Instructions for a pump working medium YB-N32 hydraulic oil, when the ambient temperature is below 10 ℃, the use of low viscosity aviation hydraulic oil. Application 120 mesh layers of filter when refueling. 2 regardless of the pump as a motor pump is mounted in the outer diameter of the tank to the pump manufacturer, or installed in the tank as a complete pump stations, must be used to ensure that the oil level is higher than the oil filter, under the unloading state, idling 10 minutes, jog the motor several times, drain suction chamber air double radial pump before using normal post. 3 Using the strict control of the oil temperature 20 ℃ ~ 60 ℃, the ambient temperature should be below the heating measures: oil temperature higher than 60 ℃ must have cooled cooling measures. 4 regular inspection oil, particle contamination could easily lead to the plunger does not work properly or stuck, oil deterioration, performance degradation will result in loss of bearings and piston top research seriously shorten life. 5 non-operation over the set pressure. Piston pump works with a plunger to introduce the principle of a two-way valve radial piston pump, and in the opposite direction of quality radial pump, cylinder plunger appear negative movement in one direction When, then a one-way valve opens the liquid is sucked into the cylinder, the plunger movement in the other direction, the liquid compression after another one-way valve is opened, liquid is sucked into the cylinder is discharged. This way of working continuously after the formation of a continuous oil movement. Quality radial pumps, hydraulic power Lu (certified), provided by the Texas Lu radial pump hydraulic equipment plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is a leader in Dezhou, hydraulic machinery and parts, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create Lu hydraulic force a better future.
