1. Conditions of use


It is suitable for dual-line centralized lubrication systems with a nominal pressure of 20MPa. As a metering oil supply device, it directly drives the piston to supply oil under the alternating oil supply pressure of two oil supply pipes, completing the lubrication to each The function of quantitatively distributing grease.

The oil supply ports of the SDPQ-L series one-way oil distributor are at the bottom. The distributor piston discharges oil from the same oil supply port in both forward and reverse movements. Every time the system works, oil is discharged from each oil supply port.

The SSPQ-L series two-way oil distributor has oil supply ports on the front and bottom. The distributor piston moves forward and reverse to discharge grease from the oil supply ports on the front and bottom respectively. Compared with the SDPQ type distributor, the oil supply port is doubled. One and two ports are prefabricated under the oil supply port on the front right, and the two ports are combined into one screw plug. It is easy to change the oil outlet to an odd number, and the system piping is simple. SSPQ-L2, 3, and 4 series distributors have the same number of oil ports and the same appearance and installation dimensions, making it easy to change models and replace them.

3. Model description

4. Action description

1575962868958688

The two-line distributor has two oil inlets, which are connected to the 5a and 5b oil supply pipes respectively. When one of them is supplied with oil by the lubrication pump, the other is open to the oil reservoir.

As shown in the figure above, the grease sent by the pump is transported to the distributor 4 through the oil supply pipe 5a, enters the upper part of the pilot piston 4a, and pressurizes the pilot piston 4a. At this time, the lower part is connected to the oil supply pipe 5b. load. As the pilot piston 4a moves downward, the upper chamber of the main piston 4b is connected to the upper chamber of the pilot piston, and the lower chamber of the main piston is connected to the oil outlet. The supplied lubricant enters the upper chamber of the main piston and pushes the main piston downward. of its inferior cavityProcess lubricationThe agent is sent to the lubrication point through the oil supply pipe 6, completing a cycle of oil supply.

Switch to the oil supply pipe 5b to start the second cycle of oil supply, and the distributor piston performs the aforementioned actions in the same sequence in reverse.

Each oil supply port of the distributor is determined by the diameter and stroke of the main piston 4b. By adjusting the adjustment screw 7 and changing the stroke of the main piston 4b, the oil volume adjustment within the specified range can be achieved.

The operating principle of the SSPQ-L series distributor is the same as above. The oil supply pipes 5a and 5b supply oil once respectively, and the lower part and the front oil supply port discharge oil once respectively.



5. Instructions for use

1. The specified media must be used in the specified environment.

2. The two oil inlets of the distributor are connected to the two oil supply pipes respectively, and both sides are connected. When the oil inlet on one side is not in use, the screw plug should be plugged. The unused oil supply ports should also be plugged with screw plugs (SDPQ series).

3. When used in dusty, humid and harsh environments, a protective cover should be provided.

4. To adjust the oil supply amount, turn the adjustment screw (11) on the limiter (10) to adjust the oil supply amount within the range of the maximum and minimum oil supply amounts according to the actual needs of the lubrication point. The adjustment should be carried out with the indicator rod (12) retracted, and the locking screw should be tightened after the adjustment.

5. If the number of oil supply ports is an odd number, the screw plug (8) inside the screw plug (7) should be unscrewed and plugged on the oil supply port (3). The screw plug (7) should be reinstalled, so that the oil supply port (3) It is connected with (4), and oil is supplied from the oil supply port (4) for both forward and reverse movements of the piston.

6. The dual-line distributor is preferably installed in parallel in the system. The fuel supply pipe and distributor can be connected on the left or right. Secondly, the series installation method is used. The maximum number of series connections is not allowed to exceed three. In certain situations, Can be installed in parallel and series combination.

7. The surface in contact with the distributor should be smooth and flat, and the mounting bolts should not be over-tightened to avoid deformation and affecting normal operation.

8. The screw plugs at both ends of the distributor piston are not allowed to be disassembled without any reason. If there is leakage, tighten or replace the sealing gasket with a new one.

6. Common faults and troubleshooting methods

1. The distributor does not operate.

Check whether there is pressure oil delivery in the oil supply pipe, whether the lubrication point is blocked, whether the oil supply pipe is flattened, whether impurities enter the distributor and cause the piston hole to become rough, etc. It can be eliminated after identification.

2. There is oil leakage at the indicator rod of the limiter body.

Remove the limiter and replace it with a new oil seal. It may be that the oil seal is aging or has exceeded the specified operating environment temperature. Find out and replace it.


7. Ordering instructions

1. If the distributor is installed and used with an ambient temperature > 80°C, it must be specified in the order contract so that high-temperature resistant oil seals can be used during supply.

2. When the corresponding outlets of the SSPQ (DW) type distributor need to be combined, add the subscript after SSPQ when ordering, that is, SSPQ1 or DW- ※※ H; when not merging, the last "H" is not included.
