Purchased by customers Electronic Universal Testing Machine After the arrival of the goods, it must be installed and debugged, and then after confirming the correctness, sign for receipt. Therefore, the following points must be observed for the acceptance criteria of the electronic universal testing machine:
1. Appearance Requirements
1. The surface of the whole machine is clean, no dents, no rust. The sheet metal painting on the surface is complete and free of defects The TypeLabel on hull surface should include machine model, manufacturer's name and contact information.
2. The surface of the bracket is smooth and coated with anti-rust oil. Clamps should be brand new with no signs of wear on the jaws.
3. If there are accessories such as extensometers, computers, printers, etc., check the packaging integrity.
Second, whether it matches the configuration list Consistently
When a general manufacturer signs a contract of sale with a customer, he will There is a relatively detailed coconfiguration list, and customers can check the configuration of the instrument according to the list. In general, you need to focus on the following parts:
1、Sensor: The sensor plays an important role in the accuracy of the universal electronic testing machine. Its important role is that 0.5-level high-precision -Electronic universal testing machines generally use imported sensors. Imported sensors are widely used in the United States, Shiquan, Transli, Japan's Shimadzu, Germany's HBM, etc. Customers can pay attention to the brand of the sensor to prevent unscrupulous dealers' position change.
2, Servo motor: The servo motor is the power of the universal electronic testing machine, and the performance of the servo motor is very important for the universal electronic testing machine The accuracy and stability of the Testing machine play a crucial role. The 0.5-stage high-precision electronic universal testing machine uses more servo motors, most of which are Japanese Panasonic and Taiwan brand motors Delta motors are also used. The factory installer and debugger must open it at the time of acceptance. Check the make and model of the servo motor on the machine base.
3, Ballscrew: A high-quality ballscrew is also an important factor to ensure the accuracy of the electronic universal testing machineen , Since the screw is usually installed in the center of the column, it is not visible from the outside. The manufacturer may be requested to provide the ball screw manufacturer's manifest, technical standards and other information to facilitate the verification.
3. Full product description and assembly schematic
The electronic universal testing machine of the common manufacturers has detailed product descriptions and circuit diagrams that can be provided by the manufacturers.
