Duwan Environmental's AV14-4 Sludge Pump refers to the entirePlease provide the Chinese content you would like translated.Submersible pump unit, including the pump and the drive motorCables, automatic couplers, rods, lifting devices, andOther auxiliary equipment.

Each submersible pump is fully equipped with the necessary accessories, fasteners, and spare parts for safe, effective, and reliable operation.And the on-site stainless steel control cabinet。

Submersible污水泵 is a vertical, single-stage, automatic-coupling, non-clog impeller pump; the submersible motor is connected to the pump body, and the pump must be capable of conveying raw and unfiltered wastewater. The submersible pump should operate safely, stably, efficiently, and continuously under specified operating conditions. The continuous operation cycle should not be less than8000 Hour, lifespan of no less than15 Year.

Submersible pumps must operate smoothly without vibration or cavitation throughout the entire design load range. All rotating parts of the pump (including the motor) should undergo static balance tests during manufacturing and dynamic balance tests after assembly, with an accuracy of at leastISO1940 G6.3Please adhere to the strict quality standards.

Submersible pumps should be capable of continuous operation (daily) under full immersion conditions.24Operates on an hourly basis and is suitable for intermittent operation (can meet hourly requirements).10New requirements for starting and stopping the equipment, and returning to normal operation after a long-term shutdown.

Pumps with an automatic coupling installation require a discharge bend, a self-coupling base, and either a stainless steel guide rail or cable with a lifting chain for automatic positioning. The pump should be able to slide freely from the top of the pump pit to the self-coupling base under the guidance of the rail or cable. The pump should automatically couple securely to the base. The entire weight of the pump, including the motor, is supported by the self-coupling base, with no part of the pump or motor to be in direct contact with or placed on the pump pit bottom plate or its supports.

Each pump should be equipped with a lifting lug suitable for the hoisting winch at the center of gravity of the pump.

Each pump is 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 wire rope devices, and it can be automatically connected to the discharge elbow support with 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 down. 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 immersion in10 The parts must be marked for assembly and equipped with locating pins where necessary, ensuring they can be correctly reassembled and positioned on-site without damage, even when submerged in water.

Each pump must have a stainless steel nameplate securely fastened in a prominent location, featuring embossed numerical markings. Each pump is equipped with a lifting stainless steel lifting lug, positioned near the pump's center of gravity, and an accompanying stainless steel lifting chain.

The dedicated lifting device for submersible pumps must ensure that maintenance personnel can safely and reliably lift the pump from ground level (equipped with a special chain conversion ring and fastening components for the ring).

Submersible Pump Acceptance:

Duwan Submersible Slurry Pumps undergo a comprehensive set of pre-shipment procedures.Quality control systems are in place to ensure that all factors affecting product safety, reliability, operational performance, and long-term durability have been considered, and that necessary tests, inspections, and calibrations are performed on processing, inspection, and testing equipment.

Wastewater pumps should be manufactured, inspected, tested, and accepted in accordance with relevant standards, specifications, and regulations.

Materials used in the manufacturing of submersible sludge pumps are inspected, and a material factory pass certificate, material inspection, and test records are issued.

In accordance with the requirements of relevant standards, specifications, and regulations, static and dynamic balance tests are conducted on the main rotating components of the pump.

All pressure-bearing components of the submersible pump, including the cooling jacket, must be subjected to static pressure tests in accordance with regulations within the manufacturer's workshop. The static pressure test must not be less than the closed lift (zero flow).2 Please provide the Chinese content to be translated.0.2MPa。

Under the specified test pressure, no part of the pump shall exhibit deformation or any signs of deformation, nor shall it have other defects. The performance tests of the submersible pump and the motor shall be conducted in accordance with the standards specified, and the permissible deviations for each indicator shall comply with the relevant standards.

For the pumps supplied, Duane Environmental providesSubmersible Sewage PumpThe performance curve should start from the closed-point (zero flow) and extend at least to the rated flow point.130%Please include the following details: pump position number, pump model and specifications, test speed, test medium and temperature, flow rate.—Elevation curve, efficiency curve, shaft power curve, design operating point.
