Steering error
If the pump flow and head are lower than the normal value and the motor current is less than the normal value, the pump is a new installation or just change the motor, often this phenomenon. When the pump flow is not enough, we must first

Method for single stage centrifugal pump water intake and exhaust
Because the centrifugal pump impeller on the pump water extrusion formed after vacuum water, so in addition to the impeller leaching in water centrifugal pump and self suction pump, genera

Select suitable pipeline centrifugal pump models correctly calculate the pipeline flow and head, and make the selected pump rated flow and head is equal to or slightly larger than the pipeline flow and head of the centrifugal pump working in high efficie

Technical treatment of water pump and analysis of common fault source. There are two main fault: 1.Vibration in operation; 2.Noise increases in operation

Submersible pump is an important equipment in the deep well water extraction. When using the whole unit into the water work. Submersible pump in the use of the choice is very important, should be based on the actual situation of water and work time and th

Stainless steel submersible pump is suitable for mine, factory, building, deep well water, chemical liquid, medicine, food processing and other applications. Especially suitable for the mining industry, agriculture, construction, aquaculture, food and bev

1. Is strictly prohibited without the medium idle, please be sure to start before driving into lubricating medium or medium.
2. All the debris into the pump cavity is prohibited, be sure to keep the pump cavity and the cleanliness of the inside of the pi

1. The assembly should be carefully cleaned, check the parts of the screw pump, the damaged parts should be replaced;
2. Transmission shaft two universal joint assembly, should check whether the sealing ring is damaged, filled with grease in the cavity;

1. Vacuum pump in the process of operation, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature shall not exceed 80C.

Self priming pump is a collection of self suction and non clogging sewage in one, the use of axial flow of the mixed, and through the pump body. The unique design of the impeller, can transport water can also be sent to the particles and fibers of sewage

Known water ring vacuum pump is the equipment supporting the use of equipment, presents the shortcomings often affect the group produced the smooth operation of the link, such as pump know reality principle, can be judged by oneself the cause of its short

Speed is the number of times the pump shaft or impeller rotates per minute. N is usually expressed as a symbol, the unit is to turn per minute (r/min). Performance parameters of the pump speed and the other has a close relationship, a certain speed, resul

Pipeline sewage pump installation technology is the key to determine the installation height of the pipeline sewage pump is the suction process. The height is the vertical distance from the water surface to a centrifugal pump impeller centerline, it and a

Self priming pump with no impurities in the liquid for the water self priming pump, transport of impurities in the chemical fluid for the sewage self priming pumps and chemical pumps. Self priming pumps in water treatment plants, chemical plants, food man

Determination of the height . Reservoir fluid volume and the liquid storage: storage liquid volume refers to after stopping the pump, pump body can store the volume of the liquid part, is the pump suction mouth below the lowest point of the pump body vol

Pneumatic diaphragm pump is a new kind of mechanical transmission, using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, easy volatile, flammable, poisonous liquid can be pumped light absorption

Due to oil pump is linked to a long running, the user in the use of the bearing oil chamber does not often change, lead bearing long under the conditions of poor lubrication of long-term high speed heat pump bearing damage caused by, from but heat-conduct

IH chemical pump is suitable for continuous conveying any of the concentration of strong acid, strong alkali, organic solvent, strong fluoride agent and other high-risk liquid chemical media, when the transport of 5% of the content of solid particles of l

Submersible sewage pump will sewage in long fiber, bags, belts, grass, cloth and other material tear, cut, then smooth discharge, especially suitable for hard solids, fibers, liquid and particularly dirty, sticky, slippery liquid contained in the transmis

QJ well submersible pump is a motor and pump straight league one dive into water submersible multistage pump of water equipment. It is used to from a deep well groundwater extraction, can also be used for rivers, reservoirs, canals and other water lifting

Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reversal, as well as the release of the container medium. Check valve can also be used to give the pressure may rise to more than the system

Self suction pump in the pumping pipe is the case of air, the use of pump work, the formation of the negative pressure (vacuum), the role of atmospheric pressure will be lower than the water pressure up, and then discharged from the pump drain. This proce

Submersible pump installation first before the installation of submersible pump carefully calculate the installation height, preferably coupled with a high margin of at least 0.3m, the installation height should be lower than the calculated value. How to

When assembled, all screw threads and nuts are coated with a layer of oil powder. After the last stage impeller is assembled, the axial distance between the two ends of the wheel hub and the wheel hub is measured, and the axial dimension of the spacer sl
