Installation
- Removing:
The lugs is only lifting place(unpackaged). Do not roll or use crossbar. Avoid vibrating or bumping. Pulling coupler and clamps is forbidden.
- Lifting:
Wrire rope must be hitched on setted place such as nozzles of jacket and supports. Handle with care .Don' t collide. The lift hooks on the head are only used to sling the head.
- Inspecting before assembling:
The inspector whose shoes should be rubber-softandclear, gets into the vessl to inspect if the glass-lined surface was damaged and if there were abnormal phenomena.
- Fixing flange:
Along the diagonal line, tighten screw bolts gradually. Put forth your strength evently so as to avoiddamaging the glass-lined layer.
- Fixing clamps:
Firstly check the integr ation and quantity of clamps. When fixing, Keep the distance between clamps equal, the degree of tightness fair in ordre to assure operating safely and sealing reliably.
- Installing agitator:
a. Fistly, put the agitator into the vessel(Put a soft mat on the bottom of the vessel before hand).Then lift the head and take its predeter mined place,and covered the shafl with the shaft sealing device, Lift up the agitator, connect it with the out put shaft of the motor, and lock them with check nut or check bolt.
b. Adjust the axiality and perpen dicularity of shaft and seal up to technical specification. Turn the agitator slowly. If there is no abnormal phenomena, and the agitator rotates freely, then try starting motor till everything is allright, (The time of running is not too long ).
- Selecting gasket:
Elect the gasket based on the medium category, concentration and temperature of the working medium. The perfor mance and using method of the gasket should meet the technological re-quirements. the gasket, such as asbestos filled rubber and rubbers covered with PTFE.
- Welding:
a. Do not weld at the external surface of inner Vessel. b. When welding nozzles, lugs and supports, employ electro welding and take cooling measures. Gad welding strictly prohibited. c. When welding, the nearby glass-lined surface and nozzles must be covered tightly to avoid damaging them by splashing welding slag.
Operation
note:
- Prevent only metal and hard object from dropping into the vessrl to damage glass-lined surface.
- Since temperature changed suddenly, the service life of vessel is influenced by internal stress. So the user must try their best to avoid feeding hot material into cool reactor or cold material into hot reator.
- When operating a jacketed equipment, generaly, fist 0.1Mpa(g) pass through it and maintain this pressure for 15 minutes, then raise pressure and temperature slowly till operating pressure.(It¡¯s suitable for raising pressure at 0.1Mpa ever ten minutes).Heating or cooling shall be within specified temperature, The operating temperature of the equipment is 0¡«200¡æ.Resistance to sudden cooling:110¡æ,resistance to sudden heating:120¡æ.If the temperature is beyond the limits, Please give cleart indication in order contract ,we can do it specially.
- Discharge:If outlet valve, outlet pipe are obstructed , use nonmetallic tool to poke ,Don¡¯t bump and strike rudely.
- filling acid liquid into jacket is not permitted ,so to avoid glassed steel reacting with hydrogen and cauing fish scaling damage of glass-lining.
- cleaning:Do not use metal tool to clean the internal .The sticking material must be cleaned timely and thoroughly.
Storage
Takes good care of the equipment and keep it in store house when equipment is stored outdoors, it should be covered, avoiding drenched. In order to avoid freezing and crazing the glass-lining, the gathering water in shell, jacket, pipe must be clear away before winter comes particulary in cold district. Preventing friction, striking and bumping in the storage period.
