  • What is the difference between a hydraulic gear pump and a vane pump?
    Feb 27, 2024
    What is a vane pump? Vane pump is a common centrifugal pump in various industries and application scenarios, also known as centrifugal vane pump. A vane pump pumps liquid or gas from one area to another through its rotating blades. This type of pump usually consists of a rotating impeller, pump housing, shaft (bearing) and sealing device. When the impeller rotates, it creates centrifugal force, so that the liquid or gas is thrown to the outlet of the pump. A vane pump works like a fan. When the impeller rotates, the liquid or gas is drawn into the center of the pump, and then thrown to the exit of the pump by the action of the rotating blade. This pump is suitable for a variety of applications, including industrial, construction, agriculture, domestic use, medical equipment, automotive industry, to transport water, oil, chemicals, air and more.   What is a hydraulic gear pump? Hydraulic gear pump is a common hydraulic transmission device, should be a wide range of industrial machinery, engineering machinery, agricultural machinery and other scenes; It is used to convert mechanical energy into hydraulic energy, providing pressure and flow to the hydraulic system. Hydraulic gear pump is mainly composed of gear, bearing, housing and other components. The working principle of the hydraulic gear pump is to suck in the liquid and discharge it through the rotation of the gear. Gear pumps usually have multiple structures and a variety of materials, their advantages include simple structure, small size, light weight, high efficiency, so it is widely used in many hydraulic systems.   What is the difference between a vane pump and a hydraulic gear pump? 1. Different structures: The shell of the gear pump has a pair of internal and external meshing gears, while the vane pump is composed of a rotor, a stator and a blade. 2. Different characteristics: The volume of the gear pump is small, the structure is simple, the cleanliness of the oil is not strict, and the price is relatively cheap; However, the bearing force of the gear pump is unbalanced, the wear is serious, and the leakage is large. The vane pump has uniform flow, small leakage, and can work under high pressure, mostly used in high-power hydraulic systems; However, the structure is complex, the material and processing accuracy are required to be high, the price is high, and the cleanliness of the oil is required to be high.   If you’re looking for cost-effective and timely pump replacement options, you’re looking for us.

  • Hydraulic Gear Pump Precautions For Use
    Mar 14, 2024
    Hydraulic Gear Pump Precautions For Use: 1. It is recommended to use L-HM46 anti-wear hydraulic oil in summer and L-HM32 anti-wear hydraulic oil or hydraulic oil with similar viscosity in winter. The back pressure of the gear motor drain port should not be greater than 0.4Mpa. 2. The working oil should be kept clean. It is recommended to install an oil filter with a filtration accuracy of 80-100um in the suction pipe of the pump and an oil filter with a filtration accuracy of 25um in the oil return line. It should be cleaned or replaced regularly according to the degree of oil contamination. 3. If there is an oil filter at the oil inlet of the oil pump, it should be ensured that its effective flow rate should be greater than twice the maximum oil suction flow rate, and should be kept smooth to prevent clogging. The capacity of the open fuel tank is greater than the flow rate of the oil pump for 3 to 4 minutes, and the capacity of the closed fuel tank is greater than the flow rate of the charge pump for 3 to 5 minutes. 4. It is strictly stipulated that before the installation of the oil system begins, oil must be filled and exhausted so that the oil pump can absorb oil in time when driving and rotating. It is best to loosen a pipe joint in the pressure pipeline and move the power component. Let the oil wave flow out until there are no bubbles and then tighten the joint (pay special attention to this operation, failure to do this is the most common cause of initial damage to the pump). After installing the pump, it should be operated with no load and short-term low load for no less than 10 minutes. Avoid starting and stopping with load. 5. The temperature of the oil pump should not exceed 80°C during continuous operation, and the instantaneous operating temperature should not exceed 100°C to avoid premature aging of the sealing components.

  • How to Troubleshoot Common Hydraulic Gear Pump Failures?
    Mar 22, 2024
    I believe that all engineers have encountered various malfunctions of hydraulic gear pumps in your work. So how should we troubleshoot when hydraulic gear pumps malfunction? Here are some common troubleshooting tips: Fault phenomenon Cause Analysis Troubleshooting Oil pump does not discharge oil 1. The oil pump does not rotate, the rotation speed is low, and the rotation direction is wrong. 2. The oil pump sucks air, there is insufficient oil in the oil tank, and the oil filter is clogged. 1. Check whether the key has fallen off, adjust the speed, and correct the direction of rotation. 2. Fill the fuel tank, clean the filter, and exhaust. The pressure cannot be reached 1. The system relief valve is out of adjustment and the pressure gauge display is inaccurate. 2. The internal leakage of the oil pump is too large. 1. Repair the relief valve or pressure gauge. 2. Inspect the oil pump. leakage 1. The oil pump shaft oil seal or sealing ring is damaged. 2. The fastening bolts are loose. 1. Replace the oil seal or sealing ring. 2. Tighten the bolts. Abnormal fever 1. The oil pump is running at overspeed. 2. The load pump is not unloaded. 3. The fuel tank has insufficient oil, the capacity is too small, or the oil suction pipe is not smooth 1. Reduce the speed. 2. Unload the oil pump. 3. Increase the fuel tank volume or clean the oil suction pipeline. Noise exceeds standard 1. The oil suction pipe has high resistance or the oil suction is not smooth. 2. The oil suction pipeline or the pump shaft oil seal is leaking. 1. Replace the appropriate oil pipe or clean the oil suction line. 2. Replace the oil seal or eliminate oil pipe leakage. Exploded pump 1. Oil pump operates at ultra-high pressure. 2. The relief valve is blocked. 1. Adjust the overload protection and replace the oil pump. 2. Clean the relief valve, replace the oil pump, and readjust the overload pressure.
