Zaleg szegerDoEach box, distribution box, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve,Zaleg szegerLogistics hydraulic lifting platform, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Zaleg szeger.Oil cylinder leaks. Long term use causes wear on the sealing ring in the oil cylinder and excessive oil leakage in the cylinder wall gap, resulting in the natural descent of the hydraulic cargo elevator. The sealing components need to be replaced immediately.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
.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,Zaleg szegerHydraulic lifting table lifting, 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.
Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.
Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements, and can be combined in any combination such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.
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.
There are two installation methods for hydraulic freight elevator oil cylinders: jacking and lifting. The difference between jacking and lifting is that the placement direction of the oil cylinder is opposite, 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.

Scheme customization.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)

Analysis project.The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
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
The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets electric or hydraulic lifting platform walking power systems, and universal ball countertops.
Zaleg szeger.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact,Zaleg szegerElectric hydraulic lifting platform, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.
