind of vertical single stage centrifugal pump.
Background technique
The traditional vertical single stage centrifugal pump have the jiggly drawback of operation, and noise is bigger in running, maintenance, dismounting are not to make things convenient for especially.
The model utility content
At above shortcomings in the prior art, the utility model provides a kind of vertical single stage centrifugal pump.
To achieve these goals, the utility model adopts following technological scheme:
A kind of vertical single stage centrifugal pump is characterized in that, has:
The pump housing (17), it has the medium flow channel, impeller is installed cavity, medium flow pass;
Be installed on impeller the impeller (14) of cavity is installed, the axis of impeller is vertical mutually with medium outflow passage axis, and the impeller installation cavity is equipped with the seal ring (16) that cooperates with impeller;
Be installed on the pump cover (8) of the pump housing, be provided with paper washer (13) between itself and the pump housing;
Be installed on the motor (1) of pump cover, its clutch end is connected with impeller by shaft coupling body (2), and described shaft coupling body is equipped with water retaining ring (3);
Mechanical seal (7), it is installed between pump cover and the impeller and is sheathed on the shaft coupling body of impeller.
The inlet calibre of described medium flow channel, identical with the outlet bore of medium flow pass, the axis of entrance and the axis of outlet are coaxial.
Install by bolt (10) attaching nut (11) between pump cover and the pump housing.
Compared to existing technology, the utlity model has following advantage:
(1) pump structure compactness, volume is little, and floor space is less.
(2) easy for installation, it is identical and on same center line to import and export bore, need not to change pipeline.
(3) pump operation is steady, noise is low, assembly concentricity height.
(4) sealing is reliable, does not have and leaks, and the axle envelope adopts high-abrasive material mechanical seals such as cemented carbide and silicon carbide.
(5) maintenance is more convenient, need not to dismantle pipeline, only need pull down the pump cover nut, takes out motor and transmitting assemblies and can keep in repair.
