Q:Hydraulic platform repair work instruction book, trouble which big man helps to provide
Jinan zhihua elevator machinery co., LTD. Is specialized in the production and development of a unit hydraulic elevator for the oil and oil. The lift is raised all the way up. In this position, the hydraulic pressure should be 40 to 50 mm above the bottom of the box. Hydraulic oil is a variation of dark, sticky or grit, such as a discovery should be replaced in time (32 # hydraulic oil) The lift is maintained every year Check all hydraulic pipes and connectors. The pipe shall not be broken, the joints shall not be loose, and all the joints must be tightened.
Q:The hydraulic platform is compared with the normal lift platform
Light weight, good maneuverability, suitable for one-man operation. The special mast strap-roller device, which is stable and stable.
Q:What happened to the rise and fall
The motor is missing (the motor is not moving, and there is a buzzing sound) to check the circuit breaker and the electrical wiring. The drop valve is open when the drop button is released, and the voltage meter is used to check if the valve has electricity. If there is no electricity, check the line and troubleshoot it. If there is electricity, the valve itself is out of fault. The slide valve must be clean and flexible. The overflow valve is adjusted to the relief valve. Under 100% rated load to adjust the oil level is too low, the oil pump hydraulic oil filled up at a empty absorption, oil absorption filter clogging, clean filter, oil leakage, check the suction tubing and connectors; Tighten the joint.
Q:Do you have a personal elevator with hydraulic platform
In homes that jump a layer or double entry house how to select the elevator, first of all let us clear the elevator and the elevator is introduced here, live in has crush that jump a layer or double entry house of friends, if you want to know more, can
Q:Seven tons of lift should be fitted with the straight screw and motor
Can be judged according to the accuracy requirement of lead screw grinding or rolling, depending on the load and its acceleration can choose servo power right away and screw the maximum load capacity (do longer engineers can intuitive judgment the diameter of the screw and large), so that you can around the power of the servo motor of the different speed and different lead screw to match, so there will be several different schemes: high speed servo motor with small lead screw (sometimes deceleration machine), big inertia servo with lead screw. Under the condition of the machine cost to determine, from two to three scheme choice, choice of method is to choose low cost, with high stability, cost effectiveness and cost are the same common and suppliers have a spot. If the single from choose the ways of the servo and screw usually have an intuition, like 3000 revolutions of servo goods on the market the most sufficient, screw is according to the supplier's inventory.
Q:The automatic mahjong machine has a lift station always one. What is the other three normal
There are two main reasons for this: In the ascent of the aluminum plate, the interference with the limit mechanism
Q:How to improve the oil leakage line
Hydraulic cylinder oil leak, should be hydraulic cylinder seal damaged, want to replace seal, also check hydraulic cylinder piston Wear and burrs, piston wear and burrs are easily damaged by sealing, causing oil leakage. If you have That requires a new hydraulic cylinder or professional maintenance.
Q:What happens when the platform comes up and the power goes out.
The electromagnetic valve core can be artificially pushed back.I hope my answer will help you
Q:There is no elevator on the 7th floor of the home to install a lift or lift
All manned lift, lifting platform, moreover, to pass through security, common theory suitable equipment can't be through security inspection, after you installed the safety bureau will let you immediately removed. These things are too low
Q:There are different kinds of milling machine and vertical lifting machine milling machine
Vertical nc milling machine is the most widely used in nc milling machine. The bench mill expands the use range and is generally more accurate than vertical. The processing technique is for the workpiece, the process of the same workpiece is the same. Welcome to adopt
