Pattern differences and experimental applications


· Object Adapter Mode - In this mode, the adapter, the adapter accommodates one which I wrapped class. In this case, the adapter calls the object wrapped physical entity.
· Class Adapter pattern - this adapter mode, the adapter implementation classes inherit their own (usually multiple inheritance).
Adapter does not have the data rate conversion.
Experimental application
A laboratory centrifuge normally can be equipped with a plurality of rotor, capacity sizes when the same centrifuge capacity needs with the same type but of varying two rotors, valve block you can consider a large capacity to put a hole in the tube adapter in order to achieve suitable for small-capacity test tube test tube hole, so you only need to add a rotor coupled with high capacity to meet the requirements of a set of adapters, so that both can dispense change when dismantling the rotor complex processes, but also save money because of a adapter's price is far lower a rotor price.

Edit this paragraph
Precautions

1) Move the table or spindle, according to the near or far with the workpiece correctly selected speed, moving too fast to prevent a collision.

2) When programming according to the actual situation to determine the proper processing and processing route, to eliminate the position due to inadequate processing or take the side of the workpiece caused by insufficient strength scrapped

Or early fall off.

3) wire cutting programs and must be confirmed before the amount of compensation is correct.

4) Check the wire tension is adequate. In cutting taper, the tension should be adjusted down to the usual half.

5) Check the electrode wire feeding speed is appropriate.

6) to be processed according to the actual situation of open selection process or adhesion process, under the premise of avoiding interference to shorten the distance between the nozzle and the workpiece. Adhesion plus

Hours of work, the distance between the nozzle and the workpiece generally take 0.05 ~ 0.1mm.

7) Check the jet hydraulic couplings stream selection is reasonable, high pressure jet roughing, finishing with a low pressure jet.

8) from the cutting process stability should observe judge found that adverse timely adjustments.

9) process, should regularly inspect and supervise the cutting conditions and found the problem immediately.

cutter Overview


In the machining process, sheet cutting methods are commonly used in hand-cut, semi-automatic cutting machine and CNC cutting machine. Hand-cut flexible and convenient, but hand-cut

Cut quality is poor, socketless fitting dimension error, material waste and subsequent processing workload, while poor working conditions, low production efficiency. Semi-automatic contour cutting machine cutting machine

, Better quality cutting the workpiece, the cutting tool due to its use, is not suitable for single, small and large quantities of cutting the workpiece. Other types of semi-automatic cutting machine while lowering

Labor intensity, but its function is simple, only for some of the more regular shape cutting parts. CNC cutting manual and semi-automatic cutting mode relatively speaking, to be effective

To improve the efficiency of sheet metal cutting, cutting quality, reduce labor intensity of the operator places. Some small and medium enterprises in our country and even in some valve block large enterprises using hand-cut and

Semi-automatic cutting mode is also relatively common.

China's machinery industry steel usage has reached more than 300 million tons of steel cutting very large; With modern machinery industry, for cutting sheet metal work

For efficiency and product quality requirements also increased. CNC cutting machine which is still very large market potential, market prospects more optimistic.

hydraulic hose emergency repair of several methods


Hydraulic hose emergency repair of several methods
    During the construction process, construction machinery hydraulic system hose rupture, you can take the following emergency repair methods.
Stick reinforcing method
When the hydraulic system pressure at 25-8.0MPa rupture between the rubber hose can take when sticky patch method: Wipe clean around the hose rupture; painted in the hose rupture "anaerobic" glue, "Ring epoxy resin "glue," 801 "glue or" 502 "in one glue (glue a length of approximately 2-3 times the length of the rupture site); canvas with tape or glue strip overlying wound at 4 - 5 layers (each layer should be coated with glue); would draw canvas strip wound tape the ends tightly knotted; wait until solidification 15-20min after use.
Bundled France
Bundled law applies pressure 16MPa rubber hose rupture following emergency repair. The specific method is: the hose rupture coated gum foregoing construction machinery used in one; rupture site with a width of 2-3 times the length of the oil and rubber adhesive wound at 2-3 layers (each layer should be coated with glue ); No. 12 wire will be wrapped with good oil resistance rubber bundled good; let it solidify.
Bone France
As external forces reusable fitting (shrapnel puncture, crush fracture) or system overload causes large rubber hose rupture site or about to break, you can take the bone France: Wipe clean the hose rupture and cut rupture site; would homemade steel "bone" Insert the hose is cut off ("bone" parts as shown in the drawings, the situation is particularly urgent, they used the same outer diameter of the bone with the hose pipe when the "bone"); plates with homemade clamp the hose and the "bone" chuck (special emergency situations, the available alternative homemade No. 8 wire steel clamp); would take a good hose to clean after use.
Transposition
In the hydraulic system, the same oil rubber hose whose specifications the same, but different oil pressure to bear. Ruptured hydraulic hose mostly bear a larger hose. If W4-60 type excavator, ZL series loader boom cylinder on the two specifications of the same tubing is always connected to the boom cylinder large cavity hydraulic tubing to withstand greater. Accordingly, the method can be used to take transposition: A simple hose rupture sticky patch or bundled; big will the boom cylinder chamber and small chamber tubing can be used interchangeably (ie with unruptured tubing withstand high pressure, with the But after a simple supplement damaged or bundled tubing sticking to withstand low pressure).
Restructuring Act
As the hydraulic system of the rubber hose fittings vary, while high pressure or high pressure hose rupture should not be used "stick and fill method", "bundle Act" or "bone Law", which can be taken to reform law: Saw fitting the hose rupture; find a burst pressure capability, and the length of the hose the hose replacement approximate and saws its fittings; the fracture angle hose fittings welded to the replacement hose; the welding good hose cleaned immediately after use.
Opening Act
In the hydraulic system, valve block some of the oil plays a protective role in system security. Such as: W4-60 type excavator, ZL series loader steering system from the main oil passage through the relief valve to the tank; TY120 bulldozer working device in the hydraulic system relief valve, overload valves, relief valves, etc. oil. When these oil hose rupture in the circuit method can be taken; abandoned in the circuit protection device (such as a "safety valve", etc.); blocked oil hose leading to rupture, so that the oil circuit. In taking break law, should the system load control at rated load between 85% -95%.


on the hydraulic hose expounded the necessity of corporate culture


 Given the fierce competition of hydraulic hose industry, our company decided to start construction of enterprise culture is significant, I believe that through the establishment of corporate culture can enhance employee cohesion, sense of belonging, it can bring a sense of ownership, I will plant flagship product hydraulic hose to even more broad development platform.
        Set forth below under the necessity of:
        Oriented: able to overall corporate culture and corporate values ​​and behavior of members socketless fitting from the guiding role orientation.
        Constraint: enterprise culture thinking of the staff, and psychological and behavioral norms binding effect.
        Cohesion: the corporate culture cohesion function means that when one set of values ​​shared by employees approved, it will become a bonding force, from all of its members to gather together, resulting in a tremendous solidarity and cohesion.
        Incentive: Corporate valve block culture has a member of the enterprise from the heart to produce a high emotional and spiritual effects to forge ahead.
        Radiation: corporate culture, once formed relatively fixed pattern, it will not only play a role within the enterprise, have an impact on the employees, but also through various channels (publicity, communication, etc.) impact on society.
