JiangsuTwo tonThe 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 220V. 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.
The lifting platform is placed on a horizontal support surface
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, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.
Jiangsu.On the other hand, under the action of high pressure, the hydraulic system inevitably causes the hydraulic valve to flow back or the sealing components to produce oil. The main reasons for the natural descent of the hydraulic cargo elevator include the following points: replacement of the support valve due to leakage. The lowering valve is damaged or not powered on. Require the lowering valve to be kept clean on a daily basis, and if damaged, replace it with a new hydraulic lowering valve in a timely manner.
When the hydraulic system malfunctions,JiangsuElectric hydraulic fixed lifting platform, 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.

The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.
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, which have certain constraints.
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different operation heights, roller, rotary table, steering,JiangsuSmall hydraulic lifting platform, tipping, telescoping), and with various ways (separate, linkage, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
Compare the measurement curves and then go to the variable displacement pump or variable speed motor. Long term targeting all types of high-priced elevator manufacturers nationwide with reasonable prices and comprehensive services, we have gained recognition from our customers
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
Potential development.When the hydraulic oil is insufficient, the hydraulic pump will experience suction causing air to enter the hydraulic oil and producing high noise.
. 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.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
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, pipelines and there should be no leakage at all components, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.
Cleaning and maintenance: When there is oil in the oil tank or when oil is refilled, it is necessary to ensure the cleanliness of the filter tank cover. Clean the oil and funnel or container before use. Never bring dirty things into the system, only clean oil.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Jiangsu.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,JiangsuHydraulic lifting platform 18 meters, 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.
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%.
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.
