Each pump must be equipped with a fixed discharge connection elbow. The pump should be capable of being lowered into the well and positioned using two parallel rods or cable guides, and it should be able to connect the pump discharge outlet automatically to the discharge elbow bracket via an automatic coupler. Additionally, it should facilitate the easy lifting of the pump above ground level during maintenance.
The seal between the pump housing and the outlet bend support can be conveniently adjusted by moving the pump vertically downward. The outlet bend support and the sliding guide coupling device should be considered an integral part of the pump equipment. The entire weight of the pump equipment should be securely pressed against the outlet bend by the contact between the flanges of the automatic coupling device.
Submersible pumps and their accessories, cables, etc., should be capable of being immersed in10 The parts should run continuously in water without damage and should have reliable sealing. Assembly marks must be made on the components, and locating pins should be provided where necessary to ensure correct reassembly and positioning on-site.
Duwan Environmental Protection WQR Type, AF Type SubmersiblePumps utilizedFrontierHydraulic model, energy-saving, and reliable performance.
·Standard of Execution: Complies with international standard ISO2858 and meets the specifications of the regulations.
The vibration of the pump conforms to the requirements of GB/T29531-2013.
The pump noise conforms to the requirements of GB/T29529-2013.
·All parts are manufactured according to ISO or GB standards.
·Bolts, nuts, and other fasteners, as well as mechanical tolerances, comply with the latest ISO or GB standards.
AF Submersible污水泵 Structure and Performance Description
·Bearings: Choose SKF or NTN bearings, properly configure the bearings to extend the pump's lifespan.
·Motor: The motor features F-grade insulation, with a higher operating temperature of 155°C and a protection rating of IP68.
· Mechanical Seals: Employ a double mechanical seal in series, operating independently, to isolate the motor from the pump, providing dual protection for the motor.
·Impeller: WithPlease provide the Chinese content to be translated.Excellent flow and speed for efficient liquid transportation, preventing clogging.
· Pump Housing: Engineered with CAD/CAM technology for high efficiency and reduced wear.
·Shaft: Coaxial with the pump and motor, featuring a shaft-end seal to prevent contact with the pumped medium, thereby protecting the shaft from corrosion.
·Axial extension design is kept as short as possible to minimize the deflection of the rotating shaft, reduce vibration, extend the service life of mechanical seals and bearings, and lower operating noise.
· Monitoring System: The stator is equipped with three series-connected thermal control switches. They are in a "normally closed" state at room temperature, and open when the stator temperature reaches 125℃.
· The oil chamber is equipped with a leak detection probe. Used for leak detection. When the mechanical seal on the pump side leaks, the oil-water ratio in the oil chamber
At a certain concentration, the oil-water probe emits an alarm signal (the indicator light illuminates) and automatically cuts off the power, stopping the pump from operating.
·Buoy Switch: In the event of mechanical seal leakage on the motor side, with liquid entering the buoy switch chamber and reaching a certain height, the buoy switch will emit an alarm signal (the indicator light will illuminate) and stop the pump, prompting maintenance personnel to inspect and replace the mechanical seal on the motor side.
·The assembly includes an electric motor, impeller, pump housing, and cover, etc.
·The pump housing features a mounting foot for stable installation and operation.

Installation Requirements
Submersible pumps and installation sequence, as well as technical requirements, should be in accordance with the manufacturer's installation manual.
Before installation, Jiangsu Du'an Environmental ProtectionPackaging StaffProtective stickers packaging to prevent component damage must not be peeled off prematurely.
The installation location and elevation of the submersible pump should comply with design requirements, with the plane position deviation not exceeding±10mm, elevation deviation must not exceed ±20mm.
The submersible pump base should be adjusted to be level, with the deviation not exceeding1/1000。
The two shaft rods of the centrifugal submersible pump must be installed vertically and parallel. The deviation in verticality should be less than1/1000. Total length must not exceed 4mm, parallel deviation less than 2mm.
When using a long submersible pump cable, ensure proper cable fixation.
The submersible pump outlet flange must be aligned and straight with the pipe flange for a tight fit.
