Beijing sewage pump sewage pump sales service

Beijing installed sewage pump sewage pump sewage pump maintenance |. Presidential Beijing Hengtong Technology Co., Ltd. to provide you with a wealth of information and information on other aspects of 13,522,628,596. Submersible pump device consists of pumps, motors, water pipelines, waterproof cables and a control switch has five major components, water pump for the single-suction multi-stage vertical centrifugal pump. 2. Submersible motor with flushing wet type, the cavity is filled with water, mainly for motor cooling and bearing lubrication. When during operation due to temperature changes, pressure changes caused by flushing the motor cavity, the lower end of the motor can be adjusted automatically regulating device. 3. In order to prevent sand intrusion motor, the motor with the top dumped sand and seal, composed of sand prevention agency, the entire electrical engineering seal structure. 4. Motor top with water and vent holes, the bottom has drainage holes. 5. The motor is equipped with the lower part of the thrust bearing thrust plate level, mainly exposed to pump the remaining axial force and the weight of the motor rotor. 6. The motor stator windings waterproof wire, with good insulation and water resistance, as the squirrel cage rotor structure. Compact and lightweight submersible pumps, plays an important role in rural production and living, in use should note the following. First, buy the submersible pump should pay attention to the model, flow and head. Such as the use of inappropriate specifications will not get enough out of water, you can not play the efficiency of the unit. In addition, it should clarify the direction of rotation of the motor, some type of submersible water pumps Jieke forward and reverse rotation, but reversed the small amount of water, current, its reversal will damage the motor windings. To prevent leakage in underwater submersible pumps work result in electrical shock, leakage protection switch should be installed. Second, when you install submersible pump cables to overhead power line is not too long. Do not force the cable when the crew into the water, avoid power line break. Submersible pumps do not sink into the mud, otherwise it will lead to poor heat and burn out the motor windings. Third, try to avoid the power at low pressures. Power supply voltage and rated voltage not a difference of 10% voltage too high will cause the motor to overheat and burn out the windings, the voltage drops too low, the motor speed, such as not reach the rated speed of 70%, start centrifugal switch closes, causing the start winding long power and heat and even burn the windings and capacitors. Do not switch the motor frequently, it is because it will produce reflux pump stopped, if start immediately, will start the motor load, leading to start winding current is too large to burn. Fourth, do not let the pump long-term overload, do not smoke sediment large water pump dehydration running time not too long, so as not to cause motor overheating and burning. Within the unit in operation, the operator must always observe whether the operating voltage and current values ??specified on the nameplate, G-type single screw pump should not meet the motor stops running, determine the cause and troubleshooting. Fifth, more than usual, check the motor, as found under the lid cracks, rubber seal ring damage or failure, etc., should be replaced or repaired to prevent water infiltration machine repair all kinds of submersible pumps, sewage pumps, deep well pump, mud pump, hydraulic pump , centrifugal pumps, pipeline pumps, circulating pumps, booster pumps, heat pumps, shielding pumps, pump, multistage pump, vortex pump, plastic pump, stainless steel pumps, magnetic pump, fluorine alloy pump, pump thick, gear pumps , machine pumps, barrel pumps, automatic pumps, pressure pumps, vacuum pumps, etc., 2, exhaust fan, exhaust fan louvers, explosion-proof exhaust fan, axial fans, from temperature axial fans, explosion-proof fans, explosion-proof industrial fans, anticorrosive fans , centrifugal fan, low noise fan, the wind chassis, fan pressure, high pressure air, mixed flow fans, air-conditioning fan, imported fans, vortex blower, etc. 3, Motor: a variety of medium-sized motors, generators, welding machines.
