Product Structure That
ZJQ submersible slurry pump is my company design, research and development of new type pump, the pump is composed of two parts of the motor and pump, the two separated by oil isolation rooms and mechanical seal components, electromechanical integration products, share the same motor and pump shaft (the rotor) the whole pump length is short, compact structure. Equipped with a variety of protection device, the pump running safety and reliability.
Adopt international motor, Y series F class insulation, safe and reliable operation.
With double tandem seal, selecting new alloy material, with a reliable sealing, wear-resisting, long service life, etc.
Use high chromium slag pulp pump flow components, material, wear-resisting performance is good, the flow performance, is the domestic life of the same type pump 2 to 10 times.
Pump Use Method And Matters Needing Attention
1, check the cable for damage, carefully before trial the fastener is loose or fall off, pump in the process of transport, storage, installation with and without deformation or damage.
2, with 500 v megohmmeter measuring insulation resistance between the same electric pump motor and relatively, the value shall be not less than 2 ohms, or dry processing should be made for motor stator winding, the temperature of the drying process are not allowed to exceed 120 째 C.
After 3, pump through the rotation of the direction from the inlet rotate counterclockwise (6), if the electric pump reversal, just put the cable in any second thread for connection location.
4, electric pump casing with ground wire must be strictly in accordance with relevant regulations, in order to ensure the personal safety when using, the pumps is running, it is forbidden to install or mobile launching of human beings in near one thousand electric pump in case of leakage accident.
5, electric pump in the absence of special circumstances must be equipped with automatic water pump control, do not hang grid directly or use knife switch to switch on the power supply, ensure the normal operation of electric pump.
6, the electric pump must not be long-term running low hm conditions (usually with a head of less than 60% of the rated head), best can control within the scope of the recommended head, in case of electric pump burn out motor due to overload.
7, the circulation cooling device of pump it is forbidden to overall long running out of water, in case of damage to the pumps overheating.
8, the pump equipped with variable frequency speed regulating device, applicable to industrial and mining is more extensive.
Maintenance
1, pumps shall be of personnel management and use, and check the insulation resistance of electric pump winding and the casing is normal.
2, particularly applicable to each use thicker after a sticky slurry pumps should be run into clear water for a few minutes, to prevent the leaves sediment inside pump, electric pump clean.
3, electric pump, such as long time need not when electric pump should be removed from the water, do not soak bubble in the water for a long period of time in order to reduce the chance of motor stator winding be affected with damp be affected with damp, increase the service life of electric pump.
4, in the condition of conventional pump after every use of 300 ~ 500 hours or replacement will be listed in the oil chamber oil (10 ~ 30 oil), keep good lubrication condition, the mechanical seal to improve the service life of mechanical seal.
5, pumps after disassembly, repair, chassis components must be inspected by 0.2 Mpa air test, to ensure that the motor seal and reliable.
6, between the impeller and the pump body sealing ring sealing function, such as sealing damage will directly affect the performance of the pump, should be replaced when necessary.
