DV650Laibao screw pump maintenanceThe following preparations should be made beforehand.

① Master the operation situation and prepare necessary drawings and materials.

② Prepare all maintenance tools, measuring tools, accessories, and materials.

③ Cut off the power supply and the connection between the equipment and the system, cool, blow, and replace the internal medium thoroughly, and meet the safety maintenance conditions.

DV650Laibao screw pump maintenance|Laibao screw oil-free compression vacuum pump is a dry pump designed specifically for industrial applications,Used in industrial fields such as solar photovoltaic industry, large-area coating, industrial furnaces, etc,Used to solve demanding vacuum problems,Such as dust, tar, etc.DVThe series hasDV250toDV1200Multiple different models,The design pumping speed is250～1200m3/h,The ultimate vacuum degree can reach0.01mbar.DVThe series is oil-free vacuum pump,Due to the lack of oil lubrication in the vacuum chamber,Therefore, dust will not remain in the pump chamber,But as the gas is discharged from the exhaust port outside the pump,No need to dispose of waste oil,Very environmentally friendly. Hollow inside the screw,There is a cooling device,The surface of the screw has a very hard coating,The screw has a long service life. The pump chamber casing can be easily disassembled,Easy to clean the screw(When necessary),And it can be completed by the user themselves at the customer's site. compared toSCREWLINEThe design adopts the concept of easy maintenance,And equipped with a fault monitoring system,Ensuring safe operation and reliability.
