LB series gear pump scope of application

The range of application of LB series gear pump is suitable for conveying non-solid particles and fibers, non-corrosive, the temperature is not higher than 80 ℃, the viscosity is 5 ~ 1500ST or similar lubricating oil. LB series gear pump purposes: can be used in the transmission process transmission, booster pump. In the fuel system can be used as delivery, pressurization, injection fuel pump. In all industrial areas, can be used for lubricating oil pump. Structure characteristics of LB series gear pump Gear adopts international advanced technology in the 1980s. A double arc sinusoidal tooth profile. Compared with the involute gear, the most outstanding advantage is that the tooth gallery has no relative sliding in the process of gear mating, so there is no wear on the tooth surface, balanced operation, no liquid trap phenomenon, low noise, long service life and high efficiency. The gear pump to get rid of the shackles of the traditional design, making the gear pump in the design, production has entered a new field. Pump with differential pressure relief valve as overload protection, safety valve full back pressure of the pump rated discharge pressure of 1.5 times. Can also be allowed to discharge pressure within the scope of the actual need to be adjusted. But in the allowable discharge pressure range according to actual needs to be adjusted. However, this valve can not be decompression long-term work, if necessary, can be separately installed in the pipeline. The pump shaft bees are designed in two forms, one is a mechanical seal, the other is a packing seal, according to the specific use and user requirements.

Center drill bits, also known as Slocombe drill bits, are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a workpiece in which to mount a lathe center. In either use, the name seems appropriate, as the bit is either establishing the center of a hole or making a conical hole for a lathe center. Nevertheless, because of the frequent lumping together of both the terminology and the tool use, suppliers may call center drill bits combined-drill-and-countersinks in order to make it unambiguously clear what product is being ordered.

1). Center drill types are commonly used to drill holes which provide small diameters. Mostly used to create pilot holes, they are very useful as they can guide the worker to correctly perform the holes he needs. Once the hole is located in the right place, the center drill has to be replaced with a normal drill which provides the right diameter. However, in order to use the center drill, you have to provide the proper lubricant so that the drill`s tip is not going to be twisted off while performing a specific task.
