NasTwo ton guior one of the parallel branches is open circuit
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
What is the new price for fixed elevators? Professional improvement of the quality assurance of the elevator factory. Preferential activities are ongoing, welcome new and old customers to consult
Nas.Before using the machine, the staff should carefully check the hydraulic and electrical systems to ensure there is no leakage or bare leakage before using it.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment, fixed three-dimensional parking, and other places. So what is the new price for fixed elevators?
.Walking: assisted self-propelled, two wheel traction, self driving, and car modification.

The one-way valve is damaged. The one-way valve is designed to prevent oil return. If there is a problem, there will be some backflow, so it can be replaced at this time.
It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, the clothes will repeatedly slap the car paint, especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
Quality inspection report.To ensure excellent power supply at the installation site, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
Unscrew the screws on the dustproof hole on the outer side of the elevator flange, adjust the PCS system ring to align its side hole with the dustproof hole, and tighten with the hexagon socket. After that, remove the motor shaft key.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.

Convenient and efficient.Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers,NasTen ton lifting cargo elevator, and pull-out outriggers.
Chemical derusting is a type of derusting that uses acid to chemically react with the metal parts of the screw elevator to remove the rust products on the rust surface of the push rod. This type of derusting is mainly used for large mechanical screw elevators, the motor still operates with full load,NasLarge tonnage guide rail type cargo elevator, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated,NasElevating cargo elevator, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, adjust the PCS system ring to align its side hole with the dustproof hole, and tighten with the hexagon socket. After that, remove the motor shaft key.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding, the short circuit current is much larger than the normal working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
