GB/T 25618.2-2010Earth-moving machinery -- Lubrication fittings -- Part 2: Grease-gun nozzles (English PDF)

Foreword

GB/T 25618 "earth-moving machinery lubricants Cup" is divided into two parts.

--- Part 1. nipple type;

--- Part 2. Oil injection nozzle gun.

This section GB/T 25618 Part 2, this part identical with ISO 6392-2:1996 "earthmoving machinery lubricants Cup 2 Part I. oil gun grease nipple "(in English).

This section is equivalent translation ISO 6392-2:1996.

For ease of use, this section made the following editorial changes.

--- "This International Standard" be replaced by "this section";

--- Instead of using the decimal point as a decimal point ",". ",";

--- Remove the foreword to international standards;

--- To ISO 6392-2:1996 international standard referenced with the international standard has been adopted as a standard in place of the corresponding;

--- Increasing the GB/T 9799 in the normative references;

--- The GB/T 7306 moved to the normative references from Reference;

--- To increase the figure caption Figure 1;

--- Figures 2 and 3, delete the symbol phi diameter d ago.

3 Grease nipple type and installation location

4 Structure

Oil Gun Grease nipple should be able to withstand 20MPa pressure of work, and at a minimum breaking pressure 80MPa no leakage.

When the gun is used to track the oil regulator, the grease injection pressure may exceed 50MPa; oil gun during disengagement will reduce residual pressure Note
