Some advantages of an inventory plunger?
With the continuous progress of science and technology, all walks of life have also been greatly developed. The development prospect of plunger is also very good, so the demand is increasing, and many manufacturers have been added to the market. As a manufacturer, it is also necessary for us to talk about the advantages of flexible cable fire prevention. Interested partners can come and have a look.
We also have a lot of problems with you before using this plunger, so if you want to use it better, you must understand some of its knowledge points. First of all, you should be clear that the plunger product is mainly a positive displacement rotary piston displacement valve, which is composed of two single-ended pistons and a double-ended axial piston. The valve has two oil inlets and two oil outlets. The oil outlet is a one-way valve, the outlet is a two-way valve, and the inlet is a throttle speed controller, equipped with a spring, so that the crankshaft can move freely within the entire load range. When in use, it is mainly composed of two parts: sealing sleeve and sliding tile. There are three parts on the gland, 0.75mm, 0.35mm and rings with hole diameter of 0.1mm are used to install three different seals (rubber O-ring elastomer polyurethane compound). In fact, the plunger slide shoe assemblies are installed at both ends of the crankshaft and rotate with the crankshaft. At present, its structure mainly includes eccentric wheel, piston, spring, cylinder body and two one-way valves. A closed space is formed between the plunger and the cylinder bore. Every time the eccentric wheel rotates, the piston moves up and down once, moves downward to suck in oil, and moves upward to discharge oil. The amount of oil discharged per revolution of the pump is called displacement, and the displacement is only related to the structural parameters of the pump.
When the plunger is working, under the action of the cam and piston spring on the crankshaft of the fuel injection pump, the piston is forced to rotate up and down to complete the task of pumping oil. The pumping process can be divided into the following three stages. Therefore, the conclusion of the plunger is mainly that the total stroke L of the reciprocating motion is constant and is determined by the lift of the cam. The fuel supply per cycle depends on the stroke, is not controlled by the camshaft, and is variable. When working, it does not change with the change of oil supply when starting. If you use it, you can still change the fuel end time, thereby changing the fuel supply. In fact, it is mainly based on the different requirements of the single-cylinder power range of the diesel engine for fuel supply, according to the stroke of the piston, the center distance of the pump cylinder and the structure type, and then equipped with piston diameters of different sizes to form a variety of fuel injection pumps with different circulating fuel supply. Can meet the needs of different diesel engines. The plunger is composed of four main parts: sub-cylinder, oil volume adjustment mechanism, transmission mechanism and pump body. It is intelligently controlled by a microprocessor, displayed on the LCD screen, and can communicate with the computer. It has the characteristics of stable working pressure, small pulsation and convenient operation. But it is also widely used in biochemical, pharmaceutical, chemical, environmental protection and other industries.
The content of the above article is some of the advantages of plunger. If you don't know these things, come and learn them quickly. I hope it can help more friends. The next issue will bring more wonderful content. If you don't understand anything, you can consult us at any time.
