Anyone with a little mechanical knowledge knows that energy can be transformed into each other. It is best to apply this knowledge to the tank hydraulic jacking system to explain the power loss of the hydraulic system. Next, we will introduce in detail how to maintain the tank hydraulic jacking system.
Here is the content list:
l Maintain the tank hydraulic jacking system from the perspective of power source.
l Maintain the tank hydraulic jacking system from a pressure perspective.
l Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Maintain the tank hydraulic jacking system from the perspective of power source.
On the one hand, the power of tank hydraulic jacking system will cause energy loss and reduce the overall efficiency of the system. On the other hand, this part of the energy lost will be converted into heat energy, which will increase the temperature of the hydraulic oil and the deterioration of the oil. The tank hydraulic jacking system is malfunctioning. Therefore, when designing a tank hydraulic jacking system, under the premise of meeting the requirements of use, full consideration should be given to reducing the power loss of the system.
First of all, considering the power source-pump, considering the diversified working conditions of tank hydraulic jacking system actuators, sometimes the system requires large flow and low pressure; sometimes it requires small flow and high pressure.
Therefore, it is appropriate to choose a pressure-limiting variable pump, because the flow rate of this type of pump changes with the change of the system pressure. When the tank hydraulic jacking system pressure decreases, the flow rate is relatively large, which can satisfy the fast stroke of the actuator. When the tank hydraulic jacking system pressure increases, the flow rate decreases accordingly, which can meet the working stroke of the actuator. This can not only meet the working requirements of the actuator, but also make the power consumption more reasonable.
Maintain the tank hydraulic jacking system from a pressure perspective.
Second, when hydraulic oil flows through various types of hydraulic valves, there will inevitably be pressure loss and flow loss. This part of the energy loss occupies a large proportion of the total energy loss.
Therefore, reasonable selection of hydraulics and adjustment of pressure valve pressure are also an important aspect of reducing power loss. The flow valve is selected according to the flow adjustment range in the tank hydraulic jacking system and its minimum stable flow can meet the requirements of use. The pressure of the pressure valve should be as low as possible when the hydraulic equipment is working normally.
Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Third, if the actuator has speed regulation requirements, when selecting a speed regulation loop, it is necessary to meet the speed regulation requirements while minimizing power loss. The speed control circuits of common tank hydraulic jacking system mainly include: throttle speed control circuit, volume speed control circuit, volume throttle speed control circuit.
The throttling speed control loop in the tank hydraulic jacking system has large power loss and good low-speed stability. The volumetric speed control circuit has neither overflow loss nor throttling loss, which has high efficiency but poor low-speed stability. If the tank hydraulic jacking system needs to meet both requirements at the same time, a volume throttling speed control circuit composed of a differential pressure variable pump and a throttle valve can be used, and the pressure difference between the two ends of the throttle valve should be as small as possible to reduce pressure loss.
In summary, a reasonable choice of hydraulic pressure is crucial. When the hydraulic oil flows in the pipeline, it will exhibit viscosity, and when the viscosity is too high, it will generate greater internal friction, causing the oil to heat up, and at the same time increase the resistance when the oil flows. When the viscosity is too low, it is easy to cause leakage, which will reduce the volumetric efficiency of the tank hydraulic jacking system.
Therefore, generally choose oil with suitable viscosity and good viscosity-temperature characteristics. In addition, when the oil flows in the pipeline, there are pressure loss and local pressure loss along the way. Therefore, when designing the tank hydraulic jacking system pipeline, the pipeline should be shortened as much as possible while reducing the number of bends.
The above are the recommended maintenance points to avoid the power loss of the oil tank hydraulic jacking system. However, there are many factors that affect the power loss of the tank hydraulic jacking system. Therefore, if specific maintenance is performed on the storage tank hydraulic jacking system, other requirements should be considered comprehensively!

What are the economic benefits of using an orbital welding machine?
The orbital welding machine uses the heat energy generated by the combustion of the oxygen-acetylene flame to heat the ends of the butt-welded rails to a molten state, and then applies a certain upsetting pressure to weld the rail ends. There are two existing methods: factory welding and mobile welding. Factory welding is the same as contact welding. The mobile welding method, also known as small air pressure welding, is mainly used to weld the joint joints of the long rails on the construction site. The quality of air pressure welding is also better. Aluminothermic welding. Put the prepared aluminothermic flux (made of metal aluminum, iron oxide, iron alloy and iron nail head, etc.) into a special crucible, ignite the flux with a high-temperature match, and produce a strong chemical reduction reaction to obtain high-temperature molten steel and molten steel. Slag, after the reaction is calm, inject it into the preheated sand mold tightly fastened to the ends of the two rails, melt both ends of the butt joints, remove the sand mold after cooling, and reshape the welded joint in time. Welded into one. The quality of aluminothermic welding is poor, and the fatigue strength is even worse, only reaching 45% to 70% of the base metal.

Hydraulic storage tank lifting equipment plays a very important role in handling heavy objects. The lifting effect is very good. It is more suitable for lifting heavy objects with a low height and can undertake a lot of lifting operations.
What are the precautions for hydraulic storage tank lifting equipment?
What should I do if the platform of the hydraulic storage tank lifting equipment lift cannot be lowered?
What is the working process of hydraulic storage tank lifting equipment?
1) If the emptying phenomenon occurs during use, you can first loosen the oil drain screw on the pump body, hit the vertical head of the pump body down a few times, and then tighten the oil drain screw, you can continue to use the hydraulic storage tank lifting equipment.
2) When using, do not add partial load or overload, so as to avoid the danger of hydraulic storage tank lifting equipment damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
When using hydraulic storage tank lifting equipment lift, sometimes the lifting platform cannot be lowered. The solution to the hydraulic storage tank lifting equipment lift not being lowered depends on the situation:
1. The drop valve fails,
Troubleshooting method: In the case of pressing the down button, check whether the down valve has electricity. If there is no electricity, try to eliminate it; if there is electricity, then eliminate the failure of the down valve itself and replace the drop valve.
2. The deceleration control valve is out of balance
Remedy: Adjust the descending speed control valve, if the adjustment is invalid, you need to replace the new valve.
When the hydraulic storage tank lifting equipment is stretched, the front and rear oil nozzles are opened, and oil is supplied from the rear oil nozzle to the tensioning working oil chamber, and the cylinder body of the tensioning cylinder moves backward. Since the cylinder cable is anchored on the tool anchor at the top of the jack, the hydraulic storage tank lifting equipment stretches the steel cable through the tool. When the wire rope is stretched to the required length, close the rear oil nipple, and feed oil from the front oil nipple into the top pressure cylinder, so that the top pressure cylinder piston moves forward to support the anchor plug, and the anchor plug is pressed into the anchor ring. Thus, anchoring the cable. Open the rear oil nozzle and continue to feed oil from the front oil nozzle. At this time, the tension cylinder moves forward and the oil in the cylinder returns. Finally, open the front oil nozzle to make the oil in the top pressure cylinder return, and the top pressure piston returns to its original position due to the action of the return spring.
