Q:What happens when the platform comes up and the power goes out.

In pump station oil outlet on the right side with a nut, the nut off, is within the six-party of the screw, counterclockwise, the platform can fall, fall after what must tighten screw clockwise, the back nut, so that next time can normal use

Q:How does a button in the PLC control the elevating platform

The recommended answer is wrong, and the platform should stop at any location. You can either push the button or click the number of times to tell whether it's up or down. For example, press the ascent in one second, press two, and press the button to stop. Instructions will use timers, counters, and pulse detection. You get the idea.

Q:What certificate is required to operate hydraulic platform

I don't know that hua nanjun helped me to do other people's production. You can call and ask for advice. I don't know. Check it online...

Q:On the principle of hydraulic lifting platform, using the foot switch control, when stepping on hydraulic pump, hydraulic platform, depressed when, what is under the control of the hydraulic cylinder pressure?

There is a very commonly used in oil overflow valve, its role is: regardless of the flow of oil, only to a certain pressure to open (internal spring, spring elastic adjustable), also have the effect of pressure.

Q:What should the chain's main elevator be aware of when installing the chain

Oil cylinders and power unit system problems. Too much power or too little can cause all kinds of problems in the elevator, so choose the right power unit.

Q:How to maintain the platform?

Remove the hydraulic oil and remove the oil strainer, remove the oil strainer, clean it up, and then put it back in the tank and connect the pipe. (put on new oil and don't use the old oil. Otherwise, the moving parts of the hydraulic lift system will accelerate the wear and tear.) Remove and disconnect the lift valve, blow the plunger down with compressed air, then load and resettle. Check all hydraulic pipes and connectors. The pipe should not be broken, the joints should not be loose, and all the joints must be tightened.

Q:How to improve the oil leakage line

The reason of oil leakage is complicated, mainly due to the quality of the hydraulic components, vibration, corrosion, differential pressure, pipeline connection, use of improper maintenance. Elevator oil leak inside leakage and leakage. A small amount of oil is inevitable, because of the nature of the hydraulic drive. Spill in excess of the prescribed index of the phenomenon is due to leakage, generally can immediately perceptible, mainly are now the pressure drops, rapid speed of change has been ground or surface of product oil, machine equipment need often fill oil to return to the height of the aerial work platform before. Once the leak is due to be shut down, the acute operation will only take the system out and damage the engine parts.

Q:Operation and attention of electric elevating platform car?

Non-professional personnel shall not adjust the overflow valve, the hydraulic system of each component is within the prescribed work under pressure, adjust the overflow valve, may lead to abnormal operation of hydraulic system. There are unnecessary injuries to people, machines and objects; Before any part of the hydraulic system, the pressure oil should be discharged before the pressure oil gusts out. E, the corresponding moving parts shall add some lubricating oil to extend the life of the bearing. F, check the oil and oil position of hydraulic oil. The platform rises all the way. In this position, the hydraulic oil should be 40-50mm above the bottom of the box. If the hydraulic press is dark, sticky or gravel, it is found that 120 # hydraulic oil should be replaced in time.

Q:Is the music console working? Want to start a, afraid to buy expensive again.

The music and song platform is a one-stop alternate office product, which means you can stand for a while.

Q:Put a large beaker of water on a horizontal platform and put a light glass upside down in the water

The inside of the large beaker is raised, the pressure on the surface of the large beaker is larger, and C is right. The pressure of the bracket on the glass is downward, the pressure of the gas is rising, the glass gravity is constant, the pressure of the bracket is greater for the glass, and the D is wrong
