Installation of glass lining equipment

1.Lifting of the equipment

When hoisting the glass lining equipment,lift the equipment at the specified position (such as supports and lifting ears). Do not use manholes, pipes, and clips as lifting ears. Do not directly contact the glass-lined surface with hard objects.It is strictly for-bidden to knock, collide or bump the glass-lined surface. Do not move the device by rolling or crowbar.

2.Inspection before assembly

Before the assembly of the glass lining equipment, the personnel, components and installation tools shall be reliably and effectively protected against the glass lining surface when entering the equipment.It is strictly prohibited for hard objects to fall and hurt or scratch the glass-lined surface.

3.Installation of equipment clamps and flanges (bolts)

Check whether the clip,flange (bolt) is complete,whether the number meets the requirements, the clip should be installed to ensure that the distance is equal,tighten according to the specified torque to ensure safe operation and reliable sealing.When the flange is installed,it should be gradually tightened in pairs along the diagonal direction with uniform force, and should not be completely tightened at one time to avoid uneven force resulting in the fracture of the glass lining layer affecting the service life.

4.Installation of the Mixer

①Check the mixing, machine seal and frame before installation.②First put the agitator into the tank (the bottom of the tank is laid with soft cushion),and then lift the tank lid to the predetermined position, while the sealing piece is fitted into the mixing shaft,and then the agitator is lifted and connected with the output shaft of the reducer, and the anti-loose device is locked.③First adjust the levelness of the tank,and then adjust the coaxiality and verticality of the mixing shaft and the seal,and make the mixing shaft rotate slowly after meeting the specified technical requirements.(clockwise rotation) When the operation is flexible and there is no abnormal phenomenon,water can be injected in the tank and the test run can be carred out with water substitute.

5.Welding

Welding on the outer wall surface of the glass lining equipment is strictly prohibited. Welding nozzle, tank ear, ear holder on the jacket,all use electric welding,and adopt cooling measures, absolutely do not use gas welding.When welding near the space of the glass lining layer, the glass lining surface, pipe mouth and kettle mouth should be tightly covered to avoid the splash of welding slag and damage to the glass lining surface.

6.Installation Acceptance

After the equipment is installed,the glass-lined surface should be inspected again, and rope ladders made of wood and other materials should be used to enter the tank,and the protection work near the manhole flange and the lower part of the tank including other places that come into contact with the glass-lined surface should be done. Use the flashlight visual inspection method to check all the glass lining layer. If the electrical spark detector is needed for detection,the voltage should not exceed 7000V to prevent damage to the glass lining layer.
