The DJ rack is compatible with various host products, and the surrounding work environment is more complex. DJ stands for high temperature, low temperature, oil, acid, alkaline medium environment, unfavorable choose for general rubber flexible coupling of elastic element material, should choose metal flexible coupling components elastic. The elastic cylindrical pin gear coupling is not used in the situation where noise is strictly required due to the running of the column pin during operation.

Features of DJ frame:

(1) selection of speed reducer frame. In principle is according to the size of the diameter of axle reducer output to determine the frame model, as long as the interface forms and sizes, reducer output shaft size within a certain range can be decreased to the frame model. If the mounting size of the reducer is not in conformity with the frame, we can connect the speed adjusting plate and the reducer to meet the user's requirement.

(2) no fulcrum machine is strengthened. The machine strengthens the bearing point without shaft. The agitator shaft is the bearing support bearing of the two supporting bearings of the output shaft of the reducer, which can be used to transmit the small power, not to be subjected to or only to the small axial load, the mixing device not too strong. The coupling of mixing shaft and reducer must be used with a rigid coupling, especially with JQ type clamshell coupling or SF type three-point coupling.

(3) single support frame. With one of the following conditions, the single support frame is chosen as the best:

A, the mixing container sets the bottom bearing, as a bearing support.

B. The shaft seal is equipped with bearing (including rigid bushing) as a bearing point (the force degree is required according to the shaft seal)

C. Inside the mixing vessel, the center of the shaft is equipped with a guide bearing, as a bearing point (i.e., intermediate bearing).
