随着人类文明的发展,人们可以建造出各种各样的建筑物,比如:轮船、铁路工程、海上工程、飞机等。于是工程的概念就产生了,并且它逐渐发展为一门独立的学科和技艺。
A project execution is usually divided into some elementary phases, such as :engineering, procurement and transportation, field construction, procom missioning.
We are building an polypropylene plant with an annual capacity of 400,000 metric tons.
The contract number of this project is EPC-LS-ORYANSAB-010-IK.
The Buyer (customer, client)is China National Technical Import Corporation.
Sinopec contracts for domestic and overseas chemical projects.
We can contract to build turn-key plant, undertake single items of projects as a subcontractor or provide labor services.
The Dow takes part in this project as a patent licenser.
Are you the Seller’s Representative on the job site?
I am the Buyer’s General Representative.
It is an inquiry (commercial and technical proposal, approval, agreement ,protocol, annex, technical appendix) about this project.
There are many information in the technical proposal, which including: process flow, process , capacity of the plant, performance of the product.
There are two units (installations) in the contract plant.
The project team normally consists of project engineer, design engineer ,schedule engineer, and various specialists.
We can evaluate the results of field construction by four criteria, which are quality ,time, cost and safety.
I am responsible for the technical (scheduling, inspection, quality control) work of this project.
Would you tell us the technical characteristic about this project?
Please give a about this project.
The project is certain to be a success.
Do you have any reference materials about this project?
We should work according to the overall schedule chart(the construction time schedule)of the project.
The effective date of this contract will begin from July Twentieth , two, dual zero, five.
The Seller will provide preliminary (final )technical documents for Buyer in May.
The basic (detailed) process design will be issued before August.
Our major planning items contain estimating of cost and construction schedule.
We shall have a design collecting (preliminary design, final design) meeting next month.
On our most projects Critical Path Method(CPM) is used for scheduling.
Field erection work (civil work) will begin in June this year and complete on the end of December next year.
This contract plant will start-up (put in commissioning )on January first 2008 .
The date of acceptance of this plant will be December 31,2007.
The plant is scheduled to be completed around 2008.
The Seller’s operating group (A crew of specialists) will remain on the job until guarantees are met.
We must take the plant through the test run and finally into commercial operation.
Every month we shall establish construction schedule.
We shall also make the project schedule report every day .
We are going to begin this work tomorrow.
We must take this work plan into consideration.
We have to change our plan for lack of materials .
What is your suggestion about this schedule?
Give me your opinion on this plan.
This is similar to the preceding feature but applies to tool length and diameter.
In older-style controls, the cutter dimensions had to be set very precisely in order to agree with the tool path defined in the part program.
Other methods for ensuring accurate tool path definition have been incorporated into newer CNC controls. One method involves manually entering the actual tool dimensions into the MCU.
These actual dimensions may differ from those originally programmed.
Compensations are then automatically made in the computed tool path.
Another more recent innovation is to use a tool length sensor built into the machine. In this method, the cutter is mounted in the spindle and brought into contact with the sensor to measure its length.
This measured value is then used to correct the programmed tool path.
Many modern CNC machines possess an no-line diagnostics capability which monitors certain aspects of the machine tool and MCU operation to detect malfunctions or signs of impending malfunctions.
When a malfunction is detected, or measurements indicate that a breakdown is about to occur, a message is displayed on the controller’s CRT monitor. Depending on the seriousness of the malfunction, the system can be stopped or maintenance can be scheduled for a nonproduction shift.
Another use of the diagnostics capability is to help the repair crew determine the reason for a break down of the machine tool.
One of the biggest problems when a machine failure occurs is often in diagnosing the reason for the breakdown.
By monitoring and analyzing its own operation, the system can determine and communicate the reason for the failure.
With the trend toward interfacing and networking in plants today, most modern CNC controllers are equipped with a standard communication interface to allow the particular machine tool to be linked to other computers and computer-driven devices.
We shall put the machine to trial (test run) after the erection work has been finished.
The mechanical completion check list of the unit has been approved by both of the Buyer’s and Seler’s representative.
We should start the installation according to the instruction and operation manual.
The systematic hydrostatic test (dry run , hot test, dynamic test, actual start-up ) is scheduled for next Monday.
We have planned to finish the adjustment of the machine before Tuesday.
Before initial start-up of the installation, we must check the equipment carefully.
Shall we begin the test run at once?
The compressor is loaded up with the medium of air (nitrogen, process gas).
The turbine had been running for 4 hours before carrying a full load.
We shall soon put the chemical installation into commissioning test run.
According to the schedule, the first batch process will be produced on October first this year.
The machine is in good working order.
The machine is out of order, will you see to it , please.
I felt the machine shake seriously.
The machine parts went hot.
