materials It has the advantages of anti-corrosion, anti rust and resistance to various solvents G Standardized connection, easy to disassemble H Equipped with a vacuum meter, Zui can choose the best working vacuum for low boiling point materials 1 It is very convenient to use polytetrafluoroethylene material and special rubber compound seal ring for sealing, which can resist various solvents and keep high vacuum 3 Specific steps of instrument installation: 1 A after unpacking, check whether the main accessories of the machine are complete according to the packing list 2 B assemble the stainless steel pipe and fixed parts as shown in the attached figure 3 C install the electrical box on the top of the right rear upright post, screw in the screws, and insert the seven core plug The vacuum gauge is installed at the rear end, and the screw is tightened 4 D according to the use height, fix the round bracket of the kettle on the vertical rod slider, place the kettle on the bracket, use the semicircle hoop to fix the neck of the kettle, insert the vertical rod slider, tighten the fixing screws after closing, and note that the main body of the reaction kettle is vertical during installation 5 The stir bar is fixed on the gear ring chuck of the main shaft of the motor The stir bar passes through the middle of the cover to rotate the bearing, and tightens the special connector, then adjusts the position of the motor, and concentrates on the concentricity of the vertical 6 The slide block on the vertical bar is a stainless steel multi-purpose clamp for fixing and adjusting different directions and heights 7 The 40 × standard port on the left side of the bottle cap is inserted with a snake type reflux condenser, the 40 × standard port on the right side is a feeding port connected with a constant pressure funnel, the 24 × standard port in the front of the middle is a thermowell socket, the 34 × standard port behind the cap is a multi-functional standby port, the bottom is equipped with a discharge valve, and the upper and lower parts of the kettle are respectively the inlet and outlet of the circulating liquid The lower port is connected with the circulating liquid inlet and the upper port is connected with the circulating liquid return port 8 When installing the glass instrument, it must be clean, and the joints shall be coated with vaseline to prevent the glass from locking, and then vacuum grease shall be coated to prevent air leakage 9 Press the fixed device of universal wheel to mix If the mixing is stable, the debugging is good 4 Operating procedures: 1 Check whether the power supply voltage is consistent with the specification provided on the machine nameplate 2 Plug in the power plug, turn on the power switch on the frequency converter, and use the speed control knob to select the appropriate speed 3 The flow of materials and the power of motor speed may produce resonance at a certain point Please change the motor speed to avoid resonance 4 After the mixing rod is installed, it must be rotated by hand, and pay attention to whether the concentricity is good If the concentricity is not good, loosen the re clamp, turn on the power after the clamp is right, and adjust gradually from slow to fast 5 By using the mixing rod regulator, the mixing leaves can be 5cm up and down as required 6 If the sealing performance of the kettle is found to be poor, please check the rotating bearing in the agitator sleeve 7 All glass instruments of the reaction device are made of gg.17 low expansion coefficient and high temperature resistant borosilicate glass The user has prepared reaction bottle and other glass instruments Please confirm the quasi glass material to ensure safe use 8 The interlayer on the glass kettle is externally connected with the circulation port The hot oil can be used for heating reaction, and the cooling liquid can be used for low temperature reaction If the steam is used for heating, it can not exceed 0.5k-1k (try not to use pressure steam for heating) 9、 When the test is carried out at low temperature, the discharge valve at the bottom will frost When the valve is used, it must be partially defrosted to prevent the glass from being broken 10 If there are particles in the solution in use, it is possible to deposit residues on the polytetrafluoroethylene piston of the valve when discharging When reusing, the air tightness will be affected It is necessary to clean and reuse after discharging each time 5 Maintenance: 1 Check the instrument carefully before use Check whether the glass bottle is damaged and whether the interfaces are consistent Take care of it 2 Note: This equipment belongs to fragile products Please handle it with care when using The damage of fragile products is not within the warranty scope of our company If the customer needs, we need to charge the corresponding cost 3 The polytetrafluoroethylene switches at all places shall not be over tightened, which is easy to damage the glass 4 First, turn on the power switch, and then let the machine run from slow to fast When the machine is stopped, make the machine stop, and then turn off the switch 5 Each interface shall not be tightened too tightly It shall be loosened regularly to avoid long-term locking leading to connector seizure 6 After each use, it is necessary to use a soft cloth to clean all kinds of oil stains, stains and solvent left on the surface of the machine and keep it clean 7 Clean the sealing ring regularly by removing the sealing ring, checking whether there is dirt on the shaft, wiping it with a soft cloth, then applying a little vacuum grease, and then refitting it to keep the shaft and the sealing ring smooth 8 After the machine is stopped, loosen the PTFE switches, and the PTFE piston will be deformed if it is still in working state for a long time 9 The electrical part shall not be allowed to enter into water, and shall not be damped 10 Original accessories must be purchased Using other accessories at will will cause fatal damage to the machine 11 When doing any repair or inspection to the machine, be sure to cut off the power supply and water source first 12 The instrument shall be returned to the manufacturer for maintenance once after three years of use (recommended) 13 Wipe each interface with soft cloth (instead of napkin), and then apply a little vacuum grease (the vacuum grease must be covered after use to prevent the lime sand from entering.) 6 Solutions to common problems: the indicator light is not on as the original power switch is turned on If the external power supply is not connected or in poor contact, please check the power supply and socket by a professional electrician If the fuse is short circuited, turn the power switch to the off position, and then replace the fuse The power indicator is on, but does not rotate Stop using the rotating shaft due to rust, reconnect the seven core plug with the supplier's motor and electrical box due to failure The vacuum disappears suddenly The glass is cracked The switch is damaged Check the glass parts The switch is vacuumized, but the sealing ring is worn The vacuum switch is leaking Please replace the sealing ring Sometimes there is no dirt on the steel shaft when the switch is under vacuum Please remove the dirt Check the vacuum gauge and vacuum pump If the vacuum hose is aged, please replace it The main spindle of the vacuum hose is loose The tightening screw is loose The temperature of the tightening motor is too high (room temperature plus 40 ℃ is normal) shut down the machine under overload, rotate the shaft by hand, check whether it is heavy, remove the dirt on the contact part between the sealing ring and the glass shaft, and apply the vacuum grease The speed display is inconsistent with the actual situation The voltage is not stable, there is error in itself and there is crack in the heating pipe of the supplier's shell Please check the instrument and equipment by a professional electrician 50L, 30L, 20L double-layer glass reaction kettle: the equipment standard of the bottle mouth standard mouth is: 40 × standard mouth for
