Q:Is the vacuum pump air compressor?
A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
Q:What is the Rhodes pump?
The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
Q:What does the impeller on the centrifugal pump mean by the first cutting?
So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.
Q:Why is the submersible pump tripped on an electrical switch?
Submersible pump cable or motor insulation is damaged.3) motor water solution
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:Suction stroke and lift of water pump
For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.
Q:What does "anti pump" mean in pump operation?
The pump again is the pump, the theory is the plugging problem can be solved, but if you are against the pump after pump has been plugging serious, and pump has been unable to solve the plugging problem, finally the worst solution is a split pipe, if the situation under enormous pressure will only exacerbate the plugging
Q:Fire control center manual start fire pump directly, multi line control
The line between the fire pump buttons should be NHBVR-4*1.5 lines. 2 start, 2 answer. Some manufacturers reported that the 3 lines can also, this need to see which is the specific equipment. In addition, we need to introduce 2 warning buses.The above lines are individually distributed
Q:How to adjust the flow of piston pump?
For the swashplate valve controlled by the solenoid valve, the swashplate is in an angle with the cylinder body, so the plunger is reciprocating in the pump cylinder when the cylinder rotates. It goes from 0 degrees to 180 degrees, that is, to the upper plunger position, the plunger cylinder volume gradually increased
