What are the precautions for the use of hydraulic storage tank lifting equipment?

1. Hydraulic jacks cannot be used as permanent support equipment. For long-term support, the support part should be added under the heavy object to ensure that the hydraulic jack is not damaged.

2. If only one hydraulic storage tank lifting equipment is used to lift one end of the heavy object, the hydraulic storage tank lifting equipment should be placed on the symmetrical axis of the heavy object, and the long direction of the hydraulic jack base and the easy toppling of the heavy object should be made. the same direction. If two hydraulic jacks are used at one end of the heavy object, the direction of the base should be slightly symmetrical and placed on both sides of the symmetrical axis of the heavy object.

3. When two or more hydraulic storage tank lifting equipment are used to lift at the same time, they must be commanded, coordinated, and lifted at the same time.

4. Hydraulic storage tank lifting equipment should be stored in a dry and dust-free place. It is not suitable for use in workplaces with acid, alkali and corrosive gases, and it should not be placed outdoors in the sun and rain!

What are the structural parts of hydraulic storage tank lifting equipment?

The hydraulic storage tank lifting equipment is a piston type lifting equipment, consisting of a hydraulic control cabinet (pumping station), the main bearing of the high-pressure oil pipe, the accessories of the hydraulic pump system, the oil control valve, the piston jack, the ring wire rope hanger, and the pumping station by two independent Composed of a hydraulic lifting unit and a centralized electrical control cabinet, it can serve the lifting of two 10000m³ tanks at the same time. Each 10000m³ tank is equipped with 20 jacks. The total composition of the hydraulic oil pipe is distributed in two stages, and then the hydraulic oil is sent to the hydraulic jack. Short construction period, low cost and good economic benefits are its significant advantages.

What should be paid attention to before using hydraulic storage tank lifting equipment?

1. Before lifting, put the slotted end of the handle into the oil return valve stem, and tighten the oil return valve stem clockwise.

2. The handle of hydraulic storage tank lifting equipment is inserted into the handle hole and pressed up and down, and the piston rod will rise steadily to lift the heavy object. Due to the limiting device in the jack, it will not rise when it reaches a certain height.

3. To lower the piston of hydraulic storage tank lifting equipment, just use the slotted end of the handle to slightly loosen the oil return valve rod counterclockwise (no more than 2 turns), and the piston rod will gradually descend. If there is a load, the oil return valve stem should not rotate too fast, otherwise it will be dangerous if the descending speed is too large.

●Safe operation code of hydraulic jack

●Precautions for the use of hydraulic jack

●How to repair and maintain hydraulic roof in daily use

Safe operation code of hydraulic jack

1. Hydraulic lifting equipment must be operated by specialized operators;

2. Ground wire must be installed for hydraulic pump station;

3. Check whether motor is rotating in pump indicated direction after startup; motor for this equipment is step-down startup with six second interval. Supply oil for jack after full start of the motor; exhaust air in system via exhaust valve before lifting;

4. Rated pressure for hydraulic system is 25Mpa and pressure indication of pump station pressure gauge cannot exceed 26Mpa;

5. Check clamp block of upper and lower clamps for slip during jack lifting. If block teeth are filled with foreign matters, clean on time and clean the taper sleeve outside block. Grease the taper surface to reduce sliding friction between taper surface and block arc; if teeth shaped surface is severely worn more than 0.4mm, replace block on time. Remove upper and lower clamps and clean after each project. Check wear condition and replace when necessary;

6. Check whether exhaust valve is closed before lifting;

7. Increase pressure slowly during adjustment;

8. System pressure can be at 28Mpa for a short time. Avoid long-term operation for damaging the system;

9. Do not crash high pressure oil pipe with hard objects. Avoid welding slag scorching. Replace high pressure rubber pipe for loss on time;

10. Release the pressure in system via exhaust valve when replacing hydraulic components;

11. Lift jack for a few millimeters when loosening clamp. Unload lower clamp and loosen it;

12. Loosen all lower clamps for butt joint and check; if looseness is inadequate, do not descend jack for opposite joint to avoid lower clamp damage;

13. Adjust pressure precisely when jack is ascending or descending in place. Do not put solenoid valve at neutral position to avoid instantaneous overvoltage;

14. Long-term overload operation is prohibited;

Precautions for the use of hydraulic jack

1. Hydraulic oil level in oil tank should be regularly maintained to normal level. Due to large capacity chamber of piping and hydraulic cylinder, it is mostly required to fill adequate hydraulic oil. After startup, hydraulic oil enters pipeline and cylinder, oil level decreases and filter even shows above oil level. Replenish hydraulic oil once again. It’s inevitable that hydraulic oil has loss during use, therefore, observe oil level regularly and replenish on time to maintain it at the middle position of level meter;

2. Hydraulic oil shall be kept clean always. Use oil filter vehicle when filling hydraulic oil with filtration precision below 30υm;

3. Replacing cycle for hydraulic coil is one year for normal operation;

4. Discharge all residual oil in tank when replacing hydraulic oil and refill after cleaning the tank. Filtration precision of new oil shall not be lower than precision of the system. Oil amount in tank shall be maintained within fixed level range;

5. Oil temperature shall be appropriate, not more than 60℃. Check for abnormal oil temperature rise. Start hydraulic pump and operate as required after oil temperature reaches 15 ℃ during winter;

6. Pay attention to the following for initial startup of hydraulic pump:

7. 1)     Hydraulic oil level in the tank shall be at the full position of vernier;

   2)     Check rotation direction of motor and it shall be clockwise seen from motor tail (arrow direction). If the direction id reversed, stop immediately and regain operation after handling;

   3)     Step up after 10 minutes’ idle operation of pump station;

8. Pay attention to check return oil filter. Replace cartridge for damage on time;

9. Before starting and stopping hydraulic pump, unload the overflow valve;

10. Spares for wear parts (seal ring, clamp block, etc.) shall be available at all times for timely replacement;

11. Set pressure of overflow valve cannot exceed maximum pressure of hydraulic system;

12. Check and maintain the jack before operation to ensure there is no oil leakage, clamp and the whole machine is in good condition;

13. When inserting lifting rod, the jack shall be loosened (loosening nuts at upper and lower clamps are screwed upward in place). Note that lifting rod and jack shall be almost concentric. Reset upper and lower clamps for normal operation and make the jack in operating state;

14. Prevent mud and sand from entering hydraulic rubber pipes during connection to avoid damaging hydraulic system and the jack;

15. Overpressure (overload) is prohibited during operation;

16. Lifting height shall exceed 20-30mm of coaming height and make jack piston at middle position for butt weld;

17. Make the jack at lifting state when descending the rod and oil pressure cannot be higher than that during lifting, that is to adjust oil pressure below that during normal lifting and then loosen lower clamp. After the jack is back stroke and lifted steel plate falls on newly surrounded plates, the jack bears no load. Loosen upper clamp and lifting rod descends;

18. According to actual ambient temperature, it is decided to use N46 anti-wear hydraulic oil for the system and mix of other grades is prohibited;

19. Clean and maintain the jack on time after one project, especially attachment at clamp block teeth. Replace for severe teeth wear and repair the replaced jack.
