Fluorine pump is a kind of fluid conveying equipment widely used in chemical, pharmaceutical, environmental protection and other fields, and its selection is very important to ensure the smooth progress of the process. The following are the main factors to be considered when selecting the lining pump:

1. fluid properties

Liquid properties include the name, physical properties, chemical properties and other properties of the liquid medium. The physical properties include temperature C, density D, viscosity U, solid particle diameter and gas content in the medium, etc. This involves the head of the system, the calculation of effective cavitation allowance and the type of suitable pump: chemical properties, mainly referring to the chemical corrosiveness and toxicity of the liquid medium, it is an important basis for selecting pump materials and selecting shaft seal types.

1. Medium: Consider what the fluid being transported is, including its chemical properties, corrosiveness, toxicity, etc. The fluoroplastic lining is resistant to corrosion, so it is suitable for a variety of media.

2. Concentration: The concentration of solutes in certain fluids will affect the performance of the pump, and high concentrations may cause crystallization or precipitation, affecting the normal operation of the pump.

3. Temperature: The temperature of the fluid affects the material selection and performance parameters of the pump. High temperatures need to take into account the thermal stability of the material.

2. process conditions

1. Flow rate: Select the appropriate pump model according to the flow rate required by the process. The flow rate is one of the important performance data of the pump, which is directly related to the production capacity and transmission capacity of the whole device. For example, the design institute can calculate the normal, minimum and maximum flow rates of the pump in the process design. Select the pump, based on the maximum flow, taking into account the normal flow, in the absence of maximum flow, usually desirable 1.1 times the normal flow as the maximum flow.

2. Head: The head required by the device system is another important performance data for selecting pumps. Generally, the head should be selected after enlarging the margin by 5% ~ 10%.

3. Pressure: Determine the maximum pressure drop required and the maximum pressure capacity of the pump to ensure that the pump runs at a stable working point.

4. Running time: continuous operation or intermittent operation, the selection and performance requirements of the pump are different.

3. performance parameters

1. Head: According to the actual situation of the process, determine the required head.

2. Power: Select the appropriate motor power to ensure the efficient operation of the pump.

3. Efficiency: Consider the efficiency of the pump and choose a high-efficiency and energy-saving pump model.

4. material selection

The flow parts of the lining fluorine pump are usually made of fluorine plastic material, which has good corrosion resistance. However, other parts such as housings and bearings may need to be made of other materials according to actual working conditions.

5. manufacturer reputation and after-sales service

Choose a reputable manufacturer that can guarantee the quality and performance of the pump. In addition, perfect after-sales service is also an important factor to consider when selecting models, so that problems can be resolved in time.

6. cost considerations

Selection also need to consider cost factors, including equipment acquisition costs, operating costs and maintenance costs. Under the premise of meeting the process requirements, select the most cost-effective pump model.

To sum up, the selection of lining fluorine pump involves many factors, which need to be considered comprehensively according to the actual situation. The correct selection can ensure the stable operation of the pump, improve production efficiency and reduce maintenance costs.
