The choice of slurry pump motor is very important, mainly to determine the motor model, specification, model pump and motor selection should follow the following principles:
1. Meet performance requirements
Pump performance mainly refers to pump flow, head and cavitation allowance, followed by pump speed, power and efficiency people tend to pay attention to pump flow and head, and often ignore the cavitation allowance of the pump in fact, when the pump cavitation does not meet the light will reduce the performance of the pump, shorten the service life, heavy can not be used.
2. Meet the process and installation requirements
Process requirements are the performance requirements of the supplementary pump transport medium temperature, properties, viscosity, corrosion, impurities should also meet the requirements but also consider the installation requirements.
3. Economic investment
Should consider one-time investment and long-term use cost economy, one-time investment refers to the purchase of pump, motor, pipeline costs and pump station construction investment long-term use economy is to consider the power consumption, pipeline hydraulic loss pump and motor life and maintenance costs.
4 pump installation, use, maintenance, repair convenient
The above is the principle of selection of slurry pump and motor pump selection is correct, directly affects whether the pump meets the requirements of use, whether economic, convenient if the improper selection, will cause uneconomic operation, easy maintenance, short life, high purchase cost, and even can not be used.
