1. Overview of CZ petrochemical process pump products:
CZ chemical pump is a single-stage single-suction cantilever centrifugal pump, mainly used in petroleum, chemical, synthetic fiber, fertilizer, power station, metallurgy, food and medicine and other industrial sectors to transport clean or particle-containing liquids, low-temperature or high-temperature liquids, medium The temperature of the conveying medium is generally -45℃~180℃.
The performance range of the chemical centrifugal pump includes all the performances of the IH series chemical pump, and its efficiency, cavitation performance and other indicators all exceed the IH pump, and can be interchanged with the IH pump. The pump speed is divided into two types: 2900 and 1450 (r/min).
2. Structure description of CZ petrochemical process pump:
The pump is a single-stage, horizontal, volute casing pump. The pump body is supported by feet, and the single-suction impeller inhales axially and discharges radially.
The hydraulic balance is carried out by the balance hole on the auxiliary blade or impeller.
The pump body of some specifications is designed as a double volute casing to balance the radial force.
The shaft seal can be sealed with soft packing (can be cooled or not), and can also be used with single and double mechanical seals of various structures (balanced type can be used).
The rated pressure rating of the suction and discharge pipe flanges is the same.
The bearings are lubricated with clean No. 22 machine oil.
Rotation direction of the pump: viewed from the motor end, it rotates clockwise.
