Belo HorizonteHydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing chemical filling, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, rotary table, steering tipping, telescoping), and with various ways (separate, it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
Materials enter the production line at one end of the factory building,Belo HorizonteImported hydraulic lifting platform, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.
Belo Horizonte.In winter, when working outdoors at heights below minus 10 degrees Celsius, heating rest areas should be set up near the construction area if necessary. Heating equipment should be managed by dedicated personnel and attention should be paid to fire prevention.
What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.
.The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, The hydraulic oil tank has more heat dissipation effect.
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.
The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, and simple maintenance compared to the scissor fork type elevator.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
How to maintain the cleanliness of hydraulic elevators. If more high-quality hydraulic oil is added, it can prevent oil changes or blockage of system components. However, these additives will lose their effectiveness after a period of time.
Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
Where is it.Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height,Belo HorizonteHydraulic lifting table, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
Lines of various safety equipment
Executive standard.The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.
Check valve leakage, oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.
Each brush should be kept clean on its surface, the hydraulic elevator may experience problems with the hydraulic pump motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
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 will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.
The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.
