Water is among the indispensable and essential resources of life. Thinking that this resource is infinite and using it wastefully is one of humanity's greatest mistakes. Although attention has long been drawn to water among diminishing natural resources, humanity still has a long way to go on this issue. As industrialization increases, we also see that certain risks regarding water arise. Wastewater pumps, which clean and transfer wastewater, delay some dangers at least to some extent.
General Features of Wastewater Pumps
Wastewater pumps can also be called sewage pumps or septic pumps. These pumps, which are extremely important for city infrastructure, are also used in industrial areas. The successful transfer of sewage and domestic wastewater is carried out by these pumps. Today, wastewater pumps are easily used in buildings, hotels, hospitals, dormitories, and schools. They are highly effective in evacuating wastewater containing solid particles of approximately 30-50 mm. Unfortunately, these wastewaters may contain various textile pieces, plastic fragments, or papers.
Wastewater pumps are designed entirely for this evacuation process. When examined, it can be seen that different types have emerged depending on developing technology. For example, versions with shredding blades attract significant interest. Solid particles are conveniently broken down and then transferred. Wastewater pumps can be divided into different types according to application areas and features. Their price also varies depending on these features and other criteria. Generally, in terms of price-performance, they can be considered very important devices.
Wastewater pumps naturally operate in a dirty environment. This requires care when removing the pump from its operating area. To prevent such problems, wastewater pumps with slide systems have been developed. If you do not want your pump to be damaged during transfer operations, you can prefer such systems. With the slide system, the pump is pulled up after the process is completed. Necessary maintenance or repair is performed immediately afterward. This also prevents the discharge pipes from needing to be pulled up. Another feature of wastewater pumps is that they can be seamlessly integrated into wastewater collection tanks or septic tank chambers.
When the wastewater collection level is full, the float above the pump activates it. When water is about to run out, the float sends a stop signal. This cuts off the supply to the motor, and the pump stops suddenly. This system continues consistently. The transfer of accumulated water is thus successfully completed. It is important to install check valves at the immediate outlets of such pumps. The check valve should especially be of the collective type, as it prevents water from backflowing. It plays an important role in maintaining system safety.
Wastewater pumps are generally preferred in cases where sewer systems are not present or are not actively used. Since the non-use of sewer systems is rare, wastewater pumps are not always needed. Pumps specially designed for collecting wastewater from toilets, pipes, or sewage water produce highly efficient results. Thanks to their special structure, they prevent the sharp odor of wastewater from escaping. These pumps have their own dedicated collection tank. Control units are also provided with the product.
Shredding Blades Are Very Functional
In buildings or facilities located under city sewer systems, ideal wastewater pits are opened. Wastewater pumps are placed in this area, including one spare. Pumps with shredding capabilities are generally preferred first. In some cases, solid materials like tissues may get stuck on the blades and prevent them from rotating. Shredding blades are important for such possibilities. Wastewater pumps with shredding features pulverize any solid material that comes in front of them. Materials stuck to the blades can eventually burn the pump windings. Wastewater pumps should be located close to the manhole. This is important for both efficiency and safety. Architects need to pay special attention to such situations.
Points to Consider
It is recommended that wastewater pumps be placed in storage areas or warehouses. Unless necessary, these devices should not be placed outdoors or in neighborhood corners. When choosing a wastewater pump, sensor types should be prioritized. As mentioned above, these sensors will control the pump's operation and prevent noise. With sensors, the pump will not continuously activate. In addition, galvanized pipes are strongly recommended over PVC pipes. Sleeve pipes may require slightly more labor for connections. Minimizing the number of elbows is also an important detail.
Wastewater Pump Calculation
As known, pumps are generally used in positions where elevation alone is insufficient. To do this correctly, certain calculations must be applied. At this point, the relationship between head and flow rate should be focused on. Flow coefficients may vary according to the building type. For example, for schools and hospitals, it is taken as 0.7; for showers, 1.0; for small office-type areas, 0.5; and for large facilities, 1.2. Detailed tables exist for head values. These tables include information on wastewater quantity, wastewater unit, terminal fittings, and the diameter of the connection pipe.
Possible Failures in Wastewater Pipes
Thanks to technological advances, wastewater generated in homes or other areas can be transferred using special pumps. Wastewater pumps, which transfer this water to manholes and save the city from a major problem, also make a significant contribution to large treatment plants. But what are the possible failures of wastewater pipes?
- Cracking due to overheating,
- Change in the rotation direction of pipe elements,
- Incorrect type of oil selected,
- Wear of seals in the pump bearing.
