Hydraulic pumps help in converting mechanical energy into hydraulic energy. In most cases whenever a hydraulic machine is having some problem, one of the main attributable factors is the pump. And invariably, in majority of the cases, this is the main reason for the woes of the mechanics. As far as hydraulic test pump is concerned, it is usually carried out in the workshops where the mechanic will set things right for the client. And the best part is that you do not have to shell out a huge amount of money in order to carry out the tests.
Prior to the hydraulic pressure test pump is carried out; an experienced mechanic will not blindly dismantle the pump and start testing. He will in fact carry out 3 simple tests, which have been explained below. And in most of the cases, anyone that has been in this line will do the same thing and not dismantle the pump right away. So, let us see what these 3 simple tests are prior to carrying out the hydraulic test pump.
1. Rotating the shaft test - A pipe wrench is taken. With the help of this tool, the shaft is rotated few times. This is usually done to identify torque resistance and if there is excessive vibration or not. If there is excessive vibration, there is something wrong with the bearings and its rotating ability.
2. Pressure line test - This test is also performed prior to hydraulic pressure test pump. This is also known as the air in pressure line test. An air gun is made use of in this test. The other end is sealed with a piece of cloth. Thereafter, you blow air into it. If there is sufficient air coming out, it means something is wrong with the rotary group. However, as far as the amount of air (that is assumed to be normal and the amount that is referred to as excessive) can be best judged by an expert or experienced mechanic. So, if you are new to this field, you should certainly allow your senior to carry out the test.
3. Flashlight test - This is another test that ought to be undertaken if you want to find out what exactly is wrong with the hydraulic pump. With the help of LED flashlight peep inside drain ports enclosed in a casing. If you find small parts like chips, crumbled pieces lying inside due to wear and tear of the internal parts of the pump, you can conclude that the pump is broken.
So, without wasting time and effort on dismantling the pump during the hydraulic test pump, you can instead carry out the 3 tests to safely conclude the damages that have been done.
