Q:What are the differences between the sewage pump and the clean water pump?

Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.

Q:Does the reservoir water heater press the booster pump (high marks)?

In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.

Q:Why can't the centrifugal pump pump the vacuum?

Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.

Q:Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?

Submersible pump cable or motor insulation is damaged.3) motor water solution

Q:What is the pump, how to classify, mainly used in where?

Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump

Q:What is the principle of a turbopump?

The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.

Q:How accurate is the metering pump?

Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.

Q:What are the starting and stopping procedures for centrifugal pumps?

The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.

Q:Is the flow meter in front of the pump or after the pump?

After the pump, the reasons are as follows, before the pump, you pump fluid through the pump will produce negative pressure in front of the pump, negative pressure on the flow of the life of the impact, the pump will not, Suzhou first Chi meter
