    What is the difference between a hydraulic gear pump and a vane pump?

    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.

    How do I choose a hydraulic gear pump?

    How do I choose a hydraulic gear pump?   Judgment of rotation direction of one-way gear pump: 1. Since the one-way gear oil pump has a unique rotation direction, using the wrong rotation direction will damage the internal parts of the product, so the rotation direction of the product must be correctly judged before use. method 1: Judge according to the hydraulic pilot pump nameplate. ① Face the nameplate of the gear pump towards yourself and observe the arrow mark on the nameplate. ②When the arrow on the nameplate points to the right, the rotation direction of the gear pump (motor) is left-hand (counterclockwise code: L). ③When the arrow on the nameplate points to the left, the rotation direction of the gear pump (motor) is right-hand (clockwise code: R).   Method 2: Judgment based on matching motor (engine) ①Facing the motor (engine) power output shaft, observe the rotation direction of the power output shaft ② When the rotation direction of the power output shaft is clockwise, the matching gear pump rotation direction is left-hand (counterclockwise code: L). ③When the rotation direction of the power output shaft is counterclockwise, the matching gear pump rotation direction is right-hand (clockwise code: R)   Method 3: judge based on the actual object. Note: Under normal circumstances: One-way gear oil inlet > oil outlet Oil inlet < oil outlet of one-way gear motor. ① Correctly determine the oil outlet of the gear oil pump (motor), place the oil outlet facing you, and observe the shaft extension of the gear oil pump (motor) ②When the shaft extension is located on the left side of the oil outlet (as shown in Figure 1), the rotation direction of the gear oil pump (motor) is left-handed (counterclockwise code: L). ③When the shaft extension is located on the right side of the oil outlet (as shown in Figure 2), the rotation direction of the gear oil pump (motor) is right-hand (clockwise code: R).   2. Common installation dimensions 1. The mounting flange and shaft extension dimensions are in accordance with the requirements of GB/T2353-2005 2. The type and size of the threaded connection port shall comply with the requirements of GB/T2878-1993   3.SAB installation standards mounting flange flange dimensions(mm) Flange height(mm) Front end cover mounting hole(mm) Common oil port and flange size(mm) Two-hole mounting Four-hole mounting SAB"A" flange ⊘82.5 6.3 2-⊘11, center distance 106   20/47.6X22.2/M10 25/52.4X26.2/M10 35/69.9X35.7/M12 50/ 77.8X42.9/M12 SAB"B" flange ⊘101.6 9.4 2-⊘14, center distance 146 4-⊘14/▢89.8 SAB"C" flange ⊘127 12.7 2-⊘18, center distance 180 4-⊘14/▢114.5

    What should you pay attention to when installing a hydraulic gear pump?

    What should you pay attention to when installing a hydraulic gear pump? After the assembly of the hydraulic system is completed, during startup and operation, it is crucial to adhere to the following steps, avoiding undue haste. Regarding the installation of the gear pump, please consider the following points:   1. Ensure that the gear pump is filled with hydraulic oil before installation and rotate the driving gear to allow hydraulic oil to enter the surfaces of other pumps.   2. The main shaft of the gear pump should not bear radial or axial forces and should use a flexible connection. In the case of special conditions involving radial or axial forces, please contact the company for customized solutions.   3. The concentricity between the main shaft of the gear pump and the power input shaft should not exceed 0.1mm. The connecting parts at both ends of the coupling should also ensure concentricity within 0.5mm.   4. The suction height of the gear pump should not exceed 0.5m, and the flow velocity in the oil inlet pipe should be ≤1.5m/s.   5. There should be no air leakage in the gear pump's oil inlet pipe and flange during installation, and the oil tank should not have any bubbles.   6. Before using the gear pump, carefully inspect whether the pump's inlet and outlet ports and the rotation direction are consistent with the label's indicated direction. Do not rotate it in the reverse direction. Verify the dimensions of the gear pump's shaft extension and the connecting dimensions of the power component (pay special attention to the effective length of the pump spline shaft to avoid damage caused by axial forces). Check the dimensions of the front cover mounting flange, gently place the pump into the corresponding hole, and then tighten the bolts. When installing flange blocks or threaded connectors at the inlet and outlet ports, use matching flange blocks, threaded connectors, and screws for installation.   7. If the pump is not used for an extended period, it should be separated from the prime mover and stored appropriately. When using it again, the pump needs to run without load for at least 10 minutes and undergo routine checks.   If you have procurement needs for hydraulic components or would like to obtain more information about hydraulic components, please feel free to contact us and state your requirements!

