SentesManufacturer of scissor liftNotes on the economic system

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.

Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the

Sentes.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, 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.

Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.

.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,SentesHydraulic small lifting platform, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.

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.

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.

Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.

It is prohibited to work on unstable structures (such as asbestos tile roofs). To prevent accidental boarding, warning signs should be hung at necessary locations of this structure.

technological innovation.The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on,SentesIndoor fixed hydraulic lifting platform, whether the three-phase electrical phase sequence is correct,SentesAluminum alloy hydraulic lifting platform, and whether the relay working indicator light is on.

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.

Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.

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.

Industry management.Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.

When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.

Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.

Sentes.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 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.

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.

Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.
