Agricultural pump energy saving: cancel the bottom valve, gate valve and check valve

1, at the end of the valve, the valve resistance coefficient at the end of a larger, generally reduce the head of about 1.5 meters. The efficiency of the pump will be significantly improved after the bottom valve is removed. If the mouth in the outlet pipe fitted a pat door, and then sealed the stuffing box with butter, so stop the pump when you start again do not have to fill.

2, cancel the gate valve and check valve, gate valve and check valve resistance coefficient is relatively large, the role of gate valve is to regulate the amount of water, but the pump does not have to regulate the amount of water, it can be omitted. The role of check valve is to prevent the water back, with the door, it does not need a check valve.

3, the pump ramp loading (or turn the pump volute) This allows direct access to the water inlet and outlet pipes to reduce the elbow.

4, to reduce the loss of pipeline filter Use O.8 mm steel wire instead of the filter, so that cross-section porosity increases and reduce power consumption.

5, the inlet pipe to have enough depth of submergence When the depth of submergence is not enough, the water will produce tour vortex, the air into the pump, reducing pump efficiency. Submerged depth of influent pipe should be greater than 0.5 meters.

6, to avoid "anti-aircraft" type water law as the outlet pipe is higher than the surface of the water pool, head loss, nozzle water will produce reflected waves in the sidewalls, increasing the outlet pressure, affecting effluent.

7, the selection of economic pipe diameter resistance loss and pipe diameter inversely proportional to the fifth power, the smaller the pipe diameter, the greater the resistance. The outlet pipe of the economic diameter of the pump flow after the O.65-O.8, the economic pipe diameter of the water flow after the 0.8-0.92 times.

8, timely removal of runner blockage If there is blockage of impurities into the water pipes, impeller or diversion channel, will reduce the amount of water.

9, improve the efficiency of the belt transmission Note that the belt tight side and loose side of the drive package angle, do not use the wide belt to narrow belt, and pay attention to the tightness of the belt.

10, change the ring, adjust the axial gap impeller port ring gap, the volume efficiency decreases. Therefore, to regularly check the mouth ring gap. The value of axial clearance, should be adjusted according to the factory instructions.
