Precision High-Power Digital Display Electric Stirrer

Precision Torque-Boosting Digital Display Electric Stirrer

I. Product Introduction

The precision torque-boosting digital display electric stirrer can be applied in fields such as biopharmaceuticals, biochemistry, food, nanomaterials, coatings, adhesives, daily chemicals, printing and dyeing, petrochemicals, and papermaking chemistry. This digital display electric stirrer is suitable for dispersion, stirring and other mixing processes of multi-viscosity systems in laboratories.

II. Add New Functions to Your Laboratory

1. Digital display

2. Powerful, vertical and elongated shape, humanized design

Based on the reliable RW20 series, performance and technical improvements have been made, with stable motor power

3. Two speed gears (high and low speed), ranging from 60 to 2000 rpm.

4. Penetration-type stirring paddle (only when fixed).

III. Optional Configurations

1. Four-blade propeller type: Standard stirring head, which makes the mixed medium flow axially from top to bottom with low shear force.
2. Three-blade propeller type: Makes the mixed medium flow axially from top to bottom, generating local shear force. Suitable for medium and high speed operation.
3. Dissolution type: Makes the mixed medium generate radial flow from both top and bottom; the strong turbulence and high shear force formed can crush particles in the liquid. Suitable for medium and high speed operation.
4. Centrifugal type: Double blades open as speed increases, suitable for use in narrow-mouth containers. Stirring effect is similar to that of four-blade propeller type. Suitable for medium and high speed operation.
5. Blade type: Generates tangential flow with low turbulence and good heat exchange performance, applied in occasions requiring gentle stirring of media. Suitable for low and medium speed operation.
6. Anchor type: Generates tangential flow, with high shear rate formed at the edge, preventing the mixed medium from depositing on the container wall. Suitable for low speed operation. It is ideal for stirring elements of medium and high viscosity fluids, applied in polymer reactions and dispersion of minerals in liquids.

7. Other special paddles: Various other types of paddles can be selected to meet your special working conditions

IV. Maintenance of Mechanical Stirrers

·1. Bearings bear all the load of the machine, so lubrication has a great impact on the bearing life, which directly affects the service life and operation rate of the machine. Therefore, the injected lubricating oil is required to be clean and the seal is good. The main oil injection points of this machine are: (1) rotating bearings, (2) rolling mill bearings, (3) all gears, (4) movable bearings and sliding surfaces.

·2. Newly installed wheel hoops are prone to loosening and need to be checked frequently.

·3. Pay attention to whether the operation of each part of the machine is normal.

·4. Pay attention to checking the wear degree of easily worn parts and replace worn parts in time.

·5. The bottom frame surface of the movable device should be cleaned of dust and other substances, so that when the machine encounters materials that cannot be crushed, the movable bearing cannot move on the bottom frame, resulting in serious accidents. 6. If the bearing oil temperature rises, stop the machine immediately to check the cause and eliminate it.

·7. If there is an impact sound when the rotating gears are running, stop the machine immediately to check and eliminate the fault before restarting.
