Post-maintenance And Common Fault Solutions For Rail-type Elevators
Guide rail lifts generally run faster than other lifting equipment when they are purchased from the factory. However, because the use method of the guide rail elevator is different from other elevator equipment, the running speed of the guide rail elevator becomes slower and slower.
1. The lifting speed of the hydraulic guide rail type elevator has slowed down, and the overflow valve should be adjusted by itself. After the relief valve is adjusted, the lifting speed is not increased, but the guide rail type elevator has a fault and stops working.
2. After the equipment is purchased and used, due to improper use, aging, and dirt, the hydraulic guide rail type elevator is used to slow down the speed. After the speed slows down, first consider the factor of hydraulic oil flow. Factors affecting the flow of hydraulic oil include hydraulic pipelines, hydraulic valves, hydraulic oil pumps, motor speed control devices, etc.
3. The overflow valve is generally placed inside the pump station, with an adjustment valve on one side. Its function is to prevent the pressure of the hydraulic system from being too high and it is set to protect the hydraulic system. It is dangerous to simply set the relief valve. If the pressure in the oil cylinder or oil pipe is too high, serious failures such as blasting may occur. The customer of the guide rail type elevator stopped the fault because he adjusted the overflow valve by himself.
Solution
1. The pressure of the hydraulic system should be checked only when the hydraulic guide rail elevator cannot start with the load. If the lifting force is lower than the normal range, the setting value of the relief valve can be adjusted.
2. The hydraulic oil has deteriorated or has impurities. After the hydraulic oil has been used for a long time, there may be impurities or deterioration in the hydraulic oil. Take a sample for inspection to see if it contains solid particles, discoloration, or odor. Replace the hydraulic oil if necessary.
3. The hydraulic pipeline may be blocked. The hydraulic pipeline is also a very important link, check whether the hydraulic pipeline is smooth. Wenshao Lift reminds everyone to focus on checking whether all hydraulic valves, including one-way stop valves, electromagnetic reversing valves, proportional regulating valves, and overflow valves, are blocked or stuck. If there is a problem, the hydraulic valve should be cleaned or replaced in time.
4. The hydraulic pump is also an important factor affecting the flow of hydraulic oil. Hydraulic pumps that have been used for a long time are also prone to problems. When the speed of the hydraulic lifting platform slows down, you should check whether the oil supply flow of the hydraulic pump is stable. If any problem is found, please contact the manufacturer in time to avoid the expiration of the warranty period.
5. There may be a leakage in the hydraulic system. Check whether there is leakage in the hydraulic system, focusing on checking the hydraulic pipes and joints, oil cylinders, and hydraulic valve connections. If there is hydraulic oil leakage, replace the composite pad or wrap the raw material belt.
Precautions for the use of guide rail elevators in winter:
1. Do a good job of anti-slip work: In rainy and snowy weather, if there is rain and snow accumulating on the platform of the elevator, the lifting platform forklift will be very slippery. At this time, we need to clean the platform in time and sprinkle coal chips to take anti-skid measures. If there is heavy rain and snow, the operation should be stopped immediately to prevent accidents.
2. Selection of steel: If the temperature is too low, it will have a great impact on the welding thermal stress and stress concentration of the welding structure of the mobile elevator. Tough low-temperature steel.
3. Replace the hydraulic oil of the mobile lifting platform in time: We must pay attention to the fact that the hydraulic oil used in winter is different from that used in summer, because different viscosities will make a big difference in the internal operation of the elevator system, so in the weather When it is cold, we should pay attention to the use of N32 hydraulic oil.
4. Pay attention to safe use: the above are the points that should be paid attention to when using the mobile lifting platform when the temperature is low. Although the Cathay lift is very safe to use equipment, if it is used improperly, it will also be dangerous. We Try to avoid such accidents.
5. Moisture-proof work should be done well in rainy seasons. It is strictly forbidden to use elevators outdoors in rainy and snowy weather to prevent electrical appliances from being damp, which may seriously cause electric leakage, and there are a series of potential safety hazards.
