Client Type Country Quantity Application Duration Result Highlight
Pumped storage power station CN 3units Used for gate hoist control in engineering fields such as water conservancy and hydropower, flood control and drainage, and river regulation 10years The design specification for the holding force of the core hydraulic hoist reaches 5000 kN, ensuring that the equipment has sufficient capacity to quickly and smoothly close the tailrace emergency gate under emergency conditions (such as unit failure or pipeline rupture), instantly cutting off the tailrace flow to prevent river water from flowing backward into the powerhouse, and ensuring the safety of the underground powerhouse and core units. Among the equipment inspected this time, the structurally complex gate slot cover plate has become the focus of attention. This cover plate integrates numerous precision devices. Through on-site measurements, it has been confirmed that the flatness error of the cover plate is strictly controlled within 0.05 millimeters per square meter as required by the design drawings, ensuring a seamless fit between the cover plate and the gate slot, thus laying a solid foundation for subsequent installation and commissioning.

Risk Items
Corrosion and fatigue risks (Piston rod pitting, plating peeling)protective measures
Enterprise Measure1. Surface protection: For marine climate or chemical environments, the piston rod is made of stainless steel (such as 316L) or coated with ceramic instead of ordinary chrome plating. 2. Dust protection: The exposed piston rod is equipped with a retractable dust cover (made of canvas or polyurethane) to prevent sand, gravel, and welding slag from damaging the plating. 3. Shutdown rust prevention: When the equipment is shut down for an extended period, the cylinder piston rod should be fully retracted or extended, and rust preventive oil should be applied to the surface of the rod.
Hydraulic shock and exhaust risk (Water hammer effect, cavitation)Debugging Standards
Enterprise Measure1. Exhaust operation: After installation, it is necessary to exhaust the air inside the cylinder chamber by repeatedly moving the piston slowly through the exhaust valve or by loosening the pipe joint. 2. Buffer adjustment: For high-speed and heavy-load hydraulic cylinders, the buffer clearance or buffer valve is preset before delivery to prevent the piston from hitting the cylinder head at the end of its stroke, which could cause severe vibrations. 3. Pressure step loading: During debugging, gradually increase the pressure from low to high (such as 30%, 60%, 100%), and observe for any creeping or abnormal noise.
Installation alignment risk (Piston rod binding, eccentric wear of guide sleeve)Work Instructions
Enterprise Measure1. Alignment: During installation, use a laser alignment instrument or a dial gauge to ensure that the coaxiality error between the centerline of the oil cylinder and the direction of load movement is ≤0.05mm per 100mm. 2. Flexible connection: Spherical bearings or joint bearings are used at the connection to compensate for accumulated installation errors. 3. Installation sequence: It is clear that the cylinder barrel should be fixed first, followed by connecting the load, and finally adjusting the buffer to prevent initial stress caused by forced assembly.
Material and heat treatment risks (Piston rod fracture, cylinder burst)source control
Enterprise Measure1. Material specification control: The piston rod must be made of high-strength quenched and tempered steel (such as 45# steel or 40Cr), and the cylinder barrel shall be made of precision cold-drawn tube (such as 27SiMn). Establish chemical composition testing for incoming materials. 2. Heat treatment process: The surface of the piston rod undergoes medium frequency quenching (hardness HRC55-60) followed by hard chromium plating (thickness ≥0.03mm). The inner wall of the cylinder barrel is honed to ensure a balance between surface hardness and core toughness. 3. Non-destructive testing: Conduct ultrasonic or magnetic particle flaw detection on the welded cylinder bottom and key stressed components to eliminate internal cracks.
Selection and matching risk (Insufficient thrust, excessive travel, incorrect installation method)Prevention and Control
Enterprise Measure1. Accurate calculation of load: Calculate the maximum pushing and pulling force based on the working conditions, and reserve a safety factor of 1.3-1.5 times to avoid selecting a "small horse to pull a large cart". 2. Stability verification: For oil cylinders with long strokes (more than 10 times the cylinder diameter), perform a stability check on the pressure rod to prevent the piston rod from buckling due to instability under pressure. 3. Confirmation of installation method: Based on the structure of the host machine, specify the installation method as hinged, flanged, or trunnion-mounted, and calculate the shear strength of the connecting pin shaft and the load-bearing capacity of the ear thread.
