BrugesStraight top hydraulic lifting platformHow do company employees improve their abilities

For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.

Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, check whether the lowering valve is powered on. If there is no electricity, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.

Bruges.Oil pipe leaks oil. Poor sealing of oil pipes, oil leakage, resulting in a decrease in pressure and a natural descent of hydraulic cargo elevators. It is recommended to carefully check whether the oil pipes are intact and undamaged.

Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.

.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.

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

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

When placing materials on the platform, they should be placed in the middle of the platform as much as possible. The weight of the goods should be within the standard load range of the equipment, and the volume of the goods should not exceed the platform size of the equipment. Otherwise,BrugesMobile hydraulic lifting platform/lifting platform, materials and lifting platforms may be injured and dangerous accidents may occur. High priced and various specifications of elevator manufacturers provide timely supply with high cost-effectiveness, and have become the preferred brand for many wire products. Welcome to purchase!

It is not allowed to throw tools and materials up and down, and ropes should be used to tie or hang them to avoid injuring workers or scaffolding below.

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

Respect for customers.When encountering signs of overheating in the electric motor,BrugesGuide rail hydraulic lifting platform, 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.

Voltage too low: Measure the starter voltage,BrugesSmall hydraulic lifting and leveling, with an allowable fluctuation range of± 10%.

To consider its capacity, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.

The electromagnetic coil of the electromagnetic directional valve is not firmly fixed and frequent separation and suction can also produce high noise.

Click to view.This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, for situations with large lifting loads and small lifting heights, a lifting mechanism should be selected. For situations with small loads but large lifting heights, a lifting mechanism should be selected. According to the initial structure of the jacking, in order to meet the stability requirements, the size and lifting type of the oil cylinder are increased, and in order to achieve the same effective area as the jacking force, the oil cylinder is added. If the latter is larger, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more major repairs will be carried out to the mechanical and electrical systems.

Bruges.The hydraulic oil used in the system has the same brand, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.

The use of cleaning oil and the brand used in the system

Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.
