350 Dredger Centrifugal Pump

Pipeline centrifugal pumps are general-purpose equipment for conveying clear water and liquids with similar physical and chemical properties, widely used in industrial and urban water supply and drainage, high-rise building pressure boosting, fire-fighting systems, HVAC circulation and other fields [2]. According to the installation form can be divided into vertical and horizontal, according to the impeller structure is divided into closed, open and semi-open [1], the adaptable medium temperature range -20 â?? to 240 â?? [3], typical models include ISG, ISW, IRG, etc. [2] [4].
The equipment consists of impeller, pump body, sealing ring and other core components, the impeller rotates to generate centrifugal force to achieve liquid transport, the pump body plays a supporting role, and the sealing system to protect the operating vacuum. It adopts modular piping design, equipped with high-efficiency hydraulic model, supports electric drive and direct connection structure, featuring low noise, small footprint and easy maintenance. Installation requires precise calculation of suction height and ensuring pipeline sealing, and the performance curve reflects the relationship between flow rate, head and power [4]. Common faults such as air binding can be solved by filling water and exhausting air, and the bearings and sealing parts need to be overhauled regularly [2].

Centrifugal pumps use rotor dynamics, most commonly with impellers, which rotate at a high frequency to create.

Single-stage pipeline centrifugal pump with flange interface in accordance with international standards. The pump can be equipped.

YZ type liquid slurry pump is vertical single-stage single-suction cantilevered centrifugal pump structure, the impeller is semi.
