Installation method of circulating water pump of seawater direct cooling unit

Abstract

The invention discloses an installation method of circulating water pump of seawater direct cooling unit, which comprises the following steps: (1) preparing for the construction; (2) installing a temporary iron of the bearing and a formal iron of the bearing; (3) adjusting an iron of the bearing; (4) producing the cement block; (5) making a first correction level for the pump mounting plate and a grouting for the anchor bolts; (6) installing the pump housing parts like the air-sucked bell mouths; (7) making a second correction level; (8) adjusting the vertical coaxial degree; (9) making a second grouting; (10) installing an inner pipe, a spindle and the like extractable components; (11) installing a motor mount; (12) installing a motor; (13) making Trial running of the motor; (14) packing and installing other accessories; Arranging the pump support plate and the pump mounting plate together in the installation position while confirming the direction with base position of the ink line as a standard when making the first correction level, then placing the level ruler on the surface of the finishing part of the pump support plate, and adjusting the horizontal deviation of the pump support plate until less than 0.05mm / m. The installation method is characterized by simplifying the steps and saving the installation time.

Description

[0001] Technical field: [0002] The invention relates to a water pump installation method, in particular to a seawater direct cooling unit circulating water pump installation method. [0003] Background technique: [0004] The circulating water pump of the seawater direct cooling unit is mainly composed of the following parts: suction bell mouth, cylinder outer connection pipe, pump installation backing plate, pump support plate, discharge elbow, guide vane connection, guide vane, motor support, impeller chamber, Composed of impeller, guide vane body, inner connection pipe, main shaft, pump coupling, motor coupling, stuffing box body, plug-in guide bearing, packing gland, shaft end adjustment nut, etc., the circulating water pump of seawater direct cooling unit is currently in my country It is widely used in the installation of coastal large-scale thermal power units, and most of them use seawater as the transport fluid to pressurize the mechanical equipment.

[0004] The circulating water pump of the seawater direct cooling unit is mainly composed of the following parts: suction bell mouth, cylinder outer connection pipe, pump installation backing plate, pump support plate, discharge elbow, guide vane connection, guide vane, motor support, impeller chamber, Composed of impeller, guide vane body, inner connection pipe, main shaft, pump coupling, motor coupling, stuffing box body, plug-in guide bearing, packing gland, shaft end adjustment nut, etc., the circulating water pump of seawater direct cooling unit is currently in my country It is widely used in the installation of coastal large-scale thermal power units, and most of them use seawater as the transport fluid to pressurize the mechanical equipment. It is mainly responsible for supplying cooling water to the steam turbine condenser during the start, operation and stop of the steam turbine unit to cool the condensate. The steam turbine exhausts steam and provides water source for the open circulating cooling water. In normal operation, even if the circulating water pump stops running for a short time, it will cause the unit to be disconnected or an accident will occur, resulting in unpredictable losses, and its coaxial It is difficult to control the quality assurance of precision and assembly accuracy
