The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, so 5366r/min was determined as the aging frequency.
Los Angeles.The wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the friction surface is rough, and the surface pressure condition is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other. The metal debris that falls off from the grinding process, in turn, acts as abrasive and continues to participate in friction, further accelerating the wear of the mating surface of the parts. Therefore, during the running-in period, it is easy to cause wear on components (especially the mating surface), with a fast wear rate. At this point, if overloaded, it may cause damage to the components and lead to early failures.
Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms,Los AngelesHydraulic boarding bridge mobile manufacturer, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.

It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.

Every customer pays attention to the price of elevators, so how does the manufacturer calculate the price of elevators? In general,Los AngelesScissor fork type self-propelled lifting platform, the manufacturer calculates the price of the elevator for customers based on the actual size, height, and carrying capacity of the on-site reserved opening provided by the customer Customers do not need to pay too much attention to the price difference between different elevator manufacturers when purchasing elevators,Los AngelesTractive hydraulic lifting platform, as the different materials used, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing, with the principle of getting what they pay for. Safety hazard elimination plan for lifting cargo elevators: When there is a malfunction or abnormal situation in the lifting cargo elevator, it should be immediately stopped from use. After eliminating the malfunction and accident hazards, it can be put back into use
Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.
Meticulous workmanship.The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component the vibration pickup point is set in a thick area in the middle of the component.
The driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, during normal operation, it is prohibited to use the emergency stop switch to stop the platform.
Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
When the lifting base plate descends, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.
?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, it shall order the immediate elimination of potential safety hazards in the production of construction elevators and cargo elevators discovered during the inspection. If safety cannot be guaranteed before or during the elimination of major production safety hazards, it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction.
