Optimization Research on Blade Pump Slider Wear Problem

Optimization Research on Blade Pump Slider Wear Problem
This paper optimizes the blade wear problem of a vane pump. The vane pump uses the blade and the slider, the positioning ring and the inner rotor core to realize the pumping and draining function of the vane. Because the vane and the slider are in direct contact with the rotary motion, Focusing on the maximum eccentricity position and minimum eccentricity position of the blade, the IS-DYNA software is used to analyze the motion of the model. At the same time, considering the rotation of the blade, the inner rotor and the positioning ring will be impacted, and the blade will be forced to vibrate. The blade is worn out against the slider, so the inner rotor and the slider structure are optimized.
The oil pump is the heart of the engine lubrication system. The oil pump draws oil from the oil sump and continuously supplies pressure lubricant to the various friction components of the entire engine. If the oil supply of the oil pump is insufficient, the engine will lack sufficient lubrication pressure, causing severe engine wear. However, if the fuel supply is kept at a very high level, it will inevitably increase the internal loss of the engine and cause unnecessary waste.
Therefore, it is necessary to provide the oil pump to supply the oil according to the demand of the engine. Therefore, with the development of technology, the oil pump provided by the actual demand of the engine for oil pressure is a variable oil pump, and the variable machine The representative product of the oil pump is the vane pump. The advantage is low cost and relatively simple structure. It can ensure the reliable operation of the engine according to the actual working requirements of the engine.

Application of Camellia Seed Oil in Cosmetics Industry

图片
Before the advent of modern cosmetics, camellia seed oil was used as a traditional skin care hair care product in East Asia to improve the moisturization, smoothness and elasticity of skin and hair. Camellia saponin contained in camellia seed oil is a non-toxic surfactant with antioxidant activity and can be applied to advanced washing products. Compared with traditional surfactants, tea saponin has the advantages of being degradable, non-polluting and non-toxic, and is a natural active agent. Camellia seed oil can also be used to make cleansing oil with a very mild effect. Microwave drying machine Cosmetic grade camellia seed oil is mainly produced by low temperature and high pressure process. It is often used as a high-end cosmetic raw material or as a massage base oil, and is widely welcomed in domestic and foreign markets. Application of Camellia Seed Oil in Cosmetics Industry

Research on Hydraulic Pump Control Technology

1 blade control technology The high-pressure energy-saving hydraulic vane pump controls the vane through the electric signal and the pilot hydraulic oil, and uses the solenoid valve to control the pilot oil to pass through the rear distribution disc, leads to the outside of the propeller shaft, and finally flows into the vane pump rotor, the pump shaft, and the vane locking mechanism.  hydraulic vane pump   The pilot hydraulic oil acts on the slide valve to press a small steel ball into the concave surface of the blade. The blade is completely locked in the blade groove of the rotor, and the sealing volume cannot be formed between the blade, the stator, the rotor and the oil distribution plate, and the blade card The pump is idling, thus stopping the vane pump oil supply cycle, reducing the drive or engine output power, and saving energy. The high pressure energy-saving vane pump is stuck in the rotor when the system does not require flow and pressure. When ...

Microwave vacuum drying of banana slices

图片
The microwave vacuum drying equipment technology was used to develop new banana drying products, and the optimum microwave vacuum drying technology for banana slices was obtained. microwave vacuum drying   The effects of vacuum, microwave intensity and slice thickness on color difference, brittleness, swelling rate and sensory quality of banana slices were studied by three factors and three levels L9 (34) orthogonal design. The technological parameters of microwave vacuum drying of banana slices were optimized by comprehensive optimization method. The quality of dried banana slices obtained by different microwave vacuum drying process parameters is obviously different. The optimum point of microwave vacuum drying process is determined as follows: vacuum degree - 80 kPa, microwave intensity 14 W/g, slice thickness 12 mm. The quality of dried banana slices obtained under this process condition is better than that of microwave drying. And vacuum frying. It is fea...
