This series of coordinate measuring instruments has the characteristics of powerful functions, stable performance, high accuracy, simple operation, and easy maintenance.

Compared with other product series, this series has the characteristics of simple structure, strong load-bearing capacity, spacious workpiece placement space, and convenient loading and unloading.

Coordinate Measuring Instrument/Coordinate Measuring Machine/Coordinate Measuring Machine:
The three-axis guide rails of the coordinate measuring instrument are made of high-quality granite material, which has the same temperature characteristics and therefore has good temperature stability, resistance to aging deformation, good rigidity, and minimal geometric deformation.

Adopting high-precision air bearings and a wrap around bearing layout design improves the rigidity and stability of the machine. Even after long-term operation, it can maintain high precision while ensuring excellent dynamic characteristics of the machine.

The unique Z-axis anti torsion design is an important factor in determining the accuracy of the measuring machine, and a reliable anti rotation structure design can achieve high accuracy even when using a probe extension rod. The application of a unique
nonlinear spring system reduces the impact of small errors in the guide rail on measurement accuracy, while ensuring that the equipment has higher environmental temperature adaptability.

The three-axis adopts high-performance synchronous belt transmission, which can not only achieve high motion speed to improve measurement efficiency, but also minimize transmission inertia to increase motion acceleration.

The crossbeam adopts a unique guide rail structure triangle, ensuring the maximum guiding air bearing span under the condition of minimum inertia, greatly improving the anti rotation accuracy of the guide rail. The length measurement system adopts the British RENISHAW high-precision reflective metal strip grating ruler and reading head, which has extremely high accuracy and accuracy stability.

SMC high-precision air filters can achieve extremely high cleanliness of compressed air to effectively protect air bearings and guide rails, while the automatic drainage device makes it more worry free and effortless for operators to use.

A comprehensive safety protection device can lock the three-axis in a timely manner in case of accidents, avoiding larger accidents and protecting the safety of the machine. The overall design conforms to the principles of ergonomics, is simple and convenient to use, and is easy to maintain and upkeep.

2. Frequency Conversion Control Technology of the Refrigeration System: In the frequency conversion refrigeration system, even if the power supply frequency of 50Hz is fixed, the frequency can be changed through the frequency converter, thereby adjusting the rotational speed of the compressor, and making the cooling capacity change continuously. This ensures that the operating load of the compressor matches the actual load inside the test chamber (that is, when the temperature inside the test body rises, the frequency of the compressor increases to enhance the cooling capacity; conversely, when the temperature drops, the frequency of the compressor decreases to reduce the cooling capacity). This greatly saves unnecessary losses during operation and achieves the goal of energy conservation. At the beginning of the operation of the test chamber, the frequency of the compressor can also be increased to enhance the capacity of the refrigeration system and achieve the purpose of rapid cooling. The test chamber adopts a frequency conversion refrigeration system, which can accurately control the temperature inside the chamber, keep the temperature inside the chamber constant with small temperature fluctuations. At the same time, it can also ensure the stable suction and discharge pressures of the refrigeration system, making the operation of the compressor more stable and reliable. Electronic Expansion Flow Servo.

Refrigeration system technology and other energy-saving technologies
1. VRF technology based on the principle of PID + PWM (the electronic expansion valve controls the refrigerant flow according to the thermal energy working conditions) is adopted. The VRF technology based on the principle of PID + PWM (refrigerant flow control) enables energy-saving operation at low temperatures (the electronic expansion valve controls the refrigerant flow servo according to the thermal energy working conditions). In the low-temperature working state, the heater does not participate in the operation. By adjusting the refrigerant flow and direction through PID + PWM, and regulating the three-way flow of the refrigeration pipeline, the cold bypass pipeline, and the hot bypass pipeline, the temperature of the working chamber can be automatically kept constant. In this way, under low-temperature working conditions, the temperature of the working chamber can be automatically stabilized, and the energy consumption can be reduced by 30%. This technology is based on the ETS system electronic expansion valve of the Danish company Dan-foss and can be applied to adjust the refrigeration capacity according to different requirements for refrigeration capacity. That is, it can realize the adjustment of the refrigeration capacity of the compressor when different cooling rate requirements are met.

2. The technology of grouped design of two sets of compressors (large and small) can automatically start and stop according to the load working conditions (large series design). The refrigeration unit is configured with a binary cascade refrigeration system composed of a set of semi-hermetic compressors and a set of fully hermetic single-stage refrigeration systems. The purpose of the configuration is to intelligently start different compressor units according to the load working conditions inside the chamber and the requirements for the cooling rate, so as to achieve the best matching between the refrigeration capacity working conditions inside the chamber and the output power of the compressor. In this way, the compressor can operate in the best working condition range, which can extend the service life of the compressor. More importantly, compared with the traditional design of a single large set, the energy-saving effect is very obvious, and it can reach more than 30% (cooperating with the VRF technology during short-time constant temperature control).

Refrigeration circuit technology

The electrical components shall be installed according to the power distribution assembly drawings issued by the Technology Department during the power distribution layout operation.

Internationally renowned brands shall be selected: Omron, Sch-neider, and German Phoenix terminal blocks.

The wire codes shall be clearly marked. A time-honored domestic brand (Pearl River Cable) shall be selected to ensure the quality of the wires. For the control circuit, the minimum size of the selected wire is 0.75 square millimeter RV soft copper wire. For all main loads such as the motor compressor, the wire diameter shall be selected in accordance with the safety current standard for wiring in the EC wire trough.
The cable openings of the compressor terminal box shall be treated with sealant to prevent the terminals in the terminal box from short-circuiting due to frosting.

All the fixing screws of the terminals shall be tightened with the standard fixing torque to ensure reliable fastening and prevent potential hazards such as loosening and arcing.

Refrigeration series process
1. Standardization

1.1 Standardization of the piping process and welding of high-quality steel pipes; The piping layout shall be carried out in accordance with the standards to ensure the stable and reliable operation of the machine model system.

1.2 The steel pipes are bent in one piece by an imported Italian pipe bender, which greatly reduces the number of welding points and the internal pipe oxides generated during welding, and improves the reliability of the system!

2. Pipe Shock Absorption and Support

2.1 MENTEK has strict requirements for the shock absorption and support of the refrigeration copper pipes. Taking full account of the shock absorption situation of the pipes, circular arc bends are added to the refrigeration pipes, and special nylon fixing clamps are used for installation. This avoids the pipe deformation and leakage caused by circular vibration and temperature changes, and improves the reliability of the entire refrigeration system.

2.2 Oxidation-free Welding Process As is well known, the cleanliness inside the pipes of the refrigeration system is directly related to the efficiency and service life of the refrigeration system. MENTEK adopts standardized gas-filled welding operation to avoid a large amount of oxide contamination generated inside the pipes during welding.
