PG / PM series clean water pump: a single-stage single suction horizontal centrifugal pump is mainly used for pumping water at room temperature, is widely used in water supply, cooling and other systems and machinery, equipment. Main features: 1. Easy installation: coaxial pump and motor, no adjustment axis; 2, compact structure: Direct horizontal centrifugal pump, compared with conventional single-stage centrifugal pump, can save more than 50% area , reduced by more than 35% by weight; 3, long life: Compared with ordinary single-stage centrifugal pump, low noise, high efficiency, greatly extending the life of the pump. 4, the technical parameters: Diameter: 25 to 50 mm flow: 3.5 ~ 15 m3 / h Head: 6 ~ 32 m speed: 2900 r / min Motor power: 0.75 kw ~ 1.5 kw media requirements: water ≤80 ℃ or similar installation and requires liquid water pump: 1. Install height should be less than the allowable suction on the vacuum inlet pipe height minus losses. 2. Pump outlet flange on the pressure gauge should be installed in order to observe and control the operating conditions of the pump; 3. the weight of the pipe from the pump must not bear; 4. pumps should be installed in a ventilated area, outdoor installation shield should be added avoid sun exposure and rain; 5. Before installation: should check for deformation or damage in transit, fasteners loose or fall off. 6. Inlet and outlet pipe installation configuration: the pipe should be installed to minimize the pipeline fluid resistance principle. Should be added at the intake pipe filter to prevent impurities or hard rigid solid particles into the pump chamber seal or water damage leaves, causing the pump leaking or abnormal; intake pipe at the check should be added in order to water. 7. Wiring: nameplate requirements must correct wiring, wiring, terminals must be firm, not allowed to have loose, otherwise it will cause poor contact caused by burn-in phase. Overload protection device must be used on the wiring line, and adjust the set value of the protection device size based on the requirements of the current motor nameplate. Start: 1. Before starting the pump inlet valve should be opened and the pump discharge valve plug, close the outlet valve, pump chamber filled with water, the pump can be started normally. 2. Jog motor, check whether the steering direction (from the motor, ie clockwise) run of the arrow: 1. After starting the pump gradually open the outlet valve to adjust to the desired operating point. 2. Pump During operation, operating conditions point to no more than the traffic flow performance parameters given in the table of large flow point is appropriate, while the motor is running current must not exceed the rated current. 3. Stop order: close the valve outlet piping - Motor - gauges Maintenance: 1. should always check whether the pump is running smoothly, with or without mechanical seal wear and leakage, and timely replacement of seals to prevent water from entering the motor pressure . 2. Always check the temperature of the motor housing, the maximum temperature should not exceed 85 ℃, the temperature is too high if found, should immediately stop checking. 3. When the pump a long time out, you should drain the water, to the rust scale, painted with anti-rust oil for the next reuse.
