Preferably, the quantity of the membrane junk ring bolt is specially four, four membrane junk ring bolts and the pump
The position of hook bolt is non-interference.
After the structure of the utility model, after the medicament of metering pump conveying has high viscosity, in hydraulic pump head
Portion space especially stops a period of time, inside hydraulic pump head afterwards for a period of time there are certain medicament residual in metering pump operation
It can there are substantial amounts of crystalline solid, it is necessary to could be used after being cleaned to hydraulic pump head inside；Due to the presence of membrane pressure ring,
When dismantling pump head body, membrane is still firmly pushed down by membrane pressure ring, can effectively solve to clean pump head sheet in the prior art
Body, the problem of diaphragm assembly must be replaced every time；Using this structure without diaphragm assembly is needed to change, improve work efficiency and drop
Low equipment management cost, meanwhile, the utility model simple structure is easy to spread；To sum up, when cleaning pump head, without tearing open
Membrane is unloaded, so that cleaning is simple, and the maintenance cost of pump head is low.
