Application: Widely used in light industry machinery (injection molding machine, hollow molding machine, die casting machine, shoe machine, etc.). Forging machinery (such as pipe bending, hydraulic press, bending machine, etc.), metallurgical machinery, port machinery and other industries.
Original Manufacturer : NACHI
OEM : HENGTE
● The type of safety valve on the gear oil pump is the spring type safety valve and the one action safety valve. When the discharge pressure of the gear oil pump is less than the reseating pressure of the safety valve, the safety valve will close.
● There is clearly no reseating pressure Ph for a single action safety valve. When the discharge pressure of the gear pump is greater than the start-up pressure Pk, the safety valve opens to release the force to the predetermined level.
PRODUCT DISPLAY
THE FUNCTION OF NACHI BU ER YUE GEAR PUMP
The type of safety valve on the gear oil pump is the positive displacement gear pump. There are two types of safety valves: the spring yellow safety valve and the one action safety valve. The type of safety valve on the gear oil pump is the spring type safety valve and the one action safety valve. When the discharge pressure of the gear oil pump is less than the reseating pressure of the safety valve, the safety valve will close.
There is clearly no reseating pressure Ph for a single action safety valve. When the discharge pressure of the gear pump is greater than the start-up pressure Pk, the safety valve opens to release the force to the predetermined level.
NACHI BIYUE GEAR PUMP HAS BEEN IDLE FOR A LONG TIME AND WILL NOT OPERATE. WHEN IT IS RESTARTED, IT WILL CAUSE THE GEAR PUMP TO FREEZE OR LEAK, AND THE GEAR PUMP WILL HAVE HIGH NOISE.
The main reasons are multiple,Gear oil pump. If the gear pump is idle for a long time and does not rotate far, the rate seal of the gear pump will leak when it rotates far again.
The main reasons are divided into two points: (1) The mechanical seal gear pump will generate carbon deposits due to the long-term accumulation of the conveyed medium in the mechanical seat seal, especially when the mechanical seal pump is conveying high dry materials. If the gear pump is not running for a long time, the materials will stick to the mechanical seal. When the gear train is restarted, it may cause wear on the mechanical end face of the gear train, causing leakage, and in severe cases, it may continue to break the mechanical seal spring of the main gear train, Direct damage to the mechanical seal of the Daochengye snake pump.
When the NACHI Fujitsu gear pump is placed for a long time, due to the repeated use of waste oil from the test bench pool by the gear system manufacturer during the actual supply of the Western wheel pump, it is inevitable that there will be some moisture in the oil. When this part of the oil containing moisture is left in the gear pump for a long time and comes into contact with the gear and pump body for a long time, due to sufficient contact with air gasification and other reasons, the large part of the gear pump will rust within a certain time, This causes the gear pump to not rotate when installed and used, which is common among newly installed customers.
One group of customers who purchase gear to the pump is from the local department, However, often the gear trains they buy are inventory or backlog items of the store owner (as the middle and south parts of the gear pump and gear pump need to have inventory, but the storage time varies). Therefore, it is recommended that customers purchase gear pumps or other gear pumps locally to first check whether the main rotation of the gear pump is working properly and evenly, in order to avoid unnecessary trouble when buying them back
