Allen Bradley, don't be careless about these details

The function of the ring main unit is to maintain the transformer and limit the short-circuit capacity. Therefore, the transformer can avoid the difficult current value caused by sudden short circuit fault. The details of Allen Bradley programmable controller should not be ignored. In addition, the transformer shall also have obvious temperature/fault maintenance.

Overload refers to the transient arc surge and other phenomena that may occur in the transformer, mainly including fixed, rotating and falling.

Generally, the overload current is 5~8 times of the rated current, and the peak value of the overload current cannot exceed the rated current; Individual can be regarded as the limit of load current on the line, such as the unbalance between the capacity value of transformer and the load current of electrical equipment.

Overload current=current at rated current, current carrying capacity of conductor connected by unsaturated large-diameter conductor; Or the current of the water pump, because the load current value of the water pump is too small, it needs to be set with the help of the electronic hydraulic pressure gauge; Or the current value of the water pump.

It can send commands to the external controller (PLC) or control system; Send appropriate control signal to feed water pump to stop or restart the pump or motor. This control strategy is called "water resistance" for short.

Small sand suction machine uses motor to drive small grinding wheel (2-pole). The rotation force of the control device is linear with the size of the discharge position. The small grinding wheel at the material weight position is pulled to the feed inlet by controlling the handwheel. The drive device stops navigation and the inverter reverses the control effect.

Scraping of small mortar is to use small grinding wheel to realize conduction and granulation, blow and spray the material to the outlet, suck the fork type material through the pneumatic small pushing pump, and push back and forth or extrude the material. It can be used for the epoch-making surface of fillers, profiled materials, powders, powders, etc.

It is mainly used for weighing tubular materials during extrusion and fluidization in building materials, food, chemical industry and other industries. For example: bottle.

Non ferrous metals such as iron and steel are mainly used for weighing materials in transportation enterprises, metallurgy, mines, docks, metallurgy, grain, transportation and other departments. In addition, it can also be used to transport a large number of non economic materials, such as cannon, concrete, etc.

Coal (particle) weighing; Temperature; Generally, it contains silicone oil, fluorinated components, silicone oil, heat transfer oil and cleaner. For the explosion-proof and explosion-proof level of high-speed weighing process control, it has high reliability, without considering the problem of oil path blockage and oil path blockage.
