Baoji Coal Mine BQG250/0.4 pneumatic diaphragm pump manufacturer

Baoji Coal Mine B/. Pneumatic Diaphragm Pump Manufacturer 3. Working Principle
The mining pneumatic diaphragm pump uses the pressure difference in the air chamber to alternately generate suction liquid pressure and positive liquid pressure in the liquid chamber. Controlling the valve switch can ensure the normal flow of the liquid. flow towards. After ventilation, the pump starts running and works continuously to ensure that the required pressure remains constant. The pump will increase and maintain the delivery pipe pressure, and when the maximum delivery pipe pressure is reached (or the distribution valve is closed), it will stop working and when needed time, resume pumping.

B/.Pneumatic diaphragm pump manufacturer
Mining pneumatic diaphragm pump
Wei Wei ran off the bridge and smiled: "Brother Nai He has been looking up to me for a long time, why are you calling me?" Yixiao Naihe hummed, and then the system prompted Weiwei: Yixiao Naihe added you as a friend. Weiwei quickly agreed and added a smile of Naihe. It is not so easy to add Yixiao Naihe. Mining Pneumatic Diaphragm Pump
The friend switch of top experts is always turned off. Weiwei sometimes turns it off when there are too many people adding it. Yixiao Naihe sent a message after a while: "What do you think of this wedding?" Pneumatic diaphragm pump for mining
2. Main features
B/. The pneumatic diaphragm pump uses air flow to push the valve core to reciprocate, so that the pressure air alternately enters the left and right air chambers, causing it to push the diaphragm back and forth. The movement causes a pressure difference in the working chamber to achieve the purpose of water absorption and drainage. It is small in size, light in weight, and does not require a foundation. It can be used as a mobile pump without lubrication. The main valve has no special requirements for the air source and can be started by self-priming. B/. Pneumatic diaphragm pump manufacturer
The diaphragm pump should make no abnormal noise during operation, and there should be no running, popping, dripping or leaking in any part. The pressure gauge and control valve should work reliably, and all performance indicators should meet the rated capacity in the manual or be able to meet production requirements. But failures can also occur due to normal wear and tear or the aging of component materials.
Diaphragm pump pressure is insufficient or increased, causes and treatment methods:
, pneumatic diaphragm pump pressure regulating valve is improperly adjusted; adjust the pressure valve to the required pressure
, pressure regulating valve failure; maintenance pressure Adjust the pressure gauge; repair or replace the pressure gauge
Causes and treatment methods of diaphragm pump pressure drop failure:
, insufficient oil supply in the oil supply valve; repair the oil valve
, insufficient feed or insufficient feed Leakage from the feed valve; inspect the feed situation and the feed valve
and plunger seal for oil leakage; inspect the sealing part
and the oil level in the oil tank is too low; add new oil
and the pump body leaks Or the diaphragm is damaged; check and replace the sealing gasket or diaphragm.
Causes and solutions for insufficient flow of the diaphragm pump:
, the feed and discharge valves are leaking; repair or replace the feed valve
, the diaphragm is damaged; replace the diaphragm
, speed Too slow, adjustment failure; overhaul the control device and adjust the speed.
Causes and treatment methods for oil leakage in diaphragm pumps: The sealing gasket and sealing ring are damaged or too loose; adjust or replace the sealing gasket and sealing ring.
The pneumatic diaphragm pump operates, but the flow rate is small or no liquid flows out at all:
Check the cavitation phenomenon of the pneumatic diaphragm pump, reduce the speed of the pump to allow liquid to enter the liquid chamber.
.Check whether the valve ball is stuck. If the operating fluid is incompatible with the pump's elastomer, the elastomer will swell. Please replace the elastomer with an appropriate material.
.Check whether the joint at the pump inlet is completely locked and leak-proof, especially the clamp near the valve ball at the inlet end needs to be locked.
The air valve of the pneumatic diaphragm pump is frozen: check whether the moisture content of the compressed air is too high, and install air drying equipment
There are bubbles at the outlet of the pneumatic diaphragm pump: check whether the diaphragm is ruptured, and check whether the clamp is Lock, especially the inlet pipe clamp.
The product flows out from the air discharge port: check whether the diaphragm is broken, and check whether the diaphragm and the inner and outer clamping plates are clamped on the shaft
The valve makes a rattling sound: increase the outlet or inlet lift.
Pneumatic Diaphragm Pump Disassembly and Reassembly Guide:
Warning: Before repairing the pump, the air source piping must be removed from the pump and the air pressure in the pump must be discharged. Remove all lines connecting the inlet and outlet of the pump and drain the fluid from the pump to a suitable container. Wear protective hats, glasses, and gloves
The pump does not move or operates very slowly:
Check the filter or air filter device at the air inlet end for any impurities.
.Check whether the air valve is stuck and clean the air valve with cleaning fluid.
.Check the air valve for wear and replace it with new parts if necessary.
.Check the condition of the sealing parts of the center body. If it is severely worn, the sealing effect cannot be achieved, and the air will be discharged from the air outlet end. Due to its special construction, please only use circles.
.Check whether the piston movement in the air valve is normal.
.Check the type of lubricating oil. If you add lubricant with a higher viscosity than the recommended oil, the piston may become stuck or not operate properly. It is recommended to use light and anti-freeze lubricant.
1. Overview
The B/. diaphragm pump produced by our company adopts, absorbs and improves the most advanced pneumatic diaphragm pump production process and technology in the world. This product is specially designed for coal mines and has traditional All the functions of submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps are a revolution in traditional mining water pumps. The key is to completely solve the safety issues of traditional water pumps. The product can provide high conveying speeds at low air pressures and is compatible with a wide range of materials. This water pump has an anti-stall design and a modular pneumatic motor/fluid part.
B/. Pneumatic diaphragm pumps are used to discharge clean water underground in coal mines, or sewage containing solid particle impurities (volume concentration less than %). They can also be used in non-coal mines and other occasions with similar transmission media.
) Pneumatic diaphragm pumps are powered by compressed air. Proper lubrication can make the operation of the pump more stable and extend the service life of the pump. ) Make sure the compressed air is clean. Unclean gas can easily wear the air valve. It is recommended to install a pneumatic triplet! ) The machine needs to be turned on and off slowly to reduce the impact on the pipeline and diaphragm. Check whether the pipeline connection is loose before starting the machine. ) When transporting hazardous liquids, please connect the exhaust of the pump to a safe place to avoid danger when the diaphragm is damaged. ) Please clean it in time after transporting liquid that is easy to dry out to avoid damaging the diaphragm or being unable to start the next time. ) When the pipeline is long, the pipeline must be fixed and a pump cannot be used to bear the weight and vibration of the pipeline.
