Screw pump type Daquan

Screw pump is a positive displacement rotary pump, which has a variable amount of delivery, self-priming ability, reversible, capable of conveying liquid containing solid particles and other characteristics, has been widely used in sewage treatment of water transport , Wet sludge and flocculant liquid. So what exactly can be divided into several categories, each type is how to work Xiaobian following one by one for you to answer. Screw pump types Daquan screw pump types are as follows: First, the number of screw pumps can be divided according to their number: single screw pump, twin screw pump, three screw pump, five screw pump four. 1. Single screw pump: only one screw. The main work is a steel screw and a rubber bush with an inner helical surface. Pumps are primarily used in the chemical and other industrial sectors to deliver a wide range of highly viscous liquids that contain fine solid particles. 2. Twin Screw Pump: There are two screws in the pump meshing work. A pair of gears transmits torque between the driving screw and the driven screw. Some oil tankers installed on the twin-screw pump. 3. Three screw pump: There are three screws in the pump meshing work. It is one of the most used pumps in rotor pumps. In the oil depot commonly used three screw pump viscous oil or fuel oil, diesel and so on. 4. Five screw pump: In the pump set with five left and right-handed double-headed screw (the main, from the rod in the opposite direction), the axial force on the screw can be self-balancing. There is a section of the screw profile involute, which plays the role of the main rod to transfer movement from the rod. Screw ends equipped with rolling bearings to ensure that the gap between the screw and pump sleeve. The nature of the liquid delivered is the same as for the three-screw pump. Second, according to the way screw suction points: 1. Single suction type: oil suction from one end of the screw, discharged from the other end. 2. Double suction type: oil from both ends of the screw inhalation, discharged from the middle. Single suction and double suction screw pump are used in the depot. In addition, press the shaft position can be divided into horizontal and vertical pumps. Tanks commonly used in horizontal pumps. In short, the variety of screw pumps, the advantages of outstanding, plays an important role in wastewater treatment. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
