Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.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, the oil seal or straightening rod must be replaced in a timely manner.Rilystad,When the hydraulic cargo elevator needs to work, first connect the power supply and press the button to drive the motor of the hydraulic power unit to drive the gear pump. The hydraulic oil forms a certain pressure through the vane pump and passes through the oil filter; Explosion proof electromagnetic directional valve; Throttle valve; Hydraulic control one-way valve; The balance valve enters the lower end of the hydraulic cylinder, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, explosion-proof electromagnetic directional valve.Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.Nanjing,When using hydraulic elevators, 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 above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, 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.After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.

Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.Hydraulic cargo elevators are mainly used for the transportation of high-altitude goods such as factory assembly lines, cargo warehouses parking lots, docks, buildings, logistics, etc. This product can achieve multi-point,RilystadHousehold elevator, interactive interlocking between upper and lower floors, achieving safe use and carrying capacity of tons. The above are the fields in which hydraulic cargo elevators are applied and the characteristics of hydraulic cargo elevators that we want to share with everyone.Lines of various safety equipmentProduct range,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, 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, shape, 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 meters, and do not require many materials. He mainly promotes people not goods, and rarely promotes goods, 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.The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.To consider its capacity generally mobile equipment takes - times the high flow rate of pump Z, and fixed equipment takes - times.

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, cleaning, and replace the cleaning hydraulic oil to clean.Price, 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, if possible, please use safety protection measuresIt is not allowed to throw tools and materials up and down,RilystadDouble fork hydraulic lifting platform, and ropes should be used to tie or hang them to avoid injuring workers or scaffolding below.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.Rilystad,The undercut length of the weld mm should not exceed % of the weld seam, and the depth should not exceed .mm.. 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,RilystadDouble shear hydraulic lifting platform, 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.Remember not to overload
