In rural regions, petrol and diesel pump sets remain heavily relied upon for agricultural irrigation, yet farmers frequently encounter various technical glitches with these machines. Rajesh Prasad, operator of Sandeep Machinery located in Chas, Bokaro, has shared essential insights regarding the common problems that occur in petrol and diesel pump sets along with their practical solutions.
What to Do When the Pump Discharges Low Water
According to Rajesh, if a pump set is discharging noticeably less water than before, multiple underlying reasons could be responsible. Typically, a defect in the packing gland causes a reduction in the water flow. In such a scenario, replacing the packing gland can significantly improve the water discharge. Furthermore, a malfunctioning or broken governor spring also diminishes the machine's capacity. Replacing such damaged parts is crucial for restoring proper pump operation.
Addressing Excessive Noise from the Machine
If the pump set produces louder or more abnormal noise than usual while running, the silencer may be at fault. Under these circumstances, the silencer should be thoroughly inspected and replaced if necessary to ensure smooth operation.
Dealing with Black or Blue Smoke from the Engine
Emitting black smoke is a frequent issue encountered with petrol and diesel pump sets. As Rajesh explains, this usually happens due to accumulated dirt inside the air cleaner or an excessive supply of fuel entering the engine. To prevent this, the air cleaner must be cleaned meticulously. Additionally, the injection pump requires professional inspection and repair by a mechanic.
Meanwhile, blue smoke emerging from the engine is often caused by worn-out oil rings or using low-viscosity engine oil. In this situation, faulty oil rings should be replaced, and the machine must always be operated with engine oil of the correct viscosity.
Neglect Leads to Reduced Machine Efficiency
Rajesh points out that farmers sometimes fail to properly maintain their pump sets. Dirt or debris entering the machine can reduce water pressure and impair operational efficiency. Consequently, periodic cleaning and essential inspections of the equipment are vital.
If the pump set engine fails to start at all, potential causes include malfunctions within the fuel system, a malfunctioning fuel pump, a clogged filter, or water entering the fuel line.
In such a scenario, the trapped air inside the fuel line must be bled out first. Additionally, the fuel pump should be checked, choked fuel filters replaced, and old fuel oil changed if required. Paying attention to these measures enables the engine to resume optimal performance.
Key Considerations When Installing a Pump Set
When installing a pump set, a location should always be selected where the suction pipe length is kept to a minimum. Additionally, the height of the suction pipe should remain low so that water can easily reach the machine.
The pump must be positioned in a spot where all essential components, such as joints and bearings, can be easily inspected. Furthermore, the machine should consistently be placed on dry and level ground.
According to expert Rajesh, maintaining peak performance from a pump set also requires timely engine oil replacement. The engine oil should be changed after approximately 150 hours of machine operation. This practice preserves engine efficiency and ensures the equipment functions effectively over the long term.
