The specific performance requirements for the submersible jet mixer QJB5/12-620/3-480/S are as follows.

1. The oil temperature should generally not exceed 60 ℃.

2. For rolling bearings without oil rings, the oil level should not be lower than the center of the ball; For bearings with oil rings, the oil level should be able to submerge one-fifth of the diameter of the oil ring. In order to monitor the oil level, oil level gauges or oil gauges should be installed on the bearings.

3. The quality of the oil cannot be ignored, and it is necessary to ensure that the submersible mixer cannot be filled with water or impurities, and cannot emulsify or turn black.

4. During operation, always pay attention to the sound of the mixer, especially when the rolling bearings are damaged, abnormal sounds may occur.

The bearing isagitatorsThe core of the equipment, NSK brand, is that bearing failure is equivalent to a problem with our heart, which is quite serious. Therefore, we must protect the submersible mixerThe 'heart' is the key to ensuring the normal operation of the submersible mixer equipment.

Installation and acceptance reference data for submersible jet mixer completed

installagitatorsAfter the work is completed, the staff need to conduct acceptance testing on the equipment. The specific detection data can be based on the following data.

1. The allowable deviation for the plane position of the submersible mixer is 20mm, which can be measured and checked with a ruler.

2. The allowable deviation for the verticality of the guide rail is 1000mm, which can be checked with a plumb line and ruler.

3. The allowable deviation for the elevation of the submersible mixer is 20mm, which can be checked with a level and ruler.

4. The allowable deviation for the installation angle of the submersible mixer should be less than 10mm, which can be checked using the pay off method and protractor.

How can we ensure that the error of the installed submersible mixer equipment is within the allowable range as much as possible? Then we need to pay attention to the following three things when installing the submersible mixer.

1. When lifting a submersible mixer with a hook, the impeller end should be tilted 5-10 degrees above the horizontal plane.

2. The guide rod or guide wire should be perpendicular to the horizontal, and vertical correction can be used.

3. By adjusting the chain on the lifting device, the lifting hook and the lifting center of gravity of the submersible mixer are on the same vertical line during the sliding process of the submersible mixer along the guide rod or guide wire.
