How to perform a sprinkler stall test The sprinkler automatic transmission stall test test is used to measure the maximum engine speed when the shift lever is in the D or R position and the torque converter is out of order. This test measures the working conditions of the torque converter, guide wheel unidirectional detacher, and the fixed performance of the clutch and brake in the transmission. The test method is as follows: Check the transmission oil level, temperature, and engine coolant temperature. When testing, make sure that no one is in front of or behind the vehicle. Oil level: At the "HOT" mark of the dipstick. Oil temperature: 80~100°C. Retreat to neutral, but not reverse gear, to prevent the transmission from the 5th gear directly to reverse people. Sprinkle truck to reverse gear After the shift lever first returns to the neutral position between 3rd and 4th gear, the internal shift lever will move backward first, then move to the 5th gear/reverse shift position, and the internal gear will change. The relative positions of the lever and reverse gear and the position pin become. At this time, rotate the internal shift lever in the direction indicated by arrow D to replace the reverse gear without any interference from the reverse limit pin. Prevents mistakenly changing the working diagram of the reverse gear mechanism. What are the causes of gear wear? Gears of manual transmissions often work under conditions of high rotational speed, high load, speed and load, and normal sprinkler wear is not avoided. In addition to normal wear, gears will also cause gear impacts due to poor lubrication, poor lubrication conditions, improper driving operation, improper meshing of gear assembly during maintenance, etc. Gear teeth will not mesh properly and start-up jitter will accelerate gears. Wear and damage. In addition, the wear of other parts of the gear or other parts (such as spline grooves in gear holes, bearings, spline shaft bending, etc.), improper assembly of the clutch or drive shaft, manufacturing defects (such as non-uniform carburized layers, gears Warp, etc.) will also accelerate gear wear.
We started to manufacture Lighting Pole from 2001 and exported from 2003. We got CE certificate for Lighting pole from 2015.
Our firm introduced whole set of good-sized numerical control hydraulic
folding equipment(1280/16000) as well as equipped with a series of
good-sized professional equipments of armor plate-flatted machine,
lengthways cut machine, numerical control cut machine, auto-closed up
machine, auto-arc-weld machine, hydraulic redressing straight machine,
etc. The firm produces all sorts of conical, pyramidal, cylindrical
steel poles with production range of dia 50mm-2250mm, thickness
1mm-25mm, once taking shape 16000mm long, and large-scale steel
components. The firm also is equipped with a multicolor-spayed
pipelining. At the meantime, for better service to the clients, our firm
founded a branch com. The Yixing Jinlei Lighting Installation Com,
which offers clients a succession of service from design to manufacture
and fixing.
