Hydraulic Prop Test Bench For Loader
1. Based on the Ministry of Coal Industry's MT119-85 "Type Test Specifications for Mine Hydraulic Prop Valves" and "Mine High-Pressure Hose" standards, this unit uses emulsion and hydraulic oil as working fluids. Its key performance parameters are safe and meet the requirements for testing and adjusting mining hydraulic products and components.
2. A manual reversing valve eliminates the traditional stop valve, providing easy and reliable operation, durability, and improved overall stability.
3. The test bench utilizes only domestically produced standard hydraulic components for easy maintenance.
4. This unit features rapid filling and automatic slow pressurization, improving testing speed and stability.
Hydraulic Prop Test Bench For Loader：
Hydraulic Prop Test Bench For Loader is a unique trying out tools designed in accordance to the Chinese coal enterprise trendy "MT112.1-2006 Single Hydraulic Prop for Mining", which is often used for manufacturing acceptance, every day preservation and commissioning, and overall performance trying out of single hydraulic props for mining.
Technical Parameters and Selection Recommendations:
1. Typical Model Parameters
Hydraulic System: Motor energy 2.2-5.5kW, oil pump waft 15-30L/min, rated stress 25-31.5MPa, working medium 46# anti-wear hydraulic oil.
Emulsion System: Rated stress 40-75MPa, most stress 60-80MPa, working medium 3-5% emulsion, stress detection accuracy 0.25%FS.
Press Specifications: Vertical press most load potential 1000kN, horizontal press 500kN, cylinder stroke 600-700mm.
2. Selection Key Points
Testing Requirements: Select the press kind based totally on the assist specs (such as cylinder diameter and stroke). For high-frequency checking out scenarios, a laptop built-in device is recommended.
Environmental Adaptability: The take a look at bench operates in an ambient temperature vary of -20°C to +70°C, with a humidity ≤85% RH, appropriate for the complicated prerequisites of underground coal mines. Extended function: If you want to discover massive aspects such as hydraulic supports, supply precedence to fashions that aid dual-media hydraulic systems.

Application Scenarios:
1. Coal Mine Production and Maintenance
Pillar Acceptance: New pillars should bear stress checking out on a check bench earlier than leaving the manufacturing facility to make sure that the preliminary assist pressure and working resistance meet diagram requirements.
Periodic Maintenance: According to the Coal Mine Safety Regulations, underground pillars have to bear renovation and strain checking out after greater than eight months of use. The take a look at bench can shortly affirm the pillar's sealing and pressure-bearing capacity, figuring out faults such as leakage and inadequate pressure.
Fault Diagnosis: The support's anti-slip overall performance is examined by means of simulating running prerequisites with altering coal seam inclination. Continuous reversing valve operation checks are carried out to confirm the sturdiness of seals.
2. Equipment Development and Quality Control
New Pillar Development: The overall performance parameters of new pillars, such as suspended and double-telescopic suspended, are proven thru simulated working circumstance testing.
Hydraulic Component Production: The sealing of hydraulic assist columns, jacks, and different aspects is examined to make sure product quality.
Standard Compliance Verification: Equipment complies with enterprise requirements based totally on requirements such as MT312-2000 and MT550-1996. three Cost Reduction, Efficiency Improvement, and Production Safety
For example, a coal mining employer used scrapped tools to create a customized single-unit hydraulic prop strain checking out platform. Using an emulsifier pump to join the props for strain testing, this platform extended checking out effectivity via 30%, decreased protection expenses with the aid of 20%, and eradicated the threat of repeated handling.
Data-driven decision-making: A laptop machine files historic prop take a look at data, offering a foundation for optimizing upkeep cycles and managing spare parts.
