There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable the starting voltage drop is too large and the price of the cargo elevator is reduced.Zwaller,The overflow valve cannot be debugged on its own. The reason why hydraulic cargo elevators are slow is mainly due to human factors in the later stage. Therefore, attention should be paid to maintenance and upkeep during use to reduce accidentsLines of various safety equipmentMukacheve,The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, 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.This paper briefly introduces some matters needing attention in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic system of elevators and hydraulic elevators and other hydraulic machinery are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.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.

Wholesale manufacturers of hydraulic cargo elevators have found that the market demand for hydraulic cargo elevators is also increasing. More importantly, some cargo loading and unloading work, as well as decoration, hotels, logistics, warehouses, supermarkets, etc., are commonly used in these situations, especially in the decoration industry. I have seen many decoration companies use small hydraulic cargo elevators, which are also specially processed and manufactured, and have some differences from the hydraulic cargo elevators we often see. There are significant differences in structure, shape, lifting speed and height, and the prices of hydraulic cargo elevators also vary. The hydraulic cargo elevators used in the decoration industry have a low lifting height,ZwallerSelf hydraulic lifting platform, some only meters, and do not require many materials. He mainly promotes people,Zwallerfork lifter, not goods, so the load is small, but not inferior to the use of other hydraulic cargo elevators. He is stable, safe, interpretable, and durable enough to make hydraulic cargo elevators a good helper in the decoration industry. The function of hydraulic cargo elevators is gradually improving with our needs and the properties we require are different. Wholesale manufacturers of hydraulic cargo elevators also manufacture according to our requirements.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.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).management,Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.Do you know the classification of simple cargo elevator lifting platforms?

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.Good quality,The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits,ZwallerHydraulic lifting table lifting, and speed switching circuits.When working simultaneously at the upper and lower levels, a tight and firm protective partition, and workers must wear safety helmets.Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.Zwaller,Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.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.
