IHF single-stage single-suction fluoroplastic chemical centrifugal pump (IHF centrifugal pump).This pump is manufactured according to the international standard and combined with the process design of non-metal pump. Using the patented technology of turtle shell mesh lining. Compared with other similar pumps, it has the advantages of lining anti-shedding and anti-cracking. The pump body is lined with polyperfluoroethylene propylene (F46) in the metal shell. The pump cover, impeller and shaft sleeve are all made of fluorinated plastic with metal inserts as the whole and sintered. The shaft seal […]

As the use time increases, Lubrication gear pumps in the hydraulic system will have insufficient pump oil, or even not pump oil fault, the main reason is that the relevant parts wear too much. The wear parts of gear pump mainly include active shaft and bushing, center hole of passive gear and shaft pin, inner cavity of pump shell and gear, end face of gear and pump cover, etc. When the main technical indexes oil transport pumps fail to meet the requirements after wearing, the oil pump should be disassembled and decomposed, the wear parts and degrees should be checked, and the corresponding mea […]

2CY gear pump gear can be roughly divided into 45 steel,40 chromium, stainless steel, copper, etc. Different types of gear pumps have different materials and USES. Examples below are as follows :2CY and KCB gear oil pumps: this pump is suitable for transporting all kinds of lubricated liquids. This series of gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft end seal, etc. The gear is manufactured by double arc sine curve tooth form. Compared with the involute gear, the most prominent advantage is that there is no relative sliding of the tooth profile surfac […]

(1) before the installation asphalt pumps, the pump body and motor shall be checked for damage during transportation, such as whether the motor is dampened, whether the dust cover of the pump inlet and outlet is damaged, and so on, so that the dirt can enter the pump chamber. (2) asphalt pump and motor are installed on the low plate. When using the crane, the lifting rope must be suspended in the lifting ring on the bottom plate. The pump head must be hung on the flanged pipe at the inlet and outlet. (3) asphalt pump installation should be selected in dry and bright places, so as to check with […]

At present, there are many kinds of centrifugal pumps sold in the market, which can be divided into a variety of centrifugal pumps according to the use environment and flow and head parameters, such as: multi-stage centrifugal pump, double suction centrifugal pump, pipeline centrifugal pump, ISG Various types of centrifugal pumps, such as single-stage single-suction pipe centrifugal pumps, and multi-stage centrifugal pumps are one of the most common types of centrifugal pumps. A multi-stage pump is a simple series of many single-stage pumps that are combined. His output water pressure can be v […]

In general, multistage centrifugal pumps are several impeller installed on the same pump shaft, the outer side of the impeller is liquid diversion device and pump shell. However, how are the impeller groups installed in or removed from the pump? There are no more than two methods. One is to divide the pump body and the flow guide device horizontally along the axis of the pump shaft, making it into upper and lower parts. Another method is to cut the pump body and liquid diversion device into several sections along the direction of the pump shaft between the impeller and the plane perpendicular […]

Multistage pump knowledge analysis At present, sales of centrifugal pump in the market has a lot of kinds, according to the use of the environment and the capacity and head two parameters of different can be divided into a lot of kinds of centrifugal pump, such as the multistage centrifugal pump, double suction centrifugal pump, pipeline centrifugal pump, ISG type single-stage single suction centrifugal pump, etc all kinds of different types of centrifugal pump, and multistage centrifugal pump is one of the many types of centrifugal pump china-africa common. Multistage pump is simple a lot of […]

Hot water circulating pump fault solution Hot water circulating pump is widely used in: energy, metallurgy, chemical industry, textile, paper and other fields, the following are the main types of hot water circulation pump failure: not lack of water, flow, vibration noise, leakage.The following is a common problem and countermeasures, hoping to help the user. One, hot water circulating pump water? 1. Import and export valve does not open the hot water pump, in and out of the pipeline jam, abortion impeller blocking.Solution, remove the obstruction. 2. Import and export of water shortage, high […]
