SentesHydrauli
SentesMobile hElectrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
Sentes.The manufacturer of hydraulic cargo elevators tells you the reason for the instability of hydraulic lifting equipment. Hangzhou hydraulic cargo elevator equipment has always had good stability, mainly used for heavy types of goods. However, during use, Hangzhou hydraulic cargo elevators may inevitably encounter some faults during the lifting process such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?
Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than 50%.
.When using hydraulic elevators, 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 lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, 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.
A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, priority should be given to the hydraulic oil flow angle.
The use of cleaning oil and the brand used in the system
plan.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,Sentesfork lifter, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.
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.
Protective device: In case of power or oil circuit failure there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
Statistics.Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times,SentesScissor type hydraulic lifting platform, each load-bearing component must not have deformation or cracks.
Generally speaking, for situations with large lifting loads and small lifting heights, a lifting mechanism should be selected. According to the initial structure of the jacking, in order to meet the stability requirements, the size and lifting type of the oil cylinder are increased, and in order to achieve the same effective area as the jacking force, the oil cylinder is added. If the latter is larger, a lifting mechanism should be selected.
The use of cleaning oil and the brand used in the system
Sentes.Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
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.
When using hydraulic elevators, the main causes of noise are mechanical mechanism failures, hydraulic system failures,SentesGuide rail hydraulic lifting platform, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
