Specializing in the production of 2D-SY electric test pump manufacturers in what?

Use 1, the installation out of the box (1) Install the wheel. The four suits in the wheel axle (washer 20 at the wheel on both sides), put the cotter pin. (2) Install a safety valve. Twist to the sump plug packaging, the safety valve in the sump of the safety valve connectors M14 × 1.5-5H hole (note plus copper washers 6). (3) Install the pressure gauge. Pressure gauge pressure gauge screwed into the next nut connector, easy to observe the surface facing the direction of the maximum value shall be equal to 1.2-1.5 times the gauge pump rated pressure. 2. Use (1) Preparation before use: ① reduction box to add a little oil, so the oil reaches the upper or lower limit of the oil standard position. Black gear lubricant oil. ② on both sides of the transmission case 30 by the fuel injection signage machine oil, the oil should be slightly higher than the lower part of the crosshead guide surface, long-term continuous use should pay attention to add. ③ Check the fastening bolt without loosening. ④ inside the tank to fill clean working medium, and should pay attention to the filter may not be out of the water. ⑤ subjects vessel should be pre-filled with the working medium. ⑥ container line will be tested and work catchment good header. (2) should be precautions: ① the highest gear box oil temperature should not exceed 80 ℃. ② work, such as a pump or other parts found significant leakage, should be immediately removed. ③ When the relief valve can not be used. ④ boost process, if the pressure gauge needle swing too, indicating the user is test pressers volume is too small, then the best in the system connected to a pressure vessel of sufficient capacity (should comply with the relevant national standards) or Other appropriate energy storage devices. Then jog boost pressure test pieces when ⑤ if they are large volume, continuous operation can be boosted to be close to the test pressure. During operation the system pressure should pay close attention to avoid accidental overpressure. ⑥ If accidentally unexpected overpressure, can play an open valve, after removing some of the pressure to re-boost. (3) Procedure ① Open the drain valve. ② start the motor, operating at atmospheric pressure for 5 minutes, check the pump operation is normal. If there is no abnormal noise and blocking phenomenon, suction, exhaust normal and no significant fluctuations in the pump delivery of the working medium to close the drain valve, turn on the pump pressure test. When ③ When the pump discharge pressure at or near the required pressure value, that should be shut down. ④ pipeline pressure test pump can also be installed outside the cut-off valve and drain valve, cut off the container, so that was the test piece in packing state. ⑤ after pressure test is completed, the pressure relief valve open play, the working medium back into the tank. (4) test pump coupling dimensions: a sump pump center line at 770 mm above the ground, equipped with joint work, about the size as shown in Figure 2, please click here Dimensions arrangements pipeline connected users.
