• Internal Gear Pumps: Good Suction Capacity

  1 membre

  The gear pump is compact and simple, with a limited number of moving parts. Gear pumps cannot match the pressure generated by reciprocating pumps or the flow rate of centrifugal pumps, but they have higher pressure and throughput than vane pumps or lobe pumps. Internal gear pumps have better suction capacity than external gear designs, and although the applicable range is from 1 cP to more than 1,000,000 cP, they are more suitable for high viscosity fluids. Since output is proportional to speed, internal gear pumps are usually used for metering and mixing operations. The internal volume is small, and the liquid flowing through the pump can be reliably measured to achieve precise flow control. Internal gear pumps can be designed to handle corrosive liquids. Although they are usually made of cast iron or stainless steel, new alloys and composite materials enable pumps to handle corrosive liquids such as sulfuric acid, sodium hypochlorite, iron chloride and sodium hydroxide.

• The Working Principle Of Oil Pumps

  The Oil Pumps in the internal combustion engine circulates the oil under pressure to the rotating bearings, sliding pistons and camshafts of the engine. This lubricates the bearings, allows the use of large-capacity fluid bearings, and also helps cool the engine. In addition to the main purpose of lubrication, pressurized oil is also increasingly used as hydraulic oil for powering small actuators. One of the first significant uses of this approach was hydraulic tappets used in camshaft and valve actuation. Recent applications that have become more common may include tensioners for timing belts or transmissions for variable valve timing systems. Not all engines have the same fuel injection requirements. For example, a high-performance engine puts more pressure on the lubrication system. In this case, the lubrication system must be particularly robust to prevent engine damage. Most car engines on the road today do not exceed 5,000-6,000 rpm, but for high-performance engines, this is not always the case, because high-performance engines can rotate as high as 8000-9000 rpm. In this type of engine, the oil must circulate fast enough, otherwise air may be trapped in the oil. Similarly, in order to release power, some engines in high-performance applications run lighter oil, which requires less power to run the oil pump. Nowadays, the common oil weight in engines is usually 5W-30 or 10W-30, while high-performance engines may use 0W-20 oil, which has a lower viscosity.

• Hydraulic Vane Pumps: Where Is It Used?

  1 membre

  Vane pumps can be used in many different positive displacement pump applications. They can handle thin and low viscosity liquids such as water and gasoline. They are not suitable for highly viscous fluids because higher viscosities prevent the blades from moving freely in the groove. Because they can handle a variety of viscosities, vane pumps are commonly used in gas stations, fuel transportation vehicles, solvents, alcohol, and even soft drinks and syrups. Vane pumps come in many different configurations and can also handle fluids with a wide temperature and pressure range. Because vane pumps are commonly used to pump clean hydrocarbons including gasoline and light oil, vane pumps are usually made of ductile iron casings and metal rotors. The blades are usually made of carbon, which has good lubricity to keep the blades sliding in the groove and cling to the inner surface of the shell. The type of fluid being processed plays a large role in whether the pump is suitable for a particular application. High viscosity or thicker fluids will obviously greatly reduce the speed of the pump, so the vane pump may not be the best choice. In some cases, vane pumps are a good alternative to gear pumps and can pump relatively low viscosity oils. The vane pump usually works in the following range: Flow range between 20 and 9500 lpm The total head (pressure) range is 1 to 14 Bar Horsepower between 1 and 300 hp Zhejiang Yongling Hydraulic Machine Co , Ltd . is a professional large-scale manufacturer and supplier of Hydraulic Vane Pumps and V/Vq Series Vane Pumps .

• Structural characteristics of vane pumps

  The Vane Pumps is a positive displacement pump. Its working principle is to use rectangular blades to move back and forth in the groove to move the fluid. They are sometimes referred to as sliding vane pumps. A simple vane pump includes a circular rotor that rotates in a larger circular cavity. The centers of the two circles are offset, causing eccentricity. The blades are allowed to slide in and out of the rotor and are sealed at all edges to form a blade chamber to complete the pumping work. On the intake side of the pump, the volume of the vane cavity is increasing. These increasing volume vane cavities are filled with fluid driven by inlet pressure. The inlet pressure is actually the pressure from the pumping system, usually just atmospheric pressure. On the discharge side of the pump, the volume of the vane cavity decreases, forcing fluid out of the pump. The function of the blade is to expel the same volume of fluid with each rotation. Generally, the pump mechanism includes a cylindrical rotor rotating in an asymmetrically shaped housing or cavity. Cylindrical rotors usually have many rectangular slots extending linearly along the outside of the cylinder. As the rotor rotates, the centrifugal force moves the blade outward so that the outer edge of the blade maintains contact with the inner surface of the asymmetrically shaped shell. In some cases, the blade may be tensioned. The asymmetrical shape of the casing allows the blades to move in and out of the slot as the rotor rotates. When the vane moves through the suction port of the pump, a vacuum is created. Vacuum is the reason for drawing fluid into the pump chamber. The fluid then moves between the vanes and is eventually forced out of the pump's discharge port. Like many rotary pumps, the direction of fluid flow can be reversed by reversing the direction of rotation of the pump.
