Summary

Automatic running process

1.The gas enters the piston cylinder through the flow regulating valve FV and the explosion-proof three-way valve 
   DV1.

2.The motor pushes the piston to return the gas through the return port to achieve replacement.

3.Then pump the gas into the piston cylinder through the flow regulating valve FV and the explosion-proof three-
   way valve DV1.

4.The explosion-proof three-way valve DV2 is electrically connected to the sampling cylinder mouth and the gas in 
   the piston cylinder is pushed out uniformly into the sampling cylinder, and the motor stops when the single 
   sampling amount is reached.

5.DV2 is switched to conduct with the return port, and the motor returns the excess gas in the piston cylinder to 
   the pipeline.

6.Turn off the DV1 and DV2 devices and enter the standby state, waiting for the next sampling time to arrive and 
   restart.

Performance characteristics

1.High-precision servo-controlled plunger pump for precise flow control.

2.The device can freely set a single sampling amount and pressure, sampling interval and sampling times.

3.High-precision pressure transmitter for real-time monitoring and recording during sampling.

4.The electronic control unit records the flow and pressure in real time, real-time monitoring of the actual 
   volume and accurate quantification.

5.Fully automatic completion and one-button operation.

Technical Parameters

Device operation process

1.Connect the sample cylinder to the device and turn on the power of electronic control unit.

2.Set a single sampling volume and pressure, time interval between two samples, total sampling times and other parameters.

3.Start the run button, the device enters the automatic running state and performs cumulative sampling.

4.FV is opened, the explosion-proof electric three-way valve DV1 is rotated to the injection, the explosion-proof servo motor drives the piston movement through the screw  rod and the sample gas is pumped into the high-pressure cylinder at a constant speed. After the high-pressure cylinder is full, the motor stops.

5.The explosion-proof electric three-way valve DV1 is rotated to the sample, and the explosion-proof electric three-way valve DV2 is rotated to the cycle. The explosion-proof servo motor drives the piston movement through the screw rod, pushes the sample gas in the high-pressure cylinder at a constant speed and returns to the process pipeline through the return line to perform replacement.

6.After replacing 2 times, repeat step 4 to fill the high pressure cylinder with sample gas.

7.Explosion-proof electric three-way valve DV1 is rotated to sample out, the explosion-proof electric three-way valve DV2 is rotated to sampling, the explosion-proof servo motor drives the piston to move at a constant speed through the screw rod, and the pressure change value during sampling is recorded by the pressure transmitter P1 and is sent to the electric control CPU, in conjunction with the volume change of the piston movement, the CPU calculates the real-time actual volume. When the actual volume reaches our preset value, the motor stops running.

8.The explosion-proof electric three-way valve DV2 is rotated to the cycle, and the explosion-proof servo motor drives the piston to continue moving through the screw rod, pushing all the gas in the high-pressure cylinder back to the process pipeline.

9.Turn off DV1 and DV2, the device enters the standby state, waiting for the next sampling time to arrive and restart.

10.When the set number of times is completed, the device enters the completion state and is no longer timed.

11.The operators remove the sampling cylinder and close the device.

Note: Steps 4-10 in the process are completed automatically, and the operator does not need to operate any device.
