The cast iron motor test bench is mainly used for power experiments of mechanical motor engines and has good plane stability and toughness. There are grooves and bolt holes on the surface, which can be used to fix experimental equipment.
Two Cast Iron Motor Test Bench The motor test platform is made of high-quality high-strength gray cast iron. The hardness of the working surface is ℃. After two manual annealings, the internal stress is completely removed. This product has stable accuracy and good wear resistance.
Three cast iron motor test benches. Motor test platforms with specifications larger than this specification can be spliced to manufacture special-shaped specifications and can be customized according to drawings.
The accuracy of the four cast iron motor test benches is carried out in accordance with the national standard metrology verification regulations. It can be processed into grade-level fine planing according to customer requirements.
Five cast iron motor test benches. The surface treatment of the motor test bench is machine tool-processed grooves, which can also be provided with bolt holes. The surface is manually scraped to ensure plane accuracy. Remove the molding sand from the non-processed surface and apply anti-rust paint.
Six cast iron motor test benches. The motor test bench style is stiffened plate type.
Seven cast iron motor test bench motor test bench packaging wooden packaging. Anti-rust treatment and proper packaging before packaging to avoid damage to the product during transportation due to poor packaging. After the cast iron flat plate passes the test, it should be accompanied by a product certificate. The product certificate should have the date of manufacture and the product serial number.
Eight Cast Iron Motor Test Benches Motor Test Platform Technical Requirements
The working surface of the motor test platform shall not have defects such as sand holes, pores, cracks, slag inclusions, shrinkage, looseness, scratches, bumps, rust spots, etc. that seriously affect the appearance and performance.
The casting surface of the motor test platform should be clean of molding sand, smooth and firmly painted.
On the flat working surface where the accuracy of the motor test platform is registered as grade 1, sand holes smaller in diameter are allowed to be plugged with the same material, and their hardness should be smaller than the hardness of the surrounding materials. There should be no more than one sand hole blocked on the working surface, and the distance between the sand holes should be no less than 1.
The motor test platform should be made of high-quality, fine-grained gray cast iron or alloy, and its working surface hardness should be B.
The working surface of the motor test platform should usually adopt a scraping process. For the grade flat working surface processed by scraping, the maximum allowable value of surface roughness R is.
The flatness tolerance of the working surface of the motor test platform is specified in the table.
If the working surface of the motor test platform adopts scraping process, it should be painted and inspected. The ratio of the area of contact points displayed after grinding is specified in the table, or the number of contact points according to the square area is specified in the table, and the number of contact points in any one should not be larger than 10 points
