The screw pump is better than other types of pumps in terms of its flow rate and lift. The flow rate of the screw pump is from a few liters to several thousand liters per minute. The lift of the screw pump is mainly in the number of stages of the screw rotor.

The screw pump is better than other types of pumps in terms of its flow rate and head. The flow rate of the screw pump is from a few liters to several thousand liters per minute. The lift of the screw pump is mainly in the number of stages of the screw rotor, and the commonly used single screw. Pump products can generally reach 60-120 meters, screw pump can transport a range of medium viscosity, viscosity from water-like liquid (1cst) to (viscosity up to 1000000cst clay, glue or sludge) other media.
The rotor of the screw pump and the stator rubber sleeve are closely matched with the low speed. The normal rotation speed is 960r/min, and the shearing action inside the screw pump is also very low. When the screw pump is used in the food industry, for example, the screw pump is used to transport cherries. When the fruit is fruit, these cherry-sized fruits are not damaged by the internal passage of the screw pump. The pulseless operation of the screw pump is particularly suitable for the transport of non-destructible substances. This is one of the advantages of the screw pump.
The screw pump has better self-priming properties and only produces a small agitation or a small amount of foam when used to transport a medium containing air.
The screw pump conveys a medium containing a lot of impurities. It has a good wear resistance at low speeds, so it is also called the most durable pump. Because the stator of the screw pump uses elastic rubber sleeves of various materials, these elastic rubber sleeves are commonly used for nitrile. Rubber, butadiene rubber or imported rubber sleeves, or made of PTFE plastic and other materials. Screw pump can also be used in more abrasive media.
Although the screw pump has a wide range of applications, it has limitations in use. For example, the volume of the screw pump is larger than that of the pneumatic diaphragm pump. The product of the same parameters is large. In order to transport to a higher and further distance, it is necessary to increase the screw pump rotor and The number of stages of the stator increases the total length of the screw pump. For environments that require excessive pressure, it is sometimes difficult to improve the equipment used, especially since small pumps such as horizontal centrifugal pumps have been used. Place. However, the size of the screw pump is not limited when the site is unrestricted. Another factor in the larger size of the screw pump is the low speed, because the speed must be low, there must be a gear reducer between the motor and the pump. Belt drive. This will increase the length of the screw pump equipment, but you can use the inverter motor to directly use the variable frequency motor and the inverter to use the gear reducer device.
