What are the classifications of electromechanical equipment?
In production life, are inseparable from the role of electromechanical equipment. One of the most widely used electromechanical equipment is metal cutting machine tools, lifting equipment. There are many types of electromechanical equipment, to master a certain knowledge of the classification of electromechanical equipment, to help us systematically understand the electromechanical equipment, or then the actual use, can be grasped in a timely manner. Generally according to the use of electromechanical equipment can be divided into three categories: industrial electromechanical equipment, information electromechanical equipment, people's livelihood electromechanical equipment. 1, industrial electromechanical equipment is used for the production of mechanical and electrical equipment. For example, ordinary lathes, ordinary milling machines, CNC machine tools, wire cutting machines, food packaging machinery, plastic Gan. Machinery, textile machinery, automated production lines, industrial robots, motors, furnaces, etc., all belong to the industrial class of electromechanical equipment. 2, information class of electromechanical equipment is used for the collection, transmission and storage of information processing of electronic and mechanical products. For example, computer terminals, communication equipment, fax machines, printers, copiers and other office automation equipment, etc., are information-class electromechanical equipment.3, livelihood-class electromechanical equipment is used in the field of people's lives of electronic machinery and mechanical and electronic products. For example, VCD, DVD, air conditioning, refrigerators, microwave ovens, automatic washing machines, automotive electronic products, 9 therapeutic equipment and fitness and sports machinery and so on are people's livelihood electromechanical equipment. In addition, according to the national economy industry classification and code, the national industrial and agricultural product classification and code and other national standards of classification, classification of electromechanical equipment is divided into general mechanical class, general electrical class, general, special instrumentation class, special equipment class four categories. 1, general mechanical class machinery manufacturing equipment (metal cutting machine tools, forging and pressing machinery, foundry machinery, etc.); lifting equipment (electric hoist, loading and unloading machines, all kinds of), lifting equipment (electric hoist, crane, elevator, etc.). Cranes, elevators, etc.); agriculture, forestry, animal husbandry, fishery machinery and equipment (such as tractors, harvesters, a variety of agricultural and sideline product processing machinery, etc.); pumps, fans, ventilation mining suction equipment; environmental protection equipment; carpentry equipment; transportation equipment (railway vehicles, automobiles, Kangtuo car, ships, aircraft, etc.), etc.; 2, general electric power station equipment; industrial boilers; industrial turbines; motors; power tools; electrical Automation control devices; electric furnaces; electric welding machines; special equipment for electricians; electrician test equipment; daily appliances (refrigerators, air conditioners, microwave ovens, washing machines, etc.), etc. 3, general, special instrumentation automation instrumentation, electrical instrumentation, specialized instrumentation (meteorological instrumentation, seismic instrumentation, teaching instruments, medical instruments, etc.); composition analysis instrumentation; optical instrumentation; testing machines; experimental instrumentation and mounting T etc.; 4, the category of specialized equipment
What equipment is needed for the production of motors?
Looking for acquaintances to go to the relevant motor manufacturer field test to understand. Machining equipment (often, milling, grinding), stamping equipment, drop, press, testing equipment, insulation treatment and many others. You can also look at the relevant motor production process aspects of the book and so on.
Power facilities mainly include what 15 points
The power facilities of the air conditioning room mainly include compressors, motors, fans and other moving equipment and cables, distribution boxes, switchgear and other static equipment.
What electrical motor equipment is included in the main circuit 5 points
High-voltage: the electrical equipment of the substation are: transformers (high-voltage to low-voltage, low-voltage to high-voltage), switchgear (equipment to connect and disconnect the circuit), transformers (voltage and current two), measuring instruments (voltmeter and ammeter, etc.), protective appliances (fuse and lightning arrester, etc.), control panels and distribution panels (most of them are used for low-voltage power distribution operations, distribution panels). For low-voltage power distribution operations, distribution panels are equipped with measuring instruments switch fuses transformers, etc.).
Low-voltage: the main knife switch or other switches switching switch fuses and circuit breakers, etc., for power trailing devices in the main contactors control relays starters and main electrical appliances.
Specific power equipment depends on the specific conditions to select lines and equipment.
What are the main industrial power equipment?
1 motor, where the equipment to be moved need to be driven by the motor, so the most used is the motor. 2 lighting equipment, lighting is also the most used, regardless of industrial civil are very common. 3 electric heating equipment, not as much as the first two kinds of quantity, but the power consumption is large. 4 the actual use of the largest is the control of the Bean and protection equipment, such as a variety of electrical switches, high and low voltage protection equipment, etc.
Which mechanical equipment is the most used in the industrial sector?
Which mechanical equipment to use three-phase asynchronous motor
All equipment can be used to three-phase motor, single-phase motor is to consider the convenience of single-phase power grid in our country is common, and the three-phase power is less, so I feel that three-phase motors with less.
What are the main contents of the energy-saving project of the motor system?
The main contents of the motor system energy-saving project are as follows:
1, update the elimination of inefficient motors and high power-consuming equipment
Promotion of energy-efficient motors, rare earth permanent magnet motors, high-efficiency fans, pumps, compressors, high-efficiency drive systems. Renewal and elimination of inefficient motors and high power-consuming equipment; the use of energy-efficient motors and systems related to power-saving equipment newly installed motor system. Gradually limit and prohibit the production, sale and use of backward and inefficient products. Renewal and reconstruction of old equipment, focusing on high power-consuming small and medium-sized motors and fans, pumps system renewal and reconstruction and fixed-flow system of reasonable matching.
2, improve the efficiency of the motor system
Promote frequency conversion speed control, permanent magnet speed control and other advanced motor speed control technology, improve the fan, pump motor system regulation, and gradually phase out the gates, valves and other mechanical throttling regulation. Focus on large and medium-sized variable operating conditions of the motor system speed transformation, reasonable matching motor system, to eliminate the "big marat car" phenomenon.
3, the drag device control and equipment modification
