It is very important to consider anti-clogging performance when designing a Sewage pump, because clogging will not only affect the normal operation of the pump, but may also cause equipment damage and increase repair costs. Here’s how the Sewage pump is designed with anti-clog performance in mind:
Impeller design: The impeller design of the Sewage pump directly affects its anti-clogging performance. Some sewage pumps use special impeller designs, such as open or semi-open impellers, which can better handle sewage containing solid particles. The open or semi-open structure allows particulate matter to pass through the impeller more easily, reducing the possibility of accumulation and blockage within the pump.
Cutting device: To further reduce the risk of clogging, some Sewage pumps are also equipped with a cutting device. These devices can cut fibrous matter and long fiber impurities to prevent them from wrapping around the impeller or pump body and causing blockage. The cutting device is usually installed at the water inlet of the pump and can effectively pretreat the sewage entering the pump body.
Drainage hole design: In the design of Sewage pump, the drain hole is usually enlarged and the runoff channel area is increased to increase the flow channel of the Sewage pump. This allows the pump to discharge sewage smoothly and reduces the occurrence of blockage. At the same time, design measures such as reducing the impeller diameter and increasing the maximum flow cross-sectional area can also effectively reduce the clogging rate of the pump.
Material selection: Sewage may contain corrosive media. Therefore, choosing the appropriate pump material also has an important impact on the anti-clogging performance. Corrosion-resistant stainless steel or special alloy materials are common choices. These materials can resist the corrosive media in sewage and reduce clogging problems caused by corrosion of pump parts.
Install a filter: Installing a filter at the water inlet of the Sewage pump is also an effective measure to improve anti-clogging performance. The filter screen can effectively prevent large particles of sediment, garbage and other debris from entering the pump, reducing pump clogging. The size and material of the filter need to be selected according to the specific use conditions to ensure that it can prevent blockage.
To sum up, the Sewage pump is designed to improve its anti-clogging performance through various methods such as impeller design, cutting device, drain hole design, material selection and installation of filters. These design measures can effectively reduce the clogging rate of the pump and improve the operating efficiency and reliability of the Sewage pump.