    How important the excavator pilot pump is?

    What is an excavator pilot pump: A low-pressure oil pump that provides a control system, including handles, foot pedals, and some control valves attached to travel motors and rotary motors. The importance of pilot pump on excavator: The pilot pump pushes the main control valve block through the pilot PPC valve to flow the high hydraulic oil from the main pump to the predetermined cylinder or motor. If the pilot pump fails, the main control valve will not work, which will affect the efficiency of the entire hydraulic system. Therefore, the importance of the pilot pump cannot be underestimated.

    What is an internal gear pump?

    What is an internal gear pump? Using the principle of internal gear meshing, there is an external gear and an internal gear, and the internal gear meshes with each other in the external gear. The internal gear on the main shaft drives the external gear to rotate in the same direction. The gears separate from each other at the inlet to form negative pressure to suck in the liquid, and then squeeze the hydraulic output through the meshing of the gears at the outlet. Because this unique structure is particularly suitable for conveying high viscosity cutoffs, the applicable viscosity range is: 0.2-1000000cp. Internal gear pumps have the following characteristics: 1. The internal gear pump can realize reverse transportation by replacing the motor steering direction. 2. The pump body of the internal gear pump can be turned, and the inlet and outlet positions of the pump body are at right angles, making it easy to adjust the inlet and outlet positions according to the selection; 3. The internal gear pump is designed with convenient inlet and outlet interfaces for insulation or cooling medium between the pump body, end cover and bearing seat. 4. The superior performance of the internal gear pump has the characteristics of less trapped oil, smooth delivery, high efficiency, low noise and long service life.   What are the applicable application scenarios for internal meshing: It can be used in engineering machinery, mining machinery, agricultural machinery and machine tools and other industries.

    Maintenance methods and measures for commonly used engineering machinery hydraulic systems

