Q: Working principle and diagram of axial piston pump with pressure compensation variable: Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.

Q: How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?: The purpose of the steam separator is to separate the gas from the liquidWater ring type vacuum pump, water, compressed gas is discharged through the exhaust port, if not it is soda water separator is discharged, can not be separated, for the recovery of gas discharged industry is obviously impossible.Soda separator is available, the key is to see the working conditions

Q: Is the diaphragm pump and the drain pump one?: Generally composed of actuators and valves.Pneumatic diaphragm pump, which has four kinds of materials: plastic, aluminum alloy, cast iron, stainless steel. The electric diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron and stainless steel. Diaphragm pump diaphragm according to different liquid media, respectively, NBR, chloroprene rubber, fluorine rubber, PTFE, poly 46 ethylene to meet the needs. Placed in a variety of special occasions, for pumping various media.

Q: What is the pump, how to classify, mainly used in where?: 1. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed and transfer mechanical energy to the transported liquidAccording to the pump impeller and runner structure characteristics can be divided into different:1) centrifugal pump2) axial flow pump3) mixed flow pump4) vortex pumps3. jet pumpA high velocity jet produced by a working fluid is used to eject the fluid, and then the energy of the ejected fluid is increased by momentum exchange

Q: How many kinds of pumps are available and the operating principles of various pumps?: The volume type pump, depending on the periodic change of sealing liquid containing space volume, the energy is periodically transmitted to the liquid, the liquid pressure increased to force the liquid discharge, according to the motion form of work elements can be divided into reciprocating pump and rotary pump. Other types of pumps transmit energy in other forms. As the jet pump work on high-speed jet of fluid will be required to transport fluid suction pump after mixing for momentum exchange in order to transfer energy; water hammer pump by water when braking in the flow of energy transfer is to rise to a certain height; the electromagnetic pump is energized to make the liquid metal in the electromagnetic forces generated in the flow and transport. In addition, the pump can also be classified according to the nature of the transmission fluid, driving methods, structure, use and so on.

Q: The main factors affecting the performance of centrifugal pumps: Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small

Q: What are the characteristics of a vertical multistage centrifugal pump?: Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.

Q: What is the working pressure of the hydraulic pump in the hydraulic transmission system?: The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.

Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.

Q: Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?: The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
