Guide rail typeElevatorMaintenance Skills

In recent years, the guide railElevatorThe equipment is well received by customers. Production orders are increasing. As more and more consumers choose, the problem of guide rail elevator equipment has also appeared. So how to improve the service life of the guide rail lift equipment?

The hydraulic system of the guide rail elevator is the main factor affecting the instability of the gate valve components, resulting in unstable liquid circulation. The direct result is that the supercharger is abnormal, which shortens the normal service life of the guide rail.

The main medium of the elevator is hydraulic oil, which is easy to expand and contract. After startup, the system medium is heated in the cold state. When the weather is cold or hot, the door will open. According to the guide rail typeElevatorIf the system takes some measures, it will inevitably increase the abnormal pressure of the guide rail lift.

The normal opening and closing of the pilot valve is the key to industrial process control. The limit pressure of the valve housing hydraulic lift, the pressure of the valve cover, etc., when the pressure is very dangerous, when the medium is high-temperature gas, toxic and harmful gas, it is easy to be corroded and the pollution is more serious. They are easy and may even cause damage to mechanical equipment and personnel., Buried the seeds of safety hazards and failures. Therefore, part of the overpressure should be checked in time.

The valve design strength of the guide rail valve housing, valve cover, and valve stem of the elevator, the strength of the abnormal pressure nominal pressure and the opening pressure will double, which will cause the use of related components to increase exponentially. When the actual stress exceeds the allowable stress, fracture damage will occur in the high stress area, causing the valve to fail to open, and the valve and machine will be damaged or destroyed.

The main frame support structure of the guide rail elevator requires high-strength steel pipes, which can withstand high loads and ensure that the weight of the platform and goods can be fully supported during work. Otherwise, there are many security risks in the work. The elevator hydraulic system uses hydraulic oil, and anti-wear hydraulic oil is selected as much as possible to reduce the heat generated by friction under working conditions.

The quality requirement of the guide rail elevator must have good anti-skid performance. This is because the cargo or vehicle may fall from the platform onto the cargo when the sliding friction is reduced in view of the safety of the platform. The utility model adopts polyurethane wheels, which improves the stability of the equipment, does not need to worry about tire pressure, and ensures the safety and stability of high-altitude operations.

In order to makeElevatorWhen the hydraulic system or pipeline is suddenly damaged due to accidents, it can work normally without affecting the work progress. The system adopts a hydraulic safety system. At the same time, when the equipment is forced to stop due to sudden power failure or electrical failure, the emergency descent system is adopted in this case to make the personnel and equipment stranded at high altitude return to the ground safely through simple operation.

In order to prevent the hydraulic system from stopping due to the rupture of the rubber hose, a safety valve is used here. During normal operation, hydraulic oil flows from the oil port to the safety valve 3 and enters the second safety valve 1 through the hydraulic rubber hose. The oil in the hydraulic cylinder moves the piston. When one of the hydraulic hoses breaks due to the load of the load cell or other factors, the back pressure of valves 2 and 4 suddenly drops to zero, and the spool valve closes the passage at the broken oil pipe. The oil circuit can still work normally and play a protective role.
