As a manufacturer of sand dredging pumps and mud pumps, we provide dredging equipment solutions.
The selection of general mortar dredging pump is closely related. This is mainly to let customers know what they need to do before choosing a dredge pump, so as to facilitate the selection calculation and determine which type of mud to use. The pump is more suitable.
1. First of all, determine whether to use our pump by working conditions. The working conditions mentioned here are understood as mineral processing, coal processing, sand pumping and other application industries. (This step is very important, but also to do the selection of the premise)
2, flow and head are two basic parameters of the selection of pumps.
a: the initial determination of the pump through the working conditions of the general situation, such as the model of the series or whether to consider materials, etc.
b: after determining the series model of the pump, the flow and lift read the performance curve to determine the specific model and size of the said pump.
c: read the curve and calculate the power: the parameters that must be known to calculate the pump shaft power include flow rate, head, efficiency, slurry specific gravity; efficiency (η), determined by flow rate and head, is read by reading the performance curve; the customer cannot just provide it through empirical points. Usually (between 1-2), the power is calculated for estimation during the technical calculation.
d: calculation of shaft power P=m*g*h/η. derived formula: P=ρ*Q*H/102η (note the safety factor in the actual calculation)
e: motor power, the motor power closest to the shaft power and greater than the shaft power is the final motor power.
Condition flow head pulp specific gravity solids specific gravity concentration Ph value temperature according to the basic process of I, but step C pulp specific gravity parameters directly from the customer to provide the value of the calculation, or solids specific gravity and concentration used to calculate the slag. Pulp specific gravity. Stone pump industry
The weight concentration generally considers the degree of abrasion of the pulp. For a certain pulp, the higher the concentration, the higher the abrasiveness and the higher the specific gravity of the pulp. Therefore, we have a heavy duty, neutral, light duty slurry pump, which is a concept based on slurry content. There is no strict limit. ph value is one of the material factors we judge as pump overflow parts (generally ph value 5-12 is considered metal overflow parts range, the rest of the range is considered rubber or other special materials. Here, the theoretical range of values can not be killed. Setting, be flexible)
Temperature is also one of the factors that determine whether a material can be used. Generally temperature is mostly a factor that is rarely considered, but sometimes there are special cases that require temperature.
We provide dredging equipment solutions, including submersible dredge pumps, booster pumps, sand discharge pumps, suction boats, small pumps and pump parts, mud pumps, please contact us.
