Widespread use of agricultural pumps (pumps), such as centrifugal pump, axial flow pump, submersible pump, mixed flow pump, in the use of existing power machinery and pump power matching unreasonable, burning machine, energy consumption and higher cost, r
Pump shell :
The role of the impeller is enclosed in a certain space for the role by the impeller suction and pressure of liquid. Pump casing made of more than a spiral case, it is also known as the spiral case. As the flow channel cross-sectional area i
Ordinary centrifugal pump transmission medium if the intrusion, generally do not need irrigation pump. Only need to open the gas valve before driving, let the media into the pump body can be. If it is a self suction pump, in the first car to fill the pump
1.Running, sliding bearing and reciprocating parts of the temperature rise shall not exceed 35 degrees, the maximum temperature shall not exceed 65 degrees Celsius; rolling bearing temperature rise shall not exceed 40 degrees Celsius, the maximum temperat
1. Reciprocating pump, gear pump, screw pump, such as the volume of the pump before the start, you must first open inlet and outlet valves.
2. The centrifugal pump at startup, should open the entrance valve, close the outlet valve, start the motor power
Zhengzhou Shenlong Pump Industry Co., Ltd will participate in INDO ICON & BIMEX + KONSTRUKSI 2016
In order to promote economic and trade cooperation and communication between China and Indonesia in construction and engineering machinery field and further
1.Check the foundation precausions, should meet the requirements; check the anchor bolts should be tightened in place; the two are looking for precision to meet the requirements.
2.The motor of the steering, should be consistent with the direction of ro
The function of the pump suction chamber is to lead the liquid in the water inlet pipe to the impeller evenly. There are three common forms of inhalation:
1.Suction chamber of conical pipe
2.Annular suction chamber
3.Half spiral suction chamber
Vertical axial flow pump belongs to the vane pump, this pump has high flow, low lift, high speed, high efficiency, small footprint, performance parameter variability, and is suitable for low water conditions etc.. Therefore, often become the pump type agr
1.Static pressure method:
This method is based on the need of pressing force on the hub axle assembly of different sizes, with clamp, Jack, a manual or mechanical press, static pressure method is usually used in the conical shaft hole. Due to the s
1.As far as possible to shorten the pipeline.
2.Without the "gun" type outlet. Because of this increase in energy delivery. At the same time to make the water outlet of the water pool is.
3.As far as possible to increase the outlet pipe diameter.
The foundation excavation in the construction of the city, and auxiliary buried underground pipes, underground water is the first problem to be solved, and the key to solve the problem is to use the pump can easily be extracted from the ground water and s
In the application of the booster pump system, the ordinary submersible electric pump is installed in the vertical vessel. In this application, the booster pump system can be used in the water injection, fluid transport, corrosion of liquid handling and d
For the classification of corrosion, there are two classification methods, one is based on the mechanism of corrosion classification, and the other is based on the causes of corrosion and image classification. According to the mechanism of corrosion, the
1.When the safety valve is arranged on the outlet pipe of the shut-off valve, should use a single gate valve, and lead Fengkai, valve should be installed horizontally, in order to avoid corrosion or loosening of the stem and the valve pin plate connection
Pump system noise is transmitted through two main ways, that is, through the spread of airborne noise through the air and through the floor walls and ceiling spread of structural noise.
Noise pump system adopting some measures although decreased, but th
Submersible pump can be placed under the water, the centrifugal pump on the ground. Here is a look at the difference between the two.
Submersible pump is a very wide range of water treatment tools. The difference is that it works in the water, while the
Multi-stage pump is a centrifugal pump, is to rely on the rotation of the impeller in the acquisition of centrifugal force. When the gas density reaches the working range of the mechanical vacuum pump, the vacuum pump is drawn out.
1.Mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or pump shaft deformation and bending, resulting in multi impeller, direct friction with the pump body, or bearing damage, it is possible to reduce the pump speed.
1.The pump after the closure, to put the water left in the water pump and a pipeline, and the external soil clean, lest the frozen water in the ice after the pump body and a water pipe burst.
2.At the end of the pump, cast iron pipe and other parts, sho
