ALLWEILER screw pump It is a centrifugal pump widely used in the industrial field, mainly used to transport high viscosity liquid and suspended particles. It is characterized by large flow and small pressure change, and is suitable for conveying media with high concentration, high temperature, high viscosity and easy crystallization. The following is true of ALL WEILER Screw pump Discussion on medium requirements and pump matching and commissioning.

First, ALLWEILER screw pump can transport various media, such as chemical media, petroleum products, food, pharmaceuticals, plastics, pulp and sludge. Before selecting the pump medium, we need to understand the characteristics and requirements of the medium.

Physical properties: including viscosity, density, temperature and particle content of the medium. ALLWEILER screw pump is applicable to media with viscosity higher than 30 cst (for some special models of pumps, the viscosity can be lower than 30 cst), and the temperature range is usually - 10 ℃ to 120 ℃. For medium containing particles, COLFAX agent The pump shall be designed to handle particle size and concentration.

Chemical properties: involving the acidity, alkalinity, corrosiveness and flammability of the medium. For corrosive media, select the pump head and seal of anti-corrosion materials. For combustible media, explosion-proof pumps shall be selected according to explosion-proof requirements.

Transportation distance and height: ALLWEILER screw pump has high transportation capacity, CIRCOR SECCO However, the conveying distance and height are also factors to be considered. By selecting appropriate pump type and determining reasonable pump head and driving power, the medium can be smoothly transported to the required position.

Once the medium requirements are determined, the next step is to match and debug the pump.

Pump matching: select the appropriate model ALLWEILER screw pump according to the characteristics and requirements of the medium. The technical parameters of the pump shall meet the requirements of medium viscosity, temperature, flow and pressure. In addition, the size and concentration of particles in the medium should also be considered. According to the process requirements, it is also necessary to determine the material, sealing mode and driving mode of the pump.

Pump commissioning: before commissioning the pump, it is necessary to ensure that the pump is installed correctly and connected well. Before commissioning, check the sealing performance of the pump to avoid leakage. Then, inject the medium into the pump body, start the pump, gradually increase the speed of the pump, and observe the operation of the pump. During commissioning, it is necessary to pay attention to the flow, pressure, temperature, noise and other parameters of the pump to ensure that the pump can operate normally and meet the process requirements.

Commissioning precautions: When commissioning the pump, the following points should be noted:

Before starting, make sure that the rotation direction of the pump is correct. Viking

The temperature rise of the pump shall be controlled within a reasonable range to avoid overheating of the medium.

During commissioning, observe the vibration of the pump to ensure smooth operation.

For high viscosity media, the pump speed and flow should be adjusted according to the actual situation.

After commissioning, record all parameters of the pump, and make necessary adjustments and maintenance.

The above is a discussion on the medium requirements of ALLWEILER screw pump and the matching and commissioning of the pump. By understanding the characteristics and requirements of the medium, and selecting the appropriate pump type for matching and debugging, it can ensure that the pump can operate normally and meet the process requirements.
