PP filter pumps parsing - in use process pay attention to the problem 【 3 m filter.

Pp filter manufacturers can not leak, leakage, otherwise it will damage the pump inlet of vacuum degree, reduce water pump water yield, serious when even tied up. Suction piping requires strict sealing, device technology from the pipe. Therefore, to seriously do a good job in pipeline interface ensure the construction quality of pipe connection.
pumping plant site elevation and water temperature is different from the test conditions, it should be noted. Such as local 300 meters above sea level or by pumping water temperature above 20 degrees Celsius, the calculated value will be revised. Is that the atmospheric pressure and at different elevation height of the more than 20 degrees Celsius temperature of saturated steam pressure. But when water temperature is 20 degrees Celsius, saturated vapor pressure can be ignored.
pp filter device technology is the key to determine the pump installation height. This height is refers to the water surface vertical distance to the center line of the pump impeller. Pump nameplate or label on product manual allow the vacuum suction height refers to the vacuum pump inlet section on value, and it is under standard atmospheric pressure; The water temperature is 20 degrees Celsius, test and measurement and later did not consider water pipe flow situation. And pumping plant height should be allowed on vacuum suction height after the suction pipe head loss, the remaining portion of the values, to overcome the actual water terrain height. Pumping plant height cannot override calculated value, otherwise, the pump can't will spring up. In addition, influence the size of the calculated value is the resistance of the suction pipe head loss, therefore, appropriate USES shorter pipeline arrangement, and try to minimize the fittings such as elbow, also can consider the appropriate with larger diameter of the pipe, to reduce tube flow velocity.
pp cotton filter even guiding type can also control in a few milliseconds. Because of its circuit, response time can be short as a few milliseconds. Filter more sensitive than other automatic control valve of the reaction. Properly designed coil power consumption is low, belong to energy-saving products; Can also be simply trigger action, adhere to the valve position automatically, no electricity at ordinary times. Pp filter shape size, save a space, light and beautiful again.
by electric, pneumatic, hydraulic actuators to control valve core rotation or movement. This is caused by the valve stem seal to solve the leakage problem; Only pp filters are electric magnetic force acting on the seal in the magnetic separation casing of iron core, internal and external leakage is essential to threaten the peace. Other automatic control valve stem is usually stretched out. There is no dynamic seal, plugging leakage easily so. Within the electric valve torque control is not easy, easy to leak, even to break the stem head; Structure is easy to control the internal leakage to zero. So, pp filter using a special Christmas, especially suitable for corrosive, toxic, or high and low temperature medium. The price also low simple structure itself. Compared with the regulator device such as a other kinds of actuators is easy to maintain. More prominent of automatic control system is much simpler, much lower prices. Due to the pp filter is switch signal control, connection with industrial control computer is very convenient.
