This standard is published; all the results are effective, and all the requirements are set. The parties who use the standard should explore the possibility of using the following standard version, JB/20U1.6—199, water system/hydraulic valve DN15B20! 19 water system relay distance Required type and size 3 Type and size
3.1 The flow rate of this standard plate pump is only -40L/n and 63L/mn, so as to meet the requirements of various presses with different forging times and force devices respectively. Each gear is divided into three assembly types according to the different output direction of the combination network, as shown in Figure 1) Type

41 All the components should be pickled before assembly, and the oil tank should be painted with oil-resistant primer. Before assembly, the tank should be connected ten times, and no rack is allowed to stop at:
43 After assembly, liquid test should be carried out to ensure that each part can be operated flexibly. There should be no tears at each seal under the test pressure. 4.4 The main filter (X1125×100-01) must be cleaned to prevent blockage and abnormal suction. 4,5 The low-efficiency liquid level sensor (1: QK-11 type) is used to control the minimum liquid level. The minimum oil level is 300mm! When the suction liquid level is at the low position, the motor is cut off: 4.6~ pressure relay [DP-63 (A) B adjusts two non-return forces, and interlocks with the electric reversing device (24DO-BI0F-T), that is, when the pressure of the pump exceeds the rated pressure of the system, the pressure device (1) acts to make the electromagnetic reversing electromagnetic fast, and the system is corrected: when the pressure of the system drops to the required pressure, the other pressure device (2) acts to make the electric circuit cut off: so that the system is restored to the system 1 working pressure.
