Where is the better progressive cavity pump? Which is better, progressive cavity pump or impeller pu

Shanghai Sunshine Pump Manufacturing Co., Ltd. is located in Jinshan Industrial Park, Shanghai, which is a well-known large-scale diversified enterprise integrating research, development, production, sales and service in China, with a registered capital of 80 million yuan. The leading products include: screw pumps, diaphragm pumps, submersible pumps, magnetic pumps, sewage pumps, chemical pumps, multistage pumps, self-priming pumps, gear oil pumps, metering pumps, sanitary pumps, vacuum pumps, submersible pumps, rotary lobe pumps and other categories.

The products have been recognized by various professional certifications and customers with superior performance and excellent quality. The company has a number of pump experts and all kinds of senior engineers, continuous development and manufacturing, upgraded products have come out every year. G type progressing cavity pump is a kind of progressing cavity pump, which is mainly composed of screw, pump body, bearings, seals and other components.

Its structural characteristics are: 1. Self-priming....

on the roof as well as on equipment and tools. Generally speaking, there are the following reasons for the peculiar smell in the screw chiller: The screw chiller has a peculiar smell before the food is eaten.

Before entering the screw chiller, there is a spoilage phenomenon in the food, such as spoiled eggs, meat, fish, etc.

Screw chillers that have stored fish can store meat, eggs, fruits and vegetables without washing, resulting in odor infection and spoilage.

The ventilation of the screw chiller is not smooth, and the temperature and humidity are too large, resulting in a large number of molds.

Screw pump and impeller pump are the two common types of pumps, so which one is better? The following compares from three aspects: working principle, scope of application and maintenance.

The working principle of the progressive cavity pump is to use the screw to drive the liquid from the inlet to the outlet when the shaft rotates. When the screw pump is used, it does not require the free-drug algorithm to perform multiple tuning from the bottom up, which is efficient and low noise, and can be suitable for high-viscosity liquid hunger and slow hood transportation. In contrast, an impeller pump pushes the liquid into the pipe through the gap between the impeller and the casing and flows back and forth, and the small amount of liquid swept each time often makes the pump quite high, noisy and only suitable for conveying low viscosity fluids.

Screw pump has obvious advantages in conveying high-viscosity liquids, but when transporting corrosive liquids, there will be an accumulation of corrosive products, which need to be cleaned regularly, if not cleaned in time, the equipment damage will be more serious, so maintenance is very important. The impeller pump is more safe and reliable when transporting corrosive liquids, and it is also suitable for the transportation of clean water, sewage, petroleum, chemical, food and other fluids. However, when the viscosity of the liquid increases, the efficiency of the impeller pump decreases significantly.

In summary, progressive cavity pumps and impeller pumps have their own advantages and disadvantages, and their applications are not the same. When choosing a pump, you need to choose the right type of pump according to different needs and situations. If you need to convey high-viscosity liquids, you can use progressive cavity pumps, and if you need to transfer low-viscosity fluids or corrosive liquids, you can use impeller pumps.

At the same time, special attention is also needed to pay special attention to the maintenance of these two types of pumps to ensure that the equipment is working properly.
