Blowdown pump electric machinery lacks photograph etc issue

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The blowdown pump that is a major produces manufacturer. When type selecting of client blowdown pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of blowdown pump model, blowdown, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that lacks photograph etc issue about blowdown pump electric machinery:

▼ problem one: Blowdown pump electric machinery is abrupt power source tripping operation
If the power source protector of place form a complete set and water pump electric machinery are of be identical, below normal circumstance, protector is won’t of tripping operation. The main reason of protector tripping operation has:
1, overload of water pump electric machinery;
2, temperature rise of water pump electric machinery is exorbitant;
3, electric current of movement of water pump electric machinery is too big;
4, the power source voltage of form a complete set of water pump place is exorbitant.
▼ problem 2: Overload of the electric machinery when blowdown pump works
General electric machinery has a rated moving power, those who say for rated power, the unit is watt (W) or kilowatt (KW) . If under certain circumstance, make the rated power of runs power actually to exceed water pump form a complete set of electric machinery, criterion this kind of circumstance calls electric machinery overload. Electric machinery overload has form of the following kinds of expression:
1, quantity of heat of electric machinery hair is too big;
2, electric machinery rotate speed drops, drop even reach rotate speed for 0, expression does not turn for electric machinery;
3, electric machinery has buzzing low song, at the same time companion has bigger vibration;
4, electric machinery load is acuteness change, rotate speed of meeting occurrence electric machinery ignore tall ignore low circumstance.
▼ problem 3: Blowdown pumpElectric machinery of the three-phase when movement is short of
Three-phase electric machinery must provide drive power source by 3 cable when movement, ability achieves three-phase to run evenly; If offer power source to also can run by two power supply cord, but because be short of electric machinery of photograph burn down,locomotive time lengthen can cause electric machinery. Differentiate electric machinery lacks photograph method:
1, the tension that uses all-purpose watch to measure 3 power supply cord, whether to press fall;
2, examine the cupreous silk inside 3 power supply cord, whether among them two power supply cord are nigrescent, the cupreous silk of a power supply cord is done not have nigrescent keep unvarnished;
3, open electric machinery antrum, usually the two-phase of three-phase electric machinery is met burn down, another photograph keeps unvarnished.
▼ problem 4: Blowdown pump electric machinery drinks water
Be in usually, water pump electric machinery is not to allow those who drink water (leach pump is exceptional) . Electric machinery has the following kinds of cases into water:
1, waterproof cable damaged drinks water;
2, wiring of power supply cord of water pump electric machinery is done not have sealed good into water;
3, water pump electric machinery is in sealed structure attaint to drink water into the line;
4, water pump machinery is sealed attaint drinks water;
5, attaint of water pump O sealing ring drinks water;
6, sealed place bolt did not screw bring about electric machinery to drink water;
7, water of ooze of attaint of water pump spare parts.
▼ problem 5: Blowdown pump electric machinery has leakage of electricity
Be in usually, water pump electric machinery is won’t of leakage of electricity, but electric opportunity leakage of electricity falls in the following kinds of circumstances:
1, leakage of electricity of waterproof cable damaged;
2, place of wiring of power supply cord of water pump electric machinery does not have sealed good leakage of electricity;
3, water pump electric machinery receives hourglass report;
4, the leakage of electricity after burn down of water pump electric machinery;
5, insulation resistance is too low bring about leakage of electricity.
The person property that leaves in circumstance of electric machinery leakage of electricity to assure water pump is safe, must install the ground connection of water pump correctly, at the same time switch of finer installation leakage of electricity.
▼ problem 6: Blowdown pump electric machinery cannot be started
Opportunity of water pump report does not start (not rotational or rotate speed is too low) general out is the following reason:
1, water pump leakage of electricity;
2, the power source voltage of place form a complete set is too low;
3, water pump impeller gets stuck dead because of the eyewinker;
4, bearing attaint gets stuck dead;
5, electric machinery excess load moves (overload) ;
6, power source of three-phase of three-phase water pump is received instead;
7, three-phase electric machinery is short of;
8, electric machinery sweeps chamber;
9, capacitor attaint, receive instead, the size is too small.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that lacks photograph etc issue about blowdown pump electric machinery, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company still produces the pump below fluid, welcome you at any time seek advice.
