Keep in mind that the electric oil pump should be kept in a dry, clean and non-corrosive atmosphere. Gear pump pay attention to insulation resistance, long-term shelved or used in humid environment, electric pump, must be measured before use 500 V ohm meter winding insulation resistance. If the insulation resistance between the winding and the motor housing is less than 7 megohms, the winding must be dried. Keep each part and replace the same parts, the demolition of the gear pump, you should keep each part, pay special attention to the explosion-proof parts of the explosion-proof surface can not damage the hairline, including insulation pads and casing, if damaged, Must be replaced on the same new parts, shall not use less than the raw material function of alternative materials or parts of the original specifications do not match, assembly should be all parts according to the original location, can not be missed. Gear pump often check the maintenance, electric drum pump should always check, repair, to check the power cord: the internal wiring, plugs, switches are good, the insulation resistance is normal, the tailstock is loose, commutator and brush in good contact , Armature-level expansion stator windings are there is a phenomenon of suitable interrupting, bearing and rolling parts are damaged and so on. Often add fat, electric drum pumps for high-speed operation, easy to volatile grease, it is necessary to make the bearing lubrication can be kept clean, and pay attention to Tim.
Phoxim insecticidal spectrum is wide and knocked out power, give priority to with tag and stomach poison effect, no inner absorption effect, is effective for lepidoptera larvae. In the field because of the light is not stable, quickly decompose, so residual period is short, the residual risk is small, but the drug in the grave, residual period is long, suitable for the prevention and control of underground pests. Dosage form, 50% and 45% phoxim ec, 50% granules.
