Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.

The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment which has been favored by many users.

Matt Sarka.Ensure a good power supply at the installation site, install a separate distribution box, and when using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the leakage switch should be compatible with the frequency converter when selecting it.

When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear,Matt SarkaChanging manual hydraulic lifting to electric hydraulic lifting, the larger the shaking range,Matt SarkaFixed electric hydraulic lifting platform, especially for mobile hydraulic cargo elevators. When the working height exceeds 10 meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.

The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, stable operation, and simple maintenance compared to the scissor fork type elevator.

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.

Separate: Loading and unloading on different platforms.

Hydraulic oil is the blood of the cargo elevator. Maintaining the cleanliness of hydraulic oil is an important factor in extending the hydraulic freight elevator. How to maintain the cleanliness of hydraulic elevators?

Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.

discount.The hydraulic pump produces noise. When the hydraulic elevator rises the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.

Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.

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, the oil seal or straightening rod must be replaced in a timely manner.

Load bearing capacity: The lifting platform is placed on a horizontal support surface, each load-bearing component must not have deformation or cracks.

Quotation sheet.Therefore, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.

Personnel engaged in high-altitude operations must be healthy, and those who suffer from mental illness, epilepsy, or have been identified by a doctor as having hypertension, heart disease, or other diseases that are not suitable for high-altitude operations are not allowed to participate in high-altitude operations. When it is found that staff members are drinking alcohol or feeling low spirits, it is prohibited to work at heights.

When using hydraulic elevators frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, but also enables it to exert greater power during operation. Of course hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).

Matt Sarka.The manufacturer of hydraulic cargo elevators reminds the use of guide rail hydraulic lifting cargo elevators. Guide rail hydraulic lifting cargo elevators: Do not stand within the specified range, draw on the guide rail lifting platform,Matt SarkaFixed hydraulic elevator, prohibit any idle personnel from entering the work area, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.

Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.

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, separation of air contained in oil and elimination of foam.
