High Efficient motor rapidly developed with policy support

With China's accession to WTO, the domestic motor industry faced enormous competitive pressures and challenges. Seeing from the international and domestic development trend, developing China's high-efficiency motors is necessary and it is also a market requirement. So that make our electric motor products keep up with the international trend,. According to statistics, in 2002 China accounted for more than 60% on the electrical motor power consumption of the country. And the power is about 35%, which is power-hungry.

three asynchronous motor

 

It is reported that China's industrial energy consumption accounts for 70% of total energy consumption, including electrical energy consumption accounts for 60% to 70% of industrial energy consumption, coupled with the non-energy industrial motors, motor actual energy of the total energy consumption more than 50%. Now low proportion of applications of energy efficient motors. According to the National Quality Supervision and Inspection Center of small motors for domestic motor 198 key enterprises sample survey, the proportion of energy efficient motors which reach more than 2 only 8%, which on the whole society had a tremendous waste of resources. Why efficient motor has not really enter the market? The higher prices, the market situation is not ideal, so that fewer manufacturers, resulting in user awareness of efficient motor is not enough, this is one of the main reasons. This year, the Ministry of Industry on March 26 issued the "2013 industrial energy efficiency and green development special action plan" put forward the notification, in 2013 will focus on promoting the implementation of special programs to enhance the energy efficiency of the motor. Target special action is: to achieve savings of 1% of the country's industrial electricity consumption (about 300 million degrees), to explore the pattern of industrial energy efficiency and green development and implementation of ways to achieve a point, and drive energy conservation and comprehensive utilization of overall industrial progress. According to an embodiment, in 2013 the Ministry will promote efficient motors, eliminating six aspects of the existing inefficient motors and motor systems and other aspects of energy-saving technological transformation, extension, elimination and energy-saving motors and motor systems 100 million kilowatts, expand market share high efficiency motor and promote the upgrading of electrical products and industrial upgrading. Thus, the government is to promote efficient motor, but needs to continue to increase promotional efforts. But in the current market economy, short-sighted companies are reducing their procurement costs, which is a high efficiency motor price become a contradiction. Therefore, the promotion of efficient motors also need politicians to improve the focus on efficiency, high efficiency motor conduction efficiency can quickly link to the downstream market in order to present the hugely popular scene.

Cycloid gear reducer, using cycloid tooth meshing is an advanced design, new style structure of the reduction way, which can be both clockwise and reverse operation. The biggest feature is that it has the high transmission efficiency and also a wide ratio transmission range. And power is available from 10KW to 50000kW. Otherwise, its size and weight is much smaller than helical gear reducer and worm reducer. However, its structure is more complex high precision. It is widely used in petrochemical deceleration devices, light industry, pharmaceutical industry, textile, metallurgy, mining, sewage treatment and construction machinery and other transmission machinery.

Belt reductor, speed redactor with belt, it is high efficiency, long life, compact structure, smooth transmission, easy removal and other features that allow positive and negative direction of running, in large fermentation devices more often.

Worm gears, worm gearbox with worm gear drive is mainly used for large occasions, with smooth contours and other transmission compact size advantages of small work, but less efficient single-stage worm reducer thus used more two-Worm reducer is seldom used. Range of single-stage worm gear transmission ratio is generally 10-70.

Gear reducer, it mainly gets cylindrical gear reducer and bevel gear reducer. cylindrical gear reducer which is the most widely using. which can deliver the power range from small to 4000kW peripheral speed is also available from low 60-70m/s; and the input shaft and output shaft position bevel gear reducer to 90o configuration making it suitable for input and output shaft perpendicular to each other occasions. The main features of the gear reducer is durable and easy to maintain high efficiency, according to the reduction gear stages can be divided into single-stage, two, three or even multi-level, avoiding gear outside dimensions too large, generally when the ratio of 8 The following can be used when a single-stage gear reducer, the best selection of two or more stages and it is greater than 8.

Introduction of The Rotary Feeder

Rotary feeder can be used as the bunker discharger in the material collecting system. Rotary feeder is the most advanced discharging device currently and commonly used as one of important equipment in dust removal system. It is particularly suited to dust, small granular materials and very popular in environmental protection, metallurgy, chemical industry, food, cement, building roads, drying equipment and other industries project.


The temperature of conveying material can reach 280℃. On both ends of bearing and impeller has a certain isolation, which can prevent the superfine powder contacting the bearing. Connected by sprocket, The temperature of conveying material for high temperature resistant type discharger can reach 500 . The cycloidal gear motor reducer and discharger shell has certain distance.

The Rotary feeder composition is made with the number of leaves, seals and motor reducer, motor rotor impeller, shell and so on. The star discharging device, also known as rotary feeder, lock valve, star discharge valve, the star feeder, rotary feeder. As a special kind of unloading equipment, Rotary feeder plays a large role in the cleaning and washing work, and it is necessary to summarize its characteristics. So we can make a better understanding of the rotary feeder to do comprehensive and maintenance.

