Non-sparking explosion-proof motors refer to machines that provide energy by consuming electrical energy. Because of the simple and reliable structure of sparkless explosion-proof motors, coupled with low price, it has been widely used in foreign petrochemical industries. After China adopted the IEC standard, non-sparking explosion-proof motors began to appear, and gradually became familiar to people.
Because of the simple and reliable structure of sparkless explosion-proof motors, coupled with low price, it has been widely used in foreign petrochemical industries. After China adopted the IEC standard, non-sparking explosion-proof motors began to appear, and gradually became familiar to people. In order to adapt to the rapid development of the petrochemical industry and the increasing technology exchange and equipment introduction at home and abroad, the significance and prospect of the application of non-sparking motors are briefly introduced.
Type editing
There are many types of explosion-proof motors, such as flameproof, positive pressure, increased safety, and non-sparking types. In accordance with the provisions of Article 25.3 of the national standard GB50058-92, flameproof and positive pressure types can be used in Zone 1 hazardous environments. Increased safety can be used in Zone 1 or Zone 2 hazardous environments. Non-sparking types can be used in Zone 2 hazardous environments.
(1) Explosion-proof and positive-pressure explosion-proof motors have a complex structure, and their prices are more than double that of ordinary motors, and they require a higher level of technology and management during maintenance. Therefore, except for applications in hazardous environments in Zone 1 In addition, other hazardous environments should not use or minimize the use of such motors.
(2) Because the design temperature rise of the explosion-proof motor is 10 ° C lower than that of the ordinary motor, the volume is larger and the consumable materials are increased. The cost is also close to the flameproof motor. In addition, this type of motor has stricter special protection for relays. Requirements, so this type of motor is not generally used.
(3) The structure of non-sparking explosion-proof motors is roughly the same as that of ordinary motors, except that the protection level of the enclosure and the structure of the junction box are relatively high. In addition, some reliability measures have been added to the manufacturing process conditions, so its reliability is relatively high. High, its price is the lowest among all types of explosion-proof motors, only slightly higher than ordinary motors. Maintenance is also as simple as ordinary motors, so it can be widely used in Zone 2 dangerous environments [1].
Scope of editing
(1) Judging from the nature and characteristics of the production of explosive hazardous devices, the hazardous environment in Zone 1 in most petrochemical plants is very small, accounting for less than 10% of the total dangerous environment; the hazardous environment in Zone 2 accounts for more than 90%, especially After the petrochemical production facilities are widely adopted in the open or semi-open air layout, the dangerous environment in Zone 1 is reduced. In this case, if explosion-proof and positive-pressure motors are used only in the hazardous environment of Zone 1, the number will be very limited, and management and maintenance can focus on technical forces to ensure their reliability. In the dangerous environment of Zone 2, if the non-spark type explosion-proof motor is widely used, it will not only bring great economic benefits and convenient management and maintenance, but also be safe and reliable.
(2) Explosion-proof electric motors have good reliability in the dangerous environment of Zone 2, but they are expensive and it is easy to lose the explosion-proof performance after maintenance. This is a practical problem in use. If explosion-proof motors are only used in Zone 1 hazardous environments, this problem will be easier to solve because their number is very limited. In various types of explosion-hazardous environments, especially in a large number of Zone 2 environments, it has not been advisable to use explosion-proof motors indiscriminately and uniformly. This will not only increase the investment significantly, but also cause trouble to production and maintenance. [2]
Applicable conditions
(1) With the advancement of science and technology, especially after the highly automated measures such as computer control (DCS) are widely used in petrochemical production equipment, the reliability of production equipment is stable and stable, and the reliability of long-term production is greatly improved. The danger is also greatly reduced.
(2) Modern petrochemical production facilities generally implement open-air or semi-open-air layouts and use of dangerous gas monitors, which also effectively reduces the category of hazardous environments and reduces the possibility of explosion hazards, making Zone 2 The chance of an explosion hazard in the environment is greatly reduced.
