The application of German Wilo pumps in sewage collection and rainwater transfer

管理员:煜科管理人气:24发表时间:2020-10-20 17:22

The progress of urbanization and thecurrent global water shortage make the rational use of water resources particularly important. The wastewater treatment process cannot be ignored. The improvement of wastewater treatment technology has auxiliary significance to environmental protection.

Wilo pumps can find a good solution for wastewater treatment needs involving pumping, mixing, ventilation, filtrationor (sewage) water disinfection. According to actual requirements, flow andhead, you can find Wilo for various media (Wilo) Water pumps, such as sewage,sludge, muddy water, abrasive or fiber-containing media.

All buildings and houses in the worldproduce wastewater, which must be treated reliably to meet sanitary standardsand avoid unpleasant smells. Therefore, when sewage cannot fall freely into thesewage pipe system, it is necessary to use efficient building technology toreduce the content of harmful substances in the waste water, reduce theconcentration of waste water (infiltration water), and divert various types ofwaste water (rainwater, sewage and wastewater) ), reduction of residues insewage treatment, utilization of various wastewater streams (grey water, urine,etc.), etc.

There are mainly the following categoriesof WILO wastewater:

FAG submersible sewage pump

* Features: FAG series submersible sewagepumps are unique in design, which can ensure a high degree of stability duringoperation and prevent sudden accidents in harsh working environments.

* Closed impeller: The pump is equippedwith a closed impeller, which can be widely used in construction and industrialdrainage operations. The impeller is mainly made of cast iron, which not onlyguarantees performance, but also prolongs the service life of the impeller.Pumps with power ≤ 7.5kW can beequipped with a reamer device. The reamer device is made of high chromiumstainless steel, which is used to ream long fibers and long solid dirt toprevent the pump from clogging.

* Short shaft design: The shorter shaftdesign can significantly avoid shaft deflection, thereby prolonging the life ofseals and bearings, and maintaining low vibration and quiet operation.

* Heavy-duty ball bearings: high-qualitylifelong maintenance-free lubricated bearings are used. All ball bearings arepre-filled with lubricating oil to ensure that they do not need to belubricated during the service life.

* Two mechanical seal systems: Twomechanical seal systems are located in the lubricating oil chamber to ensurethat the pump will not malfunction during operation.

* Cooling system: water pump with power ≥11kW, optional motor with watercirculation cooling system, can be used for dry installation or low waterlevel.

* protective device

Overheating protection: water pumps withpower ≤4kW areequipped with bimetallic temperature sensors, and water pumps with power ≥5.5kW are equipped with thermistorPTC as standard.

Leakage protection: Water pumps with power ≥5.5kW are equipped with leakagesensors in the motor cavity and oil chamber to detect whether there is liquidinfiltration inside the motor. The oil chamber leakage sensor is used to alarmwhen the external medium seeps into the oil chamber too much to prevent theexternal medium from entering the motor. If the oil chamber leakage sensorfails and the external medium seeps into the motor, the motor cavity leakagesensor will alarm and stop the motor to protect the motor from being burnt dueto moisture.

Through the control cabinet, the electricpump is protected against phase loss, overload, undervoltage and short circuit.

* Installation method: underwater orportable installation; or underwater auto-coupling installation.

* Application

FAG series products are ideal products forwaste water, sewage, surface water and clean water transportation in municipal,construction and some industrial fields.
