Product Overview


 

1. Energy saving: The technology is based on the PWM solenoid valve customized by Sporlan Company in the United States. This technology realizes the regulation of the pipeline flow through the frequent actions of the solenoid valve. The standard solenoid valve cannot adapt to it, and it will cause fatigue damage in a short time. Currently, this technology is supported. The main performance valve is only produced by Sporlan Company in the United States. The following picture shows the difference between the solenoid valves.

 

2. Performance: The equipment conforms to the latest standards, the equipment is integral, beautiful and easy to transport;The main parts of the equipment are selected from well-known brands at home and abroad. The fully enclosed and imported French "" compressor with higher precision and the Hangzhou "Yuanfang" variable frequency power supply with better stability make the precision control more accurate during the operation of the equipment. Noise Lower, more stable performance and longer service life;

 

3.Device control: The device can be connected to multiple devices, controlled by mobile phone APP, and controlled by advanced PLC, which is more intelligent and more convenient to operate. The true color touch screen displays various test data (temperature, time, test curve), which is easier to operate. observation records;

 

4.Measurement and control system: real-time and dynamic display of test process and test curve, data processing through modular software, data reanalysis and editing of curve amplification, output of test reports and curve patterns in different formats, and support for networked data transmission.

 

5. Professional, safe and user-friendly design: emergency stop control switch, in case of emergency, can lock equipment reliably; effectively protect equipment; multiple protection of software and hardware to ensure the safety of equipment and personnel.

Heating and cooling systems and how they work
 
Project Principle description
Heating system Stainless steel tube sleeve type anti-dry heating tube with built-in nickel-chromium alloy heating wire
U-shaped fin type stainless steel high-speed heating electric heater for heating
Completely independent system, does not affect the control line
Refrigeration system Cooling method Air-cooled
Refrigeration compressor Adopt imported Tecumseh compressor, use environmentally friendly refrigerant
Refrigerant copper tube Internal spiral K-TYPE refrigerant copper tube
Condenser Corrugated fin type air-cooled condenser
Evaporator Slope type FIN—TUBE evaporator
Freezing element Original imported solenoid valve, drying filter, etc.
Features The whole system pipelines are tested for leak detection by ventilating and pressurizing 22kg.
Heating and cooling systems are completely independent
Equipped with the company's professional technical characteristics, it can prevent the high temperature and high-pressure airflow from returning to the cooling machine and damage the system.
All refrigeration system action programs are completely controlled by microcomputer controller
 

Adjustment system

 

Project Specifications
Adjustment method

Forced circulation ventilation, balanced temperature regulation. The control system controls the output of the heater according to the temperature point set by the system through the result of PID automatic calculation output, and finally achieves a dynamic balance.

 

 

 

Circulation device The built-in air-conditioning room, circulating air duct and long axial flow fan improve the air flow and heating capacity by improving the agitation airflow of the air, and greatly improve the temperature uniformity of the test chamber.

 

Control system:

 

Project Illustrate
Controller 7-inch PLC LCD touch programmable controller
Touch high-definition screen The fixed conditions and program conditions can be set arbitrarily, the Chinese screen can be set, and the curing test name and serial number can be set.
Settable time range 0—999H59min.

Programmable mode

 

At the same time, 120 groups of programs with different conditions can be set. In any group of programs, the work can be divided into 1200 segments, and the number of segments can be arbitrarily intercepted to execute the cycle, or the periodic cycle of any segment or group can be performed.
In each group of programs, up to 1200 different temperature and time sections can be set (each section can be set up to 999h59min). 120 groups of programs can be connected in series at will, and the maximum number of sections can be cycled up to 999 times.
Safety With a power-off memory device, the remaining programs can continue to be executed when the power is restored, and the machine can be reserved to execute the start-up and machine running time.
Control Rising and cooling can be used for slope control and curve control, and has the function of self-correcting temperature and humidity reference points. It has the function of PID automatic calculation, which can reduce the convenience brought by manual setting.
Communication function U disk interface, RS-232 interface, mis operation hardware lock, random computer communication software
Set up Touch setting, direct display of position, all conditions are completely automatically locked by microcomputer
Alarm If there is an error in the setting or operation, a warning signal will be provided
Output The controller has a recording signal port output, which can be connected to a temperature and humidity recorder and output a recording curve
Interface With standard RS-232 communication interface, long transmission distance, can be connected to PC for control and recording.
