Concrete mixing plant blackout treatment

Concrete mixing plant equipment such a large machinery, once the shortcomings will affect the emergence of a series of questions. In the concrete mixing plant operation process, there will be a lot of unexpected events, such as power, water, leakage, parts damage.

After the occurrence of power failure, the first power switch according to the operating procedures and procedures to hit the situation. Should promptly notify the operating staff, concluded that the power outage is caused by external power grid power failure, power plant equipment is still mixing shortcomings, and quickly determine the power off time. Assuming that the external power grid caused by power, then immediately notify the generator crew to start generating units, assuming that the mixing station power distribution equipment defects, resulting in power, should immediately repair the distribution equipment. Assuming the suspension in 30 minutes to 3 hours or more, you need to immediately notify the site, pump, notify the operating staff, the incident after processing for concrete.

The following are the same as the "

After the power, the mixing station operators should promptly handle the equipment within the production materials. After the concrete mixing plant shut down power failure, the air control system air compressor always in the exhaust situation, until the air compressor will start again when the intermittent exhaust, the appearance of this reason is because the air compressor pressure rise slowly, And there is oil appearance, indicating that the air compressor piston ring is now wear, need to be replaced. If there is no oil appearance, you can put the palm of your hand on the air filter inlet, assuming that the hot air to take out, that the intake valve damage, need to be replaced. Assuming that the palm of your hand is placed on the air-filtered inlet, feel a suction, but the strength is weak, it can be judged that the air filter is composed of other dust, impurity clogging, need to clean the filter, or may also replace the new filter.

The following are the same as the "

In order to ensure the normal operation of the concrete mixing plant, to avoid the sudden power outage, in addition to the above we need to understand the urgent treatment of course, also need to observe the operation of the mixing station internal circuit, and timely maintenance, maintenance, confinement generator normal operation.
