Shielding motorelectric pump

Abstract:

YB, YBP shielding flame-proof three-phase asynchronous motors are normally known as s hielding

motor for pump or shielding motor for short. Pumps impeller i s directly installed to motors axle, and it

forms a sealed chamber (shielding electric pump) when being put into pump. Still seal replaces rotary

seal, which solves the leakage for comm on pump on propeller axle. The shielding motor is featured by

absolute sealing, reliable operation, low vibration and nois e, easy maintenance, and remote operation,

and more important, it improves operators working condition to guarantee body safety and prevent

peoples property from los ing. It plays an im portant part in atomic energy, chemical, air-conditioning, and

heating industries, etc.

The shielding pump, which is composed of this shielding motor and pump, is used to transport liquid

without solid, especially virulent, corrosive, radioactive, flammable, or explosive liquid, or liquid atexpensive price, or liquid that will bring in great harm if leaking.

YP Shielding motor (shielding three-phase asynchronous motor) is suitable to work under the condition

without explosive gas mixture; YBP Shielding m otor (flame-proof shielding three-phase asynchronous

motor) is suitable to work under the condition with explosive gas m ixture, and forms flame-proof

structure ExdBT3, ExdBT4 in accordance with GB3836.1-2.

The motor can be installed both vertically and horizontally:

Motors Shell: IP 55

Rubber jacket cable for connection.

Standard material for parts of motor that contact medium:

1. Shield Sleeve: 1Gr18Ni9Ti;


18/21



2. Axle: 1Gr17Ni2;

3. Gasket: PTFE;

4. Bearing: Phenolic impregnated graphite or furan resin;

5. Bearing sleeve, back impeller: Overlaying cobalt-chromium-tungsten alloy or spraying Ni-base

wearing-proof alloy upon 1Gr18Ni9Ti basal body;

6 Other material: 1Gr18Ni9Ti (1Gr17Ni2 for mos t fasteners).

The motors basic s tructure is that a layer of non-magnetic stainless s teel sleeve (called shielding

sleeve) is soldered to the plates of s tator cavity and rotator exterior surface to shield s tator and rotator

respectively from mediums imm ersion and corrosion. Motors rotator cavity is connected to pump cavity,

and filled with pumping liquid. The liquid recycles inside m otor to cool the motor (also lubricate bearing).

Cooled-water jacket is ins talled around motor seat to control water to cool motor.

Normal temperature shielding or flame-proof shielding three-phase asynchronous motor is leading a

sm all amount of pumping liquid to back bearing through filter, then to front bearing through the gap

between stator and rotator, and finally to pumps inlet for recycle.

High temperature shielding or flame-proof shielding three-phase asynchronous motor is also leading a

sm all amount of liquid from the joint of heat shielder and motor, through the cooling coiled pipe of water

jacket, the gap between s tator and rotator, and front bearing, then to the joint of heat shielder and m otor,

and back to cooling coiled pipe for recycling. A back impeller is installed on rotator to transport the

recycled liquid, and a heat shielder is installed between motor and pump to avoid motor from heating.
