Introduction to Limited-Torque Hydraulic Couplings

1. Advantages of the Limited-Moment Hydraulic Coupling
◆ To enhance the starting capability of squirrel-cage induction motors, the motor's peak torque can be utilized as the starting torque, thereby avoiding the inefficient mismatch phenomenon of "using a large horse to pull a small cart."
◆ Reduce the starting time of the electric motor and minimize the inrush current during startup.
◆ Prevent power overload and protect the motor and working machinery from damage caused by excessive load.
◆ Reduce vibration and impact during the startup process.
◆ In multi-machine drive systems, it ensures that motors start independently, enables power balancing, and provides a starting torque limit ranging from 1.2 to 1.6 times the rated torque.
◆ Simple in structure, reliable, free from mechanical wear, and requiring no special maintenance.
◆ Capable of working in a variety of harsh operational environments.

2. Application Scope of Hydraulic Couplings
Widely used in various mechanical equipment across industries such as power generation, steel production, metallurgy, mining, coal processing, building materials, chemical engineering, ports, lifting systems, transportation, and construction machinery. Examples include belt conveyors, scraper conveyors, chain conveyors, screw conveyors, bucket elevators, bucket wheel stacker-reclaimers, coal mills, ball mills, crushers, bridge cranes, gantry cranes, tower cranes, leather tanning drum machines, washing machines, wire-drawing machines, rubber mixing machines, boiler slag crushers, centrifuges, amusement park rides, and more.

3. Characteristics of Limited-Moment Hydraulic Couplings
(1) Types, varieties, and specifications of limited-torque hydraulic couplings:
◆ By transmission medium: available with mineral oil or water filling, both featuring identical axial installation lengths and fully interchangeable components.
◆ By drive type: the YOX series features an external impeller (pump wheel) drive, while the YOXn series is driven by an internal impeller (turbine).
◆ By cavity type: there is the single-cavity YOX series and the double-cavity YOXD series.
◆ According to the structural classification based on start-up time: YOP series with no rear auxiliary chamber; YOX series of standard type; YOXV series with extended rear auxiliary chamber; and YOXvvs series featuring an extended rear auxiliary chamber and enlarged side auxiliary chambers.
◆ By equipment transmission characteristics: there are the YOXP series with belt pulleys, and the YOXIIZ and YOXNZ series with brake wheels.
◆ By easily removable type: YOXA series coupling with elastic sleeve pin design.

(2) Characteristic Curve (at a liquid filling rate Qc = 80%)
◆ The combined starting characteristic curve diagram of the electric motor and hydraulic coupling is shown in Figure 1.
◆ The original characteristic curve diagram of the hydraulic coupling's starting process is shown in Figure 2.
◆ The start-up time and process curves for the motor and hydraulic coupling are shown in Figure 3.
(3) Designation and Meaning of Hydraulic Coupling Codes
The code and identification of the hydraulic coupling shall be represented by Chinese Pinyin letters according to GB/T 5837-2008 "Types and Basic Parameters of Hydraulic Couplings."
1. Hydraulic couplings driven by an external power source and using mineral oil as the working medium do not require any codes or letters for identification.

Main foundry business scope and capacity:

To cast 104-based aluminum alloy parts, HT150-250 cast iron parts, 45# steel-based various types of carbon steel castings. The production capacity of aluminum castings is 100 tons/month, and the production capacity of cast iron and steel parts is 100 tons/month. The company can provide customers with one-stop service of rough casting and processing. Mass production using die casting, small batch parts using sand casting.

Among them, cast steel (alloy steel) is the optimization and reorganization of the company's casting division and the original branch (Yunan Zhongxing Wear-resistant Materials Co., Ltd.) in 2023, fully combining the advantages of both parties, that is, the combination of technological innovation and mature management, aiming at common customer terminals, reducing marketing costs, and also allowing customers to obtain the convenience of one-stop after-sales service. The main products are related to electric power, mining, cement, ports, waterway dredging metal wear-resistant parts, product materials are metal matrix ceramic composite materials, high chromium, high manganese, alloy steel and so on.
