BotanzaCustomized hydraulic lifting platformWhat is the overall work method

The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile,BotanzaTwo ton hydraulic lifting platform, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.

Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal,BotanzaLarge hydraulic lifting platform, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.

Botanza.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

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 the speed can only be adjusted by changing the flow rate. For variable displacement motors, and should be stable at the maximum lifting height.

Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).

The hydraulic oil used in the system has the same brand, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.

Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve, etc. If there are problems the hydraulic valve should be cleaned or replaced in a timely manner.

Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.

Inspection requirements.The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.

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.

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, 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, 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.

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 standard.Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.

The load of goods and the tonnage of goods transported at once also affect the lifting speed. The optimal value for transporting goods on a lifting platform is speed. If it is too heavy, it will affect the speed. The above is the knowledge about adjusting the lifting speed of hydraulic cargo elevators, hoping to be helpful to everyone. Long term improvement: The manufacturer has a complete range of products, excellent quality, and discounted prices

Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.

Botanza.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, sports venues, workshops, warehouses, advertising, etc.

The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.

I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure
