Shield pump structure principle and ordinary centrifugal pump the same, the difference is the drive motor. The motor of the shield pump is completely enclosed in the second layer of isolation sleeve or shield sleeve.
In addition, the manufacture of the shielded pump is not complicated, its hydraulic end can be in accordance with the centrifugal pump commonly used structure type and related standard specifications to design, manufacture.
Shielding pump product features
* motor and pump integrated structure, all use static seal, so that the electric pump completely without leakage;
* completely closed and leak-free structure can transport toxic and harmful liquid substances;
* a shielded water-cooled motor and a cooling fan are used to make the pump run quietly with low noise, which is suitable for occasions with high requirements on environmental noise;
* adopt the graphite sliding bearing lubricated by conveying medium, so that the running noise is lower and manual lubrication is not needed, which reduces the maintenance cost; In recent years, the bearing material has added silicon carbide SIC, super hard, service life is better than graphite bearing.
* the vertical structure can be installed on the pipe road like a valve, which is convenient and fast to install, and can be maintained only by pulling out the motor and impeller, without removing the pipe.
* can cooperate with the shock absorber or cushion installation and operation, so that the electric pump in operation noise is lower.
