For sewage pump is the most critical problem is the reliability problem, because the use of sewage pump occasions in the liquid; transport medium is some mixed liquid containing solid materials; the close proximity of the pump and motor; pump for the vert

The sewage in the 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 transmission.

Classification of clear water pumps:
1. Self suction water pump,
2. The water filling type clear water pump,
3. Submersible water pump.

Centrifugal pumps rely on the role of the rotating impeller of the liquid to the mechanical energy of the original machine can be transferred to the liquid. Due to the effect of the liquid from the impeller inlet flow of exports, the velocity and pressure

How to allow the centrifugal pump to achieve automatic water absorption:
1. Water storage water filling,
2. Selective self priming pump,
3. Pump before the water tank water diversion method,
4. Using engine exhaust vacuum filling method.

The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, seal ring, stuffing box.

Pipeline centrifugal pump installation technology is the key to determine the installation height of the pump (ie suction process). The height is the vertical distance from the water surface to pump impeller centerline, it and allow the ceiling should not

1. After the pump is removed, the sequence can be decomposed
After the decomposition of parts should be cleaned, and then one by one check to see if there are cracks, damage and wear and other defects, if there is a serious defect, should be replaced. I

1. A group of fire pump unit, the water suction pipe should not be less than two, when one of the damaged or repair, the remaining water absorption pipe should still be able to design through all the fire water supply;
2. Fire pump unit suction pipe ar

Axial flow of deep well pump should be installed in the well, the submerged depth should meet the requirements for its reliable operation, in the pump unit flow for the design flow of 150%, the minimum submergence depth should be is the first water pump i

1. Water pump unit casing is suitable for ductile iron;
2. The impeller is suitable for bronze or stainless steel.

1. Fire pump unit performance should meet the requirements of the flow and pressure of the fire water supply system;
2. The power of the pump unit of the fire pump unit shall meet the requirements of any point on the performance curve of the flow head pe

Pump operating point selection in optimal operating point on the left. This is to allow the operating point offset to the right (which in the actual operation is inevitable), to prevent the pump unit "real" work transcends pump manufacturing plant given

Circulating water is too large, it is a common problem in our country, and its capacity is often 2-4 times as much as the actual needs. The reasons are various.

The hot water heating system is a systematic project, and the neglect of any part of the system will seriously affect the heating effect of the system. Circulation water pump is the key equipment, connecting the heat source, heating and indoor heating sys

When selecting the pump unit, it is not important to distinguish the performance of the pump unit, the power is not important, but the efficiency of the unit. In the same head, the same flow rate, the small power efficiency, it also shows that the perform

Mixed flow pump from the shape and structure are between the centrifugal pump and axial flow pump.

Mixed flow pump principle, the high speed rotation of the impeller, both the centrifugal force generated by the centrifugal pump, but also with the axial

Mixed flow pump is a kind of pump between the centrifugal pump and axial flow pump. Mixed flow pump than the speed higher than the centrifugal pump, lower than the axial flow pump, generally between 300-500. Its head is higher than the axial flow pump, bu

Four methods to solve the faults of motor of self priming pump:
1. After the power is connected to the pump is still not working,
2. Bad start or start when there is noise,
3. The motor to run, but the speed is slow, the housing overheating, burning,

1. Check the self suction pump and the pipeline and the combination of the loosening of the phenomenon. Hand rotating self-priming pump self-priming pump, it is flexible.
2. To the bearing body join the bearing lubricating oil, to observe the oil level s

The pump is characterized by simple and reliable structure, durable. Under normal circumstances, generally do not need to open maintenance. When the failure is found at any time to be excluded .

This series self-priming pump, according to the work of the pump operating conditions, respectively, using high-quality calcium base grease and 10 oil lubrication, if the lubricating grease pump should be regularly to the bearing box to add the butter, th

Self priming pump according to the principle of action is divided into the following categories:
1. Gas-liquid mixing type (including internal and external mixing);
2. Water ring wheel;
3. Jet type (including liquid jet and gas jet).

ZW type self-priming sewage pump used in chemical, petroleum, pharmaceutical, mining, paper, fiber, pulp, textile, food, power plant and municipal sewage works, public facilities, sewage pond aquaculture industry.

Self priming pump structure of many types, in which molten salt pump, vacuum pump, liquid pump, metering pumps, gear pumps, corrosion resistant pumps, acid pumps, fire pumps flow to the direction of rotation. And then right to water in the backwater hole
