There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, and the pipelines should avoid dead bends as much as possible.When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.Cohen Nipps,All high-altitude operations must first build scaffolding or take measures to prevent teams from falling before boarding the vehicle bridge.Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.Ponte do Lima,I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, and are mainly used in factories government agencies, commercial stores, the short circuit ring of the iron core of the device breaks, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.Many high-rise cargo transportation often requires the use of hydraulic cargo elevators or transport elevators, there is a strange phenomenon that more people choose to use hydraulic cargo elevators than elevators. Why is this? We are a long-term elevator manufacturer that welcomes inquiriesWhen the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shakingindex,Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point,Cohen NippsHydraulic lifting platform 18 meters, it is necessary to exhaust the air in a timely manner.

Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.Manufacturing cost,A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.In addition, the convenience of the layout is also a very important issue. For example, in areas with large or high waves, there may be layout issues when using a lifting mechanism. At this point, in order to facilitate the arrangement and prevent the hydraulic cargo elevator cylinder from being eroded by waves,Cohen Nipps10 meter hydraulic lifting platform, a lifting structure should be selected to determine the installation position of the oil shoulder, as the lifting point of the bridge is not in a straight line during the lifting process. Therefore, during the lifting process of the cylinder, the connection between the two ends of the cylinder and other components must be hinged in the same square. In addition the installation of the hydraulic cargo elevator cylinder must also be determined through comparison and calculation, whether it is the tail lifting ear type, the middle pin shaft type, and the overall installation height is low. The disadvantage is that if the cylinder stroke is large, there may be stability issues with the cylinder, and the cylinder layout may be difficult. The main advantage of the hydraulic cargo elevator lifting mechanism is that it does not have a stable transmission installation frame for height measurement. Therefore, this form can be considered in places with large drops. The sudden deafness oil type on the head can reduce the installation height, but if it is too large, the oil cylinder will experience an increase in force due to the lifting height. Moreover, the higher the lifting height, the faster the increase in force, which is not suitable for the use of the oil cylinder. Therefore, when it is too large, the head pin type is not suitable. In order to comprehensively consider the height of the installation bracket and the force on the oil cylinder during the lifting process, and the installation position can be set at an appropriate height according to calculations.Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.Cohen Nipps,The installation personnel should confirm and count the equipment details,Cohen NippsSmall hydraulic lifting and leveling, confirm that there are no omissions in the shipped equipment details, check if the tools are complete and ensure the smooth progress of the installation process.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.Remove the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.
