GujiaoCustomized hydraulic lifting platformTeach you how to maintain

The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.

Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.

Gujiao.Hydraulic oil is the blood of the cargo elevator. Maintaining the cleanliness of hydraulic oil is an important factor in extending the hydraulic freight elevator. How to maintain the cleanliness of hydraulic elevators?

The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.

.Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.

Aluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material,GujiaoHydraulic mobile lifting platform, which is lightweight and has a more beautiful appearance. The disadvantage is that it has a light load capacity and is only suitable for simple high-altitude maintenance work, and can only provide support for 1-2 people.

Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles pits, paint leakage, which is a qualitative problem and easy to arrange. The disadvantage is that the effective use of the oil cylinder can lift the same load, and the oil cylinder of the lifting mechanism is much larger than that of the lifting mechanism.

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,Gujiao10 meter hydraulic lifting platform, 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.

Bidding.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.

Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.

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.

The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.

supply.Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, and alignment points, and confirm that the foundation meets the requirements before construction.

Lift and move horizontally with load to return to the loading position. For the transportation time of each item, such repeated cycles are called cycles.

The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.

Gujiao.Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation,GujiaoMast type aluminum alloy hydraulic lifting platform, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.

Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.

When installing, 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.
