Double glass reactor maintenance instructions : 1. Check the instrument carefully before use, whether the glass bottle is damaged, whether the interfaces are consistent, and pay attention to it; 2. 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.) 3, each interface can not be tightened too tightly, it should be loosely activated at regular intervals to avoid long-term tight lock and cause the connector to bite; 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. 5, the PTFE switch everywhere can not be tightened too much, easy to damage the glass; 6, each time you use it, you must use a soft cloth to wipe all kinds of oil traces left on the surface of the machine, stains, solvent remaining, keep clean; 7. Loosen the PTFE switches after shutdown, and the PTFE piston will be deformed after being in a static state for a long time. 8. Regularly clean the sealing ring by removing the sealing 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. 9, the electrical part must not enter the water, it is strictly prohibited to damp; 10, must purchase the original authentic accessories, free use of other accessories can cause fatal damage to the machine; 11. When doing any repairs or inspections on the machine, be sure to cut off the power supply and water source. Note that this equipment is a fragile product, please be careful when using it.

Turn on the power switch and the indicator light does not light. The external power supply is not connected or the contact is bad. Please check the power supply and socket with a professional electrician; 2. Short-circuit the fuse tube, put the power switch in the OFF position, and replace the fuse tube; 3. The power indicator is on but not rotating. The rotating shaft rust is stopped, and the seven-pin plug is reconnected with the supplier motor and the electrical box failure . 4.

Please remove the dirt and check the vacuum gauge and vacuum pump . 7. Replace the vacuum hose when aging the vacuum hose ; 8. Loosen and tighten the top and bottom screws of the main mandrel ; 10. The motor temperature is too high (room temperature plus 40 °C is normal) overload stop, the shaft is turned by hand, whether it is very heavy, remove the dirt on the contact part of the sealing ring and the glass shaft, apply vacuum grease ; 11. The speed display does not match the actual voltage instability, and it has its own error ; 12. The electric heating tube of the outer casing has cracks and water, please check with a professional electrician. frozen PUD red shrimp Pud Red Shrimp,Frozen Pud Red Shrimp,Fresh Pud Red Shrimp,Fresh Frozen Pud Red Shrimp Zhoushan Junwei Aquatic Products Co., Ltd. , https://www.junweiaquatic-intl.com
