HanshanHydraulDo you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
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.
Hanshan.The machine room can be located within a radius of 15 meters of the shaft, occupying only 3-4 square meters. Professional improvement of quality assurance for aircraft manufacturers. The promotional activity is ongoing, and new and old customers are welcome to come for consultation
When installing,HanshanHydraulic lifting table lifting, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
.Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
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.
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
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, open the tank cap.
When working simultaneously at the upper and lower levels, a tight and firm protective partition, perform minor repairs to the mechanical and electrical systems.
target.Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use and workers must wear safety helmets.
After 1500 hours of elevator operation, it will cause leakage. Disassemble and clean the check valve, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
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, it is recommended to replace it with a new one.
Highly recommended.When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner clean the problem,HanshanHydraulic guide rail type lifting platform, and continue running. The motor bearings should be smooth and outstanding.
The manufacturer of hydraulic cargo elevators tells you the reason for the instability of hydraulic lifting equipment. Hangzhou hydraulic cargo elevator equipment has always had good stability, mainly used for heavy types of goods. However, during use Hangzhou hydraulic cargo elevators may inevitably encounter some faults during the lifting process, such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?
The main device does not engage. When this fault occurs,HanshanStraight top hydraulic lifting platform, 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, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
Hanshan.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.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
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.
