Professional on the proper choice of hydraulic electric pump with the continuous development of a variety of industries, and for increasing the use of electric hydraulic pump users, there are more and more users are choosing electric pump specifications, but never used the device They, and not a good choice for the electric hydraulic pump for their own use, this issue has made the following summary of its small series of selection techniques, hoping to help to you. 1, we choose electric hydraulic pump, pay attention to the removal and installation when electric pumps, the total power must intercept; 2, check the amount of oil hydraulic electric pump: Remove the tubing, the electric fuel pump wiring column turned over 11.5V voltage, the amount of glass collected from the oil port of fuel, oil pump within 30 seconds should be less than 0.6 liters, otherwise explain pump valve is faulty; 3 before damage, electric hydraulic pump, Its noise than the normal time is increased significantly, by voice can make the appropriate determination can not be performed again. 4, hydraulic electric pump armature winding resistance of generally about 10-20, if the resistance is too large or too small electric pump production, indicating that the electric pump armature winding short circuit phenomenon, bad or brush around the block Road and other failures. The production of electric hydraulic pump which category the user electric hydraulic pump and other related devices have applications may be understood, it is both lightweight and compact pump is a kind of a shell made of aluminum-containing material an oil pump disposed in the housing and moveable molding, wherein the electric hydraulic pump moveable molding material at least partially formed from a sintered, comprising at least an austenitic iron-base alloy to use the electric pump, and wherein formed from a sintered material of the molding having a thermal expansion coefficient at least for the thermal expansion coefficient of the housing 60%. Also with the continuous improvement of the production technology, the current supplied inline electric hydraulic pumps, distribution type and monomer three categories, regardless of what kind of lies in a "pump" character, quantity, pressure and time must be very accurate, and automatic adjustment according to the load. Thus to see the application of the product for the majority of users of first choice.