(3) The improvement of the level of motor manufacturing, especially the use of new technology and new materials (such as low-voltage motors with F-level insulation) and strict selection of high-quality bearings, can greatly reduce the electrical accident rate and mechanical accident rate of the motor, which is non-spark Explosion-proof electric motors provide the possibility and guarantee for the wide application in the dangerous environment of Zone 2.
(4) Extensive use of emergency diesel in petrochemical production facilities
Generator power also improves the safety of hazardous environments in Zone 2. Because the main purpose of using the emergency power supply is two. One is to use the power necessary to ensure the production equipment to stop safely and smoothly according to the program after the normal power supply suddenly stops. Electricity. The second is to use the power required for the production unit to start up quickly after the normal power supply is restored and reach the normal production state, such as the power consumption of the equipment's insulation system and sealing system.
Editing of reliability design measures
(1) To prevent the motor from running out of phase, an automatic switch is used instead of a fuse for short-circuit protection of the motor. A thermal relay with the ability to prevent running out of phase is selected for motor overload protection.
(2) When selecting a high-voltage large and medium-sized non-sparking motor, the manufacturer may be required to install a temperature measuring device on the motor stator coil to monitor its operating temperature.
(3) The production facilities are widely used in open or semi-open air layouts, and dangerous gas alarms are installed to reduce the accumulation of dangerous gases and detect the leakage of dangerous gases early.
Instructions for use
Difficulties in adopting non-spark type explosion-proof electric motors in dangerous environment in zone 2 and measures to be taken.
(1) In engineering design, motors are mainly selected by professional designers in chemical industry and equipment. This is because motors are auxiliary equipment used with pumps. Designers mostly focus on the performance and selection of pumps, and do not pay much attention to the selection of supporting motors. In addition, designers are not very familiar with the division of hazardous environments, the type and use range of explosion-proof motors, and the idea of high or low, so in the design scheme, explosion-proof motors are always used in hazardous environments.
(2) Due to customary and institutional reasons, especially under the intervention of construction unit personnel, engineering designers are often reluctant to adopt non-spark explosion-proof motors.
(3) The higher-level department requires the explosion-proof electric motors of the pump and pump manufacturers, which are generally non-spark type explosion-proof electric motors. In addition, other types of explosion-proof electric motors can be matched according to user requirements
Non-sparking explosion-proof motors are motors that do not extinguish explosive mixtures around them under the premise of abnormal operation, and also do not cause extinguishment problems. Compared with the increased-safety motor, except for the insulation dielectric strength test voltage, winding temperature rise, te (exchange winding after reaching the extra operating ultimate temperature at the highest temperature, it starts from the beginning and rises to the limit through the starting current. Temperature time) and starting current ratio are not specifically defined like the increased safety type, and the rest is the same as the planned request for the increased safety motor. Non-sparking explosion-proof motors are in accordance with GB 383.6-83 and GB 383.68.8-87, "Explosion-proof electrical equipment for explosive situations, non-sparking electrical equipment" n "". The plan pays attention to the sealing step of the motor. The main body protection grade is IP54, IP55, and the junction box is IP55. For motors with an extra voltage of 660V or more, the space heater or other connecting pieces to help assembly should be placed in a separate junction box. The YW series non-sparking explosion-proof motor products have been developed and extended at home (the middle height of the base is 80 ~ 315mm). The explosion-proof mark is nIIT3, and it is suitable for the 2 zone occasions where the workshop contains a flammable gas or vapor and an explosive mixture composed of atmosphere and temperature group T1-T3. The extra frequency is 50Hz and the extra voltage is 380, 660, 380 / 660V. The motor adopts F insulation, but according to the B-level audit of the temperature rise limit of the stator winding, it has a large margin of temperature rise and high safety reliability. The power is 0.55 ~ 200kW.
