Knapsack manual sprayer

The sprayer is a pesticide sprayer used to control plant diseases, pests and weeds. It is also widely used in sanitation, epidemic prevention, disinfection and sterilization, and has played an important role in this year's anti-SARS disinfection process. China is a large agricultural country with a large variety of crops, large planting area, and small scale of agricultural production. The demand for sprayers is very large. According to incomplete statistics, the social possession of sprayers in China is around 60 million units, and the annual sales volume is around 10 million units. Knapsack type manual sprayer has the advantages of light weight, simple structure, low price, convenient carrying and operation, and is very popular with users. At present, the quality of knapsack sprayers varies widely. Some manufacturers (especially those of the former shop and the factory) are driven by profits. They use counterfeit materials and shoddy methods to manufacture counterfeit and inferior products. They compete at low prices, flood the market, and users purchase products. Pay attention to the following questions:

1. Is there any mandatory product certification (3C) on the product?

Mandatory product certification is the mandatory testing and review of products listed in the Catalogue through the development of compulsory product certification product catalogs and the implementation of mandatory product certification procedures. All products listed in the 3C catalogue have not been certified by the designated certification body, and no certification mark has been added in accordance with the regulations. They must not be imported, sold in factories, or used in business service establishments. The compulsory product certification system was formally announced before China's accession to the WTO on December 3, 2001. The starting date for law enforcement oversight was August 1, 2003. The knapsack plant protection machinery was included in the first mandatory product catalogue. This means that the quality of knapsack sprayers that have not passed 3C certification is not effectively controlled. Sales on the market since August 1, 2003 are not in compliance with the national compulsory product certification system. See if the product has the 3C logo and do not purchase products that have not passed the 3C certification.

2. The relevant documents of the product are not complete

Relevant documents should include product certifications, product specifications, warranty documents (warranty cards), etc. Each product should be equipped with a set of documents. When the user purchases, it depends on whether the document is complete, whether the company name, address, contact telephone number, and zip code are included in the product specification and the three-package certificate, and whether the product name and model are the same as the product. The validity period of the three-package voucher is the three-package requirement issued by the six ministries and commissions of the country (plant protection machinery is not less than one year).

3, product appearance

The appearance of the sprayer's medicine box should be colorful, consistent in color and uniform in wall thickness. If the surface is rough, the color is dull, and the wall thickness is not uniform, it is often processed with recycled waste plastics. This kind of medicine box has low strength, poor toughness, and pressure resistance. Poor sex, in the process of use, prone to damage to the medicine box, popping tube burst and other issues.

4, product logo

Products should be marked, and should be marked with product trademarks, model specifications, business names, etc., and these contents should be consistent with the contents of the product manual, warranty certificate (warranty card) and other documents.

The permanent safety warning signs that meet the requirements of the standard shall be affixed to the parts that are likely to cause danger.

5, product assembly quality

Check whether the fasteners are installed firmly, whether the movement of the moving parts is flexible, whether there is stuck phenomenon, whether the rigidity of the handle is sufficient, whether there is deformation and bending phenomenon when the force is applied, and whether the valve and the connecting parts are leaking during the pressurization.

6, random spare parts

Check the packing list (or instruction manual) for the spare parts, whether the type and quantity of the spare parts are the same as those specified.

7, simple test spray quality

When the user purchases, it is best to do a simple test on the sprayer, that is, add clean water to the medicine box, spray it after pressing, check the atomization effect of the sprayer, and the fine mist of the sprayed medicine sprayed by the sprayer with good performance is uniform, and the mist is small and no Dripping phenomenon, valve and connecting parts should be no "run, run, drip, leak" phenomenon.
