1. Replacement, the selection of parameters and the actual operating conditions close to the centrifugal pump to ensure that the replacement of the pump is always running in an efficient state. We made a centrifugal pump before and after the replacement efficiency comparison experiments show that the replacement of inefficient, high consumption centrifugal pump, pump efficiency can be increased by about 10%.
1.WORKING PRINCIPLE
Double-tapped rotary vacuum dryer is a double conical rotary tank, the tank in the vacuum state, into the jacket through steam or hot water for heating, heat through the tank wall and wet material contact. Wet material after heat evaporation of water vapor, through the vacuum pump through the vacuum exhaust pipe is pumped, because the tank is in a vacuum state, and the tank rotation of the material constantly up and down, inside and outside, so accelerate the drying speed of the material, improve drying efficiency, to achieve the purpose of uniform drying
2.FEATURES
It is a drying equipment integrating mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device (if there is no need to recover solvent, the condenser can not be used). The internal structure of the machine is simple, easy to clean, easy to operate, can reduce labor intensity and improve the working environment. At the same time, because the container itself rotates when the material also rotates, but there is no material on the wall, so the heat transfer coefficient is higher, the drying rate is large, not only save energy, and the material drying uniform and full.
3.MAIN APPLICATION
It is suitable for vacuum drying and mixing of powder and granular materials in pharmaceutical, food and chemical industries, especially for materials with the following requirements
Heat-sensitive materials that cannot accept high temperatures
Oxidized and dangerous materials
Materials requiring recovery of solvents and toxic gases
Materials with very low residual volatile content are required
Material with requirements for crystalline shape
In addition we also have other machines for u chosoe,such as spices Powder Pulverizer ,powder mixer,Capsule Filling Machine,capsule Polishing Machine,Capsule Counting Machine,tablet press,vacuum dryer etc

2. Frequency energy-saving technologies. On the design parameters greater than the actual operating conditions of centrifugal pumps, installation of frequency control device, always running in the high-efficiency zone.
3. Promote new energy-saving products such as high-efficiency and energy-saving permanent magnet speed regulating motor and dual-power motor on the main centrifugal pump.
4. Centrifugal pump choice. Selection of new pump, the pump should be selected large manufacturers to ensure high efficiency centrifugal pumps.
Centrifugal pump maintenance.
(1) to check and adjust the shaft seal of the centrifugal pump frequently to reduce the volume loss;
(2) After the centrifugal pump has been operated for a total of 10,000 h, overhaul should be carried out to restore pump efficiency.
(3) Promote the application of the bellows sealing technology on the centrifugal pump to completely eliminate the leakage of the centrifugal pump and improve the volumetric efficiency.
6. Regularly clean the filter cylinder, check the pipeline connection, to ensure that the centrifugal pump into the fluid pipeline.
7. In strict accordance with the centrifugal pump operating procedures, pump the pump to open the previous one, open the inlet valve, close the outlet valve, exhaust venting, check the pump inlet pressure meets the requirements. Prevent cavitation of the pump from occurring due to low fluid pressure and insufficient flow rate.
8. When a centrifugal pump is used to pump a slurry flow of liquid containing large, medium and small sizes of material, the liquid is tangentially injected into the cylindrical chamber to form a swirling flow and a portion of the liquid is tangentially directed from the Chamber; injecting the slurry axially into the chamber, the vortex separating the oversized material from the rest of the slurry and liquid; axially removing the remaining slurry and liquid from the chamber and injecting it into the inlet of the centrifugal pump ; Using the material from the centrifugal pump as the ejection liquid forming the vortex to reduce wear on the centrifugal pump impeller and increase the efficiency of the centrifugal pump.
9. A method of reducing the wear of a centrifugal pump impeller and increasing the efficiency of a centrifugal pump when the centrifugal pump is used for pumping a mud stream containing liquid of a large size to a small size in a liquid, characterized in that it comprises: a. Forming a vortex into the vortex chamber and tangentially removing a portion of the liquid from the chamber; b injecting the slurry axially into the chamber, the vortex separating the large size of the material from the remaining slurry and liquid; c The remaining slurry and liquid are axially removed from the chamber and injected into the inlet of a centrifugal pump; d the material pumped out of the centrifugal pump is used as the ejection liquid forming the vortex flow; therefore, the large-sized The material is discharged toward the outer circumference of the vortex flow so that medium and small size materials and liquids are sprayed into the centrifugal pump thereby reducing the wear of the impeller and allowing the pump to operate at a high speed and hence the efficiency is improved.
10. Pumps on a regular basis for the pump test, pump low pump group, to find out the reasons in time to take appropriate measures to be resolved.
