When disassembling and adjusting the reverse organization of the equipment, attention should be paid to ensuring that the centerline of the reverse organization reducer is parallel to the centerline of the gear, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers,Nai meihengHydraulic lifting platform, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.
Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
.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, and attached electric construction platforms.
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal have uniform color, no bubbles, no cracks, pits, paint leakage, and sagging.
The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, and sleeve type lifting platforms according to their different modes of movement.
Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.
Carefully prepare a special construction plan for installation and construction and provide safety technical disclosure to installation personnel.
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.
Sampling inspection.The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
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.
Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.
Quality inspection report.. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,Nai meihengProfessional hydraulic lifting platform, 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. In order to ensure a smooth descent of heavy objects and safe and reliable braking, 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.
Usage and instructions for steel wire ropes in elevators: The steel wire ropes of the steel wire ropes require very high strength, usually made of high-quality carbon steel with a carbon content of 0.5% -0.8%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity, light weight, smooth operation, no noise, suitable for high-speed transmission, high strength, strong overload capacity, and reliable operation, it has become a commonly used rope for hydraulic elevators.
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,Nai meihengHydraulic guide rail type lifting platform, 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.
Nai meiheng.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
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.
When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
