Basic alarm function:
When a gas leak occurs, the gas alarm generates an audible and visual alarm while opening the exhaust fan and closing the solenoid valve. The alarm or fault information of the equipment will be sent to the management personnel's mobile phone and the computer monitoring center through the short message way, forms the perfect warning system. At the same time, it can also be sent to a higher-level monitoring center to form a higher-level monitoring information system.
Simultaneous detection of multiple gases and strong compatibility:
The system can detect toxic gases and combustible gases at the same time. When combustible gases are sampled, the machine displays LEL and PPM when toxic gases. Combustible gas alarms are factory set to 25% LEL and 50% LEL, and toxic gases are set to 25% and 50% of full scale. Alarm concentrations can be adjusted appropriately for a detector.
Alarm recording function:
The system can record alarm records indefinitely (recorded on the detector's alarm time, alarm concentration and detector number).
System failure detection function:
This system has the function of automatically detecting system faults. It can detect the main power supply undervoltage, backup connection fault, charger connection fault, detector connection, sensor internal short circuit or open circuit fault of this system.
Two-level alarm function:
The system can achieve two levels of alarms at preset leakage concentration points: low limit alarms and high limit alarms. The two alarm concentrations can be adjusted as required by the user.
Easy to install and debug:
Compared with conventional point-to-point gas alarms, our gas detectors are designed with industrial integration, manufactured strictly according to the specifications of industrial-grade products, and tested at the factory, so that the use of the entire gas leakage alarm system greatly simplifies the investment of personnel equipment. It not only reduces project cost but also facilitates system installation, commissioning and maintenance.
Open deep groove ball bearings are manufactured without seals to allow for the free circulation of either oil or grease, used in gearboxes and other environments where no foreign matter would be present and a lubricant supply is available. Open type single row deep groove ball bearings are used in a wide variety of applications.
Open deep groove ball bearings are simple in design, non-separable, suitable for high speeds and are robust in operation, and need little maintenance. Open type bearings are cost effective selection.
Feature of our deep groove ball bearing:
Classified according to the Retainer/Cage:
Nylon cage open deep groove ball bearing: Our KA(Nylon retainer) series bearings Obtained MA certification of China Coal Research Institute, safety certificate of approval for mining products (rollers) in China, with good performance of anti-seize and anti-static.
Steel cage Open Deep Groove Ball Bearing: Thicker cage with stronger rivet, which consist more reliable structure.
To be the first class, to do the best quality, to make users satisfied, to ensure customers relieved, are our enterprise purposes. Welcome bearing dealers` and Conveyor Idler manufacturers contact from all over the world, and become our partner.
