The filter adopts high - strength wedge-shaped strainer to control the automatic cleaning of filter element through pressure differential control. When the impurity accumulates in the filter surface causes the import and export pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends out the signal to drive the anti-flushing mechanism. When backwash suction dish and filter imports are pair, the drain valve is opened, the system pressure drainage, chuck and filter the inside a relative pressure below the filter of the lateral pressure of negative pressure zone, forcing some net circulating water from the inside filter lateral flow filter, adsorption on the inner wall of the filter in the impurity particles with flow into ç©£ disc and is discharged from the drain valve. The specially designed filter causes the inside of the filter to produce a jet effect, and any impurities will be washed away from the smooth inner wall. When the pressure difference of the filter is returned to normal or the timer set time is finished, the material does not break the flow during the whole process, and the anti-washing water consumption is low, which realizes the continuous and automatic production
Some algae species are 50% or maybe more lipid oil by weight. This oil can be pressed in the algae and refined into diesel. The process for extracting algal oil, at its most elementary level, is similar to pressing an olive. Up to 75% with the oil could be squeezed from algae which has a simple mechanical press. Hexane may be used as a solvent to increase extraction as much as 95%. Once extracted, the oil is refined through transesterification. A catalyst including sodium hydroxide is when combined alcohol to create biodiesel and glycerol.
In order to motivate the team spirit, the prerequisite is to organize a good team first. A good team is not casually to members together, but to achieve a common goal, to determine the characteristics of team members, organize a good team, but the key to motivate team cooperation spirit and the starting point. A good team is to tap into the potential of team members and inspire each member's potential. Potential is an explosive force! It's a source from within, and from the outside that can be invoked. The most important thing is spiritual potential, which is one's will, attitude and character. Willpower comes from desire, and the greater the desire, the greater the willpower, and thus the greater the potential. By communicating with each other, we can find the correct direction of each person and set up the true ideal, to inspire the passion and motivation of employees. At the same time, we must also break the human frailty. Every one of us has negative, comfortable, hesitant, lazy, self-governing, easy to satisfy, these human frailties, we must be resolute in restraint
1. Safety reversal: All the garage door opener designed with safety reversal feature. The door has two sensors situated six inches over the floor level, each side with the door. When any object like pet, child or some different, call light beam developed by sensor whilst the door is closing, the door stops and reverses. If your opener haven't this safety reversal feature, put it back as soon as possible.
Rail transit has long been used as public transport in cities. It plays an increasingly important role. Economic developed countries urban traffic development history tells us that only by large passenger traffic system of urban rail transit (metro and light rail), is an effective way to fundamentally improve the urban public traffic
