December 30, 2013

To reduce the risk of low temperature corrosion or cracking occuring in the lower portions
of liner, can be done by using load controlled cooling system or insulating the cylinder spaces prone to this risk

Why atomisation test should not be done in slide type fuel valves

December 29, 2013

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
