KefeldDouble fand the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve
. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional 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.
Therefore, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Kefeld.A lifting platform is a lifting device that lifts people or goods to a certain height. When vertical conveying is carried out in logistics systems such as factories and automatic warehouses, various flat conveying equipment is often installed on the lifting platform as a connecting device for conveying lines at different heights. Usually driven by hydraulic pressure, it is called a hydraulic lifting platform. In addition to being used for transporting goods at different heights, it is widely used for high-altitude installation maintenance, and other operations.
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.
. 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, Make the damping hole unobstructed 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.
Materials enter the production line at one end of the factory building, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
The load of goods and the tonnage of goods transported at once also affect the lifting speed. The optimal value for transporting goods on a lifting platform is speed. If it is too heavy, it will affect the speed.
The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.
plan.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.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators to avoid any worries about after-sales service.
Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.

Quality assurance.Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, but it may slowly rise during use. When the equipment is working, it mainly uses hydraulic motors to drive hydraulic pumps. So what is the reason for the slow movement? Professional elevator manufacturer with large quantity and excellent quality at a reasonable price. Fire resistant, waterproof,KefeldFixed electric hydraulic lifting platform,KefeldStraight top hydraulic lifting platform, sturdy and durable, safe and reliable
Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
Kefeld.The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
