Hanshan10 meteThere 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.
When using an electric mobile scissor lifting platform outdoors if the wind force exceeds level 5, please stop using it; When the lifting height exceeds 10 meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform
Hanshan.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.

. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, 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, throttle valve, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.

When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
In addition, the convenience of the layout is also a very important issue. For example, there may be layout issues when using a lifting mechanism. At this point, in order to facilitate the arrangement and prevent the hydraulic cargo elevator cylinder from being eroded by waves, a lifting structure should be selected to determine the installation position of the oil shoulder, as the lifting point of the bridge is not in a straight line during the lifting process. Therefore, during the lifting process of the cylinder, the connection between the two ends of the cylinder and other components must be hinged in the same square. In addition, the installation of the hydraulic cargo elevator cylinder must also be determined through comparison and calculation, the middle pin shaft type, or the head pin shaft type. The main advantage is that the effective area of the cylinder is large and the overall installation height is low. The disadvantage is that if the cylinder stroke is large, there may be stability issues with the cylinder, and the cylinder layout may be difficult. The main advantage of the hydraulic cargo elevator lifting mechanism is that it does not have a stable transmission installation frame for height measurement. Therefore, this form can be considered in places with large drops. The sudden deafness oil type on the head can reduce the installation height, but if it is too large, the oil cylinder will experience an increase in force due to the lifting height. Moreover, the higher the lifting height, the faster the increase in force, which is not suitable for the use of the oil cylinder. Therefore, when it is too large, the head pin type is not suitable. In order to comprehensively consider the height of the installation bracket and the force on the oil cylinder during the lifting process, an intermediate installation method can be considered, and the installation position can be set at an appropriate height according to calculations.
After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
How much is it.The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, speed regulation can change both the flow rate and the motor displacement.

The use of cleaning oil and the brand used in the system
Quality improvement.Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.
Therefore, maintaining the hydraulic cylinder is an important part of the entire hydraulic system maintenance. In addition, hydraulic cylinders are equivalent to the heart of the hydraulic system, making it difficult to repair heart problems. Therefore, maintenance of hydraulic cylinders should be cautious. Professional elevator manufacturers have advanced technology, strict testing, more affordable prices, and more discounts. Welcome to consult
