LH76-915B squeeze hose grouting pump for TBM consists mainly of pump house, rotor, roller, idle roller, squeeze tube and driving unit. The squeeze hose is U-shape in pump house, when rotor drives roller to rotate, hose is deformed. After the roller rotate, the deformed hose recover by its elasticity. Thus the negative pressure in this hose is generated, sucking slurries, and discharging through outlet under roller’s push, finally forms pressure conveying of slurries. Along with the cyclic squeezing of roller, the slurry is pumped continually.
► Application:
LH76-915B squeeze hose grouting pump can work as a benonite slurry pump in Tunnel Boring Machine(TBM).Thus the negative pressure in this hose is generated, sucking slurries, and discharging through outlet under roller’s push, finally forms pressure conveying of slurries.
Squeeze hose pump for pumping benonite slurry pump in Tunnel Boring Machine(TBM):
► Features:
2. Squeeze hose pump for TBM can dry-running without damage;
3. No valves;
4. Be reversible;
5. No contact between product and mechanical parts;
6. Pumped material only touches the hose;
7. Only tube to replace;
8. Able to pump products with solid parts inside;
9. Hose Pump for TBM is easy maintenance, low-cost, shot down time.
Advantage of squeeze hose:
● Low accuracy request on squeeze tube;● Squeeze interval adjusted by the eccentric roller;
● Recovery of the squeeze tube against the recovery rollers;
● Natural rubber hose with 4 layer of thread reinforcement as the squeeze hose.
● Squeezed by the squeeze rollers, rolling friction to have the low request on the lubrication;
