Exports of parts and components should be strictly controlled

In the first quarter of 2014, the output value of automobile manufacturing industry in Xiaoshan District of Hangzhou City, Zhejiang Province reached 5.167 billion yuan, among which there were also enterprises involved in export. However, since 2013, the export of auto parts in Xiaoshan District has frequently been troubled by return shipments, accounting for 63% of the shipments of electromechanical products in the same period in the region. What is the reason for this?

In 2014 and the first quarter of this year, Xiaoshan Wanxiang Import & Export Co., Ltd. will purchase 4 parts of shipments, which have already received 4 shipments, amounting to USD 119,000. Xiaoshan Inspection and Quarantine Bureau began a retroactive investigation of this return. After preliminary investigation, it was found that there were no other obvious discrepancies in this series of goods except for slight surface defects.

Where is the problem? Xiaoshan Inspection and Quarantine Department sent experienced inspectors to the company and related personnel to carry out further analysis and investigation, and finally found out the real reason for the return: First, the material does not meet the requirements; Second, the product size does not meet the requirements, resulting in unable to install. There is also the test equipment is not effectively corrected, resulting in bulk returns. In the end, with the help of the inspection and quarantine department, the quality of the products purchased by the company remained stable.

Our district is plagued by the export of automobile and parts exports, and it is not only this company. According to statistics, during the period from 2013 to the first half of 2014, a total of 46 batches of automobile parts were returned in Xiaoshan District, which accounted for 63% of the batches of mechanical and electrical products shipped in the same period in our region. The total amount involved in shipment was US$ 1.034 million. The returned products mainly include hub units, bearings, brake friction plates and drive shafts. The returned countries are mainly Europe and the United States.

The inspection and quarantine department introduced the reasons for the return. The main reason is that the product does not meet the latest standards of the importing country, the production process defects cause the performance does not meet the buyer's requirements, product size does not match, the surface rust, glitches, etc. the Lord. In fact, there are many auto parts manufacturers in our district. However, auto parts products are not under the legal inspection catalogue of the inspection and quarantine department, and there is usually relatively little sampling of such products. Some manufacturers know very little about the content of foreign technical standards, which greatly increases the risk of export goods being returned.

“At present, more and more auto parts export companies are actively seeking assistance and urgently need to understand the foreign technical regulations, standards and conformity assessment procedures in order to break foreign technical barriers and enhance the market competitiveness of products.” The above-mentioned sources told reporters For this purpose, they are also seeking relevant countermeasures.

"On the one hand, we will actively establish an early warning mechanism for technical trade barriers, collect technical information related to major exporting countries and regions, such as technical regulations, technical standards, conformity assessment procedures, and label labels, and promptly notify exporting companies." On the one hand, according to the characteristics of returning more parts of Xiaoshan auto parts, it actively seeks funds, and carries out supervision and random inspection on the auto parts industry outside the legal inspection list. “Sampling plans and plans have been drawn up to lay the foundation for a comprehensive understanding of the quality of Xiaoshan’s export auto parts.”

Used in chemical reactor

The reducer is the most component of the reactor, and it plays very important role in producing the reactor. How we choose the suitable reducer for reactor?

1.      Cycloidal reducer: It had types of BLB11, BLB12, BLB13, BLB14, BLB15 and BLB16, which separately matches the relevant reactor. The speed of reducer ranges from 35r/min, 63r/min, 87r/min, to 130r/min. The different ratio of reducer match the different stir form of reactor. For example: the speed of 63r/min is generally used for sticky material and selecting frame reactor agitator. The speed of 85r/min is suitable for medium thick and anchor reactor kettle. The material is water aqua and paddle reactor at the speed of 130r/min.

2.      Special or very sticky material often chooses worm speed reducer and Helical bevel speed reducer, which is now widely used in industry. The two types of reducer has big torque and goof fatigue resistance. It is more energy-saving than cycloidal reducer. Worm speed reducer and bevel reducer is more suitable for very sticky material, but it is more expensive.

3.      The frame of reactor fitting for above reducer includes normal output axle and DJ type, DJ type is especially good in use, because it has reliable support, high precision on processing of reactor agitator. This point will make the mechanical seal of reactor more smooth, make the leakproofness of reactor better.
