New OrleansHyd. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, 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.
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, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
New Orleans.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?
The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end,New OrleansFixed hydraulic lifting platform, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
.The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
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.
After 1500 hours of elevator operation perform minor repairs to the mechanical and electrical systems.
Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
Many operating factories often require the use of hydraulic cargo elevators, which can be lifted and lowered, making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, thus achieving the adjustment of lifting speed. The power unit adjustment, whether it is a scissor type lifting platform or a track type lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder, Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
Information recommendation.When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner,New OrleansFixed electric hydraulic lifting platform, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
When using hydraulic elevators, hydraulic system failures, 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.
Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
The characteristics of the platform include reliable hydraulic system, simple operation, and rear hinge support.
Test method.After the pre installation is completed, the pre installed equipment should be fixed and the positions of cables, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.
For example,New Orleans12 meter hydraulic lifting platform, setting anti fall and interaction can achieve good usage effects. This product is mainly used in various enterprise factories.
The use of cleaning oil and the brand used in the system
New Orleans.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
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.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
