GujiaohydrauliElectrical 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, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.
Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location,Gujiao10 meter hydraulic lifting platform, which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.
Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.
.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,GujiaoHydraulic lifting platform, 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.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.
The contact of the travel switch must be firmly opened and closed,GujiaoHydraulic electric lifting platform, and the contact crater should be polished in a timely manner.
The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
If working on a grid like platform, wooden boards should be laid to prevent tools and equipment from falling.
The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
High quality brand.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, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Remove the hydraulic oil tank filler cap, 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, 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, and the construction and decoration industry.
Convenient and efficient.Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than 50%.
There are two reasons for the sinking of the hydraulic cargo elevator table: on the one hand, the hydraulic pressure is flexible, and under high pressure or temperature, the volume will change, which is reflected in the lowering of the position on the table.
The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
Gujiao.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, heat dissipation, separation of air contained in oil and elimination of foam.
This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.
