Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.
Q:Why should the pump be closed when the centrifugal pump is started?
Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.
Q:What are the problems that should be paid attention to when using vacuum pumps?
What are the problems that should be paid attention to when using vacuum pumps?
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
2, the change of working volume is periodic, and in each cycle, the oil absorption process is changed from small to big, and the process of oil pressure is changed from large to small;3, suction oil cavity must be separated from each other without interference.
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:Why should I pump the pump before starting the centrifugal pump?
Before the operation of the centrifugal pump, the pump must be filled with water, exhaust the air, before you start the operation. All centrifugal pumps should be handled this way, which is the centrifugal pump itself.The way of water diversion:1., in the centrifugal pump outlet increase water diversion pump (usually using vacuum pump), start the centrifugal pump before, start the vacuum pump, the centrifugal pump air into;2. increase the vacuum water tank before the intake of the centrifugal pump to meet the working conditions of the centrifugal pump;3. in the centrifugal pump inlet water increase valve, to meet the working conditions of centrifugal pump;4., if the water tank or water tank volume of water level is higher than the centrifugal pump position, the first operation of the front row empty, usually do not empty, you can use.
Q:What are the characteristics of the piston pump?
main features 1 、 double plunger structure, small pressure pulsation, long life of gem ball.2 、 imported precious stones and precious stones to ensure accurate flow.3, through the RS232 interface and computer communication, can be directly controlled by the computer.
Q:What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
Q:What are the main performance parameters of the pump?
RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power
Q:What is the difference between the ground pump and the pump in the commercial concrete?
Day pump: the pump and pipe will be placed in a position on the site, the pipe in the air like the crane arm
