Intelligent automatic liquid nitrogen replenishment monitoring equipment, high-pressure liquid supply system

　　Intelligent automatic liquid nitrogen replenishment monitoring equipment, high-pressure liquid supply systemThe liquid nitrogen replenishment monitoring equipment is an efficient and intelligent device mainly used for low-temperature output of liquid nitrogen, achieving the purpose of cooling other equipment, or creating low-temperature/constant temperature environments, and monitoring terminal temperature and the overall process of tank replenishment.

Modular planning of liquid nitrogen monitoring equipment, with a liquid nitrogen tank for structural replenishment. The output pressure of the liquid nitrogen tank is confirmed based on customer requirements. The control part includes control, valve group, temperature/liquid level monitoring system. The liquid nitrogen replenishment monitoring equipment can implement 24-hour uninterrupted monitoring of replenishment and long-distance monitoring, with controllable terminal temperature. The liquid level in the liquid nitrogen tank is controllable. The overall operation process is controllable and can complete the proactive operation process.

The liquid nitrogen replenishment monitoring equipment can also be customized according to different customers to establish differentiated products. The size of the customer's terminal equipment, the temperature accuracy required by the customer's terminal equipment, the temperature accuracy scale required by the customer's terminal equipment, and the various requirements for automation in the application of the customer's terminal equipment do not affect the modular establishment of liquid nitrogen replenishment monitoring. Both small and large systems can be established to meet customer needs: temperature control accuracy, temperature control scale, liquid supply power, liquid supply pressure, unit time, cooling power, etc. can all be used as planning basis.

*Can be used with different types of liquid nitrogen tanks

The liquid nitrogen replenishment monitoring equipment can be matched with various products. As long as there is a demand for liquid nitrogen supply or cooling, the liquid nitrogen replenishment monitoring equipment can be used. The product is suitable for a wide range of pressure scales, temperature control scales, and high liquid supply power. The liquid supply end can be equipped with more liquid nitrogen tanks to complete the rotation of liquid supply, with a 24-hour uninterrupted liquid supply form.

Recommended types of liquid nitrogen replenishment tanks: self pressurized liquid nitrogen tank series YDZ-100, YDZ-150, YDZ-200, YDZ-230, YDZ-300

Product features and functions:

2、 Installation and usage instructions

Connect the liquid nitrogen delivery pipe attached to the liquid nitrogen supply tank firmly to the IN1 and IN2 interfaces of the control cabinet, and connect the OUT outlet to the terminal equipment.

Attention: Please make sure to tighten the joints at both ends of the liquid nitrogen infusion tube to prevent the occurrence of liquid nitrogen running, emitting, leaking, dripping, etc., in order to avoid the loss of liquid nitrogen and possible harm to the human body!

Attention: Please connect this device reliably to the ground to prevent electric shock accidents!

3、 Control software operation instructions

This system control software consists of six modules: initial screen, monitoring screen, system parameters, liquid level curve, pressure curve, and data export.

3.1 Initial Screen

The above figure shows the initial startup screen. Click on the corresponding dialog box to view the monitoring screen, system parameters, liquid level curve, pressure curve, and related data export.

3.2 Monitoring Screen

The monitoring module real-time monitors important data such as liquid level data, pressure data, system operation time, and the operating status of various solenoid valves in tanks A and B.

A tank liquid level: display real-time liquid level changes inside A tank;

B tank liquid level: display real-time liquid level changes inside B tank;

A tank pressure: display real-time pressure changes inside A tank;

B tank pressure: display real-time pressure changes inside B tank;

Running time: Record the duration of system control operation;

A-tank manual: When the system is shut down, the A-tank solenoid valve can be manually opened/closed, and the green light indicates that it is currently in the open state;

B tank manual: When the system is shut down, the B tank solenoid valve can be manually opened/closed, and the green light indicates that it is currently in the open state;

Drain valve: The main drain solenoid valve can be manually opened/closed in any state, and a green light indicates that it is currently in the open state;

Mute: When the system generates an alarm, manually release the alarm button;

A tank operation: Click on the system to automatically open the A tank solenoid valve (the current system liquid level is higher than the lower limit switching set value). When the A tank liquid level is lower than the set value, it will automatically close and open the B tank solenoid valve at the same time;

B tank operation: Click on the system to automatically open the B tank solenoid valve (the current system liquid level is higher than the lower limit switching set value). When the B tank liquid level is lower than the set value, it will automatically close and at the same time open the A tank solenoid valve;

Stop: System stop button;

3.3 System Parameters

Switching value for lower limit of liquid level in tank A: When the liquid level in tank A reaches the lower limit, it will automatically switch to using liquid in tank B and issue an alarm value (it is recommended to set it to 100);

Switching value for lower limit of liquid level in tank B: When the liquid level in tank B reaches the lower limit, it will automatically switch to using liquid in tank A and issue an alarm value (it is recommended to set it to 100);

A tank liquid level alarm release value: Set the A tank liquid level to trigger an alarm when it reaches the lower limit, and release the lower limit alarm when the liquid level reaches the specified height value after replenishing the refrigerant again (the set value must be greater than the lower limit alarm value);

B tank liquid level alarm release value: Set the B tank liquid level to trigger an alarm when it reaches the lower limit, and release the lower limit alarm when the liquid level reaches the specified height value after replenishing the refrigerant again (the set value must be greater than the lower limit alarm value).
