SK-DSeries
SK-D series of plastic machinery industry is the ideal vacuum pumps, vacuum pump SK is based on the specific requirements of the plastics industry developed. The suction pump to solve a lot of water in the conditions can not be continuous, severe hard water scaling can not start down a long time and so on. Widely used pipe machine, profiles and other equipment.Items:SK-2D、SK-3D、SK-4.5D、SK-6D,Motor power:4~11KW,extract capacity:2~6(m3/min),Limit vacuum:-0.095MPa.

Q: How to install, operate and maintain the pipeline booster pump?
The motor coil is provided with a safety protector, and when the pump is out of order or the water is not pumped, the motor can automatically break down when the temperature of the motor exceeds the prescribed value, and the motor can automatically resume operation after the temperature rise of the motor is decreased. The booster pump motor is a capacitor running type motor. When the pump leaves the factory, the rotation direction has been adjusted. If you need to replace the capacitor or re connect, press the arrow direction on the pump body to mark the connection. To ensure safety, use the three - core safety socket with ground wire.
Q: What does electromechanical vector pump mean?
It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.
Q: Why should I pump the pump before starting the centrifugal pump?
1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)
Q: What does centrifugal pump mean horizontally?
Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
Q: What is the pumping property of concrete?
Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
Q: What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
SK vacuum pump is a single-stage water ring vacuum pump, vacuum pump and motor separation, coupled with couplings, vacuum relatively low.
Q: What are the constant pressure pumps?
Chlorine booster pumpThe pressure range of chlorine booster pump is large, and different pump can be used to obtain different pressure area. The input air pressure is adjusted and the output pressure is adjusted accordingly. High pressure can be reached, gas 90Mpa. Wide range of flow, for all types of pumps only 0.1Kg pressure can work smoothly, at this time to obtain the minimum flow, adjust the intake volume can be obtained after a different flow. Easy to control, from simple manual control to fully automatic control, can meet the requirements. Automatic restart, regardless of what causes the pressure drop in the pressure loop, will automatically restart to supplement leakage pressure and maintain constant loop pressure. Safe operation, gas driven, no arc and spark can be used in dangerous situations.
Q: What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
Q: What is the difference between an air pump and a water pump?
Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q: What is the difference between centrifugal pump and self suction pump? Which is better?
In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
