Introduction of screw pump stator
Rubber Materials Details
(1). One of the most important parts is the stator in screw pump, the high quality of the stator is determined by the vulcanization process of the rubber.
(2). Strict control of raw materials selection, strict control of the mixing process and the final analysis in the laboratory, to ensure the high quality of products and long service life.
(3). In a close cooperation with our customers we define the properties of the material to fulfill the customers demand. In addition, based on our long-term experience in plastic injection, concerned about the safety of production and reduce costs, and the results are compared to ordinary products, we have a better performance of the selected material solutions.
Tubes Material:
(1) The stator tube options include low carbon steel and stainless steel ,
(2) Special materials: 316L, 904L, and CD4MCu dual phase stainless steel ,which can operate at temperatures as high as 150 degrees
The material of stator my company commonly used:
Rubber: NBR; EPDM; FPM; SI
Stator shell: Q235; SUS304; SUS316L
Introduction of screw pump rotor
(1) The center part of the screw pump is composed of rotor and stator. Screw rotors are usually made of metallic materials and are made into unique twist angles through special cutting machines. A special structure consisting of a steel rotor and an elastic stator makes it capable of conveying materials containing solid particles.
(2) The rotor is placed in the stator, sealed together in a helical structure. When the rotor rotates, the internal continuity of the stator is running, the liquid in the closed space runs continuously, conveying out from the suction side of the "No pulsation" and "quantitative" transmission.The outer thread and the thread of the rotor are made according to the special processing;
Material of rotor
Carbon steel, stainless steel, SS304, SS316L,904L etc.
The material of rotor my company commonly used: 40Cr, Cr12mov,SS304, SS316L, 2205 and 904L
The introduction of screw pump coupling rod
(1). The connecting Rod Group consists of connecting rod, universal joint,coupling rod, guide bush, rubber rings, and a rubber sheath, connecting rod pin, retaining sleeve,steel wire rings, drive shaft, etc.
(2). The connecting Rod Group is in addition to withstanding not only the force of drive shaft, but also to bear the force of its own swinging longitudinal and transverse, the size and direction of these forces are cyclical, so the connecting rods are subjected to alternating loads such as compression and stretching.The size and direction of these forces are cyclical, so the connecting rods are subjected to force of compression, stretching and so on.
(3). The coupling rod must have sufficient fatigue strength and structural stiffness. If the fatigue strength is insufficient, it will lead to break the connecting rod body or connecting rod interface, and then produce the major accident whole machine damage.
(4). If the rigidity of the connecting rod is not enough, it will cause the bending deformation of the rod body and the universal joint, resulting in the eccentric grinding of the coupling rod, guide bush, thecoupling rod bush, etc.
Function of connecting rod:
The connecting rod is used to connect the drive shaft and the rotor , and transmit the actuator force to the rotor, thus driving the rotor to rotate the motion. According to the requirements of the media, the joint shaft can be installed with a broken bridge aid flow device
Material of connecting rod:
The main damage form of the connecting rod is fatigue fracture and excessive deformation. Generally, the fatigue fracture area is three high stress areas on the connecting rod. The working condition of the connecting rod requires that the connecting rod has high strength and anti-fatigue performance, and it also requires sufficient rigidity and toughness. Traditionally, the materials used in the process of connecting rod are 304, 316L, 40Cr, 2Cr13, 2205, 904L and so on.
The material of coupling rod we commonly used :
SUS304 ; SUS316; 2Cr13, 40Cr, 2205 , 904L etc.
Introduction of drive shaft
(1). Drive shaft is the part for connecting and assembling various accessories, and turning cylindrical object parts.
(2). The drive shaft is composed of a shaft tube, rubber sheath, seal and a universal joint .
(3). The screw pump drive shaft is the drive power transmission to the coupling rod, thus driving the rotor rotation. Several components are connected by a universal joint or a flexible shaft.
(4). The drive shaft material has 304, 316L, 40Cr, 2Cr13, 2205, 904L, also needs to make the adjustment qualityor surface treatment of hard chromium .
The material of drive shaft we commonly used:
SUS304 ; 304, 316L, 40Cr, 2Cr13, 2205, 904L
Screw pump drive shaft common sense:
(1). The overall layout of the screw pump determines the dimensions of the drive shaft and their range of change. If the drive shaft is damaged, worn, deformed, and loses its dynamic balance, will cause abnormal sound and vibration in the running screw pump,When serious, it can cause the related parts to be damaged,So the rationality of the drive shaft design will directly affect lifetime of universal joint assembly and drive shaft, and efficiency of universal drive and stability of screw pump operation
(2). To usedrive shafts along with different drive products, the surrounding work environment is more complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, saline, radiation and other conditions, these are important factors to be considered when selecting the drive shaft
(3). The drive shaft is a rotating body with a high rotational speed and less support, it's dynamic balance is very important.In general, the drive shaft before the factory to carry out a dynamic balancing test, need to adjust on the balance machine.
There are 6 major functions of the drive shaft
(1). Improve the rotor and its composition of product quality
(2). Reduce noise
(3). Reduce vibration
(4). Improve the support components (such as the joint shaft, coupling, universal Joint Assembly) life
(5). Reduce the user's discomfort
(6). Reduce the power consumption of the product
