Description
Pressure test and grease injection dual-use gun ALKZZ-70 is for: flange, high pressure valve injection of high pressure sealing grease and small capacity high pressure product pressure test detection. Application of oil field, chemical pipeline, pressure vessel and maintenance base of all kinds of valve grease and pressure test
Method of use
1. Select the connecting head nut of the grease injection gun head (two kinds of nuts 1M20 × 1.521 "- 14 teeth in front of the grease injection barrel) if the connection thread on the valve or pipe is M20 × 1.5, place the M20 × 1.5 nut in the front head,and vice versa, the nut with 1"-14 teeth.
2. Unscrew the screw cover at the front end of the grease injection barrel (note: the front end of the cap is equipped with connectors M20 × 1.5 and 1 "- 14 nuts).
3. Put the sealing grease or butter that needs to be injected into the grease injection gun barrel and compaction it.
4. Tighten the rotating cover of the grease injection barrel.
5. Tighten the grease injection gun head in front of the grease injection barrel to the connection port on the valve or pipe.
6. Connect the fast joint at the back end of the grease injection barrel with the fast master joint in front of the tubing of the ultra-high pressure manual pump.
7. Tighten the unloading handwheel and handle on the manual pump until the seal grease or butter is injected.
8. Repeat the above actions if you need to do so many times.
9. If the length of the grease injection tubing is not enough, one of the tubing equipped in the box can be used (rotating the grease injection gun head in front of the grease injection barrel, spinning into the internal thread at one end of the tubing, and the other end of the tubing into the position of the original grease injection gun head in the barrel, and ensuring that the rotation is tight without leakage).
