Linde HMR135 plunger pump accessories

2025-03-04

The power and volumetric power of hydraulic pump accessories refer to the ratio of their actual flow rate to their theoretical flow rate. For hydraulic motor components, it refers to the ratio of their theoretical flow rate to their actual flow rate. Mechanical power refers to the ratio of theoretical torque to actual input torque for hydraulic pump components. The practical output torque of hydraulic motor components is the torque obtained by overcoming frictional force with theoretical torque, therefore its mechanical power is the ratio of practical output torque to theoretical torque. The total power refers to the ratio of the output power to the input power of pump components (or hydraulic motor components). The total power is equal to the product of volumetric power and mechanical power.

The following is a knowledge sharing about the HMR135 hydraulic pump accessories for Lind plunger pumps:

Q: How are the displacement and flow rates of pump accessories determined?

Answer: Displacement refers to the volume of liquid discharged (or input) from the sealed chamber after each revolution of the pump component (or hydraulic motor component), which is commonly measured in milliliters per revolution. Parts with adjustable displacement become variable displacement pump parts (or variable displacement hydraulic motor parts), while parts with fixed displacement become fixed displacement pump parts (or fixed displacement hydraulic motor parts). Practical flow refers to the flow rate at the outlet (or inlet) of a pump component (or hydraulic motor component) during operation. Due to internal leakage of pump components, the actual flow rate is lower than the theoretical flow rate. Because hydraulic motor components also have internal leakage, in order to achieve the specified speed and compensate for the leakage, it is necessary for the actual input flow rate to be greater than the theoretical flow rate.

Q: How does volumetric power affect the use of hydraulic motor components?

Answer: Volume power refers to the ratio of the actual flow rate to the theoretical flow rate of hydraulic pump components. For hydraulic motor components, it refers to the ratio of their theoretical flow rate to their actual flow rate. Mechanical power refers to the ratio of theoretical torque to actual input torque for hydraulic pump components. The practical output torque of hydraulic motor components is the torque obtained by overcoming frictional force with theoretical torque, therefore its mechanical power is the ratio of practical output torque to theoretical torque. The total power refers to the ratio of the output power to the input power of pump components (or hydraulic motor components). The total power is equal to the product of volumetric power and mechanical power.

Q: How to repair and protect hydraulic pump accessories?

Answer: Reason for the problem: (1) Low oil level in the hydraulic oil tank; Cleaning method: increase hydraulic oil

Reason for the problem: (2) Failure to use hydraulic oil according to the season; Cleaning method: Generally suitable for 46 # hydraulic oil (or 68 #), no special replacement required. Consider using 32 # hydraulic oil when it is extremely cold in the north during winter#

Reason for the problem: (3) The oil inlet pipe is severely blocked by dirt;
