Blowdown pump uses item daily

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 uses item daily about blowdown pump:

Because cistern is medium,blowdown pump often is met lack water and bring about electric machinery winding to burn out. Be aimed at this kind of circumstance, a few kinds of safeguard that blowdown pump increases: The protection that lack water, electric machinery is slack slack protection, insulation resistance protects protection, oily room, winding overheat protection, bearing overheat protection.
1, prohibit power source voltage is unusual switch on the mobile phone
Because low pressure offers electric line to grow quite, the extreme voltage of circuit is too low it is constant some thing. When phase voltage under 198 bend over, line voltage under 342 bend over when, rotate speed of blowdown pump electric machinery drops, when short of of rated rotate speed 70% when, start centrifugal switch to be able to close, cause start circle electrify of group leader time and calorific burned-out even winding and capacitor. Contrary, voltage is exorbitant cause electric machinery overheat and burned-out winding. Accordingly, blowdown pump is in exercise, handlers must observe power source voltage is worth at any time, if under rated voltage 10% the following, prep above is rated voltage 10% above, should make electric machinery quits movement, find out a reason and remove trouble.
2, the direction of rotation that affirms correct electric machinery
Should make clear the direction of rotation of electric machinery, when pump is turning and inverting, the blowdown that there are a lot of kinds now all can give water, but water goes out to measure small, electric current when inverting big, its reversing time grew winding of meeting attaint electric machinery.
3, the insulation resistance requirement of cable installation and blowdown pump
When installing blowdown pump, cable wants built on stilts, power supply cord does not want too long. Blowdown pumpWhen enter the water or putting forward, do not make cable gets power, lest cause power supply cord,rupture. In mud sinking when blowdown pump works, can bring about electric machinery to come loose otherwise winding of heat is undesirable and burned-out electric machinery. When installation, the insulation resistance of electric machinery do not answer under 0.5 million Europe.
4, avoid frequent switch
Do not want often switch blowdown pump, because electric pump stops the meeting when turning to produce circumfluence,this is, if switch on the mobile phone instantly, can make electric machinery load is started, bring about the electric current that start is too big and burned-out winding. As a result of the electric current when starting very big, start often also can burn out winding of blowdown pump motor.
5, the installation of protector of leakage of electricity
Protector of leakage of electricity also makes maintain an order implement, its action from maintain an order implement these 3 words are understandable. Because blowdown pump works in underwater, easy leakage of electricity causes electric energy loss to cause accident getting an electric shock even. If contain protector of leakage of electricity, the behavioral electric current that wants value of blowdown pump leakage of electricity to exceed protector of leakage of electricity only is worth (do not exceed 30 milliampere commonly) , protector of leakage of electricity can cut off the power source of blowdown pump, ensure safe, avoid leakage of electricity, wasteful electric energy at the same time.
6, prohibit blowdown pump is long-term excess load works
To avoid blowdown pump long-term excess load works, do not smoke sandiness generous water observes whether voltaic value is on nameplate at any time formulary numerical value, if discover electric current is too big, should stop machine examination. Additional, the time that electric pump dehydrate runs shoulds not be too long, lest make electric machinery overheat and burn down.
7, pay attention to safeguard daily
Check electric machinery more at ordinary times, if discover next lids have attaint of seal ring of crackle, balata or invalidation to wait, should change in time or repair, with waterproof infiltration machine.
8, avoid to switch on the mobile phone when low pressure as far as possible
Power source voltage and rated voltage cannot differ 10% , voltage is exorbitant can cause electric machinery overheat and burned-out winding, voltage is too low criterion electric machinery rotate speed drops, if short of is rated of rotate speed 70% when, start centrifugal switch to be able to close, cause start circle electrify of group leader time and calorific burned-out even winding and capacitor. Do not want often switch electric machinery, because electric pump stops the meeting when turning to produce circumfluence,this is, if switch on the mobile phone instantly, can make electric machinery load is started, bring about the electric current that start is too big and burned-out winding.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that uses item daily about blowdown pump, 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 returns production to suck pump oneself, welcome you at any time seek advice.
