According to GB3836.3-2010 and IEC60079-7:2006, there are clear requirements regarding whether a purging device should be installed for increased safety motors. This includes assessing the safety factor of the motor, evaluating the potential spark hazard in the air gap of the rotor, and assessing the potential discharge hazard of the stator winding. If the hazard assessment factor is greater than 6, a purging device must be added to enhance the safety and reliability of the increased safety motor. Article 5.2.7 of the national standard GB3836.3-2010 states that 'increased safety motors must undergo ventilation purging before each start, and the responsibility for pre-start ventilation purging and maintenance of the motor lies with the user.' Therefore, using an intelligent automatic purging device to first replace harmful gases inside the motor casing before starting is not only a requirement for production safety but also a requirement of national standards.
The automatic purging devices produced by Nanyang Huaye include three types: increased safety purging system, positive pressure automatic purging system, and improved increased safety purging system. All are intelligent automatic purging devices that can be selected based on site conditions and project needs.
Our purging device advantages:
1. Fast response speed
The scientific design of the air circuit combines mode amplification and nozzle baffle technology, further enhancing the valve's low-pressure response performance. The use of a diaphragm large arc design greatly improves the sensor's sensitivity to micro-pressure responses, resulting in excellent dynamic response performance of the system, rapid leakage compensation response, and agile following performance.
2. Strong stability and high reliability
Relying on the technical strength of the national pneumatic laboratory, we boldly innovate air circuit design, striving for simplicity, rationality, and scientific design. Additionally, by using internationally renowned brands such as Bellofram and MAC from the USA, and BARTEC from Germany, we ensure strong product stability and high reliability. It can be said that all product performance indicators meet or partially exceed those of international products.

Bearing temperature measuring instrument
The temperature variation of bearings is an important reference data for the operating status of motors. In many situations, there is a need for signals to be transmitted remotely to the control room, while also allowing for direct visual observation of the temperature values on-site. Nanyang Huaye has designed and developed a temperature measuring instrument that features local display with remote signal transmission capabilities. According to project requirements, it can meet the needs for explosion-proof, mining, and general applications. It can transmit PT100, 4-20mA signals, and supports HART protocol for remote transmission. It can display readings with mechanical pointers or digitally, catering to various scenarios and requirements for temperature measurement.
Automatic Purging Device - Explosion-Proof Motor Ventilation Purging Modification
According to GB3836.3-2010 and IEC60079-7:2006, there are clear requirements regarding whether an increased safety motor needs to be equipped with a starting pre-purge device. This includes evaluating the safety factor of the motor, assessing the potential spark hazard in the air gap of the rotor, and evaluating the discharge hazard of the stator winding. If the hazard assessment factor is greater than 6, a starting pre-purge device must be added to enhance the safety and reliability of the increased safety motor. Article 5.2.7 of the national standard GB3836.3-2010 states that "increased safety motors must undergo ventilation purging before each start, and it is the user's responsibility to perform ventilation purging and maintenance on the motor before starting." Therefore, using an intelligent automatic purging device to first displace harmful gases inside the motor casing before starting not only meets production safety requirements but also complies with national standards.
Automatic Oil Supplementation Case for Motors
Equipment is an important element in enterprise production, and the good operation of equipment is a crucial guarantee for the smooth operation of the enterprise. To keep equipment in good technical condition, it is essential to pay attention to maintenance during its usage. The most important maintenance for rotating equipment is to carry out lubrication in a reasonable and comprehensive manner. Only in this way can friction be controlled, wear be reduced, energy consumption in transmission mechanisms be minimized, equipment lifespan be extended, and damage and failures be reduced, thereby lowering maintenance costs. Equipment lubrication is directly related to energy savings, material conservation, and labor efficiency, improving the lifespan, reliability, and safety of mechanical products, creating more material wealth, and mitigating risks.
