Centrifugal Pump
The first step: According to the liquid is transferred to determine the nature and type of operating conditions; At present, Centrifugal Pump on the market are transported according to the nature of the liquid can be mainly divided into the following categories:
① Water Pump: for the delivery of water and physical and chemical properties [...]
Centrifugal Pump
before you start to note the following aspects:
a. pre-inspection
Lubricants name, type, whether the number of the major performance and filling in line with the requirements of technical documents;
Bearing lubrication system, sealing systems and cooling systems are intact, bearing the asphalt, water is smooth;
Moving the pump rotor disk 1 ~ [...]
Centrifugal Pump flow adjustment
Of a pump, the characteristic curve will not change, while the variable pipeline characteristic curves. When the pump’s operating point provided by the traffic does not meet requirements under the new conditions of flow, which should try to change the location of pump operating points, namely, the need for traffic conditioning.
[...]
Centrifugal Pump Unit by affecting the efficiency of the factors analysis and propose improvement measures to enhance the Centrifugal Pump operational efficiency and reduces energy consumption.
1, affecting the efficiency of Centrifugal Pump group of several factors
Centrifugal Pump efficiency is mechanical, hydraulic three kinds of volume and efficiency of the product. The efficiency of [...]
Multi-stage Pump the equivalent of several impeller mounted on a shaft at the same time series work, is to represent the number of impeller axis Pump series. Multi-stage pumps work, the liquid from the suction pipe inhalation, in order to squeeze into the impeller by a post-1
One impeller, each impeller through a liquid than [...]
Vane
Water Pump
Such pumps for liquid delivery depends on the pressure with high-speed rotating impeller blades and complete. Fall into this category are Centrifugal Pump, Axial pump, Mixed-flow pump and so on. Their axial impeller inflow direction Jie Wei, the different
Out of the impeller flow direction. Centrifugal Pump in the flow under the [...]
Classification of
Water Pump
Water Pump of Lu kinds of series of variety, classification methods vary. Principles of Water Pump according to their role can be divided into the following three categories.
1. Vane Water Pump
2. Volumetric Water Pump
3. Based his type of Water Pump
The use of various types of Water Pump range is very different. Vane [...]
Circulation pump Introduction
Circulation pump: device transport reaction, absorption, separation, regeneration of the circulating fluid absorption liquid pump. Generally use the single-stage centrifugal pump. Medium-sized Circulation pump flow, in a stable working conditions, the pump flow changes relatively small. Its small head is low, only used to overcome the pressure drop of the circulatory system. Low-lift [...]
Centrifugal Pump installation technical key is to identify Water Pump installation height. The height refers to the water surface to the Water Pump impeller centerline of the vertical distance, it allows a high degree of suction on the vacuum can not be confused, Water Pump or product specifications on the nameplate marked to allow a [...]
