SSPQ-P Series Dual-Line Distributor (40MPa)

SSPQ-P Series Dual-Line Distributor (40MPa)

DISTRIBUTOR TYPE: 8SSPQ2 40 MPA 1.5 ML

SSPQ-P Series (formerly ZV-B Series) dual-line distributors are suitable for use in dry oil or thin oil dual-line centralized
lubrication systems with a nominal pressure of 40MPa as a quantitative oil supply device. A dual-line distributor that
alternately presses grease through two oil supply pipes to achieve quantitative lubrication of each lubrication point. The
distributor has three types: with oiling screw, with motion indicator adjustment device, and with stroke adjustment device.
1). For a distributor with an oiling screw, the oil supply cannot be adjusted. The oil supply can only be changed by selecting
an oiling screw with a different oiling index.
2). For a distributor with a motion indicator adjustment device, the oil supply can be adjusted within the range of zero to
the rated oil supply, and the normal operation of the distributor can be judged by observing the motion indicator
adjustment device.
3). For a distributor with a travel switch adjustment device, the oil supply can be adjusted within the range of zero to rated
oil supply, and the oil supply condition of the lubrication point can be controlled by sending a signal through the travel
switch. Each distributor can only have one limit switch adjustment device.

4. WORKING PRINCIPLE
The piston holes of the double-line distributor connected to each two lubrication points are respectively provided with a
control piston and a working piston. The two oil inlets are respectively connected to two oil supply pipes 3a and 3b. When
one of the oil supply pipes is pressurized, the other is unloaded.

5. INSTRUCTION FOR USE

outlets, and seal the unused oil outlet with a G1/4 screw plug. The upper and lower oil outlets are connected, and the
piston is supplied with oil from this outlet for both positive and negative movements.
7). For easy disassembly, the pipe from the distributor to the lubrication point is best bent at 90° or a ferrule joint is used.
8). The surface on which the distributor is installed should be smooth and flat, and the mounting bolts should not be
tightened too much to avoid deformation during use and affect normal operation.
9). It is recommended to use GB70-85 screws M6×50 for installation and fixation of SSPQ1 and SSPQ2 type distributors. A
30mm pad is required between the installation surfaces of SSPQ3 type distributors, and GB70-85 special screws M6×85 are
used for installation and fixation.

6. COMMON FAULTS AND TROUBLESHOOTING
1). The distributor does not work.
Check whether the oil supply pipe is delivering pressure oil; whether the lubrication point is blocked, whether the oil
supply pipe is flattened; whether impurities enter the distributor and cause the piston hole to be roughened, etc., and you

can find out and eliminate them.
2). Oil leakage at the indicator rod of the motion indicator adjustment device.
Remove the limiter body and replace the oil seal. It may be that the oil seal is in stock or has been used for too long or has
exceeded the specified ambient temperature. Replace it after checking.
