Requirements for the working environment of pneumatic balancers

Gas source conditions

Clean and dry: Pneumatic balancers require clean and dry compressed air as a power source. Moisture, oil, and impurities in the air can damage internal components and affect performance.

Stable air pressure: The air pressure needs to be stable within the range required by the equipment. Fluctuations in air pressure can affect the load balancing effect and even damage the equipment.

Adequate flow: Compressed air needs to provide sufficient flow to meet the operational requirements of the equipment.

ambient temperature

Suitable range: Pneumatic balancers typically operate at ambient temperatures ranging from -20 ° C to 80 ° C, and exceeding this range may affect performance and lifespan.

Avoid extremes: Extreme cold or hot environments may cause issues such as seal aging and material deformation.

Humidity conditions: Pneumatic balancers are suitable for use in environments with low relative humidity. High humidity may cause internal parts to rust, affecting performance.

application

In situations where high positioning accuracy is required: Pneumatic balancers have suspension characteristics and can manually lift loads to designated positions within the suspension range, making them particularly suitable for use in situations with high positioning accuracy.

In special fields such as clean rooms, laboratories, chemical plants, food workshops, etc. that require clean and environmentally friendly tools, pneumatic balancers driven by gas sources can be used, and they have certain explosion-proof functions.

High frequency operation scenarios: The pneumatic balancer uses a pneumatic motor, so there is no need to worry about the motor burning out after long-term use. It can operate at high frequencies 24 hours a day without interruption, which is suitable for high-frequency operation scenarios and can improve work efficiency.

Principles for selecting electrical components for pneumatic balancers

Selection of pneumatic components

Pressure reducing valve: To ensure load balance, the pressure of the pressure reducing valve needs to be adjusted according to the weight of the load. If the pneumatic pressure reducing valve is not of high flow rate, large exhaust volume, and high precision, it may result in slow cylinder piston speed due to low supply flow rate, long time for the system to reach the equilibrium point, slow piston movement due to low exhaust flow rate, and low precision causing the load to be unable to stop or even shake.

Directional valve: The lifting and lowering of the load is controlled by a handle, and a pilot pneumatic three position four-way directional valve is used to achieve the gas supply and exhaust function of the cylinder.

Overflow valve: It is designed to balance the load.

Throttle valve: Ensure that the pilot control valve is in the neutral position when there is no load.

Selection of safety protection components

Pneumatic directional valve: When the gas source is suddenly interrupted or the air supply is insufficient, causing a sharp drop in air pressure, the pneumatic directional valve will close in time. The pressure maintaining gas inside the miniature gas storage tank will support the slow descent of the robotic arm to protect the personal safety of the operator.

Emergency stop valve: An emergency stop valve should be installed on the pneumatic balancer to quickly cut off the gas source and stop the equipment operation in emergency situations.
