It is recommended to consider five aspects when purchasing a fluoroplastic alloy pump, including liquid delivery volume, lift, liquid properties, pipeline layout, and operating conditions. The details are as follows
Flow is one of the important performance data for pump selection. First, it is directly related to the production capacity and transportation capacity of the entire device. For example, the design process can calculate the normal, minimum, and maximum flow rates of the pump. When selecting a pump, take the maximum flow rate as the basis and take into account the normal flow rate. When there is no maximum flow rate, usually times the normal flow rate can be taken as the maximum flow rate.
Lift is another important performance data for selecting fluoroplastic alloy pumps. Generally, the head should be selected after enlarging the %% margin.
Liquid properties include the name of the liquid medium, physical properties, chemical properties and other properties. Physical properties include temperature, density, viscosity, diameter of solid particles in the medium and gas content, etc. This involves the head of the system, effective gas The calculation of corrosion allowance and the chemical properties of the appropriate pump type mainly refer to the chemical corrosiveness and toxicity of the liquid medium, which are important basis for selecting the pump material and the type of shaft seal.
Pipeline layout conditions refer to the liquid delivery height, liquid delivery distance, liquid delivery direction, the lowest liquid level on the suction side, the highest liquid level on the discharge side, and other data, as well as pipeline specifications and their length, materials, pipe fitting specifications, quantity, etc. , in order to calculate the system comb head and check the NPSH.
There are many contents of operating conditions, such as the operating saturated steam force of the liquid, suction side pressure, discharge side container pressure, altitude, ambient temperature, whether the operation is intermittent or continuous, and whether the position of the pump is fixed or movable. .
The correct selection of fluoroplastic alloy pumps can effectively maximize the performance of the equipment and improve work efficiency.
