Pay attention to the suitability of choosing ppe

The main problems solved by this debugging:

Increase the upper limit setting frequency of the induced draft fan to allow our company to set the upper limit frequency, but it must not exceed 55HZ.

Replace the differential pressure transmitter that meets the actual testing requirements.

With the external programmers of our company, the communication between the PLC program and the computer was carried out.

Check the spray drying oil level to guide our staff to maintain the dehumidifier.

I personally and the workshop staff know more about the centrifugal towers of your company. We are not qualified enough for preschools in this industry. There are still some blind spots in the maintenance of operating equipment. I beg your company to arrange experienced professional commissioning personnel for our technology. Principles of personnel and operation staff, operation and maintenance of equipment (including but not limited to equipment startup and shutdown, equipment cleaning, equipment monitoring and adjustment techniques, water film dust removal tower cleaning monitoring, dehumidifier maintenance and replacement of efficient filtration, replacement of lubricants and other maintenance Possible emergency response) Of course, some of the maintenance details can be given to our maintenance personnel by dialing.

In the early signing of the contract, we requested to provide relevant key parameters in addition to electronic detection components, but also the need for mechanical instrumentation on-site monitoring display, so that timely detection of measurement and measurement instrument failure. For example, the temperature increases the bimetal thermometer in the field, which has been proposed in the technical agreement.

Windows doors require good sealing performance, and the micro-positive pressure does not leak powder. It is recommended to use the pressure tower window door. It is best to arrange for personnel to replace the first phase of the tower window door.

Spray Dryer Fan Cooling Water Inlet and Outlet Aperture Thread No. is not matched with our company's silk head. If it is convenient, please contact us to supply water for welding.

The interior of the dehumidifier is seriously corroded by the galvanized sheet. The internal temperature probe cannot detect the temperature and there is no humidity monitoring data. Please contact the dehumidifier manufacturer for maintenance.

Gravity Casting Parts

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.

2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.

3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

• Good dimensional accuracy

• Smoother cast surface finish than sand casting

• Improved mechanical properties compared to sand casting

• Thinner walls can be cast compared to sand casting

• Reverse draft internal pockets and forms can be cast in using preformed sand core inserts

• Steel pins and inserts can be cast in to the part

• Faster production times compared to other processes.

• Once the tolling is proven, the product quality is very repeatable.

• Outsourced Tooling setup غير مجاز مي باشدts can be lower than sand casting.
