Q:There are several reasons for the hydraulic cylinder oil leak on the elevator

Oil cylinder in and out tubing joint cracking; (I've seen a lot of this in practice.) 2) the sealing damage of the piston rod with the piston rod is caused by the pull of the piston cylinder. 3) cooperate with cylinder liner piston rod out end seal is damaged, this is caused by long-term use of seal aging more, also has a lot of end cover on is too hard to seal extrusion is damaged, there is a lot of domestic manufacturer of hydraulic cylinder design is not reasonable cause (mostly in order to save costs)

Q:Can the stepping motor drive the hydraulic platform?

Are you a driver for this motor? But the normal step motor is only for torque, step Angle, phase number, not for rotational speed; It may be a servo motor or torque motor, and if the speed is low it is the possibility of torque motors. In addition, you can measure the current, voltage or waveform below.

Q:Which is good for mobile goods elevators?

Everyone knows that a penny a points goods, jinan economic brands cargo-lifts, although is not the lowest market price, but the interior of the lift platform all electronic components is a product of the military level,

Q:The characteristic of shear fork platform

Shear fork lift platform is mainly used in the logistics industry, production lines, lifting, loading and unloading goods to floor between basement, can also be used to lift stage, lifting work station, etc. The product has a stable structure, low failure rate, reliable operation, safe and efficient and easy to maintain.

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 is the main shaft of the horizontal milling machine

CNC horizontal knee-type milling machine is rigid and can withstand heavy load cutting. The CNC horizontal knee-type milling machine has sufficient power and wide spindle speed range. Can use carbide tool for high-speed cutting and make full use of tool efficiency.

Q:The home is decorated, make a tatami mat the platform should pay attention to what aspect?

The second is to notice whether the product has a secure clamping system. Most of the products on the market are mechanical clamping system, which is low in safety, and the system is too resistant to it. Best choice is the electronic control system, because it will through the electronic system induction to the resistance changes, more than a certain value will stall, electric and automatic recovery (electronic resistance setting values are very sensitive, high security), such as task of children. The third is, of course, the manufacturer and the brand, the good manufacturer and the brand make the product more reliable, which is not to be said in detail.

Q:How do you remove the horizontal universal elevator milling cutter

Tie rod and the threaded part of the milling cutter is too short, removing cutter bar back a loose, threaded connections even fewer number of buttons, easily when tapping threads dozen hair, and make the cutter not screw down, or make the damage of tie rod.

Q:How does the elevator repair

Professional personnel should not uninstall electrical appliances at will, in case of electric shock or mistake. The platform should be hoisted and supported when the platform is being repaired under the platform of the platform, so as to prevent the sudden descent of the platform, causing casualties. The overflow valve should not be adjusted arbitrarily. Every element in the hydraulic system works under pressure. Any adjustment of the overflow valve may cause the hydraulic system to operate improperly. There will be unnecessary damage to people, machines and things. In any part of the hydraulic system, the pressure oil must be unloaded first, lest the pressure oil spout and the table suddenly fall. Monthly maintenance A. Roller, shaft and bearing, oil cylinder pin shaft and bearing, arm hinge shaft and bearing, etc.

Q:What is the reason for the automatic lowering of the hydraulic platform

The non-leakage of pressure oil is the key factor for the non-drop, so check the one-way valve
