Preload adjustment of ball screws is a key step to ensure their high precision, high rigidity and long life. The role of preload is to eliminate the gap between the ball and the raceway, reduce the reverse clearance (backlash), and improve the axial rigidity and vibration resistance of the system. However, excessive preload may cause heating, increased wear and even jamming, so the adjustment must strictly follow the technical specifications. The following are the detailed methods and precautions for preload adjustment: 1. Purpose of preload adjustment Eliminate axial clearance: Ensure that the screw has no empty stroke when moving forward and backward. Improve rigidity: Enhance the system's ability to resist deformation due to load changes. Extend life: Reasonable preload can evenly load the ball and avoid local wear.   Reduce vibration and noise: Reduce impact and abnormal noise caused by clearance. 2. Main methods of preload adjustment a. Double nut preload method (most common) Principle: Apply opposite axial forces through two nuts to squeeze the ball into contact with the raceway. Steps: Install double nuts: Install two ball nuts in reverse on the same screw shaft. Apply preload: rotate the two nuts to bring them closer together, compress the elastic element in the middle (such as a disc spring) or directly lock them through the thread. Adjustment method: Torque control method: tighten the nut to the specified torque value with a torque wrench (refer to the manufacturer's data). Displacement control method: measure the distance between the two nuts and adjust to the preset compression amount (usually 1%~3% of the lead). Lock the nut: use a locking washer or thread glue to fix the adjusted position. b. Shim adjustment method Applicable scenarios: single nut structure or occasions where the preload needs to be accurately adjusted. Steps: Add a shim between the nut end face and the mounting seat. Change the axial relative position of the nut and the screw by increasing or decreasing the thickness of the shim, and compress the ball and raceway. The preload needs to be tested repeatedly until the target value is reached. c. Spacer adjustment method Principle: add a spacer (sleeve) of a specific length between the double nuts, and control the preload by changing the length of the spacer. Advantages: High preload accuracy, suitable for equipment with high rigidity requirements (such as CNC machine tools). Steps: Measure the original spacing between the two nuts. Calculate the required spacer length based on the preload amount (usually the required compression amount = spacer length - original spacing). Install the spacer and lock the nut. d. Variable lead method (preload type ball screw) Principle: The manufacturer changes the lead of the ball circulation path to make the ball preload in the nut.   Features: Users do not need to adjust, and can obtain standard preload by direct installation (need to select according to the load). 3. Key parameters for preload adjustment Preload level: usually divided into light preload (C0/C1), medium preload (C2/C3), heavy preload (C5), which needs to be selected according to the load and accuracy requirements. Preload amount calculation: Preload amount ≈ 0.05~0.1 times the elastic deformation corresponding to the rated dynamic load. Empirical formula: preload = (5%~10%) × lead (refer to the manufacturer's manual). Preload detection indicators: Axial rigidity: The displacement after applying external force must be less than the allowable value (such as 1μm/N).   Reverse clearance: measured with a micrometer, the target value is usually ≤5μm. IV. Detection and verification after adjustment Torque test: Manually rotate the screw to feel whether the resistance is uniform and avoid local jamming. Use a torque meter to measure the driving torque and compare it with the manufacturer's recommended range (re-adjustment is required if it exceeds the limit). Reverse clearance detection: Fix the micrometer contact to the nut, move the screw in the forward and reverse directions, and record the displacement difference. Temperature monitoring:   Run without load for 30 minutes to check whether the temperature rise is normal (generally ≤40℃). V. Precautions Avoid over-preloading: Excessive preloading will cause a sharp increase in friction heat, accelerated wear and even sintering. Lubrication management: After preload adjustment, it is necessary to add an appropriate amount of grease. It is recommended to use high-speed and high-load lubricants. Environmental adaptability: The preload amount needs to be re-checked in high or low temperature environments (affected by the thermal expansion coefficient of the material).   Regular maintenance: Check the preload status every 300-500 hours of operation and readjust it if necessary. VI. Common problems and solutions Problem 1: Large running resistance after preload adjustment Cause: Excessive preload or insufficient lubrication. Solution: Reduce the thickness of the gasket or the length of the spacer sleeve and increase lubrication.   Problem 2: The reverse clearance still exceeds the standard Cause: The nut is worn or the screw shaft is bent. Solution: Replace the nut, straighten the screw or replace a new screw.   Problem 3: Abnormal noise and vibration Cause: Uneven preload or broken balls. Solution: Readjust the preload and check the ball circulation system.     Through the above understanding of ball screw preload, if you want to learn more, please contact us, we are online 24 hours a day to serve you.

