Smart Pumps: Helping Precise Vacuum and Pressure Environment Control in the Laboratory

Smart Pump

Hilin Technology ZC60 and ZD50 smart control air pumps are complete gas pump equipment developed by Hilin Technology for laboratory application scenarios. By integrating Hilin Technology’s long-life diaphragm pump counting, sensor technology, and pressure control technology, they provide laboratory users with A complete equipment that can control positive and negative air pressure and pumping speed with an accuracy of 0.5kPa in the range of -85kPa to +150kPa.

ZC60 and ZD50 laboratory air smart pumps have many important applications in laboratories, including the following aspects:

Application in chemical experiments:

Distillation and evaporation: Distillation and evaporation under low pressure conditions can lower the boiling point and thereby prevent the decomposition of heat-sensitive substances. ZC60 can reduce the temperature of liquid water to room temperature by creating a vacuum environment, and can set the distillation and evaporation time through time control to improve experimental efficiency.

Concentration under reduced pressure: By reducing the pressure, the evaporation of the solvent can be accelerated, thereby concentrating the sample. Consistent with distillation and evaporation, the experimental reagents are concentrated by creating a vacuum environment.

Vacuum drying: used to dry heat-sensitive and easily oxidized chemicals to prevent samples from being heated or oxidized, or to dry samples at low temperature through low-temperature freeze-drying.

Applications in physics experiments:

Gas research: Under low or high pressure conditions, the physical and chemical properties of gases will change. ZC60 and ZD50 laboratory intelligent air smart pumps can control the positive or negative pressure of the experimental environment to facilitate the study of gas properties, such as diffusion, adsorption and reaction, etc. .

Vacuum coating: thin films are deposited in a vacuum environment and used to prepare various optical and electronic materials.

Biological experiments:

Vacuum filtration: used to quickly filter solutions, using pressure difference to accelerate the speed of liquid or gas passing through the filter membrane, especially when the sample amount is large, it can improve the filtration efficiency.

Cell culture: Cell culture and processing are performed in a sterile environment to avoid contamination.

Materials Science Experiments:

Vacuum sintering: Sintering of metals and ceramics under vacuum conditions to reduce impurities and improve the purity of the material.

Material testing: Test the physical and chemical properties of materials under vacuum conditions, such as oxidation resistance and high temperature resistance.

Environmental Science Experiments:

Gas sampling: In environmental monitoring, it is used to collect samples from the atmosphere for analysis. ZC50 and ZD60 laboratory air smart pumps can adjust the sampling pressure, sampling rate, and sampling time to flexibly control the number of gas sampling experiment samples.

Pollutant analysis: Concentration and detection of trace pollutants through vacuum pumps.


Leak detector: By creating a negative pressure or positive pressure sealing environment with a specific pressure, tiny gas leaks can be accelerated, leaks can be discovered and sealing performance can be judged more accurately.

Mass spectrometer: Mass spectrometry analysis needs to be performed in a vacuum environment to ensure that ions can move freely and be accurately detected.

The use of ZC60 and ZD50 smart pumps to assist in various experiments not only improves the experimental efficiency, but also ensures the accuracy and reliability of the experimental results.

How do ZC60 and ZD50 laboratory smart air pumps accurately control vacuum and pressure? This is mainly achieved through the following methods and technologies:

Electromechanical control:

Frequency converter control: Use BLDC frequency converter to adjust the speed of the vacuum pump motor to achieve precise control of the flow rate.

Solenoid valve: By controlling the opening and closing of the solenoid valve, the air flow in and out can be accurately controlled to regulate system pressure.

Pressure buffer tank: Installing a vacuum/pressure buffer tank can balance pressure fluctuations in the system and maintain stable air pressure.

Feedback control system:

Pressure sensor: Install a pressure sensor in the vacuum system to monitor the vacuum degree and pressure value of the system in real time. The sensor feeds back the measured pressure value to the controller.

Controller (PID control): Use a PID (proportional-integral-derivative) controller to adjust the operating status of the vacuum pump (such as pump speed or valve opening) based on the pressure value fed back by the sensor and compare it with the set value to achieve accurate vacuum control.

Smart Pump Automatic Control System:

Closed-loop control: In the ZC60 and ZD50 smart pump systems, pressure measurement and regulation form a closed loop, and the Cortex microprocessor is used to automatically adjust the smart pump and valve to work together to keep the system within the set vacuum and pressure range.

Timing control: In the ZC60 and ZD50 systems, the working time of the smart pump can be set, and the working time of the entire test system can be controlled by starting and stopping the vacuum pump at scheduled times.
