Submersible pump explosion - proof grade requirements

Submersible pump we have it with explosion-proof motor has become an explosion-proof submersible pump, motor explosion can be divided into D2BT4 (solid explosion) and D2CT4 (gas explosion). No matter what kind of explosion-proof way is to prevent the use of pumps when the spark occurred accident, the following Shanghai Weihu submersible pump manufacturers to introduce explosion-proof submersible pump explosion-proof grade requirements.
Explosion-proof submersible pump explosion-proof requirements: This requires the use of electrical equipment should be designed and manufactured according to the provisions of the conditions, in the above-mentioned explosive use of the occasion, even if the equipment failure, it will not cause the surrounding explosive The gas environment is ignited and exploded.
To make the diving motor has a certain explosion-proof performance, can be adapted to the use of explosive atmospheres in the requirements, is to dive motor structure, parts manufacturing materials and manufacturing processes and other specialized measures to be guaranteed. Explosion-proof submersible pump is based on the general submersible sewage pump on the basis of optimization and improvement, submersible motor in the ordinary submersible sewage pump submersible motor based on the use of explosion-proof motor, pump outside the cable leads to the use of explosion-proof head, its role in the conductive part of the explosive and explosive Interception of the media, or to prevent dangerous sparks and local heat generation in the conductive parts that may be in contact with the explosive mixture.
