(1) Check whether the scratches and corrosion phenomenon plunger, when necessary, replacement of new products. (2) Check piston pair cope with the situation. The plunger tip insert the plunger comprising a tilt of about 60 °, if the plunger can slow the decline in its role as a good fit. (3) Check the tightness of piston pair. Hold the plunger sleeve, two fingers to block the plunger tip and the side of the inlet. With the other hand a ram, a larger suction felt relaxed immediately retract the plunger in place, show piston secondary seal is good, or should be replaced piston pair. (4) Check the oil valve Deputy vacuum ring worn a step or injuries phenomenon, when necessary, be replaced. (5) check out the situation with the deputy of the valve. Use your fingers to block the valve under the hole, with the other fingers to gently press down the oil valves, high pressure radial piston pump, when the finger from the upper end of the valve when it automatically springs back into place, show Deputy sealed outlet valve, the valve should be replaced or deputy. (6) Check tappet. Standard gap between the fuel pump body and the tappet is 0 ~ 0.03mm, such as more than 0.2mm, replace the parts. Gap (7) Check the plunger flange and the control sleeve between the grooves, should be 0.02 ~ 0.08mm, such as more than 0.12mm, you must replace the control sleeve Product introduction: This series radial piston radial press plunger number of planes arranged into a single row, double and three rows of three, each row may be arranged up to seven plunger. Fully enclosed pump housing can be installed inside the tank can also be installed on the external fuel tank, Texas radial piston pump, according to user requirements, Jixian radial piston pump, the pump can be formed with an outlet to be formed with several independent exports, output flow from each of the oil port and allowable working pressure is determined by the output port is connected with the number and diameter of the plunger. Features: This series pump features are: small size, light weight, electric radial piston pump, simple structure, easy installation, high volumetric efficiency, self-absorption and good performance, small vibration, low noise, stable quality, long life. Hydraulic Lu (Figure), double radial piston pumps, radial piston pump is provided by the Texas Jixian Lu hydraulic equipment factory. Texas Lu force hydraulic machinery plant (www.luliyeya.com) located in Dezhou City, Shandong Province, seven West Industrial Park. Scraps and development in the wave of market economy, the current Lu hydraulic force has a high profile in the hydraulic machinery and parts, and enjoy a good reputation. Hydraulic Lu made the whole network business alliance certification, marking our service and management level has reached a new height. Lu Hydraulic staff willing to work with all people of insight and common development, for a better future.