K series gearmtor

K seires gearmotor is a right angle mounting way with helical-bevel gearing sets.  Industry Standard. Our dimensions of this gearmotor is exact same as SEW europedrive's. and aslo for the model number. So it is an ideal replacment for this famous brand. Quality is competitived but lower prices.

The helical-bevel gears gives a more efficiency than other types of gearing such as helical-worm types. Some clients often misunderstand these two type gears. Actually, they are much different. The helica-worm gearbox has a low effiency and right for some light industries. and the helical-bevel gears are higher price than the helical-worm type. Of course, in a suitable industry to choose a right model, this is the key.

Our K series gear reducers can be with motor in VFD or brake or both. In the gearhead, it also can be coupled with a torque arm, some calls Mounting plate. they are same. To provent the complete sets move and easy to operation. The complete sets with gearheads and motor, is in various mounting. Upper or  down or left or right. Almost for every usage industry.

Myanmar will permit Import of Second-hand machinery and equipment

According to local news in Myanmar on March 20, the Myanmar Commerce Department said, they will permit import of the used machinery and equipment from March of this year, in order to promote the development of Small and Medium-Sized Enterprises. Because of imported second-hand equipment is much more cheaper than the new one, to the businesses, buying used equipment can get greater profit margins and also can ease the financial pressure on SMEs. Commerce Department also said that in order to avoid becoming the focus of waste equipment developed markets, Myanmar imported second-hand equipment to strict import policy will be adjusted annually. Used equipment imported only allowed to be by sea through border trade imports. Prior to this, the Burmese do not have to allow imports of second-hand equipment.

Packaging machinery industry

Packaging machinery is widely used for food, pharmaceutical, printing and other industries, with raise of people’s consumption, it brings a huge space for development of the China's packaging machinery. As the needs of various industries for packaging machinery is rising year by year, China's packaging machinery has been unable to meet the needs of many industries. Domestic packaging machinery company should actively look for ways to be better-developed from the demand of industry.

At present, China's packaging machinery manufacturing skill levels diversified, weak capacity, development of competition in the market has not kept pace. Now, some packaging machinery companies have increased ability to innovate, and actively adjust the product structure, basically meet the market demand, but there are still some products relied on imports.

In recent years, as China's technological level and that the gap is growing, investment in research and development enterprises accounted for 1% of business sales, the business to survive, accounting for 2% can barely accounted for only 5% competitiveness, and investment in research and development for an average of less than 1%.
According to statistics, the national R & D expenditure accounted for only 0.3% to 0.5% of corporate sales, R & D personnel employed only 3.4% to 4%. Abroad, a serious shortage of investment in research and compared, resulting in a low degree of automation equipment industry, with an average of 4 to 6 times the energy consumption in developed countries, it is difficult to meet the market demand. More large equipment performance gap, advanced model is about 1/2 of the advanced level, the overall level of technology behind the developed countries about 20 years.

Powder drying mixer gear drive system

Each powder drying mixer will be mounted on a reducer at the top next to the motor, mostly due to the mixing shaft operating speed range is within 30-600rpm far less than the rated speed of the motor, needing to mount a gear reducer at the end output shaft of the motor, which is a independent closed power transmission gears between the AC motor and the working machine to reduce speed and increase torque accordingly.

In accordance with the driving and structural characteristics, it can be divided into cycloid reducers, belt pulley reducer, worm gear reducer and helical gear reducers, when we choose the right gear reducer according to process requirements and operating environments Optional machines, in addition to satisfying the selection of output power and speed requirements should be easy and reliable operation and maintenance of high mechanical efficiency and low noise. Now we come to recognize that these four were reducer, learning under their works.

R series gearmotor

As a widely used type power transmission drive, R series helical gearmotor plays very important role in industry manufacturing. 

All dimensions of our R serial gear speed reducers are same as SEW's R serieal. Which can be well coupled as a replacement, but much more cheaper. We have multiple kinds of mounting ways for this type, foot mounted, vertical mounted, flanged mounted, long shaft mounted, and others. The gears from two stages to four stages, which can make larger torques.

For the motor connected, It can be coupled with AC motor or DC motor.

For AC motors, Y2 series standard electromotor or YD two speed electric motor or other types motor.  IEC motor NEMA motor can be fit as well. In a word, we can change the flange of the inoput side of the gearbox to make well fit in the types of motor. 

For the DC motors, we usually connect with Z4 serial DC motor whose power from 0.05kw to 300KW. There are plenty of mounting ways, from top to bottom or left or right. It concerns about the oil leaking. So this is a important factor for customer to choose the right model.
