The CB-B gear pump is an external-meshing positive displacement gear pump, available in straight and helical gears. It is used to transport mineral oil with a viscosity of 1 to 8° and an oil temperature of 10°C to 60°C, such as hydraulic oil, mechanical oil, and fuel oil. Hydraulic systems used in machine tools, hydraulic machinery, and engineering machinery. As the power source of the system, they can also be used as oil transfer pumps, lubrication pumps, and fuel pumps in thin oil stations, metallurgy, mining, petroleum, chemical industry, textile machinery and other equipment.

CB-B gear pump is used in the hydraulic system of machine tools to provide pressure oil for each feed and reversing mechanism, and also provides lubricating oil for each guide surface and lubrication points, such as grinders, lathes, hydraulic presses, etc.

It has simple structure, low noise, good oil delivery and self-priming performance, long working life and long service life. It is used in the low-pressure hydraulic transmission system of machine tools, the oil supply and cooling system of the thin oil station in mechanical equipment, and the lubrication system of mechanical equipment.

CB-B series gear pump usage and maintenance instructions:

1. Product usage:

This series of gear pumps are suitable for low-pressure hydraulic systems to transport mineral oil with a viscosity of 1 to 8° and an oil temperature of 10°C to 60°C, such as hydraulic oil, machine oil, and fuel oil, with a rotation speed of 1000-1500 rpm. They are used in hydraulic systems of machine tools, hydraulic machinery, and engineering machinery. As the power source of the system, they can also be used as oil transfer pumps, lubrication pumps, booster pumps, and fuel pumps in thin oil stations, metallurgy, mining, petroleum, chemical industry, textile machinery, and other equipment.

2. Structural characteristics:

2.1 The gear pump mainly consists of pump body, gear, front cover, back cover, bearings, skeleton oil seal and other parts.

2.2 The pump body, front and rear covers are made of HT250 gray cast iron, the gears are made of powder metallurgy, the pump shaft is made of 40Cr combined with steel hardening, the bearings are made of SF-1 oil-free lubricated bearings or needle roller bearings, and the seals are made of double-lip NBR (note: when the oil temperature is between 60°C and 200°C or the conveying medium is corrosive, please specify when ordering), so that the gear pump has stable performance and long life. Using helical gears, the sound will be lower.

3. Pump characteristics:

3.1 Small size, light weight, simple structure, affordable price and working.

3.2 It has good self-priming properties, no need to fill with oil when starting up, and no need to fill with oil when using it.

3.3 Easy to install, use and maintain.

4. Installation, operation and precautions:

4.1 Installation:

a If the pump shaft is connected to the motor, an elastic coupling should be used, and the concentricity should be within 0.1mm. The coupling should not be too tight or uneven in weight when rotated by hand.

b. If the pump shaft is connected to the hole, the matching clearance between the pump shaft and the hole should be between 0.02-0.03mm. Forcible knocking is not allowed to avoid the pump shaft getting stuck.

c. The diameter of the oil inlet pipe of the pump must not be smaller than or larger than the diameter of the pump. The oil inlet pipe must be as short as possible with as few detours as possible. The diameter of the oil outlet pipe must not be less than 3/4 of the diameter of the oil inlet pipe. Before installing the pipeline, the inner wall should be cleaned with high-pressure oil. There should be no hard particles and debris. A filter should be installed on the oil inlet pipe. The flow rate of the filter should be twice the flow rate of the pump. All joints in the oil inlet pipeline must be sealed and there should be no air leakage.

4.2 Operation:

a. Jog the motor and confirm whether the rotation direction of the pump oil is the same as the arrow on the sign.

b After starting up and running, check that the inlet and outlet pressure of the pump is within the specified operating pressure range of the pump.

c Observe whether there are any abnormal sounds or overheating during the operation of the pump. If so, stop the pump for inspection.

4.3 Notes:

aThis series of pumps are not suitable for transporting highly volatile or low flash point liquids, such as alcohol, benzene, etc.

b This series of pumps cannot be reversed. If you need to reverse the pump, please indicate when ordering. The model mark is: CB-B※※F series cycloidal gear oil pump.
