Zao QiangHydraReplace with new oil and do not intermittently use old oil, otherwise the moving parts in the system will accelerate wear.
The guide rail type cargo elevator has been inspected and debugged before leaving the factory, and all technical indicators have met the design requirements. When in use, only the power supply needs to be connected, and the hydraulic and electrical systems do not need to be adjusted.
Zao Qiang.Unscrew the screws on the dustproof hole on the outer side of the elevator flange, adjust the PCS system ring to align its side hole with the dustproof hole, and tighten the inner hexagon. Afterwards, remove the motor shaft key.
It is strictly prohibited to connect the motor of the lifting platform to the wrong power supply. It should be ensured that the voltage is 380V or 220V, and daily cleaning work should be carried out. Dust and debris on the motor should be cleaned in a timely manner.
.The power unit adjustment, whether it is a scissor type lifting platform or a guide rail type lifting cargo elevator, is composed of the power unit and the oil cylinder. The power unit has four outlets during production, which can be adjusted to increase or decrease the hydraulic oil flow rate of the oil cylinder. We can adjust the motor speed or the electro-hydraulic proportional valve to adjust the hydraulic oil flow rate; What factors will affect the lifting speed of hydraulic elevators? The longer the hydraulic oil pipe, the longer the lifting time. Therefore, during installation, the length of the oil pipe should be minimized as much as possible within the allowable range of the design; On the basis of adjusting the power unit, 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.
The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder, the faster the lifting speed.
Pay attention to checking each steel wire rope for broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance and upkeep of steel wire ropes should strictly follow the 85 regulations.
After entering winter, elevators are prone to some small problems and malfunctions, which requires users to perform seasonal maintenance and upkeep on the elevator. Below, the editor will briefly introduce the winter maintenance precautions and key points of the elevator.
How do elevator manufacturers maintain and maintain construction elevators? In order to accurately implement the equipment maintenance system, it is necessary to establish a mechanical management responsibility system; It is necessary to develop maintenance procedures for different models; Corresponding maintenance institutions must be implemented; It is necessary to handle the relationship between maintenance and production, so as not to affect production or equipment maintenance.
Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens,Zao QiangLogistics hydraulic lifting platform, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part tighten the pipe joint.
Production department.After entering winter, elevators are prone to some small problems and malfunctions, which requires users to perform seasonal maintenance and upkeep on the elevator. Below, the editor will briefly introduce the winter maintenance precautions and key points of the elevator.
How to install and use the bearings of the elevator? During the process of using the bearing device of the elevator, we cannot always ensure that the bearing device has the right orientation, which inevitably leads to some devices not being in place or bearing displacement. Once these problems occur in the device, it will cause the clearance between the bearings to become too small, and then make it impossible for the inner and outer rings of the bearings to be in the same rotation center. So it is necessary to use specialized tools when installing bearings, and in the future, it is also necessary to use a testing instrument to test the bearing installation, in order to ensure the success of the bearing installation.
What are the maintenance rules for the mechanical equipment of hydraulic elevators? The brakes of each mechanism should be regularly inspected and adjusted to ensure flexibility and reliability. On the friction surface, there should be no dirt present,Zao QiangHydraulic guide rail type lifting platform, and any dirt must be washed off with gasoline or thinner.
In the construction elevator, the switch box also has leakage protection equipment, and its wires and cables have good insulation without leakage. The metal passing through the wires is not rusted, and its damage is close to zero. His steel wire rope should comply with the corresponding configuration requirements without any issues of strand breakage or shrinkage, and of course, the number of broken wires should not exceed the corresponding standards. His pulley movement is very flexible.
Where is good.What are the installation precautions for elevators? The folding fence and cage of the elevator should be cleaned of the foundation surface, and the foundation bolts should be installed properly. If the construction elevator is installed on the floor, a pad iron must be used below the screws to increase the force surface between the nuts and the floor to reduce the impact of the nuts on the floor; Insert steel plate shims of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite to ensure the verticality of each main pipe in both directions. After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and tighten the remaining anchor bolts; Install the buffer spring; Connect the other half of the fence to the front half with bolts; Adjust the verticality and tighten the anchor bolts as above, first install the suspension cage before installing the drive plate).
The hydraulic pipeline is probably congested. The hydraulic pipeline is also a particularly important key, including one-way stop valves,Zao QiangHydraulic small lifting platform, electromagnetic directional valves, proportional control valves, overflow valves etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner, as the hydraulic oil may deteriorate or contain impurities. After the hydraulic oil is permanently used, there may be impurities or deterioration in the hydraulic oil. Take a sample for inspection to see if it contains fluid particles, discoloration, or odor. If necessary replace the hydraulic oil.
There are foreign objects inside the oil delivery pipe of the hydraulic lifting platform, which can cause uneven force distribution during the delivery of hydraulic oil, resulting in uneven surface conditions. It is recommended to carefully check whether the delivery pipe is smooth.
Zao Qiang.In our daily life, the maintenance of hydraulic cargo elevators should not be careless. Below, the editor will introduce the daily maintenance of hydraulic cargo elevators.
Pay attention to checking each steel wire rope for broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance and upkeep of steel wire ropes should strictly follow the 85 regulations.
Regular refueling is necessary for maintenance of the elevator: During the use of the elevator, due to the large load, especially the elevator chain and elevator shaft pins. It is necessary to ensure that an appropriate amount of oil is added before each use to ensure flexibility and non jamming during operation. If the elevator is in operation and once&quo; appears; Squeak and Squeak&# quo; The friction sound can be basically determined to be due to a lack of oil in the elevator. It is necessary to immediately stop working and investigate the cause, and cannot forcibly operate, which can easily cause unforeseeable hidden dangers. Summary: Regular refueling is not allowed when maintaining the elevator.
