Leak Test Bench
1.According to the MT119-85 "Test Specification for Mining Hydraulic Support Valve Types" and "Mining High Pressure Rubber Hose" standards of the Ministry of Coal, emulsion and hydraulic oil are used as working media, and the main performance parameters are safe and meet the testing and tuning of mining hydraulic products and hydraulic components.
2 . The manual directional valve operation eliminates the original shut-off valve, making it easy, reliable, durable, and improving the stability of the entire machine.
3. All test benches use standard hydraulic components for easy maintenance.
4. This machine has fast liquid injection and automatic slow pressure boosting functions, which improve the testing speed and stability.
As the core tool for detecting mining hydraulic equipment, Leak Test Bench is application scenarios cover multiple key aspects such as coal mine production, equipment maintenance, and safety supervision.
Application scenarios:
1. Coal mine production site
Application scenario: Regular inspection and maintenance of hydraulic supports underground or on the ground in coal mines.
Requirement background: Three purpose valves (safety valve, one-way valve, unloading valve) are the core components of hydraulic supports, and their performance directly affects support safety.
Typical operation:
Safety valve setting pressure test: Ensure that the valve body automatically opens when overpressure occurs to prevent bracket damage.
Sealing test: Verify the sealing performance of the valve body under high pressure to avoid accidents caused by hydraulic oil leakage.
Advantages:
Portable design (some models): supports rapid on-site inspection underground, reducing equipment disassembly and transportation time.
Multi interface parallel testing: Simultaneously testing multiple three-way valves to improve maintenance efficiency.
2. Hydraulic equipment maintenance workshop
Application scenarios: Factory repair, performance retesting, and quality acceptance of three-way valves.
Requirement background: The repaired three-way valve needs to undergo strict testing to ensure that it meets the factory standards.
Typical operation:
Measurement of opening and closing pressure: Verify whether the opening and closing pressure of the valve body meets the design parameters.
Durability testing: Simulate long-term high-pressure working environment to test the fatigue life of the valve body.
Advantages:
High precision pressure control: Achieving an accuracy of ± 0.5% through a closed-loop system to meet the requirements of precision detection.
Data traceability function: Automatically generate test reports and record performance comparisons before and after maintenance.
3. Hydraulic equipment manufacturing enterprises
Application scenario: Quality control and factory inspection in the production process of three-way valves.
Requirement background: Ensure that each batch of products meets industry standards (such as MT419-1995 "Valves for Hydraulic Supports").
Typical operation:
Full performance testing: including sealing, flow characteristics, pressure response time, etc.
Sampling inspection: Conduct random sampling of batch products to verify production consistency.
Advantages:
Automated process: Reduce manual intervention, improve detection efficiency and consistency.
Compatibility extension: Supports quick switching testing of different valve body models.
4. Safety supervision and third-party testing agencies
Application scenarios: Safety certification, accident investigation, and technical appraisal of coal mining equipment.
Requirement background: Conduct compliance checks on in use equipment in accordance with national standards.
Typical operation:
Destructive testing: Conduct ultimate pressure testing on suspected faulty valve bodies to analyze the cause of failure.
Standard compliance verification: Compare test data with industry standards and issue authoritative reports.
Advantages:
High reliability design: meets the requirements of long-term continuous testing and ensures the credibility of the results.
Regulatory support: Built in industry standard parameter library, simplifying compliance verification process.
