Fault Analysis and Elimination of Cast Iron Electric Diaphragm Pump
Cast iron electric diaphragm pump is a type of electric diaphragm pump, metal structure to ensure the service life and quality of products, especially in recent years, the use of diaphragm material made a breakthrough, this type of pump Pu made a good development. Cast iron electric diaphragm pump with careful ability, anti-leakage, for a wide range of applications, is widely used in petroleum, ceramics, painting, sewage treatment and other industries. Cast iron electric diaphragm pump in the use of a long time after the failure, in particular, the temperature of the motor the most prominent problem, we have to address this issue to analyze and explore solutions. Cast iron electric diaphragm pump motor temperature reasons: 1. Cooling system water or insufficient cooling water; 2. Water temperature meter instructions are not allowed or failure; 3. Cooling system scale too much, poor cooling effect; 4. Radiator shield mesh or The radiator core air duct blocked by debris, resulting in poor cooling; 5 pump, fan belt too loose or broken; 6 pump damage, fan blades installed anti or deformation, damage to the air ring; 7 thermostat damage in the main valve Close position; 8. Long-term overload of the engine and fuel supply time is too late. Cast iron electric diaphragm pump motor temperature is too high Exclusion: When the motor appears in the work water temperature is too high, you should observe the phenomenon of failure to find out the reasons to be ruled out. First, check the water temperature meter is not working, if not allowed or failure should be replaced; and then check whether the water tank is short of water, water pipe, radiator rupture leakage, in addition to direct observation from the outside, but also to cheer method to check the leak site. Radiator leaks can be repaired with soldering, such as a heat pipe rupture heavier, two-head clamp can be blocked. Found a slight leakage of work, can be blocked with soap, to be repaired after parking. If not for the above reasons, should further check the engine casing for cracks, water blocking ring is damaged, but also to check whether the pump drain hole leaks. Finally check the radiator cover exhaust valve failure, such as failure should be replaced. If the issue of non-cooling water leakage, the fault should be analyzed and excluded in two cases. Suddenly the water temperature is too high. First check whether the radiator is overheated, if the radiator temperature is too high, indicating that the cylinder pad washed, check the body at this time the plane and the cylinder cover with serious warpage, if the deformation should be promptly repaired. If the radiator temperature is not high, then the cooling water circulation is bad, you should check the fan belt is broken or severe slippery. If normal, then check the radiator outlet tube is suction deflated, with or without delamination plugging, to find out the reasons to be ruled out, the emergency approach is to put in the deflated tube appropriate large spring support. Then check the thermostat expansion tube rupture, rupture should be replaced. If the thermostat is normal, then the diaphragm pump is damaged, you should carefully check and repair the pump. 2. Suddenly the water temperature is too high. For not suddenly the phenomenon of temperature is too high, you should increase the engine speed to observe the water inlet is turned over, while paying attention to a large number or a small amount of water. If a large number of water, and uneven radiator temperature, then some of the cooling pipe is blocked, should pay attention to the cold winter. When a small amount of water inlet nozzle and the engine temperature before and after the low, then the sub-pipe has been damaged or blocked, should be promptly replaced. If not for the above reasons, the cooling system may be excessive scale, poor waterway. If the water does not turn over the water, you should look at the cooling system and engine mechanical parts carefully analyzed. First of all, check whether the shutter is closed or the opening degree is less than the fan rotation is normal, if everything is normal, and the engine is still overheating, you should check the fan air flow. If the air volume is insufficient, the angle of the fan blades should be adjusted, and the blade blades should be properly bent or transformed. In the normal cooling system, the engine is still overheating, you should consider the use of the reasons. Cast iron electric diaphragm pump heating is due to a variety of reasons, according to specific problems, specific analysis, in order to come to the final solution, the above is only some of the methods provided to you, for reference only.
