　　Moisture and dust prevention in electrical systems

　　Electrical system moisture ａnd dust protection

　　Moisture and dust-proof electrical system

1. Heat dissipation of electrical control cabinet: High temperature is accompanied by high humidity, and the electrical control cabinet should be isolated from high-temperature dust sources as much as possible. If the ambient temperature is too high, it is necessary to open the electrical cabinet ventilation or cooling equipment to ensure that the internal temperature does not exceed 40 ℃, and to strictly prevent electrical components from aging or losing control due to high temperature.

1.Cooling of the electrical control cabinet: In high-temperature ａnd high-humidity conditions, the electrical control cabinet should be isolated from the source of high-temperature dust. If the ambient temperature is too high, the ventilation or cooling equipment of the cabinet should be turned on to ensure that the internal temperature does not exceed 40℃, ａnd to prevent electrical components from aging or malfunctioning due to high temperatures.

1. Heat sink for electric control cabinet: High temperature usually comes with high humidity, so electric control cabinet needs to be arranged as far away as possible from high heat sources and dust sources. If the ambient temperature is too high, it is necessary to open the ventilation device or cooling / underheating device for the cabinet, ensure that the temperature inside the cabinet does not exceed 40 ° C, and at the same time strictly avoid the condition of electrical components aging or loss of functional control due to high temperature.

2. Anti condensation treatment: During the rainy season or shutdown state, pay attention to checking the sealing of the electrical control cabinet, and if necessary, turn on the moisture-proof heating device inside the cabinet to prevent the circuit board from being affected by moisture and short circuiting.

2. Anti-condensation treatment: During the rainy season or when the equipment is shut down, pay attention to checking the sealing condition of the electrical control cabinet. If necessary, activate the dehumidification heating device inside the cabinet to prevent the circuit boards from getting damp ａnd short-circuiting.

Anti-condensation treatment: In the rainy season or during equipment downtime, pay attention to check the sealing of the electric control cabinet; If necessary, turn on the anti-humidity heating device inside the cabinet, in order to prevent the electric circuit board from getting wet leading to circuit breakage.

　　Transmission and lubrication system

　　Transmission ａnd lubrication system

　　Drive and lubrication system

1. Oil and oil level: Lubricating oil viscosity is prone to decrease at high temperatures. Please check the oil level and quality of the gearbox and gearbox, and replace them with summer specific high viscosity gear oil if necessary. Ensure smooth oil circulation to avoid oil seal leakage or gear wear caused by high oil temperature.

1. Oil quality ａnd oil level: The viscosity of lubricating oil tends to decrease at high temperatures. Please check the oil levels ａnd quality of the gearboxes ａnd reducers. If necessary, replace with high-viscosity gear oil specifically for summer use. Ensure that the oil circulation is unobstructed to prevent oil seal leakage or gear wear due to excessively high oil temperature.

1.Tightly check the important positions: The phenomenon of expansion due to heat and shrinkage due to temperature change is easy to make the bolt loosen. Therefore, after stopping the machine (note to avoid burning) or periodically, it is necessary to check the tightness of the head flange, the connecting details of the screw and the safety device. When tightening the bolt/screw tightening, it is necessary to lubricate the lubricant withstanding high temperature 1000°C.

Please check the oil level and oil quality of the gearbox and transmission; If necessary, replace with high viscosity gear oil for summer. At the same time, it is necessary to ensure that the circulating oil line and the oil line cooling system are always transparent, avoiding the condition of excessive oil temperature leading to oil leakage or gear wear.

2. Key fastening: Thermal expansion and contraction can easily cause bolt loosening. Please stop the machine and check the fastening of the head flange, screw connectors, and safety devices in a hot state (pay attention to burns) or regularly.

2.Key Fastening: Thermal expansion ａnd contraction may cause bolts to loosen. Please stop the machine ａnd conduct a hot-state inspection (be cautious of burns) or perform regular checks on the fastening conditions of the machine head flange, screw connection components, ａnd safety devices.

2.Check the tightness of important parts: the phenomenon of expansion and contraction due to temperature can cause the bolt to loosen; Therefore, after stopping the machine, it is necessary to check the hot state of the equipment (attention should be paid to avoid burning) or periodically check the tightness of the starter flange, the screw connecting details and safety devices. The bolts need to be lubricated to withstand temperatures up to 1000 degrees C.
