Features: 1. Sewage pump uses a unique single or double vane impeller structure, greatly improving the dirt through the ability to effectively pass the pump diameter of 5 times the fiber material and the diameter of the pump diameter of about 50% of the solid particles. 2. Sewage pump mechanical seal with a new type of titanium carbide hard corrosion, can pump safe and continuous operation of more than 8000 hours. 3. The overall structure of the sewage pump compact, small size, small noise, significant energy-saving effect, easy maintenance, without building a pump, dive into the water to work, greatly reducing project costs. 4. Sewage pump seal oil chamber is equipped with high-precision anti-interference leakage detection sensor, stator windings embedded in the thermal components, automatic protection of the pump motor. 5. Sewage pump can be equipped with automatic control cabinet according to user needs, which can automatically protect the pump from water leakage, leakage overload and over-temperature, and improve the safety and reliability of the product. Float switch can be based on the desired level changes automatically control the pump start and stop, without special care, the use of extremely convenient. 7. WQ series according to user needs with dual rail automatic coupling installation system, which gives installation and maintenance more convenient, people do not have to enter the sewage pit for this purpose. 8. Sewage pump can be used in the whole head, and to ensure that the motor will not be overloaded. 9. Sewage pump has two different installation methods, fixed automatic coupling installation system, mobile free installation system.
Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.
