How to adjust measures to local conditions to choose the pump ?
The common agricultural water pump type are the centrifugal pump, axial flow pump, mixed-flow pump, well pump, submersible pump, turbine pump and so on.In agricultural production, should according to the requirements of different parts of the production conditions and choose different performance of drainage and irrigation machinery. In plain area, HeWangHua water abundant, wide field, autumn winter drought, summer rain, often encounter the heavy rain, heavy rain, waterlogged farmland, require rapid drainage. These areas due to the low-lying, water head is not high, but the irrigation or drainage carrying capacity is big, should adopt "low head and large flow" performance characteristics of axial flow pump. In the mountains, because the field is narrow, high water head, the flow is not big, appropriate chooses performance characteristic of high head, small flow centrifugal pump. In view of some mountainous steep mountain stream
How to improve the efficiency of agricultural water pump work?
Pump efficiency is a measure of the level of effectiveness of the work of a technical and economic indicators. It refers to the effective power of the pump (i.e., the pump output power) and a pump shaft power (ie, the pump input power) ratio. Pump efficiency is typically 65% to 90%, large pumps up to 90%. Pump efficiency level depends largely on the use of the pump, if improper maintenance and use, even to produce high efficiency pumps, but also reach the purpose of economic operation efficiency and low consumption. Therefore. The actual operation of the pump should endeavor to improve the efficiency of the pump. To minimize the energy to pump the water in the process, there is the loss of the energy. Reduce the volume loss. Volume loss is water flowing through the water after the leakage of traffic, including from the mouth ring clearance, packing seal and pump impeller balancing the loss of water holes and other premises.
Energy saving method of six of the farm diesel engine?
One is to increase agricultural diesel engine cooling water temperature is generally lower than the water temperature 45 ºC, the engine does not burn completely , oil viscosity, increase the running resistance , and thus more fuel , so the need to improve the diesel engine cooling water temperature.
The second is to ensure the best delivery advance angle 195 type diesel engine fuel supply advance angle best angle of 16 " to 20 ." When the diesel engine used for some time , due to the injection pump plunger parts and auto parts wear, fuel supply advance angle is reduced , fuel too late , fuel consumption increases, so should ensure that the fuel supply advance angle in the best angle.
Third, ensure that the machine is not leaking diesel oil pipelines often due to uneven joints , gaskets deformed or damaged there is leakage . The solution is : the gasket coated with paint on the glass polished valve , pipe joint can be corrected . additional diesel recovery . Can be used instead of a hollow screw cap bicycle spokes , or plastic pipe nipple on the return pipe and hollow screw connections , so back to the oil into the tank.
Fourth purification before use diesel fuel failures by more than half fuel system . The solution is : buy diesel shelved 2 to 4 days and then precipitated using 98% of the impurities can be precipitated . If are bought and used , place the filter in the fuel tank or toilet paper to put two layers of silk , which can filter out impurities.
Five is to change the " big horse cart " approach wells on common " big machine with a small pump " phenomenon, is actually a waste of energy approach. Improved approach is: appropriate to increase engine pulley , in the case of diesel increased deceleration running pump speed, flow, head shaft power increase, reaching energy efficiency goals .
Six is to adjust the injector fuel injection pressure of 195 type diesel engine injector fuel injection pressure of 12O +5 Lunar / square cm . When the injection pressure is lower than IO0 kg / sq cm, the increase in fuel consumption IO ~ 20 g / kWh . Direct comparison method checking or adjusting the pressure on the fuel pump .
