Summary:
JB/T 2001.62-1999 This standard is a revision of JB 2065-84 "Electromagnetic distributor for hydraulic pump station (Pg=31.5×100000Pa)". This standard specifies the type, size and technical requirements of electromagnetic distributors for pump stations with nominal pressure of 20 and 31.5MPa. Type I of this standard is that the water inlet valve is normally open when the power is off, and is suitable for controlling the minimum liquid level valve; Type II of this standard is that the water inlet valve is normally closed when the power is off, and is suitable for controlling the circulation valve. This standard was first issued in 1984.

In the standard specification, the type of single-distributor for the system with a public pressure of 20 and 31.5M is used. There is no technical requirement for the size! In the standard type, the system is powered off and the water inlet is open. The minimum liquid level must be controlled under the appropriate pressure. The water inlet of this standard type is normally closed when the system is powered off, and is suitable for controlling the circulation valve. 2 Types and sizes
2.! The type and size of the electromagnetic distributor of type 1 shall be determined according to the source of the sewage, 2.2 The type and size of the electromagnetic distributor of type 1 shall be determined according to the provisions of Figure 2, 2.3 and the magnetic distributor is 103kB.
3 Technical requirements
3.1 The nominal pressure is 31.5MPa. The test pressure is 42MPa. The nominal pressure is 20MPa, the test pressure is 30MPa, 3.? The damping screw () of the short-stroke device is debugged It should be fully opened at the same time, and then gradually increase the damping to an appropriate level: 3.3 It is recommended to connect capacitors in parallel between each phase of the three-phase AC transformer to reduce residual magnetism. 34 In order to reduce the heating of the electromagnetic distributor type, each phase coil is connected in reverse when energized, and a resistor can be connected in series to keep the power at the bottom of the small line. When the power is off, the resistor is disconnected to prepare for starting. 3.5 The bottom plane of the electric distributor bracket should be 300 higher than the reference ground. 4 Marking example: Type II electromagnetic distributor:
