Press the control motor rotation direction:
Irreversible electromagnetic starter: can only make the motor rotate in one direction Reversible electromagnetic starter: can make the motor rotate in both positive and negative directions. The starter can be divided into two categories according to function: one-way control and reversible control.
Power: maximum power 10KW, maximum reversible power 18.5KW
This corporate standard specifies the product classification, requirements, test methods, inspection rules, markings, packaging, transportation and storage requirements for BQC series explosion-proof magnetic starters (hereinafter referred to as starters).
This corporate standard applies to the design, manufacture and inspection of starters.
The starter is mainly applicable to hazardous areas in zone 1 or zone 2 in explosive gas atmospheres, explosive gases and vapours are IIB or IIC, T4 and below, as the direct starting and stopping of three-phase asynchronous motors that control AC 50Hz and rated voltage to 380V Or reverse use. With overload, phase failure, loss of pressure, short circuit protection.
1. The starter consists of a flameproof enclosure and a vacuum body, and the vacuum body is housed in a flameproof enclosure.
2, starter shell is round, shell cover for the rotary tooth structure, the body part of the case for the junction box, used to introduce the power cable and leads out the motor cable, and to take measures to prevent explosion, in order to achieve explosion-proof requirements. On the right side of the housing there is a switch handle and a stop button to isolate the switch. There is a mechanical interlock between the two. Only after the stop button is pressed can the handle be turned and the cover can be opened.
3. All components of the vacuum body are mounted on the bottom plate. The front side is equipped with a vacuum contactor, a motor integrated protector, an overvoltage absorption device, an intermediate relay and a fuse, and the back is equipped with an isolated reversing switch, a transformer and start and stop buttons. These electrical components generally do not need to be adjusted or replaced.
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
