Structure diagram and working principle of slide pump

Explosion proof slide pump, also known as slide pump. The characteristics of slide pumps are compact structure, small volume, uniform flow rate, stable operation, low pulsation and noise, and higher efficiency than ordinary gear pumps. Sliding vane pumps are mainly used in medium speed and medium power hydraulic systems and lubrication systems of machine tools, hydraulic presses, construction machinery, and injection molding machines. Especially widely used in machine tools. However, the structure of the slide pump is complex, the manufacturing accuracy is high, and the parts are prone to wear and tear. According to the overall development trend abroad, some slide pumps are gradually being replaced by gear pumps during the turbocharging process. There are two types of slide pumps, single acting slide pumps and double acting slide pumps. About 95% of double acting slide pumps are used in machine tools. Double acting slide pumps have a large flow rate and good uniformity. The working principle of the slide pump is that when the slide pump is working, it drives the inner rotor to rotate, and the centrifugal force generated by the rotating inner rotor causes the blades to swing outward from the inner rotor groove and slide along the inner surface of the pump body. The curves of the sliding blades, inner rotor, pump body, and end face of the bearing seat form a closed cavity. As the inner rotor rotates, the volume of the seal gradually increases from zero. The volume changes with each revolution. When the volume increases, the liquid is sucked in, while when the volume decreases, the liquid is pressurized and discharged, and the pump rotates to continuously output a uniform flow rate. The symmetrical arrangement of curves on the pump body allows for forward and reverse rotation. The top of the pump body is equipped with a valve. The outlet pressure can be adjusted in advance according to the use situation. At the same time, if there is a malfunction in the pipeline or valve components and the system pressure exceeds the set pressure of the valve, the valve will actuate, creating internal liquid flow. Pottery plays a protective role. The performance characteristics of KYB motor-driven slide pump slide pump are as follows: 1. When used as a pump for underground storage tanks, it has strong self-priming ability and a head of up to 4.5m. The sliding blades of the pump are affected by centrifugal force, mechanical thrust, and water pressure, approaching the curve inside the stator, achieving a unique pump. 3. Self adjusting slides with the same performance can slide out of the rotor slot, continuously replenishing wear without affecting the performance of the pump. This is fundamentally different from gear pumps. The design of hydraulic slides with the ability to transport shear liquids reduces the shear and agitation of the slides in the fluid when driving the pump, thereby obtaining fluid characteristics. Avoid change. 5. Reliable sealing characteristics. Considering the viscosity and characteristics of high-temperature media, a special structure mechanical seal is adopted, which is durable and highly reliable. When repairing, you can turn on the pump and restore its operation within a few minutes. Daily checks are equally simple. 7. The pump is equipped with a sensitive pressure assurance valve. If the export system suddenly shuts down, the export pressure will not exceed 0.15 megapascals. This will ensure the safety of your pump and system. The motor is not overloaded. What type of pump does a slide pump belong to? A slide pump is a rotary displacement pump that changes the volume inside and outside the oil chamber by rotating an eccentric rotor, thereby pumping oil. Sliding vane pumps are widely used for mobile or fixed installation. When the pump is combined with a universal joint or hydraulic motor, it can be installed on an oil tanker or connected to a motor or diesel engine. Can be used for metal flooring, high flow lubricators, and mobile lubricators. It is a substitute for copper gear pumps. Steps for disassembling and assembling the slide pump: 1. Preparation before starting (1) Before starting the new device, the pump body must be filled with an appropriate amount of medium oil (the conveying medium is added through the threaded hole at the end of the reflux valve). I can do it. The oil level in the pump body exceeds the pump shaft. Otherwise, it will damage the mechanical seal of the pump. During normal use, there is no need to add oil before starting the pump. (2) Turn your head to see if it meets the requirements. (3) Check the lubricating oil that has not been used for a long time, especially when inspecting the pump. If you want to move again, please add lubricating grease (calcium grease) and rotate the rotating parts by hand to make them rotate or bite smoothly. Check for any abnormal conditions, such as. Check the oil level of the commonly used pump oil cup every 30 days. If insufficient, add engine oil and press it into the bearing. (4) Check the opening and closing of the inlet and outlet valves of the pump. Cover, remove the old slide and insert the new slide for convenience.
