1.Ensure safe operation of key equipment
2.Replace lubricants and wear parts regularly
3.Strict catalyst metering pump operating procedures
4.To enhance the maintenance of the pump
According to the use of occasions can be divided into:
1. The car with the fire pump
2. Marine fire pump
3. The project with the fire pump
4. The other with the fire pump
Sewage pump is widely used in municipal engineering, factories, commercial, hospitals, hotels, residential areas and other sewage discharge, which has simple installation, small footprint, easy maintenance, no noise, etc..
Pump selection basis, should be based on process flow, water supply requirements, can be considered from five aspects, both liquid delivery, device head, liquid properties, piping layout and operating conditions, etc..
In winter, the water pump icing situation often affect the daily work, the water pump system is mostly used for self priming pumps, one to the winter easily icing on this situation, please refer to maintenance methods as follow:
1.Electrical reasons pump motor
2. Mechanical reasons
3. Hydraulic reasons
4. Hydraulic and other reasons
Centrifugal pump is composed of many parts, according to the work of the work of the various parts of the state, can be roughly divided into three types: rotating parts, fixed parts and components.
Centrifugal pump is composed of many parts, according to the work of the work of the various parts of the state, can be roughly divided into three types: rotating parts, fixed parts and components:

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 make the corrosion resistance of multistage pump are on the pond outlet.
3. As far as possible to increase
1. Pay attention to the timely replacement and supplement of the lubricating oil in the boiler feed water.
2. Pay attention to the water, the boiler feed water pump is not self suction efficiency, the need for water injection.
Fountain pump is the use of motor driven centrifugal force will be some liquid, such as the gradual introduction of the surface of the machinery and equipment, in order to create a fountain for people, but also for the surrounding environment to add a bea
1.Check the parts: hot water submersible pump impeller, ring, sleeve, bearing and others are wearing parts. The first part of the pump should be removed, check whether the vulnerability is intact. Use of damage and non qualified spare parts;

Water pump control cabinet with overload, short circuit, phase protection and pump Water Leakage, motor overheating and leakage protection function and complete state display, and have a single pump and pump control mode, multiple standby pump switching m
Electric valve is mainly used for liquid, gas and air flow of the wind system. Electric valve structure is divided into two parts, the upper half of the electric actuator, the lower part of the valve.

Heating system is commonly used to have valve, gate valve, butterfly valve, ball valve, check valve, safety valve, pressure reducing valve, pressure regulator valve, balance valve, regulating valve, etc..
1. Safety valve
2. Pressure reducing valve
3.
1. Ensure that the fluid contained in the maximum particle size does not exceed the maximum safety of the pump through the particle diameter standard.
2. The intake pressure should not exceed the maximum allowable use of the pump pressure, higher than t
Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the
Sewage source heat pump in the form of many. According to heat pump directly from the sewage heat, can be divided into direct and indirect two kinds of.
Indirect sewage source heat pump is the so-called intermediate heat exchanger or heat pump loop thr
1.Check wiring is there a problem? There is no loose phenomenon?
2. Check the pump between the various components of the normal?
3. Check the situation of lubricating oil.
4. Check whether the voltage is consistent with the rated.
Mechanical problems or reduce the efficiency of the pump operation, it will cause adverse effects on the entire plant production. The wear ring can provide protection and control of the recovery cycle of the liquid when the pump is operated under abnormal
When the pump head body of the water injection pump is subjected to an alternating load during the operation process, the fatigue crack is generated. The fracture failure caused by the pump head body, the defects of low stress should suddenly brittle frac
Mud pump in the use of the process, which is likely to occur when suction pump does not suction water, suction water slow or pump vibration situation, these water absorption is what caused the failure of it
1. Pump suction is not water, the main reason
As the study of the theory of continuous improvement and test conclusion deepening and accumulation, especially the application of the theory of two-phase flow, sewage pump, slurry pump efficiency and constantly improve the level of inevitable.
Stainless steel multi-stage centrifugal pump pump pump is equivalent to more than one single pump in series, so sometimes less than 2 to 1 still can work, not affect the pump displacement, will only change the pump head.
