Double glass reactor step
1. After opening the package, check whether the main accessories of the machine are complete according to the packing list.
2. Assemble the frame in accordance with the drawings as shown in the figure.
3. Install the electrical box on the top of the right rear pole and tighten the screws and insert the seven-pin plug. Install the vacuum gauge on the left rear end and tighten the screws.
4. According to the height of use, fix the round bracket of the kettle to the vertical pole slider, and place the kettle on the bracket. The semi-circular hoop is used to insert the vertical rod into the pole of the kettle, and then tighten the fixing screws after closing. Pay attention to the vertical direction of the reactor body during installation.
5. The stir bar is fixed on the ring clamp of the motor main shaft. The stir bar passes through the middle rotary bearing of the cover, tightens the special connector, and then adjusts the position of the motor, paying attention to the vertical concentricity.
6. The slider on the pole is a stainless steel multi-purpose clamp that adjusts the direction and height in different directions.
7. On the left side of the bottle cap, the 40# standard port plug-in type reflux condenser, the right side 40# is the feeding port connected to the constant pressure funnel, the middle front 24# port is the plug-in thermometer casing mouth, and the hat rear is the 34# standard port. It is a multi-functional spare port, and the bottom is provided with a discharge valve, and the bottom of the kettle body is respectively a circulating fluid inlet and outlet. The lower port is connected to the circulating fluid inlet, and the upper port is connected to the circulating fluid return port.
8. When installing the glass instrument, it must be cleaned, and the interface should be coated with Vaseline to prevent the glass from locking up, and then apply vacuum grease to prevent air leakage.
9. Press the universal wheel wheel fixing device to stir. If the stirring is stable, the debugging is good.
Double-layer glass reactor operation procedure
1. Check that the power supply voltage is consistent with the specifications provided on the machine nameplate.
2. Plug in the power plug, turn on the power switch on the inverter, and use the speed control knob to select the appropriate speed.
3. The flow of material and the power of the motor speed may resonate at a certain point. Please change the speed of the motor to avoid resonance.
4. After the stir bar is installed, it must be rotated by hand. Pay attention to whether the concentricity is good. If the heart is not good, the heavy clamp should be loosened. After the clamp is turned on, turn on the power and adjust gradually from slow to fast.
5, using the stir bar regulator, you can make the stirring leaves up and down 5cm as needed.
6. If the sealing performance of the kettle is found to be degraded, please check the rotary bearing in the agitator sleeve.
7. The glass equipment of the reactor is made of GG.17 low expansion coefficient high temperature resistant borosilicate glass. The user should self-fit glass bottles such as reaction bottles. Please confirm the glass material to ensure safe use.
8. The external layer of the interlayer on the glass kettle can be heated by the hot oil. The coolant can be used for low temperature reaction. If it is heated by steam, it should not exceed 0.5K-1K. (Try not to use pressure steam to heat).
9. When the double-layer glass reactor is tested at low temperature, the discharge valve at the bottom will be frosted. When using the valve, it must be partially thawed to prevent the glass from being broken.
10. If there are particulate objects in the solution during use, it is possible to store the remaining materials on the PTFE piston of the valve. When used again, the airtightness will be affected. Be sure to clean and re-use each time after discharging. .
Double-layer glass reactor maintenance
A. Check the instrument carefully before use. Whether the glass bottle is damaged or not, and whether the interfaces are consistent, pay attention to light handling.
B. Note that this equipment is a fragile product. Please be careful when using it. The damage of fragile products is not covered by our warranty. If the customer needs, we will charge the corresponding cost.
C. The PTFE switch in all places cannot be tightened too much and it is easy to damage the glass. 4. Turn on the power switch first, then let the machine run from slow to fast. When the machine is stopped, stop the machine and turn off the switch.
D. The interfaces should not be tightened too tightly. It should be loosened regularly to avoid the long-term tight lock and cause the connector to die.
E. Every time you use it, you must wipe off all kinds of oil stains, stains and solvents left on the surface of the machine with a soft cloth to keep it clean.
F. Clean the seal ring regularly by removing the seal ring and checking if there is dirt on the shaft. Wipe it with a soft cloth, then apply a little vacuum grease and reinstall it to keep the shaft and seal ring smooth.
G. Loosen the PTFE switches after stopping, and the PTFE piston will be deformed when it is still working for a long time.
H, the electrical part must not enter the water, it is strictly prohibited to get wet.
I. The original authentic accessories must be purchased. Any use of other accessories can cause fatal damage to the machine.
J. When doing any repairs or inspections on the machine, be sure to cut off the power supply and water source.
K. The instrument is returned to the manufacturer for maintenance once after three years of use (recommended).
L. Wipe each interface with a soft cloth (can be replaced with a napkin) and apply a small amount of vacuum grease. (The vacuum grease must be covered after use to prevent the entry of sand.)
