JCB hydraulic pump

JCB hydraulic pump refers to the hydraulic pump used by JCB machinery. JCB is a well-known construction machinery brand in United Kingdom, and the equipment it produces is widely used in construction, agriculture, industry and other fields. As the core power component of the hydraulic system, the hydraulic pump plays a vital role in JCB equipment, converting mechanical energy into hydraulic energy to provide power for various actions of the equipment.

There are various types of JCB hydraulic pumps, the common ones include gear pumps, piston pumps, etc. These different types of hydraulic pumps have different characteristics and application scenarios. For example, gear pumps have a relatively simple structure and low cost, which is suitable for occasions where the pressure and flow requirements are not particularly high; Piston pumps, on the other hand, provide higher pressures and more precise flow control, and are often used in equipment that requires high power performance.

In the market, original JCB hydraulic pump accessories can be purchased, and there are also some JCB hydraulic pump products produced by authorized or third parties that meet the relevant standards are available. If the hydraulic pump of the JCB equipment is faulty or damaged, it needs to be repaired or replaced in a timely manner to ensure the proper operation of the equipment.

Here's how to determine the cause of JCB hydraulic pump failure:

First. Observe the appearance

1. Check the surface of the hydraulic pump for obvious damage, cracks or oil leakage. If there is an oil leak, it is possible that the seal is damaged or improperly installed.

2. Check the connecting lines and joints for looseness and leakage, which may lead to insufficient pressure in the hydraulic system.

Second. Listen to the sound

 1. The sound of the hydraulic pump in normal operation is relatively stable and uniform. If you hear unusual noises, such as crashing sounds, friction sounds, etc., it may be that the internal parts are worn, damaged, or foreign objects have entered.

2. Excessive noise may also be caused by the vibration caused by the unstable installation of the hydraulic pump.

Third. Check the pressure

1. Use a hydraulic pressure gauge to measure the working pressure of the hydraulic system. If the pressure is lower than the normal range, it may be that the output flow of the hydraulic pump is insufficient, and the reason may be that the pump is worn internally, the seal fails, the distribution plate is damaged, etc.

2. Large pressure fluctuations may be a problem with the variable mechanism of the hydraulic pump, or air entering the system.

Fourth, observe the flow

1. Check the action speed of hydraulic actuators (such as hydraulic cylinders, hydraulic motors). If the action is slow, it may be that the flow of the hydraulic pump is insufficient.

2. The actual output flow of the hydraulic pump can be measured by the flow meter, and compared with the rated flow rate to determine whether there is a fault.

Fifth. Check the temperature

1. Measure the housing temperature of the hydraulic pump with a thermometer. If the temperature is too high, it may be that there is too much friction inside the hydraulic pump, the viscosity of the oil is not suitable, or the heat dissipation is poor.

2. Overheating may lead to problems such as accelerated aging of hydraulic pump seals and deformation of parts.

Sixth. Check the oil

1. Observe the color and cleanliness of the hydraulic fluid. If the oil is blackened, cloudy, or has impurities, it may be that metal particles from the wear inside the hydraulic pump have been mixed into the oil.

2. Regularly test the viscosity, acid number and other indicators of hydraulic oil, and the oil that does not meet the requirements will affect the performance and life of the hydraulic pump.
