Introduction to the drive of the belt conveyor

Belt conveyor drive

The belt conveyor drive consists of a motor, a reducer, a coupling and a shroud. The coupling between the motor and the reducer is usually a flexible coupling, and the coupling between the reducer and the drum is a cross-slider coupling.

The wheel at both ends of the belt conveyor is called a drum. Under normal circumstances, the motive power is transmitted to the drum of the discharge end through the reducer. After the drum rotates, it is transferred to the rubber belt wound around it by the friction force. With this operation, the drum is also called the driving wheel. The other roller is only used for tensioning the tape and changing the direction of movement, so it is called the driven wheel. Is generally a hollow cylinder, commonly used pig iron cast, it can also be made of welded steel.

According to the shape of the wheel circumference, the cylinder can be divided into a cylindrical shape and a convex shape. The purpose of the protrusion on the circumference of the wheel is to maintain the center position of the belt during exercise. The amount of protrusion of the protruding portion is the difference between the radius of the middle portion of the barrel and the radius of the edge, and is usually 0.5% of the width of the wheel, but not less than 4 mm.

Roller of the belt conveyor drive: Since the belt conveyor (belt conveyor) has a long length, if only the roller support surface is suspended in the middle, the weight of the tape itself and the weight of the material to be carried will force the tape to sag. It is even possible to break the tape. Therefore, it is necessary to install a ten-bracket under the link of the article: the global crusher network to limit the sag of the belt.

The rollers are generally supported by brackets. The upper roller has a groove shape and a shape. Groove rollers are generally used for conveying bulk materials, and shaped rollers are used for conveying articles. For example, as a transporting device for semi-finished products between single machines, in order to prevent the semi-finished product on the conveyor belt from being damaged by the sub-bump surface, it can be supported by a roller of a shape or a groove shape.

For conveyors with a long conveyor distance, in order to prevent and eliminate the deviation of the conveyor belt, automatic self-aligning rollers can be used. In the load-bearing section, a set of self-aligning idlers are generally arranged every 10 sets of idlers, and in the idle section, a set of self-aligning idlers are arranged every 6-10 sets of idlers. The diameter of the idler is determined by the bandwidth. The rollers can be cast from pig iron or made of steel. Now they are also made of plastic. The rollers are supported by bearings at both ends of the roller. Most of them are made of ball bearings. Roller bearings are used under extremely heavy working conditions.

The tensioning device of the driving device of the belt conveyor: the tensioning device acts to give the conveyor belt a certain tension, prevent the slip between the conveyor belt and the driving drum, and reduce the sag of the conveyor belt between the two sets of rollers. The tensioning device is usually mounted at one end of the driven roller. The tensioning device has a spiral type, a horizontal weight type, a vertical weight type, a hydraulic type, a hoisting winch type, and the like. The first three applications are more.

Y piece, mean pipe fittings tee or tee fittings, tees and the like. It used mainly to change the direction of flow, with a branch in the main conduit to the Office. Can diameter size classification. General carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, pvc and other materials produced.

Y piece(Tee) is a three hole, namely an inlet and two outlet; or two inlets, a kind of chemical pipe outlet, there are T-shaped and Y-shaped, with equal diameter nozzle, orifice diameter pipe also, for three identical or different line Survey Office. The main role tee is to change the direction of flow.

Divided by technology

1. hydroforming

Tee hydroforming is compensated by the axial expansion of the metal material of a Branch Pipe forming process. The process is the use of special hydraulic machine, the injection of the liquid and the inner diameter equal to the three-way tube, side cylinder synchronous movement of the extruded tube by two horizontal hydraulic presses, tube after extrusion by the smaller size, the inner tube the volume of liquid with the smaller tube and pressure rise, when it reaches the three-way manifold pressure required for the expansion, the metal material in the dual role of the cylinder and the inner tube side fluid pressure and flow along the mold cavity bulge manifold.

Tee hydroforming process can be a shape, high production efficiency; competent and shoulder tee wall thickness were increased.

Due to the larger seamless tee hydroforming process equipment required tonnage currently mainly for the manufacture of standard wall thickness less than DN400 tee. Its application for the molding material is relatively low work hardening tendency of low-carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, and titanium.

2. thermoforming

Thermoforming tee tee is greater than the diameter of the tube, flattening about to tee diameter size,

Stretching branch site to open a hole; tube by heating, into the forming die, and a tensile load manifold die within a tube; tube is radially compressed under pressure, radial compression during the metal flow direction and forming the manifold branch pipe in a stretched punch. The whole process is by radial compression and stretching process tube manifold portion is shaped. Tee hydraulic bulging difference is that hot tee branch pipe metal tube is carried out by radial motion compensation, it is also known as radial compensation process.

Because after pressing tee by heating the material forming the equipment needed to reduce the tonnage. Hot links to wider adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness bias tee, often use this forming process.
