Ex d IIC T4 Explosion Proof Motor B35 Foot

The Ex d IIC T4 Explosion Proof Motor B35 Foot is a vertical, double-fixed explosion-proof motor designed specifically for high-risk industries such as petroleum, chemical, and pharmaceutical. Unlike the B3 (horizontal foot), B5 (vertical large flange), and B14 (small flange), the B35 adopts a unique structure of vertical installation + foot fixing + flange connection, balancing equipment stability and transmission efficiency.

Product Features

Dual-fixation design: Equipped with high-strength mounting feet at the bottom and a large-diameter flange at the top for direct connection to the load equipment, forming a "double-fixation" structure to ensure stable operation under heavy loads and high vibration conditions.

CT4 Hardcore Protection: Explosion-proof rating Ex d IIC T4 Gb, flameproof enclosure + surface temperature ≤85℃, eliminating the risk of explosion in environments with high-risk gases such as hydrogen and acetylene, meeting stringent safety standards.

Heavy-duty transmission expert: Specifically designed for large mixing equipment, high-pressure process pumps, and compressors, with a reinforced output shaft to withstand high torque impacts, lossless transmission, and extended equipment life.

Applications

This Ex d IIC T4 Explosion Proof Motor B35 Foot is specifically designed for high-risk, heavy-duty scenarios, covering the following fields:

Oil & Petrochemical: Direct-drive systems for large process pumps, mud pumps, and agitators.

Chemical & Pharmaceutical: Reactor agitators, high-pressure centrifugal pumps, and crystallizer drives.

Mining & Metallurgy: Mud transfer pumps and slurry mixers for gas environments.

Offshore Platforms: Explosion-proof compressors for drilling platforms and seawater treatment pump sets.

Installation Guide

Key Steps: Ensure Double Fixation to Avoid Safety Hazards

1. Base Fixation: Securely install the Ex d IIC T4 Explosion Proof Motor B35 Foot to the foundation plane using base bolts, ensuring it is level (allowable error ≤ 0.1mm/m).

2. Flange Alignment: Align the motor flange with the load equipment flange, and tighten the bolts evenly using a diagonal tightening method to avoid stress concentration.

3. Wiring Specifications: Use explosion-proof gland-sealed cables, ensuring a reliable grounding connection and avoiding loose connections or exposed wires.

4. Pre-Start Inspection: Confirm that the flange seal is tight, bolts are secure, and the explosion-proof surface is undamaged.

FAQ

Q1: What is the difference between B35 and B5?

A: Difference in installation structure:

B5: Vertical flange installation only, suitable for space-constrained scenarios.

B35: Vertical + foot + flange, double fixation, capable of withstanding higher loads and vibrations.

Q2: Is this Ex d IIC T4 Explosion Proof Motor B35 Foot suitable for offshore drilling platforms?

A: Fully suitable. B35 is CT4 explosion-proof certified, and its double fixation structure can withstand the high humidity, high salt spray, and vibration environments at sea. It comes standard with an anti-corrosion coating.

Q3: Can special flange sizes be customized?

A: Yes. Flange hole spacing and shaft diameter can be customized according to equipment requirements, and technical drawing confirmation services are provided.

Q4: How to maintain explosion-proof performance?

A: Regular (every 6 months) inspection:

1. Check for rust on the explosion-proof surface (can be protected with anti-rust oil).

2. Check for loose flange bolts.

3. Check for a healthy grounding wire.

4. It is recommended that maintenance be performed by a professional explosion-proof electrician.
