MingshanDoubleThe 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, filter the oil, 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: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
Mingshan.The safety belt should be inspected before use and a static load test should be conducted regularly (every 6 months). The load for the boarding bridge test is 225 kilograms, and the test time is 5 minutes. After the test, check for deformation, cracks, etc., and keep test records. Unqualified seat belts should be promptly dealt with.
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 characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
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.
Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Therefore, maintaining the hydraulic cylinder is an important part of the entire hydraulic system maintenance. In addition, 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
After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally due to overload, insufficient power supply,MingshanLarge hydraulic lifting platform, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.
plan.Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.
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, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, 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, 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.
Voltage too low: Measure the starter voltage,MingshanHydraulic lifting platform, with an allowable fluctuation range of± 10%.
Price.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, 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.
In case of strong wind of level 6 or above, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance,MingshanPlatform hydraulic lifting, cleaning and replace the cleaning hydraulic oil to clean.
Mingshan.Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, check whether the lowering valve is powered on. If there is no electricity, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.
Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops, warehouses and other places; It can also be used as temporary high-altitude lighting, etc.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, 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.
