Shaftless screw conveyor Features and Performance Overview

Shaftless screw conveyor design , manufacture and installation to ensure the use of transportation equipment meet the requirements of a high degree of operational reliability

and minimal maintenance workload , ease of use, inspection and maintenance characteristics.
Shaftless screw conveyor structure is designed to ensure that the material flow process , non-clogging ; In the course gravity skatewheel conveyor of a drainage function .
Shaftless screw conveyor consists of shaftless spiral , U-shaped spiral groove , cover, liner, inlet and outlet port , discharge port and drive components , material from the

feed port input , the shaftless screw propellers , by the the discharge port output .
Drive:
Screw conveyor drive unit is placed at one end , the use of motor reducer and screw shaft directly connected form , without coupling, disassembly , easy maintenance, the drive

shaft can withstand Pipe conveyor bending moments and axial loads acting simultaneously squeezing pressure .
Driving means ( motor and gearbox ) using high-quality shaft mounted reducer structure, it is flexible operation, stable and reliable, no unusual noises, all combined surface

and the gearbox input and output shaft seal does not leak.
Drive motor for 380V, 3 phase , 50Hz, its protection class IP55 ( outdoor type ) , class F insulation .
Shaftless screw conveyor helical blade made ​​of stainless steel through a dedicated mold casting, which has sufficient strength and stiffness and blade surface smooth , no

glitches , but also has a suitable rotation speed , effectively ensuring the delivery gate residue in the process of dirt does not occur

Winding, blocking phenomenon, while a large amount in the case of conveying spiral blade is not deformed .
U-shaped groove resistant lining set screw conveyor semicircle shape, its arc set with shaftless spiral radius coincide to reduce excessive clearance to increase transmission

effect ; adopt high wear resistant lining nylon material, easy to install and replacement , long life .
U-shaped helical groove roll made of stainless steel , in addition to the inlet opening , the remaining part of the increase along the spiral groove flat cap closed , the entire

transfer process carried out in a sealed tank , reducing noise , reducing the odor of discharge ; in U-shaped groove bottom with discharge ports , and supporting drainage

Ball valves.
Shaftless screw conveyor parts without high-speed operation , low wear and tear to the transmission coil , equipment energy consumption , low noise .
Shaftless screw conveyor easy to install , just use expansion bolts to steel support can be fixed to the concrete foundation , it not only intermittent operation , but also to

24 hours of continuous operation.
Shaftless screw conveyor in the electrical design has overload protection function , can meet shaftless screw conveyor weather safe and effective operation.
Shaftless screw conveyor control electrical components included in the grille site electrical control box , the specific control requirements are detailed in the electrical grid

control part .
Signs on the device with a readable Chinese name of the manufacturer , device name, model number, manufacture date, number and other important parameters of the device and its

easy to see fixed in the upper position of the device , in the form of product label , size and technical requirements " signs " (GB/T13306) of

Regulations.
Corrosion equipment components : Stainless steel parts prior to clean up, and then pickling passivation treatment can be.
Device detection :
In equipment factory, the various components of the equipment for acceptance, inspection items include : visual inspection, noise detection , reliability testing, electrical

equipment testing and other testing project . Equipment at the factory to provide equipment factory inspection reports , product certification , the use of

Maintenance instructions , warranty book and purchased parts certificate .
Equipment installed in the field for two hours and no-load operation with a load operation.
Load running two hours : Equipment filling oil ( grease ) , the first Jog run simultaneously detect whether ministries space obstacles identified after continuous operation

without any trouble , running without any abnormal vibration and noise , no-load end of the run .
Run with a load : conveyor belt according to the actual throughput load operation , check the results meet the requirements of transport , after two days of continuous operation

24 hours a day without any mechanical failure as qualified.
