The safety of chemical pumps is of top priority
Thread Content
In recent years, domestic chemical and pharmaceutical companies have sought to reduce safety distances and the amount of land required, and as a result they are converting underground tanks used for storing chemical substances into systems that transfer these substances to workshops or areas on the surface. The traditional method for transfer involves using equipment that creates negative pressure; however, this approach presents problems such as air resistance and cavitation, which reduce efficiency and cause environmental pollution. In cases where the substance has a low density, it may even be impossible to draw it up using this method. Clause 6.4.2 of the national standard GB25285.1-2010 \"Prevention and protection against explosions in explosive atmospheres – Part 1: Basic principles and methods\" specifies that \"for Class Ga: the surface temperature of all equipment, protective systems, and components that come into contact with explosive atmospheres shall not exceed 80% of the minimum ignition temperature of flammable gases or liquids, even in the event of rare failures.\" Obviously, using long-shaft submersible pump products in Zone 0 explosive environments violates the aforementioned national standards. The Refining and Chemicals Division of China National Petroleum Corporation experienced two explosion and fire incidents in 2010 and 2012 respectively due to the use of long-shaft submersible pumps; these incidents resulted in 5 deaths and some property losses. As a result, a formal order was issued in 2012 prohibiting the use of long-shaft submersible pumps in Zone 0 environments. What concerns the owners of chemical companies the most these days is safety. Tianjin Jiamaa Submersible Pump Co., Ltd. has been engaged in the design and manufacturing of explosion-proof submersible pumps for many years, possessing extensive expertise in explosion protection as well as rich production experience. The green-label chemical submersible pump is designed with an explosion-proof submersible motor; its explosion protection rating is EXDSIIBT4GA/GB, achieved through a combination of sealing and flame isolation. The cable leads as well as the explosion-proof connectors meet the GB3836-1 standard. Inside the motor, there are multiple protection mechanisms in place for overcurrent and overheating protection. Temperature control protection. Green-label submersible pumps that experience rare failures have a self-locking or self-destructing mechanism. These factors have enabled the Green Card submersible pump series to win customers’ trust since its introduction, thanks to its zero-failure rate, extended service life, and maintenance-free operation.
The safety of chemical pumps is very important. In recent years, domestic chemical and pharmaceutical companies have adopted the method of transferring the medium from tanks to workshops or the ground within the workshops in order to reduce the required safety distances and the amount of space needed. Traditional negative pressure suction methods suffer from problems such as air resistance and cavitation, which can lead to reduced work efficiency, environmental pollution, and the inability to achieve effective suction. At the same time, **standard GB25285.1-2010 also specifies the surface temperature for equipment used in explosive environments. To address these issues, Tianjin Jiamaa Submersible Pump Co., Ltd. has been engaged in the design and manufacture of explosion-proof submersible pumps for many years, possessing extensive expertise in explosion protection as well as rich production experience. The green-label chemical submersible pump is designed with an explosion-proof submersible motor, featuring an explosion protection rating of EXDSIIBT4GA/GB, which combines gasket sealing with flame isolation. Other aspects, such as cable leads and explosion-proof connectors, also meet the corresponding explosion-proof standards. In addition, this product features multi-level protection and temperature control protection, allowing it to lock itself or self-destruct in the event of rare faults, thereby ensuring the safety of equipment and personnel. Thanks to its rigorous approach to product design and manufacturing, the Green Label submersible pump series has won customers’ trust through features such as a zero-failure rate, extended service life, and maintenance-free operation. .
