JHGS4 Cartridge Pressure Relief Electric Lubrication Pumps
JHGS4 is a pressure relief single-line cartridge type electric lubrication pump controlled by a host PLC. When the lubricant in the cartridge is used up, users only need to replace it with a standard cartridge, which is convenient for operation and maintenance.
Description
Operation
1. For JHGS4 type, please use the cartridge replacement method to fill grease. Because a strong spring is installed in the cover, when the cover is loosened, please avoid the cover popping out due to the spring force.
2. The applicable lubricant viscosity range is NLGI 000, 00, 0, 1#. When the grease volume is lower than the normal level, please replace the new cartridge immediately.
3. When using the lubrication pump for the first time or when the lubricant cannot be pumped out or the cartridge is replaced, you must first perform exhaust action through the forced lubrication function and the exhaust port according to the user manual.
4. When using the lubrication pump for the first time, fill the main pipeline and branch pipeline with grease through the lubrication pump or grease replenishing machine, and then connect the distributor.
5. When the lubricant volume of the lubrication pump is too low, please replace the new cartridge immediately to prevent the pump from sucking air and failing to pump out oil.
6. When the pressure value of the electric lubrication pump does not match the default value, you can adjust the pressure regulating valve according to the user manual.

Precaution
1. This lubrication pump uses NBR and VITON as sealing components. Do not use any lubricants that may damage these materials.
2. To prevent air from entering the cartridge, please squeeze out a little lubricant before installing it when replacing the cartridge.
3. When the lubricating grease in the JHGS4 cartridge is used up, it is prohibited to refill the lubricant and reuse it. A new cartridge must be used to replace it.
4. If the JHGS4 electric lubrication pump runs for a long time, it will cause the internal motor to be hot, which will affect the temperature of the machine itself. Therefore, the interval time of the lubrication pump needs to be set to more than 10 times the action time to allow the motor to dissipate heat effectively. For example: the action time is set to 60 seconds, so the minimum interval time setting value needs to be 600 seconds.
5. As for the time setting of the electric lubrication pump, the first lubrication action after the machine is turned on the next day after shutdown may have insufficient pressure. This is because the residual pressure inside the oil pipe has been completely released. It is recommended that the first startup action time should be more than 140% of the normal action.
