Lift Equipment Relay Application
Whether the hydraulic lift is manpower traction, assisted walking or all-electric self-propelled lift, etc., all need to be connected to the power supply to realize the lifting function of the lifting platform. The lift is the power supply link of the entire hydraulic lift system and the backbone of the whole machine. , is a channel component that converts electrical energy into kinetic energy, including power switches, electrical control components, motors, etc.
The transmission device is the connection and transmission link of the production machinery, which is located between the motor and the working machinery, such as the chain of the rail-type elevator, the wire wheel, etc.
The electric control part of the hydraulic lift can be designed according to the actual use requirements of users, such as: 380v for industrial electricity, 220v for lifting platform for home use, linkage rolling shutter door, remote control, explosion-proof motor and other settings, the whole machine is all controlled by safe voltage, and the design is reasonable In the automatic control, the probability of failure is reduced, and the safety insurance is better for the safe use of customers.
The relays used in the lifting platform equipment are the problems that should be paid attention to when the electronic control devices are connected to the relays.
The relay generally has an induction mechanism that reflects a certain output variable, and an actuator that can realize "on" and "off" control of the controlled circuit. The unloader is in the input part and output part of the relay, and the input quantity is coupled and isolated. , functional processing and an intermediate mechanism for driving the output part, a relay is a device that can generate a predetermined jump in one or more electrical output circuits when the current input meets certain specified conditions, and it is in the control circuit. In terms of function, it is equivalent to a "switch", but it is not operated by a person, but an automatic motion control element.
① Correctly connect the power supply. There are two types of AC power: 380v and 220v boarding bridges. Do not connect them wrongly.
②If the relay is directly welded on the printed board of the lifting platform, it is necessary to ensure that the lead wire of the relay can be inserted smoothly, so as to prevent the relay root from being affected by tension due to the over-tightening.
③To prevent the temperature from being too high during soldering, because the soldering temperature is too high, the relay coil and the terminal of the lifting platform may be de-soldered, which will affect the performance of the reed contacts, and may also cause the components to crack. The harmful substances infringe on the root of the relay.
