Zao QiangAutomatic hydraulic lifting platformWhat kind of benefits does the emergence of

and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve

The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, hydraulic control one-way valve throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, 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.

Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.

Zao Qiang.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. Professional elevator manufacturers and other special products, 20 year old brand, with price advantages and guaranteed quality

Remove the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap,Zao QiangSelf propelled hydraulic lifting platform, first remove the soil around the tank cap, loosen the tank cap, open the tank cap.

.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch it is easy for hydraulic cargo elevator manufacturers to cause this problem.

Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.

Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.

The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, government agencies, commercial stores, and the construction and decoration industry.

There are two reasons for the sinking of the hydraulic cargo elevator table: on the one hand, the hydraulic pressure is flexible, and under high pressure or temperature, the volume will change, which is reflected in the lowering of the position on the table.

An inverter can also generate high noise. When the power supply voltage is lower than 85% of the rated voltage, the short circuit ring of the iron core of the device breaks, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.

Quality management.The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.

The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.

Oil leakage from the oil cylinder: If it is a problem with the sealing ring,Zao QiangSelf hydraulic lifting platform, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.

When disassembling and adjusting the reverse organization of the equipment,Zao QiangHydraulic lifting platform, and its meshing surface is not less than 70%. The meshing gap should be appropriate.

Inspection basis.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.

Ensure a good power supply at the installation site, install a separate distribution box, and when using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the leakage switch should be compatible with the frequency converter when selecting it.

When using hydraulic elevators, the main causes of noise are mechanical mechanism failures, hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.

Zao Qiang.Hydraulic cargo elevators have been used in some high-altitude operations in recent years and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
