Advantages of positive displacement rotary pump Qin Ping

Advantages, characteristics and applications of positive displacement rotary pump Qin Ping:

Precise delivery: The positive displacement cam rotor pump has high delivery accuracy and stability, suitable for occasions with high requirements for fluid flow rate and pressure

Widely applicable: This pump is suitable for transporting various liquids, viscous liquids, high viscosity liquids, as well as special media that are volatile, flammable, explosive, etc.

Low pulsation: The positive displacement cam rotor pump delivers fluid with minimal pulsation, which is beneficial for protecting the fluid structure and improving delivery stability.

Easy to maintain: The structure is relatively simple, maintenance and upkeep are relatively easy, and the maintenance cycle is usually longer.

Advantages of positive displacement rotary pump Qin PingProduct function

Efficient transmission: Achieve 'hard output' through mechanical extrusion, overcome centrifugal pump air binding and cavitation defects, and ensure continuous and stable liquid supply.

Process optimization: Accurately control the conveying flow rate to meet the demanding requirements of chemical production for proportioning accuracy.

Equipment protection: The dry operation protection function can automatically shut down when the material is cut off, preventing damage to the pump body.

Simplified maintenance: Online repair design supports replacing rotors without dismantling pipelines, reducing downtime losses.

Security upgrade: The dual end mechanical seal structure effectively prevents leakage and enhances the safety of use in the petrochemical industry.

Key points for use

Preparation before startup:

Ensure that the pump chamber is filled with medium and avoid dry operation (mechanical seals require medium lubrication).

The medium needs to be pre filtered (≥ 75 μ m) to prevent hard particles from damaging the rotor.

Open the inlet and outlet valves to avoid pressure build-up and motor stalling.

Operation monitoring:

Monitor pressure gauges, safety valves, and overcurrent protection devices to prevent overload operation.

Observe the temperature of the pump body (≤ 80 ℃) and check the cooling system at high temperatures.

Shutdown operation:

Cut off the power, empty the liquid in the pump, clean and rotate the rotor 180 ° to prevent deformation.

When transporting high viscosity media, it is necessary to dilute the media before stopping to prevent solidification.
