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.
The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain， driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years， with the advantages of higher lifting height， stable operation， and simple maintenance compared to the scissor fork type elevator.
UptarThis product has a solid structure， high load-bearing capacity， smooth lifting， easy installation and maintenance， and is an ideal cargo transportation equipment for replacing elevators on lower floors.
Voltage too low: Measure the starter voltage， with an allowable fluctuation range of± %.
Southern cecumReason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted， and if the adjustment is ineffective， replace it with a new valve.
The use of cleaning oil and the brand used in the system
When encountering signs of overheating in the electric motor， it is necessary to park the car in a timely manner， clean the problem， and continue running. The motor bearings should be smooth and outstanding.
The installation personnel should confirm and count the equipment details， confirm that there are no omissions in the shipped equipment details， check if the tools are complete， 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， whether it is a scissor type lifting platform or a track type lifting platform thus achieving the adjustment of lifting speed. The power unit adjustment is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes，Uptar12 meter hydraulic lifting platform， 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.
Each box， distribution box， etc. should be kept clean and promptly cleaned of dust on electrical equipment.
Fair priceLifting 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，UptarScissor fork hydraulic lifting platform， and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems， and there should be no leakage at all components， pipelines， and joints.
The development of elevators is at its peak， as many manufacturers have chosen more multi-story buildings to fully utilize the site， so they also need a device to facilitate the improvement of goods.

When the hydraulic oil of the equipment is insufficient， it will not cause lifting. At this point， you only need to add enough hydraulic oil to run.
Superior qualityTherefore， the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply， using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit， the oil is supplied by the pressure limiting variable pump， and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
The hydraulic pump also has an impact on the flow rate of hydraulic oil. If the hydraulic pump is used for a long time， it is also prone to problems. When the speed of the hydraulic lifting table slows down， it is necessary to check whether the oil supply of the hydraulic pump is firm and firm.
The hydraulic lifting platform is a manually movable type， and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power，UptarGuide rail hydraulic lifting platform， and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement， stable lifting， and easy operation， and are mainly used in factories， government agencies， commercial stores， and the construction and decoration industry.
UptarMotor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
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， hotels， logistics， warehouses， supermarkets， 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， 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.
The hydraulic pump produces noise. When the hydraulic elevator rises， which causes periodic changes in the hydraulic system pressure， it will also cause resonance in the hydraulic system and generate noise.
