Through the rational planning of the structure of the low-speed centrifuge, the hygienic dead angle can be effectively eliminated. The transition of the structural parts is smooth, and the surface is polished. External structural components, fasteners, and rollers are made of stainless steel. The housing is a clamshell type, which allows for thorough cleaning of the interlayer space of the centrifuge housing without the need for a bowl ...

The working form of LS contactor: Generally speaking, after the contactor coil is energized, the entire coil current will generate a magnetic field, which will make the core inside have electromagnetic attraction to attract the core, and make their AC contactor ...

Power refers to the amount of work done by an object in a unit of time, i.e., power is a physical quantity that depicts how fast or slow work is done. The amount of work is constant, and the shorter the moment, the greater the power value. The formula for finding power is power = work/moment. Power is a physical quantity that characterizes the degree of work done fast or slow. Units made in the hour ...

1. As soon as the inverter of the heat exchange station is opened, the pressure transmitter jumps randomly; 2. In the water supply controlled by the inverter, the pressure transformer is used as the signal to collect the pressure, and the pressure transformer is interfered by the inverter; 3. When the inverter starts the motor, the voltage transformer signal is unstable ...

(1) This series is divided into two types: economic type and standard type, which can meet the requirements of different customers: Economical: 10/14/20/30 points (10/14 points with 2 built-in analog potentiometers), up to 70 points. Standard type: 20/30/40/60 point DR/DRT (2-axis position ...

(1) Tripping LS electric molded case circuit breaker basically involves the tripping unit in the process of practical application, and the tripping is generally a thermomagnetic tripping or electronic tripping, and we must also understand this different tripping method in advance. In practice the application ...

(1) When the inverter is connected to the power grid of large-capacity power transformer (more than 500kVA), perhaps the same power transformer is connected with a thyristor converter without using a commutation reactor, or when there is a switching capacitor bank for power improvement in the same power grid, an AC reactor or DC reactor should be equipped.

In the control circuit of low-voltage electrical appliances, there are simple low-voltage components such as: buttons, safe, etc.; There are also slightly messy low-voltage electrical control components, such as circuit breakers, touch devices, time relays, thermal relays and other simple components, which makes it necessary to diagnose and analyze the cause of the problem. ...

In general, the cage rotor motor will be planned according to the frequency conversion, and at the same time the inverter (Variable-frequency Drive, VFD) drag, in different load characteristics, it is necessary to select VFDs with different functions, so now we ask a question. Can VFD be used with ...

The peripheral equipment of the inverter mainly includes cables, contactors, air switches, reactors, filters, braking resistors, etc. Whether the selection of the peripheral equipment of the inverter is correct and suitable also directly affects the normal operation of the inverter and the service life of the inverter.

1. The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal (U, V, W) of the inverter, otherwise the inverter will be damaged. After wiring, it is necessary to clean the trivial wires, which may cause abnormalities, failures and problems, and it is necessary to always keep ...

Frequency conversion governor is the power frequency power supply (50Hz or 60Hz) into various frequencies of communication power supply, in order to complete the variable speed operation of the motor equipment, during which the control circuit completes the control of the main circuit, the rectifier circuit converts the communication power into direct current, and the output input of the DC center circuit to the rectifier circuit ...

(1) Tripping LS electric molded case circuit breaker basically involves the tripping unit in the process of practical application, and the tripping is generally a tripping method of thermomagnetic tripping or electronic tripping. In the process of practical application, if it is a ...

1. Low-voltage electrical appliances: refers to electrical appliances that play the role of on-off, maintenance, control or regulation in circuits with a rated voltage of 1200V and a rated voltage of 1500V and below. 2. Main electrical appliances: electrical appliances used to send control instructions in the automatic control system. 3. Fuse: ...

1. Energy consumption type This method is to connect a braking resistor in parallel in the DC circuit of the inverter, and control the on/off of a power tube by detecting the DC bus voltage. When the DC bus voltage rises to about 700V, the power tube is turned on, and the regenerative energy is passed into the resistor.

LS touchers are divided into AC touchers (voltage AC) and DC touchers (voltage DC), which are used in electricity, power distribution and consumption. Toucher broadly refers to the electrical appliances that use the current flowing through the coil to generate a magnetic field in industrial electricity, so that the contacts are closed, so as to control the load. ...

1. During the holiday, low temperature can easily cause the equipment to be damp, check whether the electrical equipment is dry, whether there is moisture and condensation; 2. Check whether the grounding wire is loose and whether the cable is damaged by rodents and insects; 3. Sort out the dust and oil stains, and inverter ...

1. Improper device: The motor is not concentrious with the equipment being dragged, resulting in excessive radial load on the motor, which eventually leads to metal exhaustion. When the radial load on the extension end of the motor shaft is too large, it will cause the motor shaft to have zigzag deformation in the radial direction. When the motor rotates, the shaft's ...

The wiring method of the circuit breaker has the front of the board, the back of the board, the plug-in type, the drawer type, if the user has no special requirements, they are supplied according to the front of the board, and the wiring before the board is a common wiring method. 1. Wiring method behind the board: The wiring feature behind the board is that the circuit breaker can be replaced or repaired, without wiring from the beginning.

Molded case circuit breakers are also known as equipment circuit breakers, all parts are sealed in plastic housings, auxiliary contacts, undervoltage trippers and shunt trippers are modular. Because of the very compact structure, the molded case circuit breaker is basically impossible to maintain. It is mostly manually operated, and the large capacity ...
