peaceSmall electric elevatorMaintenance analysis

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 downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.

peace.The isolation and buffering rubber in various parts of the aluminum alloy electric elevator drive device are intact and tightly fitted.

Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.

.Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.

The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.

Mechanical devices controlled by cage movement should not be used to open or close the landing door.

The counterweight guide rail should meet the specification requirements.

Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professional

Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position

How many?.Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.

To ensure safe and reliable braking of the lifting platform and prevent accidents, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease,peaceElectric bed elevator, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.

The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.

The setting of the cable guide frame should comply with the user manual and regulatory requirements.

Professional is king.Later,peaceElectric pull rod elevator, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.

The suspension cage movement can only be resumed after operator operation.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements otherwise protective measures shall be taken.

peace.Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.

Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.

Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
