Product Description:

                   Self Priming  Diesel Engine Water Pump for Irrigation

1.Structure of Self Priming  Diesel Engine Water Pump for Irrigation Description

The pumps are designed for economical & trouble-free operation in handling solids-laden liquids and slurries, it handle up to 76.2mm spherical solids.Pumps feature a large volute design which allows them to re-prime automatically in a completely open system without the need of suction or discharge check valves. And this is workable with the pump only partially filled with liquid and completely dry suction line.Standard Self-Priming pump units are available for Solids Handling or Clear Liquid service. Typical mounting configurations areEngine Driven for Skid or Trailer Mounted packages and Frame Mounted Electric Driven.  Pumps also are available in a variety of different metallurgies.

Q:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:A direct type pump model with the coupling type, what is the difference?
The water pump type is directly connected with the motor, and the motor shaft and the pump are coaxial;Pump motor and pump shaft is separate, with the coupling power transmission.
Q:Pump adapter joint net outside tube, what is the principle?
First, the working principle:Fire pump adapter is connected with the public security fire department fire engine or motor fire pump fire water transport through the fire pump adapter interface fire water supply pipeline to the buildings, the fire hydrant indoor get sufficient pressure to solve the problem of water shortage and other difficulties or because of fire water supply pipeline inside the building due to low water pressure caused by the fire fighting for high-rise building, indoor use and normal operation of fire pumps and intermittent water supply situation in. The installation types include floor type, underground type and wall type.A brief introduction to the two, pump adapter:When a fire occurs, the fire engine pump can quickly and conveniently through the interface and building the adapter in the fire fighting equipment is connected, and the water pressure, so the indoor fire equipment pressure with sufficient water to extinguish, different floors of fire, effectively solves the problem of building fires, fire fighting because of difficulties or indoor fire fighting equipment due to lack of adequate water pressure to the fire.
Q:Electrical design into!!! Is the water pump lamp waterproof?
No specific requirements are available
Q:Is the pump lift horizontal or vertical?
The vertical height from the center line of the pump impeller to the surface of the water source
Q:What is the definition of the pump in the capacity of the pump?
Work pump, spare pump, repair pump three are interchangeable use, the work pump need to overhaul, repair pump work, work pump is maintenance pump. The capacity of the water pump is not less than 25% of the work pump. If the work pump, spare pump, repair pump model is the same, the work pump 4 units, repair pump at least 1 units, 5 pumps, repair pumps need 2 units
Q:Two pumps automatically switch start control circuit,
Do you mean that 2 pumps are used in a hole? With float switch control, plus time relay 24 hours, every 12 hours at will, you set time, seconds, minutes can be
Q:The diving pump in the aquarium stops and stops on the goldfish
Generally do not close the filter at night, at 56 in the morning when the most likely hypoxia. The sick fish are all fished out. Fast infection
Q:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
The star delta circuit you give belongs to the international standard starting mode, different from the old gb. The first said (the old national standard, is actually the domestic elders step-down manner, they are the main contactor) after shunt implementation of star triangle, so there will be a larger contactor, down economic calculation.And the new international standard (you give the circuit diagram) can be seen that the air switch to select the motor current to meet the given amount of surplus, 90kw motor rated current 175A, so choose 225A air switch can be. 1KM 2KM is the main operation of contactors, contactor, they each pay half the current line in triangle, so choose 110A (like never seen 100A) current, 3KM star, because of short-time current will not cause damage to the contact, a little lower 80A is not affected. Heat meter: if you don't use a transformer, you can choose JR36---160A.Some friends may feel small, in fact as long as you pay attention, you will find a lot of electrical equipment factory are doing this standard. In this way, both cost savings and service requirements are met.
Q:What's the meaning of a single-stage pump?
In fact, the simplest difference between multi-stage pumps and single-stage pumps is that more than one impeller and one impeller can be summarized.The so-called single-stage pump is the pump inside only one impeller pump, so that we can be referred to as a single-stage pump, which is characterized by the head is not high, but the flow rate could reach thousands of square per hour, the typical model is the ISG type single-stage centrifugal pump.The pump is a pump body which contains a plurality of impeller pumps, pump is characteristic of such a large flow and high lift, traffic can be thousands of square kilometers to the head, but the cost is not low, customers should be chosen according to the actual parameters.
