What are the requirements for the installation foundation of sewage pumps?

The installation foundation of sewage pumps is a key factor in ensuring the stable operation of equipment. In order to meet the requirements of vibration and dynamic loads generated by sewage pumps during operation, the stability of the foundation is crucial. If the foundation is not stable enough, the pump body may be displaced or vibrated, resulting in equipment damage, loose connection parts and reduced work efficiency. Therefore, it is necessary to choose a solid ground or a compacted concrete foundation, and the contact surface between the foundation and the ground should be kept flat. Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. recommends the use of high-strength reinforced concrete when designing the foundation of sewage pumps to ensure that the pump body can withstand the vibration and pressure from the pump during operation and avoid sinking or cracks in the foundation.
Bearing capacity is another important indicator of the installation foundation of sewage pumps. During the operation of the pump, components such as the pump body and motor will generate a certain amount of gravity and vibration force, which requires the foundation to have sufficient strength to withstand these loads. Especially during the installation of large-flow and high-power sewage pumps, the weight and vibration of the pump body are particularly obvious. If the bearing capacity of the foundation is insufficient, the pump body may tilt or shift, thereby affecting the working efficiency and service life of the pump. Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. fully considers the weight and operating load of different types of pumps during the design and selection process to ensure that each equipment can operate stably on a suitable basis.
During the installation of the sewage pump, the horizontal control of the foundation is also crucial. The levelness of the pump body directly affects its normal operation. If the pump body is not level, it may cause uneven clearance between the pump impeller and the pump body, thereby reducing the working efficiency of the pump and may cause excessive wear and even failure. To ensure the levelness of the equipment, Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. recommends ground measurement and foundation construction quality inspection before installation to ensure that the levelness of the installation location meets the requirements.
The design of the drainage system of the foundation is also a factor that cannot be ignored when installing the sewage pump. Since the sewage pump may leak water due to improper operation or equipment failure during operation, the design of a reasonable drainage trough or drainage pipe on the foundation can effectively prevent water accumulation from damaging the equipment. In large sewage treatment plants or industrial drainage systems, the design of the drainage system is particularly important. Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. usually provides detailed drainage plans according to actual conditions in the design and construction of pump stations to ensure that the foundation remains dry and free of water accumulation, and to prevent the equipment from being eroded by water.
In addition, the centering and axis adjustment of the sewage pump are also important links in the installation foundation requirements. The axis of the pump and the axis of the motor must be strictly aligned, otherwise it will cause excessive wear of the bearings, increased vibration, and may even cause serious faults such as pump shaft breakage. Therefore, during the installation process, professional tools must be used for centering to ensure that the axes of the pump and motor are consistent.

What are the sealing methods of sewage pumps?

Advantages of mechanical sealing technology
As the most widely used sealing method in sewage pumps, mechanical seals have become the first choice in the industry with their excellent sealing performance and long service life. Its main components - sealing rings, dynamic rings, static rings and springs, achieve effective sealing of the medium through precise relative movement. Mechanical seals have excellent corrosion resistance, wear resistance and high temperature resistance, can work stably under high pressure environments, significantly reduce wear during equipment operation, and extend the overall service life of the equipment.
Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. continues to innovate in mechanical sealing technology, providing personalized solutions for different working conditions and media characteristics to ensure excellent sealing effects in various extreme environments. This customized service not only improves the customer's experience, but also lays the foundation for the sustainable development of the company.
Application scenarios of packing seals
Packing seals are an ideal choice for some low-pressure sewage pumps due to their simple structure, low cost and easy installation. By filling the packing material between the sleeve and the shaft of the pump and applying pressure with the help of the packing gland, the packing seal can effectively prevent leakage. Although its sealing performance is inferior to that of mechanical seals, it still shows its unique advantages in situations where equipment maintenance requirements are high.
Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. provides packing seal solutions for the needs of low-pressure sewage pumps, especially for systems that require frequent maintenance and simple operation. The adaptability of this sealing method enables it to be flexibly applied in a variety of working conditions and environments, and continues to occupy a place in the small and medium-sized sewage pump market.
