The original interlocking system and the disadvantage bearing temperature interlock alarm parking. When the bearing temperature is greater than 75e alarm, the bearing temperature is greater than 85e interlocking parking. The disadvantage is that the thermal resistance of the temperature measuring component is damaged and the connection failure is poor, which may cause the bearing temperature false indication interlocking accident to stop. Therefore, it is completely possible to cancel the interlocking parking function and strengthen the sound and light alarm patrol measures to ensure the safety of the unit; in addition, the unit bearing temperature is raised from the alarm to the jumping is a relatively slow process, and the operator has sufficient time to manually stop the vehicle. . Bearing vibration alarm parking. When one of the vibration values ​​of two radial vibration probes installed on one cross section is greater than or equal to 62Lm, the alarm is given, and when it is greater than or equal to 86Lm, the interlock is stopped. The disadvantage is that it is prone to the vibration false alarm interlocking accidental parking accident due to loose wiring of the Bentley vibration probe. And from the principle of mechanical vibration, there is no vibration value of two vibration probes installed in the cross section of the same shaft, but another normal state; from the perspective of probability, this situation appears Very small. Therefore, it is completely possible to change this alternative method to two-two, and at the same time strengthen the vibration alarm patrol, greatly reducing the possibility of accidental parking. Only the mechanical design of the super-high speed jumping, there is no ultra-high speed instrument interlock design. There are hidden dangers of mechanical slowness and insensitivity, but if you want to increase the three-redundant override interlocking system for overspeed parking, the necessary space for installing the rotating probe is not met mechanically. The anti-surge interlocking parking system is not perfect. The original design is when the differential pressure switch at the outlet of the air compressor appears twice, the surge alarm, and the vent valve is opened at the same time. When the action is 4 times, the turbine air compressor interlocks and jumps. There is a lack of a limit on the minimum opening of the inlet guide vanes, thereby reducing the automatic closing of the inlet guide vanes due to operational and instrument detection component accidents, resulting in a surge parking accident. double suction pump/split casing pump Split Case Pump,Double Suction Pump,Split Casing Pump Changhong Machinery Manufacture Co., Ltd. , http://www.dzpumpfluid.com
