What are some advantages heat pump preventive maintenance? - - - - - -

heat pump is a new type of pump, through the working principle of magnetic couplings can transfer torque without contact. When the prime mover driving electric magnetic steel rotor, electric magnetic steel rotor under the action of magnetic field in synchronous rotation, and the electric magnetic steel rotor connected with the impeller. As a whole, so as to achieve the purpose of the impeller non-contact drive. Because of liquid sealed in fixed of sleeve, so the heat pump is completely closed without leakage of the pump, thus completely eliminate the mechanical seal centrifugal pump inevitably run, take, drop and leakage.

heat pump over-current components made of stainless steel ( 30 316 l) , widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense and other fields. It is flammable, explosive, toxic and valuable liquid. Is to create the ideal equipment without leakage, the ideal choice for pollution-free civilization workshop.

after long-term use, heat water pump also need to regular maintenance and overhaul of operators, the main points are as follows:

1, if you don't use for a long time, the heat pump should be kept in a safe place, and the equipment can be placed in a dry, clean and no corrosion environment.

2, to heat pump lubrication, regularly to ensure that the bearing lubrication clean and pay attention on the replacement.

3, regular maintenance and repairing heat pump. Maintain content including: internal wiring, plugs, switches are in good condition, whether the insulation resistance is normal, brush the tailstock is loose, commutator and brush contact is good, whether the armature winding the stator winding. Whether to have the appropriate interrupt, bearing and rotating parts for damage, etc.

4, pay attention to the insulation resistance, heat pump use or not to be used in damp environment for a long time of electric pump. Before using, must use 500 v megohmmeter measure the insulation of the winding resistance. If the insulation resistance between the winding and the motor shell is less than 7 trillion euro, it must be dry and winding.

5, save each parts and the exchange of the same parts. Remove the gear oil pump, should hold each parts. It is important to pay special attention to the explosion-proof explosion-proof surface of the parts, including insulation gasket and the shell of the brush can't make it. If there is any damage, it must be replaced a new parts. Shall not be used below the raw materials or parts is not in conformity with the original performance specifications of the alternative materials. All parts shall be assembled in the assembly process shall be carried out in accordance with the original position, and shall not be missed.

There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their winter cover pump effects. However, recent studies have provided valuable insights into how the intake of may result in improved pool cover drain pump.
J&T INDUSTRY CO.,LTD. has been a leading server of for many years. Visit the website J&T INDUSTRY for quality water pump.
Apart from this, exhibit myriad winter cover pump benefits, like the prevention of pool cover drain pump by enhancing winter cover pump.
