Diesel oil pumping unit pump use the correct installation steps and the note

The correct installation and use diesel oil pumping unit, in order to ensure the service life of diesel engine water pump, small make up you clean up the matters needing attention in the diesel engine pump installed correctly.

a, diesel oil pumping unit pump correct installation steps: 1. Check no damage for diesel engine water pump and motor should be. Diesel engine water pump installation height, and hydraulic losses of suction pipe and its speed can, shall not be greater than allow the vacuum suction height value of the sample. Base size should comply with the installation of the pump unit size. 2. The diesel engine water pump on the concrete foundation with anchor bolt, by adjusting the intervening wedge block method of correction levels, and tighten around in case. 3. After the foundation and foot pump pouring concrete. After being concrete dry solid, tighten the anchor bolts, and to check the levelness of the diesel engine water pump. 4. Correction of motor shaft with the diesel water pump shaft concentricity. Make the two axis into a straight line, two axis on cylindrical coaxial degree tolerance is zero. End of the 1 mm, uneven degree 0. 3mm( After join in and out of the conduit road and commissioning respectively, check it again, still should sign the above requirements) 。 5. After to consistent with the diesel engine water water pump to check motor, coupling and coupling dowel pin. 6. In and out of the water line should be on the brace, and may not borrow diesel engine water pump pump bearing of ontology. 7. Diesel engine water pump and pipeline junction between mesa, should guarantee the good air tightness, especially feed line road, must ensure strict not leak, and no litter storage air. 8. Such as diesel engine pump installed in the water level above the water ', in order to fill pump starts, can generally be bottom valve. Also can adopt the method of vacuum water diversion. 9. Diesel engine water pump and water pipe, generally need to gate valve and check valve ( Lift can not less than 20 meters) Check valve installed behind the gate. The installation of the above method refers to not display the public base of diesel pump unit. 10. Diesel pump installed along the public base, by adjusting the base iron and wedge between the concrete foundation to calibration level of the unit. Then in the concrete. Its principle and installation requirements, and does not match the public base at the same unit.

2, diesel oil pumping unit pump use notice: 1. Before starting, turn the diesel pump rotor, light should be uniform. 2. Shut out of the water gate, to pump injection ( If there is no bottom valve with the vacuum pump water diversion) To ensure the pump inside is full of water. There is no air nest. 3. If the diesel engine water water pump is equipped with vacuum gauge and pressure gauge. To shut down its XuanJi again starting motor connected to the pump. To normal speed and then open the water valve, such as flow set is too large, can be appropriately adjusted down gate valve; Whereas traffic hours. The gate open. 4. Evenly tighten the packing gland on the gland nut, by drops of liquid leakage, temperature rise at the same time pay attention to the packing chamber. 5. When stop diesel engine water pump operation. To close the vacuum gauge and pressure gauge cocks and gate, on the road in the outlet pipe. Then close the electrical condition of the motor at low temperature, the diesel engine water pump should be open a square plug at the bottom of the pump body, remove residual water, so as to avoid frost crack. 6. Improve the diesel engine water pump speed arbitrarily, but could be used to reduce the speed. 7. Diesel engine water pump bearing the highest temperature should not exceed 75 ° C. 8. Lubrication bearing with the amount of calcium base butter to about a third of the bearing body space - It is advisable to 1/2. 9. When packing wear appropriate compression packing gland, if excessive wear should be replaced. 10. Pillars on a regular basis to check diesel engine pump 眹 shaft parts, pay attention to the temperature rise of motor bearing. 11. Operation process, such as noise or other abnormal sound, should immediately stop to check the reason. 12. Stop using diesel engine water pump for a long period of time, open dry, the water on the water pump will be another piece in processing the surface coated with anti-rust oil keep.
