Arranged in an engine room equipment device has nothing to do with the elevator Parts

Some real estate companies to ensure the buildings shape the overall appearance, the pressure pipe or fire hydrants, fire pipe set in the engine room without laying along the exterior wall. If the pipeline rupture, overflow out of the water will flow to the engine room control cabinet electrical components may be burned, part of the water will flow into the wells from the floor holes, caused by the car, the elevator system due to short-circuit caused the motherboard failure, brought serious economic losses. Therefore, the relevant units should be familiar with national regulations and standards, manufacture and installation of the elevator and elevator installation to fully understand the requirements of the related engineering.

2 civil engineering electrical engineering is too slow or the power supply cabinet assembly which do not meet

A considerable part of civil electrical construction can not keep up the installation period of the elevator, the elevator temporary power supply, delays elevator installation supervision and inspection time, prolonged construction period; some of the main power supply capacity is too small. For example: a unit of the elevator power 15kw rated speed of 1.5m / s, to enhance the height of 60m, rated current of 41A, the main power switch capacity is only 32A, so easily lead to the failure of the power supply system to the safe operation of the elevator can not.

3 elevator machine room ambient temperature and ventilation facilities do not meet the requirements

Most elevator machine room set at the top level of the building, a portion of the design in pursuit of the aesthetic appearance of the building exterior wall in the engine room with no or minimize open windows, resulting in engine room ventilation and lighting. GB7588-2003 "elevator manufacturing and installation of safety regulations elevator machine room should have proper ventilation, computer room environment temperature should be maintained between 5-40 degrees. In summer the sun a long time, the heat generated in the elevator is running, often makes the elevator machine room ambient temperature exceeded the national standard requirements, the failure rate of the operation of the elevator, and shorten the life of the product, although many construction units increased installed in the engine room exhaust devices still feel ineffective. Civil design requirements in addition to considering the aesthetic appearance of the building, but also pay attention to the elevator machine room ventilation, lighting, insulation, rain conditions. Installation of exhaust devices at the same time, set up the other side of the wall in the engine room air inlet (such as blinds), so that the air convection, which play a purpose to improve the room ambient temperature.
