Q: How does hydraulic platform change sealing ring, how to operate: Flange join type, should remove flange join screw first, use the screw to remove the end of the cover, can not lever or hammer, lest damage; Inside the card key type connection, should use a special tool, the guide sleeve toward the push, reveal the card key and hydraulic plunger pump used to () after remove the card key items with nylon or rubber texture the card key fill out again after its; Thread connection type oil cylinder, should screw the screw down first; In the demolition of the piston rod and the piston, not hard to pull out of the cylinder, piston rod components should try to keep the components of the piston rod and cylinder axis slowly pulled in a line.

Q: How to automatically lift up and lift: If I want to reach a certain time, the platform automatically drops, how to achieve? There is a time relay. Thank you very much!

Q: How does the platform maintain: Inspect hydraulic oil and oil level. The hydraulic oil should be 40 to 50 mm above the tank when the platform rises to the highest. When the oil is dark, the oil is sticky, or the oil has grit and other foreign things, the hydraulic oil should be replaced in time. The hydraulic system of lift platform applies 32 # hydraulic oil. A. check the hydraulic and pipe joints. The pipe is damaged and should be replaced immediately. Tighten the joint when the connection is loose.

Q: The structure of the universal elevator milling machine: The bed is used for fixing and supporting milling machine parts. There is a horizontal guide to the top of the beam. The front wall is a vertical guide with tails, which can be moved up and down the platform. Internal main motor, main shaft variable speed, main shaft, electrical equipment and lubricating oil pump, etc. The beam end of the beam is equipped with a hanger to support the pole to reduce the bending and vibration of the pole. The beam can be moved along the horizontal guide of the bed, and its stretching length is adjusted by the length of the pole.

Q: Can the stepping motor drive the hydraulic platform?: The hydraulic platform is driven by an oil cylinder, and the motor drive is a completely different way through mechanical means (screw, chain, gear, rack, etc.). In addition to mechanical means, depending on the power size, the step motor usually means that the equivalent power is not much, the maximum is a few hundred watts. The hydraulic platform is generally heavy, so it's unlikely. Or do you use a step motor to drive the hydraulic pump? It can, but also to consider the power problem, said earlier, smaller power stepping motor, if the original motor is a few kilowatts, certainly not.

Q: Do you have a personal elevator with hydraulic platform: Hydraulic platform itself is not flat layer device, the upper and lower limit is oil cylinder and the mechanical structure limits. Platform only "motor" "stop" "up" "down" button. The safety of the sheared platform can also be shaken when it starts and stops, without the thought preparation. In different floor installed several travel switch, electric cabinet, become automatic stop, hardware does not need how many money, the line a little trouble. Can do it. Just installed is not good

Q: How to use the elevator to be safer and more efficient: Constantly check the operation of the various agencies is normal, have no noise, if find fault, the elevator must be eliminated in time. 2, check the connection of the ministries, such as loose should be tight. When the compression of the connecting bolts should be in body check firmness, slightly shaft must have a split pin all connections, and to open fully. Always check all electrical wires and cables for damage. Make sure to cover and replace damaged parts in time. When the motor is overheat, stop the engine in time, and then keep running after the failure. The motor bearing lubrication is good.

Q: There are different kinds of milling machine and vertical lifting machine milling machine: Start by figuring out the difference between vertical and horizontal The main shaft of vertical milling machine is perpendicular to the workbench, and the spindle of horizontal milling machine is parallel to the workbench. The knife of vertical milling machine is relatively flexible, the scope is wider. Can use vertical milling cutter, machine clip, bit etc. Milling keyway, milling plane, boring hole, etc.

Q: Simple manual lifting mechanism, a nut a bolt can: The next face is worn, welding a circle, ok turn, rise, also can not be fixed, also can rise! The general problem is not too big, it's a two-point position, if it's fixed at three points, it's high in accuracy

Q: What is the main shaft of the horizontal milling machine: The main shaft variable speed has the impulsion device, facilitates the speed change, the machine tool can brake quickly and effectively. 4, machine tool of important transmission parts are made of alloy steel, easy to wear and tear of the parts are made of wear-resisting material, guide model, and the service life of the machine to have enough.
