1. Overview

DRB-L series electric lubricating pump is suitable for two-line dry oil centralized lubrication system with many lubrication points, wide distribution range and high oiling frequency. The double-line distributor supplies grease to the intelligent lubrication parts, which can meet the needs of various machines and equipment, and is especially suitable for large units and production lines.

This series of electric lubricating pumps can form a two-line ring-type centralized lubrication system, that is, the main pipeline of the system is arranged in a ring. The hydraulic pressure control valve is controlled by the system pressure returned to the end of the main pipe of the lubrication pump, so that the two main pipes alternate Centralized lubrication system for supplying grease; see the outline drawing and outline dimension table. It can also form a two-line terminal centralized lubrication system, that is, a centralized lubrication system in which the pressure control valve at the end of the main pipeline controls the electromagnetic reversing valve to alternately supply grease to the two main pipelines. See also the outline drawings and dimensions Regulations.

This series of electric lubricating pump adopts double plunger mechanism, which is reliable in operation. The deceleration mechanism is placed in the pump body. It has a compact structure and small size. It can be automatically controlled by a corresponding electric control box.

6、working principle

        This series of electric lubricating pump is composed of plunger pump, oil reservoir, directional valve, motor and other parts. The plunger pump is driven by the electric motor, sucks grease from the oil reservoir, presses it to the reversing valve, and sends it out along the two oil outlets through the reversing valve. The other oil outlet is connected to the oil reservoir for unloading.

The ring-type electric lubricating pump is equipped with a hydraulic reversing valve, which has four interfaces. It is externally connected to two oil return pipes that are respectively returned by the two oil supply pipes. to.

The terminal structure electric lubricating pump is equipped with an electromagnetic directional valve. It has two interfaces and is connected with two oil supply mains.

The operating principle of the plunger pump directional valve is detailed in the instruction manual.


7.instructions for use

        1. This series of electric lubricating pumps should be installed in a suitable environment temperature, less dust, small vibration, convenient for adjustment, inspection, maintenance and fat replenishment, and should be placed in the center of the system as much as possible to shorten the system piping length and keep low The pressure drop enables the pump to generate enough pressure to overcome the resistance of the lubrication point.

2. Before use, add N220 industrial gear oil to the deceleration chamber of the plunger pump to the level specified in the oil standard.

3. To replenish oil into the oil reservoir, use an electric refueling pump to replenish it from the supply port of the lubricating pump. The grease used should be clean and no dirt is allowed to be mixed.

4. The rotation direction of the lubricating pump is unidirectional, and it must be used in accordance with the rotation direction specified by the rotation direction card on the motor.

5. The standard set pressure of the pump relief valve is 23M P a, which can be arbitrarily adjusted within the range of 0 ~ 20M P a. It is not allowed to exceed 15% (23MPa) of the nominal pressure of the pump when in use.

6. The setting pressure of the hydraulic reversing valve of the ring lubrication pump is adjusted according to 5MPa.

7. This series of electric lubricating pumps are installed indoors. When used outdoors or in harsh environments, protective measures must be taken.
