The use of filter press is special pump power how to calculate

filter press is special pump start-up operation and maintenance

press filter connected after the special pump pipe road, entered the stage of operation, should pay attention to the following: the view of 'before the trial operation should dish with the hand first before coupling or shaft, such as plate fixed or have different ring, should be timely check, check to see if the coupling of the system is in place, smooth side view the side plate, if the problem still exists, dismantle the pump examining, clean house, and contact the company to negotiate the solution. Driving steps will pump cavity filled with liquid. The pump inlet valve fully open; Open pump for the first time point move power supply, check the pump to whether it is right, open after confirm the correct power supply; Slowly open outlet valve, pressure to adjust to the required operating conditions. Operation on 20 minutes shall check the bearing temperature condition.

down slowly closed outlet valve first, and closed all the instruments. Cut off power supply, and promptly closed inlet valve and the closed cooling water if the ambient temperature below the freezing point temperature, emptying liquid pump cavity, avoid frozen medium in the pump cavity, result in pump damage. If without downtime for a long time, it should be emptying liquid in the pump cavity, with clear water is rinsed clean. The valves on the suction pipe shall not be used to control flow, avoid presenting cavitation; Special filter press pump shall not be under the condition of 30% below pump planning flow after operation; If the traffic is too big, must be set on the discharge pipe by-pass pipe, residual flow discharge. If there is abnormal sound in operation, or a motor the abnormal condition appear such as fever, also should stop check.

progress of filter press the use of special pump power

to improve the pipeline system, cutting resistance. Line length should shorten as far as possible, and adhere to the line, to cut down velocity along the water head loss; Cut gate valve, bottom valve, elbow, the number of orifice plate etc, to cut part of the water head loss. Down the pump discharge pressure of solid volume, appropriately satisfaction piping system requirement for the water pressure. If the pump pressure, large amount of solid pressure pump system of the water pressure is higher than demand, this involves necessary to adopt the valve throttle methods such as little step-down, formation of power abuse. Then measures must be adopted for water pumps, desulphurization pumps, if excess pressure is not too big, can be adopted method for decompression, turning impeller press filter in the system equipment dedicated pump operation as far as possible in the best power point of the water pump, avoid operation under large flow or small flow.
