QY type oil filled submersible pump

Product Introduction

QY type oil filled submersible electric pump（ http://www.pumpzc .. Com/qy/(abbreviated as submersible pump) is an electric drainage and irrigation equipment that combines a water pump and a three-phase asynchronous motor. It has reliable waterproof sealing performance, small size, light weight, does not require a pump room, does not require water injection, and is easy to use, maintain, and manage.

working conditions

• The submersible pump should submerge to a depth of no more than 5 meters underwater;
• The water temperature shall not exceed 40 ℃;
• The volume ratio of sand content or insoluble solid particles in water shall not exceed 0.1%, and the particle size shall not exceed 0.2mm;
• Non corrosive, with a pH value of 6.5-8 for water, such as regular room temperature water: well water, river water, lake water.

structural drawings

Structure Introduction: The QY submersible pump consists of three parts: a water pump, an electric motor, and a seal. Water pump section: located at the upper part of the submersible pump, coaxial with the electric motor, with three types of impeller forms: centrifugal mixed flow and axial flow. Motor part: The motor has a power of 2.2KW and 3KW, and is a squirrel cage three-phase asynchronous motor. It is vertically filled with No. 5 mechanical oil. The motor is located at the lower part of the submersible pump. Sealing part: including dynamic sealing and static sealing. The dynamic seal is an integral double end mechanical seal located at the motor shaft extension, which is installed in the cavity formed by the upper cover and water inlet joint, and filled with No. 5 mechanical oil. The static seal is located at the joint of the various parts of the electric pump and adopts an 'O' shaperubberseal ring.
