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.
If the circuit of the device is not disconnected or lowered, for situations with large lifting loads and small lifting heights a lifting mechanism should be selected. For situations with small loads but large lifting heights, a lifting mechanism should be selected. According to the initial structure of the jacking, in order to meet the stability requirements, the size and lifting type of the oil cylinder are increased, and in order to achieve the same effective area as the jacking force, a lifting mechanism should be selected.
After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
.The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
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,NivohainFreight elevator type hydraulic lifting platform, 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, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
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.
There are two reasons for the sinking of the hydraulic cargo elevator table: on the one hand, and under high pressure or temperature, the volume will change, which is reflected in the lowering of the position on the table.
When 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 shaking
management.Lines of various safety equipment
The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, and should be stable at the maximum lifting height.
Hydraulic 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, 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, linkage, explosion-proof), 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.
After long-term use of the automatic lifting platform equipment it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply,NivohainScissor fork hydraulic lifting platform, and a small cross-sectional area of the power supply cable, in the hydraulic pipeline assembly line it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Many high-rise cargo transportation often requires the use of hydraulic cargo elevators or transport elevators, but in practical applications, 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 inquiries
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
Nivohain.Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
