1, choose appropriate specifications ring spanner (
Preferable)
Or open end wrench;
Choose the outside micrometer with 0 ~ 25 mm;
2, choose suitable soft lead wire diameter (
0.
5 < d < 1。
3mm)
Paragraph 2, each length of about gear section circumference;
3, the operation of lead wire (
1)
Assembled the main, driven gear;
(
2)
Paste separately with the grease will be three soft lead wire on the Lord, driven gear pitch circle;
(
3)
Install the pump cover (
Including gaskets and shaft sleeve)
2 ~ 3 times, symmetrical evenly tighten nut;
(
4)
Symmetrical evenly screw pump under the cap nut, remove the pump cover, remove the soft lead wire and clean;
(
5)
Select four points in each lead wire, measured with outside micrometer thickness measuring soft lead wire and record;
4, the measurement data analysis (
1)
Calculate the average value of eight measurements, namely as the axial clearance;
(
2)
According to the measured axial clearance value with the normal range (
As a general rule, be 0.
06 ~ 0.
10 mm, low-pressure pump allows to 0.
10 to 0.
25毫米)
Compared to conclude that can continue to use or need to repair.
