SilmhantanElev
SilmhantanFixeAluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material, which is lightweight and has a more beautiful appearance. The disadvantage is that it has a light load capacity and is only suitable for simple high-altitude maintenance work, and can only provide support for 1-2 people.
Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, only clean plastic plugs can be used to seal the end of the pipeline.
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage,SilmhantanHydraulic small lifting platform, and sagging.
.The hydraulic lifting platform is a manually movable type, 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 and are mainly used in factories, government agencies, commercial stores, and the construction and decoration industry.
The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, stable operation and simple maintenance compared to the scissor fork type elevator.
Solution: Check if the performance of the legs is good, the overflow valve is stuck or severely worn even if the butter is polished to increase its properties.
The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil,SilmhantanHydraulic lifting platform fixed type, 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.
The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.
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, cleaning, and replace the cleaning hydraulic oil to clean.
Application process.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.
The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
To consider its capacity, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
Quality management.The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
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.
After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work,SilmhantanScissor fork hydraulic lifting table, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, 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.
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, speed regulation can change both the flow rate and the motor displacement.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
