How to choose the correct slurry pump:
First, according to the working conditions, first determine which slurry pump to choose:
1 The working conditions mentioned here are understood as application industries, such as: beneficiation, coal preparation, sand extraction, etc. (This step is very important and also a prerequisite for selection)
2 Flow and lift are the two most basic parameters for pump selection:
a: Initially determine the general situation of the pump through the working conditions, such as which series model or whether the material is considered, etc.
b: After determining the series model of the pump, read the performance curve through the flow rate and head to determine the specific model and size of the pump.
c: Read the curve and calculate the power: The parameters that must be known for the calculation of the pump's shaft power include flow, head, efficiency, and the proportion of slurry; the efficiency (η) is determined by the flow and the lift, which can be read out by reading the performance curve; customers of the proportion of slurry Can not provide only through experience. Generally (between 1-2), the technical calculation will give an estimated value to calculate the power.
d: Calculate shaft power P = m * g * h / η Its derived formula: P = ρ * Q * H / 102η (In the actual calculation, pay attention to the use of safety factor)
e: Motor power. The final motor power is taken as the motor power closest to the shaft power through the shaft power.
Second, more parameters: working conditions flow head. Specific gravity of slurry. Specific gravity of solids. concentration. Ph temperature. According to a basic process, except that in step C, the slurry specific gravity parameter directly uses the value provided by the customer, or calculates the slurry specific gravity through the solid specific gravity and concentration.
The weight concentration generally mainly considers the degree of abrasiveness of the slurry. For a certain slurry, the higher the concentration, the higher the abrasiveness will be, and the specific gravity of the slurry will be higher. Therefore, we have a heavy, neutral, and light slurry pump, which is based on the concept of slurry content, and there is no strict limit.
Ph value is one of the material factors that we judge is the material of the pump's overcurrent parts. (Generally, the pH value of 5-12 is the range of metal overflow parts. The rest of the range is rubber or other special materials. Here is the theoretical number range. Set, to be applied flexibly);
Temperature is also one of the factors that determine whether the material can be used. Generally, the temperature is rarely considered in most cases, but sometimes there are special operating conditions that require temperature.
Third, detailed parameters: working conditions, flow head, slurry, specific gravity, solids, specific gravity, concentration, Ph, temperature, D50, D80, pipeline (pipe, elbow, valve, gradually (shrink, expand)), viscosity, etc.
It is still in accordance with the basic process of one, but in this type of detailed parameters, it is generally the bidding project, or the client is very professional, so that it can provide so many detailed parameters. In general, the parameters that can be provided to two are already detailed. Some large projects and large bids will have a specific design unit or department to provide customers with detailed data, so it is possible to provide three such levels of detail. In fact, this detailed parameter mainly increases the parameters of the pipeline, and the pipeline is a parameter for calculation (dynamic head). Generally, many customers cannot provide detailed pipeline conditions, or the pipeline is simple, so they are ignored and directly provided. We only need to calculate the head, but once the detailed pipeline is provided, we need to calculate the dynamic head by ourselves. The calculation of the dynamic head is relatively complicated, but there are ready-made formulas to apply.
