Technical measures to improve the pump efficiency of the pump（1）

Most oil pumpes are subject to external factors during operation, resulting in abnormal pump efficiency and a very serious impact on oil production.
The overall policy of oilfield development is to improve the comprehensive development level of oilfields and improve the efficiency of oilfields. However, as the number of oil wells continues to increase, the production volume of oil wells continues to increase, and the effect of water injection is gradually becoming obvious, but the pumping efficiency of pumps is continuously decreasing. Therefore, how to improve pump efficiency has become an important problem facing the current oilfield.
Pumping pump effect factors
Gas influence
When the pump is in normal operation, the gas and the liquid enter the pump cylinder in a mixed state, and then the gas will occupy a part of the space given by the plunger, or when the actual displacement of the pump is greater than the actual oil supply capacity of the oil layer, the formation fluid When the pump is too late to enter the pump cylinder, the actual liquid volume of the pump will be reduced, which will affect the pump efficiency. When the piston moves to the position of the bottom dead center, there is a certain distance between the discharge of the pump and the inhalation of the valve. This distance is called the anti-shock distance. The volume of the pump between the two valves is called the clearance volume.

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

图片
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...
