The above are the working principles of three common elevators, and there are also some forms of elevators that are not common,Zao QiangCustomized hydraulic lifting platform, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
Zao Qiang.Advantages of geotechnical engineering: There is no need for a computer room above the shaft, and the top floor height can reach over 5 meters.
Selection of the location of the loading and unloading lifting platform In order to reduce the cost of material handling, the location of the platform should be selected to minimize the distance of the handling tools and vehicles in the factory. It is much easier to move a fully loaded transport vehicle to a designated location outside the building than to transport the loaded materials one by one to the designated location indoors. When selecting a platform location, full consideration should be given to the production process and operational needs of the factory. There are two modes of platform layout: merging: loading and unloading on the same platform.
.Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.
There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, and the pipelines should avoid dead bends as much as possible.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
The manufacturer of hydraulic cargo elevators tells you the precautions to be taken when installing hydraulic cargo elevators. Hydraulic cargo elevators work using hydraulic systems and are usually used for the transportation of large goods. Hydraulic cargo elevators are different from traditional shelf elevators. They use a new hydraulic system to reduce the occurrence of faults and utilize their own weight to reduce energy consumption when lowering goods. So, what should be paid attention to when installing hydraulic cargo elevators? The hydraulic cargo elevator manufacturer is here to tell you!
Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements, and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.
reform.For hydraulic cylinders in hydraulic elevators,Zao QiangAluminum alloy hydraulic lifting platform, 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.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). 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. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
Quality risk.What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting and high safety.
Safety advantages: Hydraulic elevators are equipped with the safety devices of traditional traction elevators: overflow valve: it can prevent system pressure from being too high when going up; Emergency manual valve: In case of power failure, it can cause the car to emergency descend to the nearest floor position, causing the car to emergency descend to the nearest floor position, and causing the emergency in the car to descend to the nearest floor position; Pipeline rupture valve: When the hydraulic system's pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descending; Oil temperature protection of oil tanks: When the oil temperature of the oil tank exceeds the standard setting value, the oil temperature protection device sends a signal to stop the use of the elevator and wait for the oil temperature to decrease before starting the elevator. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!
Wholesale manufacturers of hydraulic cargo elevators have found that the market demand for hydraulic cargo elevators is also increasing. More importantly, some cargo loading and unloading work, as well as decoration, hotels, logistics, warehouses, supermarkets, etc., are commonly used in these situations,Zao QiangSmall hydraulic lifting and leveling, especially in the decoration industry. I have seen many decoration companies use small hydraulic cargo elevators, which are also specially processed and manufactured, and have some differences from the hydraulic cargo elevators we often see. There are significant differences in structure, lifting speed, and height, and the prices of hydraulic cargo elevators also vary. The hydraulic cargo elevators used in the decoration industry have a low lifting height, some only 2 meters, and do not require many materials. He mainly promotes people, not goods, and rarely promotes goods, so the load is small, but not inferior to the use of other hydraulic cargo elevators. He is stable, safe, interpretable, and durable enough to make hydraulic cargo elevators a good helper in the decoration industry. The function of hydraulic cargo elevators is gradually improving with our needs, and the properties we require are different. Wholesale manufacturers of hydraulic cargo elevators also manufacture according to our requirements.
Zao Qiang.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, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.
There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing repeatedly adjust the pressure, exhaust and clean the valve body several times, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
