What are the types of motors used for corrosion-resistant pumps?

A corrosion resistant pump can run normally without the support of the motor, in fact, there are a lot of motor products on the market now, so how should we choose the motor we need? What we’re talking about today is the classification of corrosion-resistant pump motors. Y (IP44) series asynchronous motors The capacity of […]

Main spare part of centrifugal pump

Main spare part of centrifugal pump The main spare part are impeller, pump case and shaft seal device. 1, impeller The impeller’s function is to transfer the mechanical energy of the prime mover directly to the liquid to increase the hydrostatic energy and kinetic energy of the liquid (mainly to increase the static pressure energy). Impellers generally […]

What are the operating conditions of the pump?

When customer send inquiry to us, our sales colleagues always ask customer’s operating conditions. So what is “operating conditions”?, It’s “operating conditions” really important? Is it not enough to know the exact model? The answer is not enough, in order to enable each customer to better use the Sunpace’s pump, we often ask customer about […]

Operation and maintenance of Motor and accident treatment

Operation and maintenance of Motor and accident treatment Inspection of motor before starting The motor should be clean, no sundries, no leakage, no air leakage and no work. There is no abnormal phenomenon in the motor and its control box seat, the housing is well grounded, and the motor lead is negative. The mechanical part […]

Advantages of single screw pump

1.The single screw pump pressure gradient is improved, and the pressure of the seal chamber increases. Advantages: small pulsation, low noise, transport medium is not easy to aging. 2.Medium in the single screw pump along the axial direction of uniform linear motion. All, theoretically no pulsation of flow, no pulsation of pressure, small noise vibration. […]

Matters needing attention in centrifugal pump testing

1.Before starting the centrifugal pump, the idle load test should be prohibited, and the liquid test should be carried out according to the operation rules stipulated above. For the forced lubrication system, the temperature rise of the centrifugal pump bearing oil should not exceed 28 ℃. Bearing metal temperature should be less than 93 ℃. For […]
