Oil filler plug.The invention further relates to a kind of working methods of oil filler plug for truck cap overturning system manual pump.
Background technique
Heavy load truck hydraulic cab overturning system is to be used to overturning forward in maintenance and maintaining card car combustion engine to drive
Room and expose internal combustion engine below, hydraulic overturning system is usually made of manual pump, electrodynamic pump, oil cylinder, hydraulic lock, pipeline
(see figure 8), wherein hand oil pump and electrodynamic pump can be respectively intended to provide hydraulic pressure to oil cylinder come realize driver's cabin lifting and
It falls after rise.Closed hydraulic pressure oil fuel tank is equipped in manual pump (see figure 9), electrodynamic pump shares an oil by fuel sucking pipe and manual pump
Case, oil filler plug are mounted on the manual pump pump housing.
The structure of oil filler plug is using round rubber diaphragm spring and the design of plunger type high-pressure jet proof type structure (see figure at present
10).The use of round rubber diaphragm spring has many drawbacks: one reaches the elasticity of setting because its material is rubber material
Cracking pressure very little, very sensitive to pressure oscillation and environment temperature, the easily oil extraction and exhaust in its expiration, this is resulted in
If client not enough or when refueling excessive will make truck online production, driving process hand occur to the exhaust of overturning system vacuum
Dynamic pump oil filler plug oil leak；The second is the easy large area of its circular configuration is led to seal by booty particle contamination bad and oil leak, leakage
Oil causes components, surrounding enviroment below oil pump and its installation site all to pollute, and influences environmental sanitation and vehicle presentation quality,
Truck client and truck user currently complain oil filler plug oil leak and complain very big.Plunger type high-pressure blowout prevention function is not very real
With.Furthermore the oiling plug structure is extremely complex, and assembly technology is various, so overall cost is high.
