2.Mining machinery:For mining machinery and equipment lubrication, vertical mill circulating lubricating oil pump, ball mill gear lubricating oil pump, coal mill thin oil lubricating pump, cement mill thin oil lubricating pump

3.Hydraulic technology:In forging press, injection molding machine, discharge device, elevator lift, Marine propeller, hydraulic winch and other equipment, as a hydraulic pump to provide power hydraulic services.

Product Advantages

 

1.A3NK screw pump changes the traditional high pressure oil balancing technology, the use of active screw and driven screw axial force low pressure area mechanical balancing device, so that the screw force balance uniform and stable, screw does not deform, stable and reliable operation, low noise no pulsation

2.The screw is the core of the pump. The A3NK screw is made using a special processing technique that enhances the screw’s hardness, tensile strength, smoothness, and precision. During the transportation of media, it effectively establishes an oil film, which is fundamental to ensuring the pump’s operational lifespan.

3.A3NK screw pump is a commonly used three-screw pump in industry, which is very suitable for installation in small Spaces, at the same time, we can also lift For the concave shaft version, it is smaller in size

4.A3NK screw pump, can provide a variety of oil inlet configuration to choose to meet the needs of different working conditions.

SELECTION GUIDE

To provide a more suitable pump, we need to understand as much detailed information as possible. You can request the working condition survey form from me. If you are replacing an existing pump, you can provide me with the original product model or nameplate.

Instructions for use

Before starting for the first time, please fill the lubricating medium oil to ensure that a good oil film is formed on the surface of the screw pair and spiral groove. If you want to make the service life of the screw pump longer, the following points are very important

1.It is strictly forbidden to tighten the import and export connection flange, so that the base pump body deformation and displacement, damage the inherent accuracy of the pump

2.When configuring the pipeline, it is strictly forbidden to damage the coaxial tightness of the pump and the motor to ensure the reliable sealing of the import and export pipeline connection.

3.During installation, the rubber plug of the inlet and outlet must be removed, and any impurities and welding slag must not enter the pump chamber.

4.It is strictly prohibited to operate or use water media without media. Or use other media to clean the pump.

5.Long unused and before the first start, the pump cavity must be filled with the use of media.

6.The pipe diameter configuration must be consistent with the pump diameter. The inlet and outlet pipe valves must be opened when starting.

7.It is strictly prohibited to use pressure exceeding the rated working pressure of the pump.

8.Do not adjust the safety valve adjusting bolts, which have been adjusted before delivery. The safety valve cannot be used as an relief valve

9.It is strictly prohibited to disassemble the pump parts without the written permission of the manufacturer

10.Screw pump is a positive displacement quantitative pump, its working pressure depends on the system load.
