Introduction of screw pump stator

Standard Pump PartsNE – – StatorSE – – StatorMO – -Stator

(1) The stator is a screw sleeve with more than one threaded head of the rotor.

(2) The stator is one of the main wear parts of single screw pump. The stator will be worn because of the solid composition, pressure and viscosity of the conveying medium and the rotation of the rotor.

The stator surface is worn, will cause the rotor and the stator no longer has the seal, the stator must replace promptly.

(3) Coordination and shape of stator and rotoris the main performance parameters of the pump.

(4) The stator material has a variety of options, there are a variety of natural and synthetic elastic rubber materials, including natural rubber, nitrile rubber, EPDM rubber, FKM, etc., can provide special materials for harsh work conditions also

 

Brief introduction of the main material of stator

For different mediums, there’re different rubber formulations to choose, such as wear resistant, corrosion resistant and heat resisting

 

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.

STANDARD Pump PartsNE – – rotorSE – – rotorMO – -rotor

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

The material of rotor my company commonly used: 40Cr, Cr12mov,SS304, SS316L, 2205 and 904L

 

 

STANDARD Pump PartsNE – – coupling rodSE – – coupling rodMO – – coupling rod

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.

 

 

STANDARD Pump PartsNE – – drive shaftSE – – drive shaftMO – – drive shaft

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

Non-assembly mechanical seals

(1). To assemble mechanical seal static component into the pump cavity gland.

(2). When the mechanical seal using V-ring structure, in the installation of special attention to its V-shaped openings must face the medium (or sealing fluid) pressure direction.

(3). The mechanical seal components set on the pump shaft (also must make the V-type openings facing the pressure direction) according to the model specification to determine the position of the spring seat and according to the requirements of the adjustment, so that the spring pressure to meet the design requirements. thus ensuring the normal working pressure of the sealing surface. Tighten the screws evenly.

(4). The installation of one-way rotation (that is, the loop or hook spring transmission) mechanical seals, especially attention to the spring rotation, its rotation should be the same as the axis rotation direction, so that the spring more tightly. From the mechanical seal to the end of the static ring to see, to determine the rotation direction of the axis, clockwise direction for the right, counterclockwise direction for the left rotation

Second, operation and precautions

(1). Mechanical seals was absolutely not allowed dry turn ,the pump must be fully vented before the device starts, so that the media is filled with sealed cavities before the device can be opened.

(2). The operation of equipment should strictly follow the following procedures:

(3). Before the equipment operation, should start flushing water, 5 minutes later, start the mainframe;

(4). If you do not open flushing water, will lead to sealing surface dry friction, high temperature, seal ring burnout and seal ring coking, which will lead to complete failure of the seal. The phenomenon is more prominent in the two-terminal and multi-faceted structures.

(5). In the operation of equipment, should always check whether the flushing water is unblocked, pressure to meet the requirements;During operation, flushing water cannot be interrupted or stopped.

(6). Tthe best way to operate the pump is continuous work,If you must stop, you should rinse the backflow sediments from the pipes and pump cavities.If the equipment is to be stopped, it must be shut down for 5 minutes before the flushing water can be turned off.

Design and application of screw pump bushing

Screw pump bushing is used for coupling rod ends, which is an important part of the universal joint assembly of connecting the rotor and the drive shaft

In these moving parts, due to the friction of the long-term caused by friction, parts need to be replaced when Parts need to be replaced when the axial gap and hole wear to a certain degree of time, Therefore, we must select the material with better wear resistance for the bushing, which can reduce the wear and tear between the shaft to shaft. We must choose a better wear resistance material for the bushing, which can reduce the wear between the shaft and the shaft. When the bushing is worn to a certain extent, it can be replaced, so that it can save the high cost caused by the replacement shaft. When the bushing is worn to a certain extent, it will be replaced, this can save the high cost of replacement shaft, In general, the installation of bushing and shaft is clearance fit, this installation method cannot avoid wear, can only choose to extend the life of parts, The bushing type parts are relatively easy to produce,, the cost is relatively low.