Due to its high strength, corrosion resistance and aesthetics, stainless steel is widely used in machinery manufacturing, architectural decoration, home appliances and other fields. However, its high hardness and strong toughness also make its bending process more challenging. ZYCO will introduce in detail how to use a bending machine to efficiently and accurately complete the bending process of stainless steel sheets. I. Characteristics and difficulties of stainless steel bending 1. Material characteristics - Stainless steel (such as 304, 430, etc.) has high hardness and high yield strength, and requires greater pressure when bending. - It has high resilience and is prone to angle rebound after bending, which requires compensation adjustment. - The surface is easily scratched, and attention should be paid to the contact protection between the mold and the plate. 2. Common problems - Rebound: The angle of the plate rebounds after bending, resulting in the actual angle being smaller than the target angle. - Cracking: If the bending radius is too small, the outer tensile stress is too large, which may cause edge cracking. - Surface scratches: The stainless steel surface is damaged due to improper mold or operation.   Ⅱ. Working principle of bending machine The bending machine applies pressure to the plate to make it plastically deform through the cooperation of the upper die and the lower die. The hydraulic or electric driven pressure system can accurately control the bending angle and depth. Key parameters: - Pressure (tonnage): Calculate the required pressure according to the thickness and material of the plate. - Bending angle: Achieved by adjusting the upper die descending depth or the lower die opening distance. - Bending radius: Determined by the R angle of the die, it must be greater than the minimum bending radius of stainless steel (usually 1-2 times the plate thickness). Ⅲ. Stainless steel bending operation steps 1. Preparation - Choose the mold: give priority to high-hardness molds (such as 42CrMo steel) to avoid mold wear and scratching the stainless steel surface. - Clean the plate: remove oil or impurities on the stainless steel surface to prevent indentation. - Calculation parameters: Determine the pressure (P) according to the plate thickness (T) and material: the empirical formula is (P = T*T*650 / V) (V is the lower die opening width), which is the bending pressure required for a 1-meter-long carbon steel plate, and stainless steel is twice that of a carbon steel plate. - Set the compensation angle (usually 1°~3° larger than the target angle to offset the rebound).   2. Adjust the equipment - Install the appropriate upper and lower molds to ensure centering. - Enter the parameters (pressure, angle, stroke) and try bending, observe the rebound amount and then fine-tune.   3. Bending operation - Align the stainless steel plate with the center line of the lower mold and fix the position. - Start the bending machine, slowly press the upper die down to the set position, and hold the pressure for 1~2 seconds to release the stress. - Bend step by step (such as multiple small angle bends) to avoid cracking caused by one-time forming.   4. Inspection and correction - Use an angle ruler to measure the bending angle and compare it with the target value. - If the angle is insufficient, increase the compensation value; if there is an indentation on the surface, check the mold finish or add a protective film.   IV. Precautions 1. Avoid surface damage - Apply a polyurethane protective film on the surface of the mold or plate. - Clean the mold regularly to prevent iron filings from scratching stainless steel. 2. Control the bending radius - The minimum bending radius of stainless steel must be greater than that of carbon steel. It is recommended to refer to the material manual (such as the R angle of 304 stainless steel ≥1.5T). 3. Lubrication and cooling - Apply special lubricants (such as chloride-containing stainless steel oil) when bending to reduce friction and heat accumulation. 4. Safe operation - Wear protective gloves and goggles to prevent cuts on the edge of the plate or debris from flying. - Check whether the hydraulic system pressure is stable before bending.   V. Solutions to common problems Excessive rebound: - Increase the compensation angle or use the "bend and then press back" process. - Choose a CNC Press Brake with compensation function.   Edge cracking: - Increase the bending radius or choose annealed stainless steel (such as 304 soft state). - Bend perpendicular to the rolling direction of stainless steel to reduce stress concentration.   Surface indentation: - Use polished molds or pad soft materials (such as PVC film) on the mold contact surface.   VI. Summary Stainless steel bending processing has high requirements for equipment accuracy, mold selection and operating specifications. By reasonably adjusting parameters, compensating for rebound in steps, and paying attention to surface protection, the quality of the finished product can be greatly improved. For high-precision requirements, it is recommended to use a CNC press brake to achieve automatic control of complex bending processes through programming.

As the global energy structure accelerates its transformation to clean and low-carbon, breakthroughs in new energy technology have become the core driving force for sustainable development. Whether it is solar energy, hydrogen energy or lithium battery manufacturing, the safe and efficient transportation of fluids is still a key link in the implementation of technology. With its unique advantages such as zero leakage, corrosion resistance and high stability, magnetic drive pumps are becoming the "invisible guardian" in the field of new energy, injecting double guarantees of safety and efficiency into the energy revolution.   I. Core application scenarios of magnetic drive pumps in the field of new energy 1. Liquid flow battery energy storage system: solving the problem of electrolyte circulation Liquid flow batteries (such as all-vanadium liquid flow batteries) store and release energy through electrolyte circulation, but electrolytes are often highly corrosive. Traditional mechanical pumps are prone to leakage due to seal failure, which brings safety hazards and environmental pollution. The magnetic drive pump adopts magnetic coupling technology and uses non-contact transmission between the inner and outer magnetic rotors to completely eliminate the risk of leakage of mechanical seals.   2.

They stably transport molten salt or thermal oil through high-temperature resistant alloys and dynamically balanced impellers.   4. Solar photovoltaic systems: efficient cooling solutions In photovoltaic systems, magnetic drive pumps can realize liquid circulation in cooling components such as water pumps and water tanks, thereby improving system efficiency, reducing maintenance costs, and avoiding leakage problems common to traditional pumps.   5. Wind energy: improving reliability in harsh conditions Magnetic drive pumps can be used as oil pumps or lubricant pumps in wind turbines to ensure reliable fluid delivery. Its leak-free design can significantly improve the operational stability of remote or offshore wind farms.   6. Hydrogen fuel cells: safe handling of hydrogen Hydrogen fuel cells require high-pressure delivery of liquid hydrogen and coolant. Traditional pumps have the risk of explosion due to seal failure, while the fully sealed structure and high pressure resistance (up to 25MPa) of magnetic drive pumps can safely handle flammable and explosive media.   II. Technical advantages and industry certification of magnetic drive pumps 1. Zero leakage design: Eliminate risks at the source. Magnetic drive pumps replace mechanical seals with magnetic transmission to prevent leakage of toxic and flammable media.   2. Improve energy efficiency: Reduce energy consumption and noise. Compared with traditional pumps, magnetic drive pumps reduce mechanical friction losses, reduce energy consumption by 15-20%, and minimize noise pollution.   3. Wide application: Adapting to diversified energy needs, magnetic drive pumps are widely used in energy fields such as solar energy, batteries, and wind energy to meet the needs of various clean energy technologies.   From liquid flow batteries to hydrogen energy systems, magnetic drive pumps are driving the safety and efficiency upgrades of the new energy industry.
