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.

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.

Some FAQs for worm gear speed reducer

Worm gear speed reducer is a compact, with big transmission ratio and with self-locking function.
A general problems for this are high temperature and oil spills and worm bearing damage.
Then solving these problems, how do we want it? Next we come to analyze.
1. Selection of lubricants and additives. Worm gear reducer 220 # gear oil is generally used for heavy, frequent starting, the bad environment, which can use some lubricant additives. so when you stop running gears, oil is still attached to the gear surface, forming a protective film to prevent direct contact between the metal heavy load, low speed, high torque and starts.
2. The establishment of lubrication maintenance system. According lubrication "five" Principles of gear maintenance, so that each person has a responsibility to gear regularly checked and found significant temperature exceeds 40 ℃ or oil temperature exceed 80 ℃, the quality of oil drops or oil We found more copper and produce abnormal noise and other phenomena, should immediately stop using and timely maintenance, troubleshooting, replacement of oil. When refueling, pay attention to oil, to ensure correct lubrication gear.

3. To ensure assembly quality. Can be purchased or made at a number of special tools to remove and install gear parts, try to avoid tapping with a hammer and other tools; change gear, when worm, try to use original parts and be replaced in pairs; assembly output shaft, pay attention tolerances; to use anti-adhesive or red lead oil to protect the hollow shaft, with the area to prevent rust or dirt wear, difficult disassembly maintenance.
4. Select reducer installed. Lower position permitting, try not to use vertical installation. When installed vertically installed a lot more than the amount of the lubricating oil level, could easily lead to fever reducer and oil spills.
