Q:What is the difference between centrifugal pump and self suction pump? Which is better?

If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling

Q:Excuse me, what is the water pump from the lotus root?

Submersible sewage pump with septic tank, outlet pipe automatic coupling installation, dipping down can be.

Q:What are the differences between the sewage pump and the clean water pump?

Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.

Q:Concrete pump 125 pipe wall thickness

Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q:What is the difference between the ground pump and the pump in the commercial concrete?

Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly

Q:The water tank of the fish tank does not air out and only has the water outlet

The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.

Q:What is the difference between swashplate pump and crankshaft pump?

Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights his advantage.

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:Brief description of centrifugal pump on / off operation

First, the preparation before the start(1) carefully check the inlet and outlet pipe line, valve, flange and pressure gauge joint of the pump, whether the installation is safe, comply with the requirements, whether the flow is correct, whether the anchor bolt and other connecting parts are loose or not.(2) add lubricating oil to the bearing case, and the oil level is 2/3 of the gauge of the bearing box.

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.
