●Safe operation code of hydraulic jack
●Precautions for the use of hydraulic jack
●How to repair and maintain hydraulic roof in daily use
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;
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;
Hydraulic oil shall be kept clean always. Use oil filter vehicle when filling hydraulic oil with filtration precision below 30υm;
Replacing cycle for hydraulic coil is one year for normal operation;
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;
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;
Pay attention to the following for initial startup of hydraulic pump:
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;
Pay attention to check return oil filter. Replace cartridge for damage on time;
Before starting and stopping hydraulic pump, unload the overflow valve;
Spares for wear parts (seal ring, clamp block, etc.) shall be available at all times for timely replacement;
Set pressure of overflow valve cannot exceed maximum pressure of hydraulic system;
Check and maintain the jack before operation to ensure there is no oil leakage, clamp and the whole machine is in good condition;
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;
Prevent mud and sand from entering hydraulic rubber pipes during connection to avoid damaging hydraulic system and the jack;
Overpressure (overload) is prohibited during operation;
Lifting height shall exceed 20-30mm of coaming height and make jack piston at middle position for butt weld;
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;
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;
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.

Rolling machine is a kind of equipment that uses working rollers to bend and shape sheet metal materials. It can shape parts with different shapes such as cylindrical parts and conical parts. It's very important processing equipment.
What are the precautions for using the rolling machine?
What are the structural characteristics of the rolling machine?
What cleaning measures are available for the rolling machine?
(1) Automatic center alignment.
Roll forming of the sheet metal is mainly completed by the rolling effect of the rolling machine. When the sheet is fed into the rolling machine, it must be ensured that the front edge of the sheet is parallel to the outer circumference of the roll, so that the rolled parts have high precision and high quality. The automatic center alignment process of the blade in the automatic feeding device is mainly completed by the servo motor driving the center alignment rod. Then the sliding device pushes the sheet to the feeding position of the rolling machine and waits for the sheet to be rolled.
Given the peculiarity of the plate shape, the vacuum suction receiving device is mainly used for plate transport. The plate rolling machine can roll plates of different sizes. Therefore, the position of the suction cups in the vacuum suction cup receiving device of the automatic feeding device must have a suitable adjustment function to be suitable for handling plates of different sizes.
(3) The speed and stability of the handling process.
In order to meet the working rhythm of the sheet metal bending machine and the safety of the handling process, the automatic feeding plate handling process should have better speed and stability to prevent overshooting and vibration during the handling process.
The automatic feeding device of the sheet bending machine is mainly composed of a sheet metal carriage, an actuator, a sheet metal transfer mechanism and an auxiliary mechanism. Sheet metal trolleys are used for storing sheet metal to be rolled. The main function of the actuator is to transport the sheet metal to be rolled up on the sheet metal trolley to the feeding platform. The transportation process of sheet metal is mainly applied to the Cartesian coordinate manipulator and vacuum suction cup receiving device. In industrial automation systems, it is often necessary to pick up and transport workpieces, and vacuum suction cups are widely used as vacuum manipulators.
1. Clean the components of the sheet metal rolling machine, especially the connection place;
2. When assembling the sheet metal rolling machine, the principle should be followed from the inside to the outside, first down and then up;
3. During assembly, the use of the same assembly tools or observe assembly work in the same orientation;
4. During the assembly process, the transmission should be carried out in strict accordance with the design drawings, and the dimensions and specifications should be strictly checked.
Tank advanced hydraulic jacks refer to the container used to store the oil required to ensure the operation of the hydraulic system. According to whether the liquid level of the fuel tank is connected to the atmosphere, the fuel tank can be divided into two types: open type and closed type. The hydraulic oil tank lifting device plays a vital role in the transportation of tank advanced hydraulic jacks.
Why are more and more people choosing hydraulic storage tank lifting equipment?
What are the characteristics of the overall construction of the type advanced hydraulic jack?
How does the type advanced hydraulic jack work?
1. The oil cylinder adopts a high-pressure hose, which avoids the common oil leakage phenomenon of traditional multiple hoses. The cylinder will return to its original state by its own weight;
2. The hydraulic cylinder stroke is different according to the width of the fuel tank plate, which can meet the one-step lift of each annular shell plate. Greatly reduce time waste;
3. The basic height of the hydraulic cylinder is subject to the width of the tank shell. It can be equipped with an automatic girth welding machine for inner girth welding;
4. Modular configuration, the number of jacking systems can be adjusted according to the size and weight of the tank;
5. High efficiency, it only takes about 15 minutes for each lift or drop;
6. It can be well-matched with our tank welding machine, which can greatly reduce labor costs and construction time.
