DFLPH vertical chemical shielding pump

First, the product overview

DFLPH vertical chemical shielding pump is a vertical pipeline chemical shielding pump. It is mainly composed of pump body, impeller, shielded motor, etc. It adopts a new static sealing structure to prevent dripping water and ensure the working environment is free from pollution. It is mainly used for petroleum, Chemical, textile printing and dyeing, pharmaceutical, food, metallurgy, power station and atomic energy transporting corrosive media and media with special requirements. The product implements GB/T5656-1994 "Technical Conditions for Centrifugal Pumps (II)".

Second, product features

1. High efficiency and energy saving: Calculate the fluid dynamics by CFD, analyze and calculate the relationship between pressure distribution and velocity distribution in the pump, optimize the flow channel design of the pump, ensure that the pump has high-efficiency hydraulic line, and improve the efficiency of the pump;

2, static sealing structure: the motor is a shielded motor, no moving seal, do not leak dripping, to ensure that the working environment is not polluted;

3, low noise: using static noise design method to reduce noise pollution, the noise is 3 ~ 5% lower than the general pipeline pump;

4, installation, maintenance is convenient: pipeline design, the import and export caliber is the same and in a straight line, easy to install and maintain, daily maintenance is very simple;

5, the machine performance is good: the use of advanced double throttle ring balance method, axial force balance effect is good, effectively reduce the motor failure rate, improve operational reliability; high balance accuracy, rotor component dynamic balance accuracy of G1.0;

6. New casting process: Over-flow components of DFLPH pump (such as pump body, impeller, pump cover, sealing ring, etc.), precision casting with silicon melt, stable runner size, pickling process after pickling process The attachment, retaining the nature of the metal, does not affect the medium being transported by casting attachments.

7. Explosion-proof structure: The motor is an explosion-proof motor, which is suitable for all kinds of flammable and explosive media conveying occasions.
