Borewell Compressors

Agriculture Borewell Compressor Pumps

Borewell up to 700 Feet

Product Descriptions

“NEC” Compressor Pumps designed the Domestic and Industrial purpose with High Operating Efficiency and work at the depth of 1200 feet at single Phase , Depth of 2000 Feet at Three Phase , Compressor coupled high quality motors to ensure the efficient performance. It works on the principle of difference in density of two-inter-connected water columns and the heavier one over balancing the lighter one operation. Compressed air is pumped down in to the well and gets mixed with water in to the delivery pipe as very fine air bubbles by the air – distributor installed at the end of the air pipe line. This air – water mixture having a low density than the surrounding water column rises in the discharge pipe. On continuation of this process, water is pumped through the discharge pipe. These Pumps are robust in construction and tested at high standard excellence.

NEC The borewell compressors pump works on the principle of difference in density of two-inter-connected water columns and the heavier one over balancing the lighter one. Water outflow through delivery pipe will be pulsated. the discharge of water will greatly depend on the yield of the bore. Air distributor fitted at the end makes this operation possible.

Air Compressor Cylinder

Cylinders of the reciprocating compressor are used in the process industries are separable from the frame. They are attached to the frame by way of an intermediate part known as the distance piece. The cylinder will accommodate the both suction and discharge valve plates.

Normally most of the cylinders used in the process are equipped with replaceable liners. The purpose of the liner is to provide a renewable surface to the wearing portion of the cylinder. This saves the cost of replacing a complete cylinder once the bore has been worn or scored. In the larger, more complex compressors, this feature is standard or readily available as an option. On the smaller frames, particularly the single-stage models, the smaller cylinder size is such that the replaceable liner is not economical and may not be available.

The cylinders are equipped for cooling to reduce the temperature during the compression cycle. This is usually by means of a water jacket. If water jacketing in the cylinder is not feasible than fins are provided in the cylinder for air cooling.

For hydrocarbon service, steel is most desirable, although not universally available.

For capacity control, clearance pocket included in the cylinders.

Compressor Cylinder Head

All industrial reciprocating compressors are equipped with Crosshead. The crosshead is used to guide the piston in the cylinder bore. The following are the advantage of crosshead

• The compressor can use a narrow piston, due to the use of narrow piston larger valve area for greater efficiency.
• Permits a longer stroke and greater capacity.
• Separates crankcase from the cylinder, allowing control of oil carryover into the cylinder.
• Gives greater stability to piston, eliminating piston “slap” and reducing ring wear

Bearing

The main and connecting rod bearings should be split-sleeve, steel-backed, babbitted insert type.

The cross head pin should have a replaceable bush bearing

Connecting Assembly

For the reciprocating compressor of above 150 kW(200 hp), have forged steel connecting rod are used and for compressor less than or equal to 150kW machines ductile iron material is used. Like Crankshafts, the connecting rod should have drilled hole for oil passage. The connection rod used to connect the crankshaft and the crosshead. The connecting rod converts the rotary motion into reciprocating motion. The connecting rod bolts and nuts shall be securely locked with cotter pins or wire after assembly.

For reciprocating compressor of above 150 kW(200 hp), have forged steel connecting rod are used and for compressor less than or equal to 150kW machines ductile iron material is used. Like Crankshafts, the connecting rod should have drilled hole for oil passage. The connecting rod converts the rotary motion into reciprocating motion. The connecting rod bolts and nuts shall be securely locked with cotter pins or wire after assembly.

Piston

The piston is the heart of the reciprocating compressor. The piston translates the energy from the crankcase to the gas in the cylinder. In order avoid the leakage of compressed the piston and cylinder, the piston is equipped with a set of sliding seals called as piston rings. Usually, the rings are made of a material, that having self-lubricating property to reduce the slide friction force between the cylinder and the piston. This to avoid the wear in the cylinder wall and also increase efficiency by reducing the friction force.

Different types of rings are used for lubricated or non-lubricated service. In the case of non-lubricated service, the rings shall have good self-lubricated property. Usually, this type of piston ring made up of PEEK and other fluorocarbon compounds.

For lubricated service, metallic rings such as cast iron or bronze as well as non-metallic materials such as filled nylon are used. Nowadays the compressor manufacturer preferred non-metallic materials because of less weight when compare with metallic rings.

Normally the piston is made up of lesser weight materials such as aluminium and aluminium alloys, this is to reduce the reciprocating compressor shaking forces and Rod load. In the case, piston diameter larger piston diameter hollow pistons are also used to reduce the weight.

Rings

The tangent ring cut into three segments so that each cut lies on the side of an equilateral triangle. The cuts of this ring maintain sealing contact regardless of variations of the ring’s inside diameter. As wear occurs, the ring segments will close radially to compensate while still maintaining sealing contact at the tangential joints by mean of Garter Spring .

CrankShaft

Larger compressors, normally above 150 kW(200 hp), have forged steel crankshafts. for compressor less than or equal to 150kW machines ductile iron crankshaft. Crankshafts should have removable balance weights to compensate for rotary unbalance as well as reciprocating unbalance.

Force lubrication is used, the crankshaft oil passages should be drilled. The Figure shows a drilled crankshaft. In the case of machines above 150kW,
