NXQ Series Accumulatorsare commonly used bladder-type accumulators in hydraulic systems. Below is an introduction from several aspects, including design features, application scenarios, technical parameters, and selection and installation:
I. Design Features
1. Compact Structure: Manufactured using seamless steel tube spinning technology, these accumulators are small in size, light in weight, and have low inertia, facilitating easy installation and maintenance.
2. Stable Performance: Compliant with the JB/T7036-93 "Technical Conditions for Hydraulic Accumulators" standard, they maintain stable performance under various operating conditions.
3. Reliable Sealing: High-quality sealing elements are used to ensure no leakage occurs during operation.
4. Wide Temperature Range: The bladder is filled with nitrogen gas, and the operating temperature range is typically from -10°C to +70°C, suitable for various environmental conditions.
II. Application Scenarios
NXQ Series Accumulators are widely used in the following fields:
1. Energy Storage: Store energy in hydraulic systems for release when needed, improving system response speed and efficiency.
2. Absorb Hydraulic Shocks: Installed at the outlet of hydraulic pumps or before actuators to absorb hydraulic shocks and pulsations in the system, protecting system components from damage.
3. Compensate for Leakage: Provide pressure oil when the system leaks to maintain stable system pressure.
4. Auxiliary Power Source: Serve as an auxiliary power source in applications requiring a large amount of oil in a short period.
III. Technical Parameters
The technical parameters of NXQ Series Accumulators vary by model. Below are some examples of common models' technical parameters:
【表格】
Model Nominal Pressure (MPa) Nominal Volume (L) Connection Method Weight (kg)
NXQ-L0.63/* 31.5 0.63 Threaded Connection 4.5
NXQ-L1/* 31.5 1 Threaded Connection 6
NXQ-L1.6/* 31.5 1.6 Threaded Connection 12.5
NXQ-L2.5/* 31.5 2.5 Threaded Connection 15
NXQ-L4/* 31.5 4 Threaded Connection 18.5
NXQ-L6.3/* 31.5 6.3 Threaded Connection 25.5
IV. Selection and Installation
1. Selection Basis:
• Choose the appropriate nominal pressure and nominal volume based on the system's operating pressure and flow requirements.
• Select the suitable model and connection method (e.g., threaded connection or flange connection) based on installation space and connection requirements.
2. Installation Precautions:
• Accumulators should be installed vertically with the bladder side facing upwards to ensure normal expansion and contraction of the bladder.
• Check the appearance and sealing performance of the accumulator before installation to ensure no damage or leakage.
• Use appropriate tools and fasteners during installation to ensure a secure and reliable connection between the accumulator and the system.
• Regularly check the pressure and sealing performance of the accumulator during use and promptly replace damaged components.
