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 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 air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, 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.

Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.

Zamoshik.Based on experience, new steel wire ropes will not suddenly break when used under normal circumstances, unless incorrect operation or safety protection devices fail, as the load borne by the steel wire may exceed its breaking capacity. The damage to the steel wire rope of the cargo elevator is mainly gradually formed during long-term use. After a certain period of repeated bending and friction, the steel wire on the surface of the steel wire rope will experience bending fatigue and wear, and the steel wire on the surface layer will gradually break. At this point, if it cannot be used again, it should be replaced in a timely manner to ensure the safety of the hydraulic platform.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

. 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, low or high hydraulic oil viscosity,ZamoshikHydraulic fixed lifting platform, 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,ZamoshikElectric hydraulic fixed lifting platform, 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.

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, perform minor repairs to the mechanical and electrical systems.

The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.

Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, priority should be given to the hydraulic oil flow angle.

Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.

Promotion.Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.

When the hydraulic oil is insufficient, the hydraulic pump will experience suction causing air to enter the hydraulic oil and producing high noise.

There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.

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 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.

Superior quality.Remember not to overload, overload is the root cause of many faults.

Below, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, low or high hydraulic oil viscosity and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.

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 resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing,ZamoshikHydraulic self lifting platform, 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.

Zamoshik.Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.

A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.

The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far
