by a riverHousThere is noise inside the hydraulic cylinder. When replacing the hydraulic oil, 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,by a riverfork lifter, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible,by a riverHydraulic fixed lifting platform, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
The installation personnel should confirm and count the equipment details, 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.
by a river.The hydraulic pump also has an impact on the flow rate of hydraulic oil. If the hydraulic pump is used for a long time, it is also prone to problems. When the speed of the hydraulic lifting table slows down, it is necessary to check whether the oil supply of the hydraulic pump is firm and firm.
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.
.Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds 10 meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, various flat conveying equipment is often installed on the lifting platform as a connecting device for conveying lines at different heights. Usually driven by hydraulic pressure and reduce shaking.
The use of cleaning oil and the brand used in the system
A lifting platform is a lifting device that lifts people or goods to a certain height. When vertical conveying is carried out in logistics systems such as factories and automatic warehouses, it is called a hydraulic lifting platform. In addition to being used for transporting goods at different heights, it is widely used for high-altitude installation, maintenance, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the
Lets see.Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Click to view.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary,by a riverMovable hydraulic lifting platform, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner.
Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.
by a river.An inverter can also generate high noise. When the power supply voltage is lower than 85% of the rated voltage, 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.
Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
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 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm 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 is necessary to exhaust the air in a timely manner.
