Pneumatic diaphragm pumps and screw pumps are both positive displacement pumps. Pneumatic diaphragm pumps are pneumatic and do not produce sparks. Screw pumps are generally electric. The principle of both is the same. They both form a movable closed space to reduce the standard volume of fluid before the pump and increase after the pump, thereby increasing the pressure in front of the pump and reducing the pressure after the pump. Pneumatic diaphragm pumps are a very commonly used conveying machinery and equipment, and are recognized and trusted by the industry. People often confuse pneumatic diaphragm pumps and screw pumps. People confuse the two because they have the same characteristics, but in fact they are also very different.

The stator of the G-type single screw pump is also called a rubber sleeve. The inner wall of the rubber sleeve is made of rubber material. Since the gap between the rubber sleeve and the rotor (screw) is small, the G-type screw pump is prohibited from idling and must have liquid for use. There is lubrication between the rubber sleeve and the screw shaft. During the rotation of the rotor (screw), friction will occur with the rubber sleeve. If the transported liquid contains fine hard particles, the service life of the rubber sleeve will be reduced. It is recommended to use abrasive liquids. Low speed screw pump. So to extend the service life of the rubber sleeve, you need to reduce the wear of the rubber.

As an important industrial pump, single screw pumps are widely used in various liquid transportation situations. However, during use, the problem of not being able to absorb liquid sometimes occurs, which seriously affects work efficiency. This article aims to explore the causes and solutions to this problem.

The stator of the G-type single screw pump is made of rubber and is a wearing part of the single screw pump. Its selection will directly affect the life of the stator. Under normal circumstances, the life of the stator is 3-6 months. If it is not selected properly, The stator may fall off the steel tube or the rubber may fall off.
