The Function And Description Of Pneumatic Clutch

At present, China's energy situation is becoming increasingly tense. In order to further promote resource conservation and comprehensive utilization and ensure the sustainable development of China's economy, the country is vigorously accelerating the process of building a conservation-oriented society. According to statistics, more than half of the annual power generation in China is used for electric motors, so the electric motor, which is a large consumer of electricity, has great potential for energy saving. At present, a large number of motor-driven heavy-duty equipments are widely used in mining, petroleum, chemical, electric power, metallurgy, shipbuilding, lifting and other industries. Currently, rigid couplings are often used between heavy-duty equipment and high-power motors. . Since heavy-duty equipment often requires a large torque from the motor when starting, and a large amount of energy is output during a short start-up process, the load on the motor at start-up is large.

When the conventional coupling is rigidly connected directly between the heavy-duty equipment and the high-powered motor, it is easy to cause a high starting current and a long starting time when the heavy-duty equipment starts, and a large starting current for a long time (for a rated current of 5) -7 times) easy to burn the motor, the impact on the internal power grid of the enterprise is also large, and will have adverse effects on the normal operation of other electrical equipment, while increasing the capacity of the transformer; a large number of statistical results on heavy equipment (such as ball mill) It is indicated that the motor power selected by the motor power heavy-duty equipment selected according to the direct start process with load is often much larger when the actual operation is normally performed. If the motor is selected according to the load of the starting process, it will cause "Malaysia" when the equipment is in normal operation. The phenomenon of pulling the trolley" causes the cost of the motor selected for the heavy-duty equipment to be too high, and the motor power appears to be too large when the heavy-duty equipment is working normally, and the wind loss, iron loss, mechanical loss, etc. generated by the motor with excessive power The waste of energy is serious. Simply adopting different step-down starting methods (Y-△ switching method, auto-coupling step-down method), although reducing the starting current, but also reducing the starting torque, can not meet the requirements of a large number of heavy-duty equipment high load .

The energy-saving and environment-friendly pneumatic friction clutch produced by the heavy-duty equipment adopts the flexible friction controllable connection method to replace the rigid connection mode of the traditional coupling, which not only solves the shortcomings of the traditional rigid coupling of the heavy-duty equipment, but also The range improves the overall performance of heavy-duty equipment. The use of this high-performance pneumatic friction clutch in heavy-duty equipment is convenient to realize the no-load pneumatic of the heavy-duty equipment motor in the clutch. After the motor reaches a stable speed, the pneumatic friction clutch is engaged to complete the rapid and smooth operation of the heavy-duty equipment. Start up. The effective protection of heavy-duty equipment and electric motor is realized; the current of high-power motor of heavy-duty equipment is greatly reduced, and the impact on the power grid is significantly reduced; the power of the selected motor is significantly reduced (for example, the 3600×6000 ball mill of a domestic steel mining enterprise was originally adopted) The motor power used in the rigid coupling is 1500KW, and the motor power is 1250KW after the pneumatic friction clutch. The ball mill works normally and the power is reduced by 20%), which makes the equipment investment small and the running cost low; the pneumatic friction clutch adopts advanced PLC control mode, powerful control function, easy to realize communication with the host computer, realize microcomputer control; the pneumatic friction clutch has reasonable structure, convenient installation and use, as a basic component suitable for heavy-duty equipment matching and rigid connection with existing belt The heavy-duty equipment of the shaft is modified.

Energy-saving and environmentally-friendly pneumatic friction clutch parameters for MQL series heavy equipment

● Depending on the inner diameter and the size of the core groove, the bearings of the motor are calibrated for easy installation. The CDP air-pressure clutch is used to soften the start, reduce the starting power and reduce the engine capacity. Also suitable for high speed rotation.

Torque range (N. m, air pressure 0.6MPa)

DFE . QFE stabilizes the maximum air compressor clutch that supplies torque.

● HC series large air compressors are divided into two types: DFE type (single row disc) and QFE type (double row disc). Not only can it produce the maximum torque, but it is ideal for high-speed start and stop because of its low inertia design. Achieve smooth movement. Link, the reactivity when disconnected is quite good.

<single position type>

A secure fixed position connection is made by the ball stop.

The single position type air pressure clutch is formed by a combination of a gear and a ball stop device. After one rotation, it stops only at one fixed position. Do not slip, the link is true. It is most suitable for output, into the dynamic bearing and the two gears need to be on time and accurately connected at a fixed position.

★ There is also a sealed type 5HPSP-E.

Air brake

BSM

<miniature>

The function of the air brake is condensed, which is most suitable for lightweight and automated mechanical automation.

●The miniature air brake is a combination of an adapter that mounts a CSMP (micro) air pressure clutch to the brake. It is an indispensable product for miniaturization of all machines in order to reduce the weight and size of the brakes.

BSB

<Standard type>

Superior heat release and large heat capacity can also be used under cool conditions.

●The heat release effect is very good, and it is most suitable for the tension control in continuous sliding and high-frequency, high-load and other extreme conditions, such as high torque, smooth stop and other braking. The friction plate is not only thick, but also has a long life, and the two plates can be easily replaced alternately.

BDP

A large air brake that achieves smooth motion and low inertia.

●The large-scale air-pressure clutch brake "HC series" is divided into two types: DFE type (single disc) and QFE type (double disc). Due to its low inertia, it is most suitable for high-speed start and stop applications for smooth sliding. The friction plate is made of non-asbestos, and the pressure plate with the heat sink is made of a protrusion, so that the cooling effect is increased and the stable torque is supplied.

BMA, BMN

<template type>

Simply connect directly to the flanged motor. Save parts and assembly man-hours during installation.

● The BMA's input power side can be directly mounted with a standard flanged motor. The output power side can be easily assembled into an air brake motor if it is equipped with a reducer. The reducer can be easily mounted on the flange face with the input dynamic bearing

Wait for machinery. The reflection performance is good, and it has a superior heat release effect due to the use of the desktop rated disc, and is suitable for high-frequency braking.

BSE

<Spring Brake Type>

The spring is guided by a simple action to improve the reliability in an emergency.

● The BSE type brake is braked by a plurality of springs and released by air pressure.

If an accident occurs during air pressure decompression or when the power supply is cut off during a power failure, it can be automatically braked to prevent danger. Simple construction and easy maintenance.

DFB, QFB

High torque and superior cooling efficiency, high reliability, high torque air brake.

●The spring-loaded large-scale air compressors are classified into a single disc type DFB type and a double disc type QFB type.