    For mechanized construction companies, the technical status of construction machinery is a direct factor in whether the company can produce normally. As for hydraulically driven construction machinery, the normal operation of the hydraulic system is a major indicator of its good technical status. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system. Correct maintenance is the basis for the reliable operation of the hydraulic system. For this reason, based on our many years of production experience, we will discuss how to maintain the hydraulic system. 1 Select the appropriate hydraulic oil Hydraulic oil plays the role of transmitting pressure, lubrication, cooling, and sealing in the hydraulic system. Improper selection of hydraulic oil is the main cause of early failure and reduced durability of the hydraulic system. Hydraulic oil should be selected according to the brand specified in the equipment (instructions for use). When a substitute oil is needed in special circumstances, its performance should be the same as that of the original brand. Hydraulic oil of different brands cannot be mixed to prevent chemical reactions in the hydraulic oil. Performance changes: Hydraulic oil that is dark brown, milky white, and has a peculiar smell is deteriorated oil and cannot be used. 2. Prevent solid impurities from mixing into the hydraulic system (the cleaning and dust-free step in this point of production is very important) Clean hydraulic oil is the life of the hydraulic system. There are many precision coupling parts in the hydraulic system, some have small damping holes, some have gaps, etc. If solid impurities invade, it will cause strain on precision parts, hairpins, blockage of oil passages, etc., endangering the safe operation of the hydraulic system. Generally, the ways for solid impurities to invade the hydraulic system include: unclean hydraulic oil; unclean refueling tools; careless refueling and repair and maintenance; desquamation of hydraulic components, etc. Solid impurities can be prevented from entering the system from the following aspects: 2.1: When refueling Hydraulic oil must be filtered and refilled, and refueling tools should be reliable and clean. Do not remove the filter at the refueling port of the mailbox in order to provide refueling speed. Refueling personnel should use clean gloves and overalls to prevent solid impurities and fibers from entering the oil. 2.2: During maintenance When disassembling the hydraulic oil tank filling cap, filter cover, detection hole, hydraulic oil pipe and other parts, avoid dust when the system oil passage is exposed. The disassembled parts must be thoroughly cleaned before opening. For example, when disassembling the refill cap of the hydraulic oil tank, first remove the soil around the fuel tank cap, loosen the oil cap, and remove any debris remaining at the joint (do not flush with water to avoid water seeping into the tank). Open the fuel tank cap only after confirming that it is clean. When you need to use wiping materials and hammers, you should choose wiping materials that do not remove fiber impurities and special hammers with rubber attached to the striking surface. Hydraulic elements and hydraulic hoses must be carefully cleaned, blown with high-pressure air before assembly, and packaged A genuine and intact filter element (the inner packaging is damaged, although the filter element is intact, it may be unclean). Clean the filter at the same time when changing the oil. Before installing the filter element, use wiping materials to carefully clean the dirt at the bottom of the filter housing. 2.3: Cleaning of hydraulic system The cleaning oil must use the same brand of hydraulic oil as that used in the system. The oil temperature should be between 45 and 80°C. Use a large flow rate to take away impurities in the system as much as possible. The hydraulic system should be cleaned repeatedly for more than three times. After each cleaning, all the oil should be released from the system while it is hot. After cleaning, clean the filter, replace it with a new filter element and add new oil. 3. Prevent air and water from intruding into the hydraulic system 3.1: Prevent air from intruding into the hydraulic system Hydraulic oil contains air with a volume ratio of 6 to 8% under normal pressure and temperature. When the pressure decreases, the air will be freed from the oil. The bursting of bubbles will cause "cavitation" of hydraulic components and produce noise. A large amount of air entering the oil will aggravate the "cavitation" phenomenon, increase the compressibility of the hydraulic oil, make the operation unstable, reduce the work efficiency, and cause the actuator to "crawl" and other adverse consequences. In addition, air will oxidize the hydraulic oil and accelerate the deterioration of the oil. To prevent air intrusion, the following points should be noted: 1. After maintenance and oil change, the air in the system must be eliminated according to the provisions of the random "Instruction Manual" to ensure normal operation. 2. The oil suction pipe opening of the hydraulic oil pump must not be exposed to the oil surface, and the oil suction pipe must be well sealed. 3. The seal of the oil pump drive shaft should be in good condition. When replacing the oil seal here, you should use a genuine "double-lip" oil seal and cannot replace it with a "single-lip" oil seal, because the "single-lip" oil seal can only seal oil in one direction and does not have The function of sealing air. After the overhaul of a Liugong ZL50 loader in our unit, the hydraulic oil pump experienced continuous "cavitation" noise and the oil level in the oil tank automatically increased. After inquiring about the repair process of the hydraulic oil pump, it was found that the oil seal of the hydraulic oil pump drive shaft was misused." Single lip "oil seal". 3.2 Prevent water from intruding into the hydraulic system Excessive moisture in the oil will cause corrosion of hydraulic components, emulsification and deterioration of the oil, reduce the strength of the lubricating oil film, and accelerate mechanical wear. In addition to preventing moisture intrusion during maintenance, it is also important to tighten the lid of the oil storage barrel when it is not in use, and it is best to place it upside down; oil with a large water content must be filtered multiple times, and the drying filter paper must be replaced after each filtration. When there is no special instrument for testing, the oil can be dropped on the hot iron plate. Only when no steam comes out and burns immediately can it be refilled.
