Feeder quality appraisal

Feeder, also called feeder, is an automated mechanical equipment used in industrial production. It can automatically feed materials into other mechanical equipment, such as mixers, crushers, packaging machines, etc., to accurately measure and transport materials.
feeder is widely used in chemical industry, food, medicine, metallurgy, building materials, petrochemical and other industrial fields, and is suitable for conveying solid particles, granular materials and powdery materials.
Zhongke Testing and Appraisal Institute can provide quality appraisal services for manual feeders, semi-automatic feeders, unit automatic feeders and other feeders, and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

(1) According to the degree of automation, it can be divided into manual feeders, semi-automatic feeders, unit automatic feeders, and feed bag feeding combination automatic machines.
(2) According to the machine structure, there are single-row feeders, multi-row feeders, and vertical rotating feeders.
(3) can be divided into liquid level constant pressure feeding, liquid level variable pressure feeding, vacuum feeding, mechanical pressure feeding and pneumatic feeding according to the feeding method.
(4) According to the feed switch, there are three types of feed: plug type, valve type, slide valve type and air valve type.
(5) has 1-48 feeders depending on the number of feed heads. According to quantitative feeding,
(6) can be divided into quantitative measurement in movable quantitative cylinders, quantitative measurement in fixed quantitative cylinders, quantitative measurement in controlling the feeding liquid level and position to determine the amount of fish, and quantitative measurement in quantitative pumps.
(7) According to the characteristics of feeding, there are liquid feeders, sauce feeders and solid feeders.

An engineering equipment company signed a "Product Purchase and Sales Contract" with a technology company and purchased 6 feeding metering systems from it. After receiving the goods, it was discovered that the feeder had quality problems and was returned to a technology company for rectification. However, the company has been unable to deliver qualified products to an engineering equipment company. Therefore, an engineering equipment company appealed to the court.
Our company was entrusted by the court to undertake the quality analysis of the "feeder" involved in this case.
identification and analysis results: The
quality analysis expert group conducted a discussion and comprehensive technical analysis on the relevant information, on-site investigation and inspection conditions, and inspection and testing data of the "feeder" involved in the case, and made the following quality analysis opinions:
involved in the case " The entire frame of the "feeder machine" does not use stainless steel materials that are not in contact with the raw materials. The weighing sensor does not use the HBM brand. There is no positioning pin at the connection between the screw double-brace tube and the hopper. The sealing of the outer bearing cover of the unloading port is poor. The material is stuck in the hopper. Five of the feeding motors do not use TECO variable frequency motors. None of the above are in compliance with the relevant provisions of the contract and technical agreement.
