When we normally use hydraulic lifts, we must always check, maintain and maintain them. This will not only extend the service life of the hydraulic lifts, but also make them more powerful when working! For example, the drive section should be sufficiently lubricated. For oil, the wearing parts must be inspected, repaired or replaced frequently. The mechanical bolts, especially the parts that often vibrate, such as slewing rings and lifting arm connecting bolts, should be inspected for looseness. If loose, they must be tightened or replaced. Below, we first look at the maintenance requirements for hydraulic lifts:
1, daily maintenance (per shift).
2. After the elevator has operated for 1500 hours, minor repairs are made to the mechanical and electrical systems.
3. After the lift has operated for 5,000 hours, the mechanical and electrical systems are repaired.
4. After the elevator has operated for 10,000 hours, the mechanical and electrical systems are overhauled.
Next, we talk about the maintenance and maintenance of hydraulic lift machinery and equipment:
1. The brakes of various agencies should always check and adjust the clearance between brake shoes and brake wheels to ensure flexibility and reliability. On the friction surface, there should be no dirt, dirt must be washed off with gasoline or thinner.
2. Lubrication and hydraulic oil of various parts such as gearboxes, transmissions, and external gears are performed according to the requirements in the lubrication table.
3. Attention should be paid to checking whether there are broken wires and loose strands in the wire ropes of various departments. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of wire ropes should strictly comply with the provisions of GB5144-85.
4. Check the connection of each department frequently and tighten it if loose. The body connection bolts shall be checked for tightness when the body is under pressure (rotary arms may be used to create compression). All connecting shafts must have cotter pins and must be fully opened.
5. Regularly check whether the operation of each institution is normal and whether there is noise. If any malfunction is found, it must be promptly removed.
6. When installing, disassembling and adjusting the rotary mechanism, it is necessary to ensure that the centerline of the reducer of the rotary mechanism is parallel to the centerline of the gear, and the mating surface is not less than 70%, and the meshing clearance should be suitable.
7. Always check all wires and cables for damage. Should be timely dressing and replacement of the damaged part.
8. If the motor is overheated, stop it in time and continue to run after troubleshooting. The lubrication of the motor bearing should be good.
9. Each part of the brush, the contact surface should be kept clean, adjust the brush pressure, so that the contact area is not less than 50%.
10. Each control box, distribution box, etc. are often kept clean, and dust on electrical equipment is cleaned in time.
11. The opening and closing of the contacts of the trip switch of each safety device must be reliable, and the contact arc pits should be polished in time.
The LED flood light outdoor adopts a non-stroboscopic LED drive scheme. The large-size LED chip outputs a luminous flux of 120LM/W through the PC optical lens. It will not flicker when taking pictures, and it will not hurt the eyes. It is environmentally friendly and energy-saving. The stadium light adopts the silicone potting process to achieve waterproof IP67. TThe stadium light adopts the silicone potting process to achieve waterproof IP67. The LED flood light body is made of aviation aluminum through die-casting process. The 19 heat dissipation ribs with a height of more than 30mm can quickly release the heat generated by the LED and ensure the Floodlight with long life.
