**Product Specifications** - **Model No.:** 2HM - **Flow Rate:** High Output - **Suction:** Double Absorption - **Trademark:** HUANGGONG - **Transport Package:** Wooden Case - **Specification:** 2HM280, 560, 800, 1400, 2500, 4200, 7000, 18000 - **Origin:** China - **HS Code:** 8413 --- **Product Description** Our twin-screw pumps are designed for a wide range of industrial applications. They are ideal for use as fuel oil pumps, diesel oil pumps, heavy oil transfer pumps, lubricating oil pumps, and chemical pumps. These pumps can handle various non-solid containing fluids or extremely high viscosity media with high reliability, even in corrosive environments or gas-liquid mixtures. **Technical Parameters:** - **Capacity:** 0.5–1500 m³/h - **Pressure:** 0.1–2.0 MPa - **Viscosity:** 0.5–100,000 mm²/s - **Temperature:** -30°C to 200°C - **Medium:** Various types of lubricating oils, fuels, and other viscous liquids **Construction Options:** - Horizontal, vertical, portable structures - Heating chambers available for different operating conditions **Safety Features:** - Explosion-proof design - Water protection - Safety valve - Alarm sensors **Application Fields:** 1. **Petrochemical Industry:** Transfer of lubricants, crude oil, residual oil, heavy oil, bitumen, diesel, and gasoline. 2. **Shipbuilding Industry:** Fuel oil, lubricating oil, waste oil, bilge sludge, and seawater transfer. 3. **Chemical Industry:** Acid, alkali, salt solutions, resins, glycerin, olefins, polymers, and cosmetics emulsions. 4. **Paint Industry:** Printing ink, paint, oil-based paints, and dyes. 5. **Food Industry:** Alcohol, beverages, honey, sugar juice, toothpaste, milk, soy sauce, animal and vegetable oils, and chocolate. 6. **Oil Storage & Transportation:** Loading and unloading oil at stations, ships, and tankers. **Key Features:** 1. The inlet and outlet design ensures sufficient fluid remains in the pump, maintaining excellent self-suction performance even when the suction pipe is fully drained. 2. The special circular valve in the pump body opens when the outlet pressure exceeds the working pressure, allowing some medium to return to the inlet, reducing startup torque. 3. Synchronizer gears transmit torque between the screws, preventing metal contact and ensuring reliable operation under any conditions. 4. The meshing screws create sealed cavities that move axially during rotation, delivering liquid smoothly without pulsation. 5. Multiple heating structure options are available to suit different temperatures and media requirements. **Customization Options:** - Horizontal, vertical, or trolley structures - Explosion-proof levels, IP ratings, and insulation for hazardous areas - Special stainless steel for food-grade or corrosive applications - Heating chambers, safety valves, and alarm sensors **Performance Data for 2HM Series Twin-Screw Pumps** | Parameter | Value | |------------------|------------------------------| | Capacity | Max: 2500 m³/h | | Pressure/Head | Max: 25 bar | | Viscosity | 0.5–100,000 cst | | Speed | 750–1500 rpm | | Temperature | -20°C to 120°C | | Mounting | Vertical/Horizontal | | Seal | Mechanical Seal | --- We offer comprehensive technical data, performance specifications, and application guidance for our twin-screw pumps.

CNC Milling

The CNC milling process is a digital manufacturing process that is implemented by computer numerically controlled (CNC) machines. This process is used to produce parts with complex shapes, and the manufacturing process involves multiple steps. The following are the detailed steps of the general CNC milling process:Design: First, you need to design a CAD model of the parts you want to produce. A CAD model is a three-dimensional image created using computer-aided design software that can describe the shape, size, and features of a part.Programming: Next, you need to convert the CAD model into G-code, which is a type of computer instruction that controls the movement and operation of the CNC machine. G Code can be written manually or generated automatically using CAM software.Prepare the machine: Before you start machining, you need to check and prepare the CNC machine. This includes checking the machine's coordinate system, setting tools and cutters, and setting parameters such as the machine's speed and feed speed.Processing: After the machine is ready, the processing can begin. The machining process usually consists of multiple steps, such as roughing, finishing and drilling. At each step, the CNC machine moves tools and workpieces according to instructions in the G code to achieve the desired cutting operation.Inspection: After processing, the parts need to be inspected to ensure that they meet the design requirements and specifications. Inspection can be carried out by using measuring instruments, templates and other testing tools.Polishing and surface treatment: Parts can be polished and surface treated if needed to improve their surface finish and corrosion resistance. This can be done through the use of abrasives, chemicals and other tools.In short, the CNC milling process is a high-precision, high-efficiency manufacturing process for the production of parts with complex shapes. Through the control of CAD model and G code, the precise control of machine motion can be realized, so as to achieve high-precision parts processing.
